Method Detail

start

public void start()
           throws TranslatorException

Description copied from class: ExecutionFactory

Initialize the connector with supplied configuration

Overrides:

start in class BaseDB2ExecutionFactory

Throws:

TranslatorException

addSourceComment

public boolean addSourceComment()

Description copied from class: JDBCExecutionFactory

Returns true to indicate that SQL should include a comment indicating the session and request ids.

Overrides:

addSourceComment in class JDBCExecutionFactory

supportsOrderByNullOrdering

public boolean supportsOrderByNullOrdering()

Description copied from class: ExecutionFactory

Returns whether the database supports explicit null ordering.

Overrides:

supportsOrderByNullOrdering in class ExecutionFactory<DataSource,Connection>

Returns:

true if nulls first/last can be specified

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.

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>

usesDatabaseVersion

protected boolean usesDatabaseVersion()

Overrides:

usesDatabaseVersion in class JDBCExecutionFactory

getHibernateDialectClassName

public String getHibernateDialectClassName()

Overrides:

getHibernateDialectClassName in class JDBCExecutionFactory

supportsGroupByRollup

public boolean supportsGroupByRollup()

Overrides:

supportsGroupByRollup in class ExecutionFactory<DataSource,Connection>

Returns:

true if the translator support GROUP BY ROLLUP

translate

public List<?> translate(LanguageObject obj,
                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. Override with care.

Overrides:

translate in class BaseDB2ExecutionFactory

Returns:

list of translated parts
