Public Member Functions | |
| clearIndex () | |
| clears any index base for the constraint | |
| constructor (string n, string n_src) | |
| creates the object and sets its name and the check clause source | |
| bool | setIndexBase (string ix) |
| returns True if the object supports an index property and is set, False if not | |
Public Member Functions inherited from SqlUtil::AbstractConstraint | |
| abstract | clearIndex () |
| clears any index base for the constraint | |
| constructor (string n) | |
| creates the object and sets its name | |
| bool | equal (AbstractConstraint c) |
| returns True if the argument is equal to the current object, False if not | |
| abstract string | getCreateSql (string table_name, *hash< auto > opt) |
| returns a string that can be used to create the constraint in the database | |
| string | getDisableSql (string table_name) |

| abstract list< auto > | getRenameSql (string table_name, string new_name) |
| returns a list of SQL strings that can be used to rename the constraint in the database | |
| bool | hasColumn (string cname) |
| returns True if the constraint references the named column | |
| rename (string n) | |
| renames the constraint | |
| abstract bool | setIndexBase (string ix) |
| returns True if the object supports an index property and is set, False if not | |
