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:

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
