generate. In this example, the clients file to be
produced will contain the following columns: ID,
First Name, Last Name,
Address, City which all are
defined as string data but the ID that is of integer type.
Some schema information don't necessarily need to be displayed. To hide
them away, click on Columns list button
next to the toolbar, and uncheck the relevant entries, such as Precision or Parameters.
Use the plus button to add as many columns to your schema
definition.
Click the Refresh button to preview the first generated row of your
output.
