PL/SQL Function Matcher

The PL/SQL Function matcher returns a match based on the PL/SQL function that you define and the parameters of the function.

When you use the PL/SQL Function matcher, you enter the name or the name and path of the function. You must include the path if the stored object is not in the client schema or catalog, depending on the database. On a DB2 database, you must include the path if the stored object is not in the path that is returned by the following statement from the Dynamic Data Masking administrator:

SELECT CURRENT_PATH FROM SYSIBM.SYSDUMMY1

Select the parameters that the function uses. The Rule Engine returns an error if you do not select the correct parameters for the function. You can view the rule.log file or use the Security Rule Set Simulator to verify that you selected the correct parameters.

When the Rule Engine applies the PL/SQL Function matcher, the PL/SQL function returns a

or a

. If the PL/SQL function returns

, a match occurs and the Rule Engine applies the rule action. If the PL/SQL function returns

, a match does not occur and the Rule Engine does not apply the rule action.

Informatica recommends that you create PL/SQL functions that have descriptive parameter names. If the parameter name describes the parameter value, the SQL script is comprehensible and easy to edit.

The PL/SQL Function matcher has the following properties:

Function Name: Enter the name and full path of the PL/SQL function. For example, you might enter
HR.dbo.get_employees
.
Include Database Username: Select if the function uses a database username parameter. The database username parameter defines the user for the session.
Include OS User: Select if the function uses an operating system user parameter. The operating system user parameter defines the user name for the user logged in to the operating system.
Include Client Host: Select if the function uses a client host parameter. The client host parameter defines the client host name or IP address.
Include Program Name: Select if the function uses a program name parameter. The program name defines the application or program name.
Include Statement: Select if the function uses a statement parameter. The statement parameter defines the SQL statement text. You must define the statement in VARCHAR.
Include Text Value: Select if the function uses a text value parameter.
Value to Use: Enter a text value parameter if you selected the Include Text Value property. You can use text or a global symbol to define the text value.
