DROP ROW LEVEL SECURITY POLICY

Description

Drops a row-level security policy from a table.

Precautions

Only the table owner or administrators can drop a row-level security policy from the table.

Syntax

1

DROP [ ROW LEVEL SECURITY ] POLICY [ IF EXISTS ] policy_name ON table_name [ CASCADE | RESTRICT ]

Parameters

• IF EXISTS

  Reports a notice instead of an error if the specified row-level security policy does not exist.

• policy_name

  Specifies the name of the row-level security policy to be dropped.

• table_name

  Specifies the name of the table containing the row-level security policy.

• CASCADE | RESTRICT

  Currently, no objects depend on row-level security policies. Therefore, CASCADE is equivalent to RESTRICT, and they are reserved to ensure backward compatibility.
