Set of Values Generation

Set of Values Generation

A set of values generation rule is a global or ad hoc rule that writes a small data set to the target table. You can list the data values that you want to write to the table when you create a set of values generation rule.
You can use the string, numeric, and date data types in a set of values generation rule. You add data values in the rule and specify what percent of the rows in the target table you want to have the value. You can enter the percent in decimal values. You can use set of values generation for columns that have a small number of values, such as membership status.
Set of values rules can be global rules or ad hoc rules.
The following image shows the set of values parameters:
The set of values parameters are value, distribution percent, null values, and invalid values.

Set of Values Generation Example

You want to generate payment information. The target database has a PAYMENT_TYPE column with Visa, MasterCard, and Paypal values. You want 60% of the rows to have the Visa value, 30% of the rows to have the MasterCard value, and 10% of the rows to have the Paypal value.
You create a set of values rule with the string data type. You add Visa in the value field and enter 60 in the distribution percent field. You click the add button twice to add two additional values to the rule. In the second row, you enter MasterCard in the value field and 30 in the distribution percent field. In the third row, you enter Paypal in the value field and 10 in the distribution field.
