H2ExecutionFactory

public H2ExecutionFactory()

Method Detail

start

public void start()
           throws TranslatorException

Description copied from class: ExecutionFactory

Initialize the connector with supplied configuration

Overrides:

start in class JDBCExecutionFactory

Throws:

TranslatorException

translateLiteralDate

public java.lang.String translateLiteralDate(java.sql.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 java.lang.String translateLiteralTime(java.sql.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 java.lang.String translateLiteralTimestamp(java.sql.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

getSupportedFunctions

public java.util.List<java.lang.String> getSupportedFunctions()

Description copied from class: ExecutionFactory

Get list of all supported function names. Arithmetic functions have names like "+".

Overrides:

getSupportedFunctions in class JDBCExecutionFactory

supportsInlineViews

public boolean supportsInlineViews()

Description copied from class: ExecutionFactory

Support indicates connector can accept inline views (subqueries in the FROM clause).

Overrides:

supportsInlineViews in class JDBCExecutionFactory

supportsRowLimit

public boolean supportsRowLimit()

Description copied from class: ExecutionFactory

Gets whether the connector can limit the number of rows returned by a query.

Overrides:

supportsRowLimit in class ExecutionFactory<javax.sql.DataSource,java.sql.Connection>

supportsRowOffset

public boolean supportsRowOffset()

Description copied from class: ExecutionFactory

Gets whether the connector supports a SQL clause (similar to the LIMIT with an offset) that can return result sets that start in the middle of the resulting rows returned by a query

Overrides:

supportsRowOffset in class ExecutionFactory<javax.sql.DataSource,java.sql.Connection>

supportsExcept

public boolean supportsExcept()

Description copied from class: ExecutionFactory

Support indicates that the connector supports the EXCEPT of two queries.

Overrides:

supportsExcept in class ExecutionFactory<javax.sql.DataSource,java.sql.Connection>

supportsIntersect

public boolean supportsIntersect()

Description copied from class: ExecutionFactory

Support indicates that the connector supports the INTERSECT of two queries.

Overrides:

supportsIntersect in class ExecutionFactory<javax.sql.DataSource,java.sql.Connection>

supportsAggregatesEnhancedNumeric

public boolean supportsAggregatesEnhancedNumeric()

Description copied from class: ExecutionFactory

Support indicates connector can accept STDDEV_POP, STDDEV_VAR, VAR_POP, VAR_SAMP

Overrides:

supportsAggregatesEnhancedNumeric in class ExecutionFactory<javax.sql.DataSource,java.sql.Connection>
