SybaseIQExecutionFactory

public SybaseIQExecutionFactory()

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

getSupportedFunctions

public List<String> getSupportedFunctions()

Description copied from class: ExecutionFactory

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

Overrides:

getSupportedFunctions in class JDBCExecutionFactory

See Also:

for a listing of system pushdown functions. Note that not all system functions are listed as some functions will use a common name such as CONCAT vs. the || operator, and other functions will be rewritten and not pushed down, such as SPACE.
Note: User defined functions should be specified fully qualified.

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

supportsFunctionsInGroupBy

public boolean supportsFunctionsInGroupBy()

Description copied from class: ExecutionFactory

Support indicates that the connector supports non-column expressions in GROUP BY, such as: SELECT dayofmonth(theDate), COUNT(*) FROM table GROUP BY dayofmonth(theDate)

Overrides:

supportsFunctionsInGroupBy in class ExecutionFactory<DataSource,Connection>

getMaxFromGroups

public int getMaxFromGroups()

Description copied from class: ExecutionFactory

The number of groups supported in the from clause. Added for a Sybase limitation.

Overrides:

getMaxFromGroups in class ExecutionFactory<DataSource,Connection>

Returns:

the number of groups supported in the from clause, or -1 if there is no limit

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<DataSource,Connection>

booleanNullable

public boolean booleanNullable()

Overrides:

booleanNullable in class BaseSybaseExecutionFactory

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

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

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<DataSource,Connection>

usesDatabaseVersion

protected boolean usesDatabaseVersion()

Overrides:

usesDatabaseVersion in class JDBCExecutionFactory

supportsSelectWithoutFrom

public boolean supportsSelectWithoutFrom()

Overrides:

supportsSelectWithoutFrom in class ExecutionFactory<DataSource,Connection>

Returns:
