entity.getKey( )

Description

The entity.getKey( ) method returns the primary key value of the entity.

Primary keys can be numbers (longint) or strings. You can "force" the returned primary key value to be a string, no matter the actual primary key type, by passing the dk key as string option in the mode parameter.

Example

 C_OBJECT($employees;$employee)

 $employees:=ds.Employee.query("lastName=:1";"Smith")

 $employee:=$employees[0]

 ALERT("The primary key is "+$employee.getKey(dk key as string))
