The Metadata Matcher uses the specified column name to apply masking rules to the result set of a Microsoft SQL Server stored procedure call.
Use the Metadata Matcher to match column names in the result set of a Microsoft SQL Server stored procedure, in order to mask the result set. You can also use the Metadata Matcher to match the XPath in the XML content of a column in the result set of a Microsoft SQL Server stored procedure call.
To mask the result set of a Microsoft SQL Server procedure call, use the Metadata Matcher in addition to the Procedure Call matcher. For more information, see the chapter "Stored Procedure Result Set Masking."
