Method Detail

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.

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>

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>

supportsCommonTableExpressions

public boolean supportsCommonTableExpressions()

Overrides:

supportsCommonTableExpressions in class ExecutionFactory<DataSource,Connection>

Returns:

true if the WITH clause is supported

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>

supportsElementaryOlapOperations

public boolean supportsElementaryOlapOperations()

Overrides:

supportsElementaryOlapOperations in class ExecutionFactory<DataSource,Connection>

Returns:

true if Elementary OLAP operations are supported including window functions and inline window specifications that include simple expressions in partitioning and ordering

start

public void start()
           throws TranslatorException

Description copied from class: ExecutionFactory

Initialize the connector with supplied configuration

Overrides:

start in class BaseDB2ExecutionFactory

Throws:

TranslatorException

supportsArrayType

public boolean supportsArrayType()

Description copied from class: ExecutionFactory

The engine currently uses array types for dependent joins.

Overrides:

supportsArrayType in class ExecutionFactory<DataSource,Connection>

Returns:

true if an array type is supported.

getHibernateDialectClassName

public String getHibernateDialectClassName()

Overrides:

getHibernateDialectClassName in class JDBCExecutionFactory

getTemporaryTableName

public String getTemporaryTableName(String prefix)

Overrides:

getTemporaryTableName in class JDBCExecutionFactory

Returns:

a valid temporary table name

supportsGroupByRollup

public boolean supportsGroupByRollup()

Overrides:

supportsGroupByRollup in class ExecutionFactory<DataSource,Connection>

Returns:

true if the translator support GROUP BY ROLLUP
