Synopsis​

DROP RULE [IF EXISTS] <name> ON <table_name> [CASCADE | RESTRICT]

Description​

DROP RULE drops a rewrite rule from a table or view.

Parameters​

IF EXISTS

Do not throw an error if the rule does not exist. Apache Cloudberry issues a notice in this case.

name

The name of the rule to remove.

table_name

The name (optionally schema-qualified) of the table or view that the rule applies to.

CASCADE

Automatically drop objects that depend on the rule, and in turn all objects that depend on those objects.

RESTRICT

Examples​

Remove the rewrite rule sales_2006 on the table sales:

DROP RULE sales_2006 ON sales;
