Method Detail

start

public void start()
           throws TranslatorException

Overrides:

start in class JDBCExecutionFactory

Throws:

TranslatorException

getSQLConversionVisitor

public SQLConversionVisitor getSQLConversionVisitor()

Description copied from class: JDBCExecutionFactory

Create the SQLConversionVisitor that will perform translation. Typical custom JDBC connectors will not need to create custom conversion visitors, rather implementors should override existing JDBCExecutionFactory methods.

Overrides:

getSQLConversionVisitor in class JDBCExecutionFactory

Returns:

the SQLConversionVisitor

getSupportedFunctions

public List<String> getSupportedFunctions()

Overrides:

getSupportedFunctions in class JDBCExecutionFactory

translateLiteralDate

public String translateLiteralDate(Date dateValue)

Description copied from class: JDBCExecutionFactory

Subclasses should override this method to provide a different sql translation of the literal date value. By default, a date literal is represented as: {d '2002-12-31'}

Overrides:

translateLiteralDate in class JDBCExecutionFactory

Parameters:

dateValue - Date value, never null

Returns:

Translated string

translateLiteralTime

public String translateLiteralTime(Time timeValue)

Description copied from class: JDBCExecutionFactory

Subclasses should override this method to provide a different sql translation of the literal time value. By default, a time literal is represented as: {t '23:59:59'} See JDBCExecutionFactory.hasTimeType() to represent literal times as timestamps.

Overrides:

translateLiteralTime in class JDBCExecutionFactory

Parameters:

timeValue - Time value, never null

Returns:

Translated string

translateLiteralTimestamp

public String translateLiteralTimestamp(Timestamp timestampValue)

Description copied from class: JDBCExecutionFactory

Subclasses should override this method to provide a different sql translation of the literal timestamp value. By default, a timestamp literal is represented as: {ts '2002-12-31 23:59:59'}. See JDBCExecutionFactory.getTimestampNanoPrecision() to control the literal precision.

Overrides:

translateLiteralTimestamp in class JDBCExecutionFactory

Parameters:

timestampValue - Timestamp value, never null

Returns:

Translated string

supportsScalarSubqueries

public boolean supportsScalarSubqueries()

Overrides:

supportsScalarSubqueries in class JDBCExecutionFactory

public boolean supportsUnions()

Overrides:

supportsUnions in class JDBCExecutionFactory

supportsIntersect

public boolean supportsIntersect()

Overrides:

supportsIntersect in class ExecutionFactory<DataSource,Connection>

Overrides:

supportsExcept in class ExecutionFactory<DataSource,Connection>

supportsInlineViews

public boolean supportsInlineViews()

Overrides:

supportsInlineViews in class JDBCExecutionFactory

supportsAggregatesEnhancedNumeric

public boolean supportsAggregatesEnhancedNumeric()

Overrides:

supportsAggregatesEnhancedNumeric in class ExecutionFactory<DataSource,Connection>

supportsCommonTableExpressions

public boolean supportsCommonTableExpressions()

Overrides:

supportsCommonTableExpressions in class ExecutionFactory<DataSource,Connection>

getDefaultNullOrder

public ExecutionFactory.NullOrder getDefaultNullOrder()

Overrides:

getDefaultNullOrder in class JDBCExecutionFactory

translateCommand

public List<?> translateCommand(Command command,
                                ExecutionContext context)

Description copied from class: JDBCExecutionFactory

Overrides:

translateCommand in class JDBCExecutionFactory

Returns:

a list of translated parts

usesDatabaseVersion

protected boolean usesDatabaseVersion()

Overrides:

usesDatabaseVersion in class JDBCExecutionFactory

getHibernateDialectClassName

public String getHibernateDialectClassName()

Overrides:

getHibernateDialectClassName in class JDBCExecutionFactory

supportsBooleanExpressions

protected boolean supportsBooleanExpressions()

Description copied from class: JDBCExecutionFactory

if boolean expressions are directly supported. will generally be false if there is no boolean datatype

Overrides:

supportsBooleanExpressions in class JDBCExecutionFactory

Returns:
