2.2 Full Data Redaction to Redact All Data
Full data redaction redacts the entire contents of a specified column of a table or view.
By default the output is displayed as follows:
-
Character data types: The output is a single space.
-
Number data types: The output is a zero (
0
). -
Date-time data types: The output is set to the first day of January, 2001, which appears as
01-JAN-2001
.
When you run the DBMS_REDACT.ADD_POLICY
procedure, to set the function_type
parameter setting for full redaction, you enter the following setting:
function_type => DBMS_REDACT.FULL
Full redaction is the default and is used whenever a Data Redaction policy specifies the column but omits the function_type
parameter setting.
You can use the DBMS_REDACT.UPDATE_FULL_REDACTION_VALUES
procedure to change the full redaction output to different values. You can find the current values by querying the REDACTION_VALUES_FOR_TYPE_FULL
data dictionary view.
