The conditional expression that defines a relationship. The specific association between objects.

Any conditional expression

Remarks

Objects mentioned in the RelCondition should exist before the relationship is created. Referenced objects that do not exist when a RelCondition is created are interpreted as character strings if SET QUOTING is OFF.

For example,

defines a relationship between employees (in entity set Employees) and their departments (in entity set Departments) using a common department number (DeptNum).
