Data Profiler Global Variables

You can define global variables for the fields used in the Data Profiler rules so you do not need to use the qualified field name for each field. When defining variables, the qualified field name syntax is used. For more information about qualified field names, see Master Index Field Notations in Understanding Sun Master Index Configuration Options . Variables are defined in the varList element of the profiling rules section, and each variable is defined by a var element.

The var element has these attributes:

• name – The name of the variable.

• default – The qualified field name to the field defined by the name attribute.

Here is an example of a variable list for a master index application storing person data.

<varList>
   <var name="fname" default="Person.FirstName"/>
   <var name="lname" default="Person.LastName"/>
   <var name="ssn" default="Person.SSN"/>
   <var name="zip" default="Person.Address.PostCode"/>
   <var name="state" default="Person.Address.State"/>
</varList>

When you reference a variable in a rule, use the format “:[variable_name]” (where variable_name is the name you assigned to the variable). For example, to reference the FirstName field as defined above, it would look similar to this in the rules:

<field fieldName=":[fname]"/>
