An administrator can deny access to columns in a virtual table of an SQL data object. The administrator can configure the Data Integration Service behavior for queries against a restricted column.
The following results might occur when the user queries a column that the user does not have permissions for:
The query returns a substitute value instead of the data. The query returns a substitute value in each row that it returns. The substitute value replaces the column value through the query. If the query includes filters or joins, the results substitute appears in the results.
The query fails with an insufficient permission error.
