You can use the Replace Table action to change the FROM clause of the original SQL statement to provide row-level security. You can replace the table reference with a table reference or subquery that you define in the Alternative Object or Query field.

The Alternative Object or Query filed can contain global symbols or the Replace Table rule action symbols. You can define global symbols in other security rules that you wan to use in the Replace Table rule action.

The Replace Table rule action symbols relate to the current SQL statement FROM clause. Use the \(prefix), \(tableOnly), and \(table) symbols to specify that you want to preserve the table name, preserve the path, or replace the path and the table name.

The following table describes the Replace Table action parameters:

Parameter	Description
Table Name	A regular expression that represents the database object names that you want to replace.
Alternative Object or Query	The object name or query that you want to replace the original table name.
