DROP OPERATOR FAMILY
DROP OPERATOR FAMILY
DROP OPERATOR FAMILY - remove an operator family
Synopsis
DROP OPERATOR FAMILY [ IF EXISTS ]nameUSINGindex_method[ CASCADE | RESTRICT ]
Description
DROP OPERATOR FAMILY
drops an existing operator family.
To execute this command you must be the owner of the operator family.
DROP OPERATOR FAMILY
includes dropping any operator
classes contained in the family, but it does not drop any of the operators
or functions referenced by the family. If there are any indexes depending
on operator classes within the family, you will need to specify
CASCADE
for the drop to complete.
Parameters
-
IF EXISTS -
Do not throw an error if the operator family does not exist. A notice is issued in this case.
-
name -
The name (optionally schema-qualified) of an existing operator family.
-
index_method -
The name of the index access method the operator family is for.
-
CASCADE -
Automatically drop objects that depend on the operator family, and in turn all objects that depend on those objects (see Section 5.15 ).
-
RESTRICT -
Refuse to drop the operator family if any objects depend on it. This is the default.
Examples
Remove the B-tree operator family
float_ops
:
DROP OPERATOR FAMILY float_ops USING btree;
This command will not succeed if there are any existing indexes
that use operator classes within the family. Add
CASCADE
to
drop such indexes along with the operator family.
Compatibility
There is no
DROP OPERATOR FAMILY
statement in the
SQL standard.
