Teradata Database executes the row-level security policy function you assign to the constraint object that corresponds to a table column to enforce the security policy for a data row. You can create a scalar function for each of the four request types (DELETE, INSERT, SELECT, UPDATE) that can be executed against the table on which the security constraint is defined.
