Constructor Detail

JRJdbcQueryExecuter

public JRJdbcQueryExecuter(JasperReportsContext jasperReportsContext,
                   JRDataset dataset,
                   Map<String,? extends JRValueParameter> parameters)

JRJdbcQueryExecuter

public JRJdbcQueryExecuter(JRDataset dataset,
                   Map<String,? extends JRValueParameter> parameters)

Deprecated. Replaced by JRJdbcQueryExecuter(JasperReportsContext, JRDataset, Map).

Method Detail

registerFunctions

protected void registerFunctions()

Registers built-in clause functions.

See Also:

registerFunctions(), JRAbstractQueryExecuter.appendClauseChunk(StringBuffer, String[])

getCanonicalQueryLanguage

protected String getCanonicalQueryLanguage()

Description copied from class: JRAbstractQueryExecuter

Returns a canonical query language for this query executer implementation.

The canonical language is used to retrieve extensions for the query executer.

The default implementation returns the runtime query language used in the dataset, but query executer implementations should override this method and return a fixed language.

Overrides:

getCanonicalQueryLanguage in class JRAbstractQueryExecuter

Returns:

a canonical query language

setTimeZone

protected void setTimeZone()

getParameterReplacement

protected String getParameterReplacement(String parameterName)

Description copied from class: JRAbstractQueryExecuter

Returns the replacement text for a query parameter.

Specified by:

getParameterReplacement in class JRAbstractQueryExecuter

Parameters:

parameterName - the parameter name

Returns:

the replacement text

Returns:

a JRDataSource wrapping the query execution result.

Throws:

JRException

close

public void close()

Description copied from interface: JRQueryExecuter
