translateLimit

public List<?> translateLimit(Limit limit,
                              ExecutionContext context)

Description copied from class: JDBCExecutionFactory

Return a List of translated parts (LanguageObjects and Objects), or null if to rely on the default translation.

Overrides:

Returns:

a list of translated parts

useSelectLimit

public boolean useSelectLimit()

Description copied from class: JDBCExecutionFactory

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
