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. Cloudberry Database 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
Refuse to drop the rule if any objects depend on it. This is the default.
Examples
Remove the rewrite rule sales_2006 on the table sales:
DROP RULE sales_2006 ON sales;
Compatibility
