entity.getKey( )
entity.getKey( )
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.
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))
