Abstract
Returning rows having column values masked is disclosed. In response to receiving a database command, a modified database command is created that specifies whether to mask a value by returning a mask of the value instead of the value. In an embodiment, the condition expression is included in a policy function that is referenced by a policy. In an embodiment, the policy determines how the condition expressions are used. The condition expression may be used to determine which column values to mask. The condition expression may also be used to filter which rows are returned.
