public abstract class AbstractJdbcDatabase
extends Object
implements Database

    Description copied from interface: Database
    
    If the database supports schemas, test if a given combination of catalog and schema name equals to the default catalog and schema of the current logged in user.
    
    Specified by:
    
    isDefaultSchema in interface Database
    
    Parameters:
    
    catalog - catalog name to be tested
    
    schema - schema name to be tested
    
    Returns:
    
    if the database supports catalogs: true if it is the default schema, false if not. If it does not support schemas, the behaviour of this method is undefined (please call supportsSchemas first!)

  - getMaxFractionalDigitsForTimestamp
```
public int getMaxFractionalDigitsForTimestamp()
```
    Most relational databases support 9 fractional digits, and subclasses must overwrite this method if they support less than that.
    
    Specified by:
    
    getMaxFractionalDigitsForTimestamp in interface Database
    
    Returns:
    
    the maximum number of supported fractional digits in TIMESTAMP columns
  - getDefaultFractionalDigitsForTimestamp
```
public int getDefaultFractionalDigitsForTimestamp()
```
    SQL Standard (Foundation) says: "...if is not specified, then 6 is implicit."
    
    Specified by:
    
    getDefaultFractionalDigitsForTimestamp in interface Database
    
    Returns:
    
    the default precision / number of maximum digits in a timestamp if nothing else is specified.

    DatabaseException
  - supportsNotNullConstraintNames
```
public boolean supportsNotNullConstraintNames()
```
    Description copied from interface: Database
    
    Does this database treat NOT NULL as an own kind of CONSTRAINT (in addition of simply being a column property)? This will affect the CONSTRAINT clause SQL generators.
    
    Specified by:
    
    supportsNotNullConstraintNames in interface Database
    
    Returns:
    
    true if the database supports naming NOT NULL constraints, false if not.
