Defining a primary key

You must specify one or more columns to use as the primary key. This allows for more efficient loading and updating of the personalization data from the Custom Table into memory.

To define a primary key:

1. Select fields in the Available Fields list and use the right arrow to move them to the Primary Key Fields list.

   Use the left arrow to remove fields from the list.

   To reorder primary key fields, select a field and use the up and down arrows to move it into a different position. Use the double arrows to move a field to the top or bottom of the list.

2. Click Next to create the data source.
