Description

DROP COLLATION removes a previously defined collation. To be able to drop a collation, you must own the collation.

Parameters

    • Do not throw an error if the collation does not exist. A notice is issued in this case.
  • name

    • The name of the collation. The collation name can be schema-qualified.
  • CASCADE

    • Automatically drop objects that depend on the collation, and in turn all objects that depend on those objects (see Section 5.13).

    • Refuse to drop the collation if any objects depend on it. This is the default.

DROP COLLATION german;

Compatibility
