Constructor Detail

IngresExecutionFactory

public IngresExecutionFactory()

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.

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<DataSource,Connection>

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:

translateLimit in class JDBCExecutionFactory

Returns:

a list of translated parts

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

getDefaultNullOrder

public ExecutionFactory.NullOrder getDefaultNullOrder()

Description copied from class: ExecutionFactory

Returns the default null ordering

Overrides:

getDefaultNullOrder in class JDBCExecutionFactory

Returns:

the ExecutionFactory.NullOrder

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
