  - execute
```
public boolean execute(String p_sql)
                throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Executes the given SQL statement, which may return multiple results. In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.
    The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).
    Note:This method cannot be called on a PreparedStatement or CallableStatement.
    
    Specified by:
    
    execute in interface Statement
    
    Parameters:
    p_sql - any SQL statement
    
    Returns:
    true if the first result is a ResultSet object; false if it is an update count or there are no results
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement, the method is called on a PreparedStatement or CallableStatement

  - setCursorName
```
public void setCursorName(String name)
                   throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods. This name can then be used in SQL positioned update or delete statements to identify the current row in the ResultSet object generated by this statement. If the database does not support positioned update/delete, this method is a noop. To insure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should have the form SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may fail.
    Note: By definition, the execution of positioned updates and deletes must be done by a different Statement object than the one that generated the ResultSet object being used for positioning. Also, cursor names must be unique within a connection.
    
    Specified by:
    
    setCursorName in interface Statement
    
    Parameters:
    name - the new cursor name, which must be unique within a connection
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - getUpdateCount

public int getUpdateCount()
                   throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the current result as an update count; if the result is a ResultSet object or there are no more results, -1 is returned. This method should be called only once per result.
    
    Specified by:
    
    getUpdateCount in interface Statement
    
    Returns:
    the current result as an update count; -1 if the current result is a ResultSet object or there are no more results
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    See Also:

  - getMoreResults
```
public boolean getMoreResults()
                       throws SQLException
```
    Description copied from interface: java.sql.Statement
    Moves to this Statement object's next result, returns true if it is a ResultSet object, and implicitly closes any current ResultSet object(s) obtained with the method getResultSet.
    There are no more results when the following is true:
```
     // stmt is a Statement object
     ((stmt.getMoreResults() == false) && (stmt.getUpdateCount() == -1))
 
```
    Specified by:
    
    getMoreResults in interface Statement
    
    Returns:
    true if the next result is a ResultSet object; false if it is an update count or there are no more results

  - getMaxRows
```
public int getMaxRows()
               throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the maximum number of rows that a ResultSet object produced by this Statement object can contain. If this limit is exceeded, the excess rows are silently dropped.
    
    Specified by:
    
    getMaxRows in interface Statement
    
    Returns:
    the current maximum number of rows for a ResultSet object produced by this Statement object; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    See Also:

```
public void setMaxRows(int max)
                throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets the limit for the maximum number of rows that any ResultSet object generated by this Statement object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped.
    
    Specified by:
    
    setMaxRows in interface Statement
    
    Parameters:
    max - the new max rows limit; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the condition max >= 0 is not satisfied

  - setEscapeProcessing
```
public void setEscapeProcessing(boolean enable)
                         throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets escape processing on or off. If escape scanning is on (the default), the driver will do escape substitution before sending the SQL statement to the database. Note: Since prepared statements have usually been parsed prior to making this call, disabling escape processing for PreparedStatements objects will have no effect.
    
    Specified by:
    
    setEscapeProcessing in interface Statement
    
    Parameters:
    enable - true to enable escape processing; false to disable it
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getQueryTimeout
```
public int getQueryTimeout()
                    throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the number of seconds the driver will wait for a Statement object to execute. If the limit is exceeded, a SQLException is thrown.
    
    Specified by:
    
    getQueryTimeout in interface Statement
    
    Returns:
    the current query timeout limit in seconds; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    See Also:
    Statement.setQueryTimeout(int)
  - setQueryTimeout
```
public void setQueryTimeout(int seconds)
                     throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets the number of seconds the driver will wait for a Statement object to execute to the given number of seconds. By default there is no limit on the amount of time allowed for a running statement to complete. If the limit is exceeded, an SQLTimeoutException is thrown. A JDBC driver must apply this limit to the execute, executeQuery and executeUpdate methods.
    Note: JDBC driver implementations may also apply this limit to ResultSet methods (consult your driver vendor documentation for details).
    Note: In the case of Statement batching, it is implementation defined as to whether the time-out is applied to individual SQL commands added via the addBatch method or to the entire batch of SQL commands invoked by the executeBatch method (consult your driver vendor documentation for details).
    
    Specified by:
    
    setQueryTimeout in interface Statement
    
    Parameters:
    seconds - the new query timeout limit in seconds; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the condition seconds >= 0 is not satisfied

    Statement.getQueryTimeout()
  - getQueryTimeoutMs
```
public int getQueryTimeoutMs()
                      throws SQLException
```
    The queryTimeout limit is the number of milliseconds the driver will wait for a Statement to execute. If the limit is exceeded, a SQLException is thrown.
    
    Returns:
    the current query timeout limit in milliseconds; 0 = unlimited
    
    Throws:
    
    SQLException - if a database access error occurs
  - setQueryTimeoutMs
```
public void setQueryTimeoutMs(int millis)
                       throws SQLException
```
    Sets the queryTimeout limit
    
    Parameters:
    millis - - the new query timeout limit in milliseconds
    
    Throws:
    
    SQLException - if a database access error occurs
  - addWarning
```
public void addWarning(SQLWarning warn)
```
    This adds a warning to the warning chain. We track the tail of the warning chain as well to avoid O(N) behavior for adding a new warning to an existing chain. Some server functions which RAISE NOTICE (or equivalent) produce a ton of warnings.
    
    Parameters:
    warn - warning to add
  - getWarnings
```
public SQLWarning getWarnings()
                       throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the first warning reported by calls on this Statement object. Subsequent Statement object warnings will be chained to this SQLWarning object.
    The warning chain is automatically cleared each time a statement is (re)executed. This method may not be called on a closed Statement object; doing so will cause an SQLException to be thrown.
    Note: If you are processing a ResultSet object, any warnings associated with reads on that ResultSet object will be chained on it rather than on the Statement object that produced it.
    
    Specified by:
    
    getWarnings in interface Statement
    
    Returns:
    the first SQLWarning object or null if there are no warnings
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getMaxFieldSize
```
public int getMaxFieldSize()
                    throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, NCHAR, NVARCHAR, LONGNVARCHAR and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.
    
    Specified by:
    
    getMaxFieldSize in interface Statement
    
    Returns:
    the current column size limit for columns storing character and binary values; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    See Also:
    Statement.setMaxFieldSize(int)
  - setMaxFieldSize
```
public void setMaxFieldSize(int max)
                     throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets the limit for the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, NCHAR, NVARCHAR, LONGNVARCHAR and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256.
    
    Specified by:
    
    setMaxFieldSize in interface Statement
    
    Parameters:
    max - the new column size limit in bytes; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the condition max >= 0 is not satisfied

  - clearWarnings
```
public void clearWarnings()
                   throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement object.
    
    Specified by:
    
    clearWarnings in interface Statement
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getResultSet
```
public ResultSet getResultSet()
                       throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the current result as a ResultSet object. This method should be called only once per result.
    
    Specified by:
    
    getResultSet in interface Statement
    
    Returns:
    the current result as a ResultSet object or null if the result is an update count or there are no more results
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    See Also:
    Statement.execute(java.lang.String)
  - close
```
public void close()
           throws SQLException
```
    Note: even though Statement is automatically closed when it is garbage collected, it is better to close it explicitly to lower resource consumption. Releases this Statement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources.
    Calling the method close on a Statement object that is already closed has no effect.
    Note:When a Statement object is closed, its current ResultSet object, if one exists, is also closed.

```
public void setPrepareThreshold(int newThreshold)
                         throws SQLException
```
    Description copied from interface: PGStatement
    
    Sets the reuse threshold for using server-prepared statements.
    If threshold is a non-zero value N, the Nth and subsequent reuses of a PreparedStatement will use server-side prepare.
    If threshold is zero, server-side prepare will not be used.
    The reuse threshold is only used by PreparedStatement and CallableStatement objects; it is ignored for plain Statements.
    
    Specified by:
    
    setPrepareThreshold in interface PGStatement
    
    Parameters:
    newThreshold - the new threshold for this statement

    Description copied from interface: java.sql.Statement
    
    Adds the given SQL command to the current list of commmands for this Statement object. The commands in this list can be executed as a batch by calling the method executeBatch.
    Note:This method cannot be called on a PreparedStatement or CallableStatement.
    
    Specified by:
    
    addBatch in interface Statement
    
    Parameters:
    p_sql - typically this is a SQL INSERT or UPDATE statement
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement, the driver does not support batch updates, the method is called on a PreparedStatement or CallableStatement

    Specified by:
    
    clearBatch in interface Statement
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the driver does not support batch updates

  - executeBatch
```
public int[] executeBatch()
                   throws SQLException
```
    Description copied from interface: java.sql.Statement
    Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:
    1. A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
    2. A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown
      If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
    3. A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails
    The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to proccess commands in a batch update after a BatchUpdateException obejct has been thrown.
    Specified by:
    
    executeBatch in interface Statement
    
    Returns:
    an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the driver does not support batch statements. Throws BatchUpdateException (a subclass of SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.

    Gives the driver a hint as to the direction in which rows will be processed in ResultSet objects created using this Statement object. The default value is ResultSet.FETCH_FORWARD.
    Note that this method sets the default fetch direction for result sets generated by this Statement object. Each result set has its own methods for getting and setting its own fetch direction.
    
    Specified by:
    
    setFetchDirection in interface Statement
    
    Parameters:
    direction - the initial direction for processing rows
    
    Throws:

    Description copied from interface: java.sql.Statement
    
    Requests that a Statement be pooled or not pooled. The value specified is a hint to the statement pool implementation indicating whether the applicaiton wants the statement to be pooled. It is up to the statement pool manager as to whether the hint is used.
    The poolable value of a statement is applicable to both internal statement caches implemented by the driver and external statement caches implemented by application servers and other applications.
    By default, a Statement is not poolable when created, and a PreparedStatement and CallableStatement are poolable when created.
    
    Specified by:
    
    setPoolable in interface Statement
    
    Parameters:
    poolable - requests that the statement be pooled if true and that the statement not be pooled if false
    
    Throws:

    Description copied from interface: java.sql.Wrapper
    
    Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.
    
    Specified by:
    
    isWrapperFor in interface Wrapper
    
    Parameters:
    iface - a Class defining an interface.
    
    Returns:
    true if this implements the interface or directly or indirectly wraps an object that does.
    
    Throws:
    
    SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

```
public <T> T unwrap(Class<T> iface)

```
    Description copied from interface: java.sql.Wrapper
    
    Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
    
    Specified by:
    
    unwrap in interface Wrapper
    
    Parameters:
    iface - A Class defining an interface that the result must implement.
    
    Returns:
    an object that implements the interface. May be a proxy for the actual implementing object.
    
    Throws:

    Description copied from interface: java.sql.Statement
    
    Specifies that this Statement will be closed when all its dependent result sets are closed. If execution of the Statement does not produce any result sets, this method has no effect.
    Note: Multiple calls to closeOnCompletion do not toggle the effect on this Statement. However, a call to closeOnCompletion does effect both the subsequent execution of statements, and statements that currently have open, dependent, result sets.
    
    Specified by:

    Description copied from interface: java.sql.Statement
    Moves to this Statement object's next result, deals with any current ResultSet object(s) according to the instructions specified by the given flag, and returns true if the next result is a ResultSet object.
    There are no more results when the following is true:
```
     // stmt is a Statement object
     ((stmt.getMoreResults(current) == false) && (stmt.getUpdateCount() == -1))

    Parameters:
    current - one of the following Statement constants indicating what should happen to current ResultSet objects obtained using the method getResultSet: Statement.CLOSE_CURRENT_RESULT, Statement.KEEP_CURRENT_RESULT, or Statement.CLOSE_ALL_RESULTS
    
    Returns:
    true if the next result is a ResultSet object; false if it is an update count or there are no more results
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the argument supplied is not one of the following: Statement.CLOSE_CURRENT_RESULT, Statement.KEEP_CURRENT_RESULT or Statement.CLOSE_ALL_RESULTS
    
    SQLFeatureNotSupportedException - if DatabaseMetaData.supportsMultipleOpenResults returns false and either Statement.KEEP_CURRENT_RESULT or Statement.CLOSE_ALL_RESULTS are supplied as the argument.

    Note:This method cannot be called on a PreparedStatement or CallableStatement.
    
    Specified by:
    
    executeUpdate in interface Statement
    
    Parameters:
    sql - an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.
    columnNames - an array of the names of the columns that should be returned from the inserted row
    
    Returns:
    either the row count for INSERT, UPDATE, or DELETE statements, or 0 for SQL statements that return nothing
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement, the SQL statement returns a ResultSet object, the second argument supplied to this method is not a String array whose elements are valid column names, the method is called on a PreparedStatement or CallableStatement
    
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - execute
```
public boolean execute(String sql,
              int autoGeneratedKeys)
                throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Executes the given SQL statement, which may return multiple results, and signals the driver that any auto-generated keys should be made available for retrieval. The driver will ignore this signal if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific).
    In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.
    The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).
    Note:This method cannot be called on a PreparedStatement or CallableStatement.
    
    Specified by:
    
    execute in interface Statement
    
    Parameters:
    sql - any SQL statement
    autoGeneratedKeys - a constant indicating whether auto-generated keys should be made available for retrieval using the method getGeneratedKeys; one of the following constants: Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS
    
    Returns:
    true if the first result is a ResultSet object; false if it is an update count or there are no results
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement, the second parameter supplied to this method is not Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS, the method is called on a PreparedStatement or CallableStatement
    
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method with a constant of Statement.RETURN_GENERATED_KEYS
