boolean |
shouldPrintOutputTokenAtStart()
INTERNAL:
This is required in the construction of the stored procedures with output
parameters.
|
boolean |

boolean |
supportsGlobalTempTables()
INTERNAL: DB2 supports temp tables.
|
boolean |
supportsIdentity()
INTERNAL: Indicates whether the platform supports identity.
|
boolean |
supportsLockingQueriesWithMultipleTables()
