DROP ROW LEVEL SECURITY POLICY

Function

DROP ROW LEVEL SECURITY POLICY deletes a row-level access control policy from a table.

Precautions

Only the owner of a table or a system administrator has the DROP ROW LEVEL SECURITY POLICY permission.

Syntax

1

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

Parameter Description

• IF EXISTS

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

• policy_name
  Specifies the name of a row-level access control policy to be deleted.

  • table_name

    Specifies the name of the table containing the row-level access control policy.

  • CASCADE/RESTRICT

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