If you now want to create a query that returns all articles that a customer has ordered, you must retrieve data from two spreadsheets. To do this, you must tell $[officename] what the relationship exists between the data in the two spreadsheets.</paragraph>

When you release the mouse button, a line connecting the two fields in the two windows appears. The corresponding condition that the content of the two field names must be identical is entered in the resulting SQL query.</paragraph>
