Joins

Restriction: This topic applies to Windows environments only.

A join is a form of query that occurs any time more than one table or view name appears in the FROM clause of a query statement -- resulting in column data being retrieved from each table. The XDB Server allows up to 10 table names to appear within each level of a query.
