20. 2. 1. Working with Variables


Every variable that you use must be declared, together with its datatype, in a DECLARE statement.



You can declare more than one variable at a time in a single DECLARE as long as you separate the variables with commas.



Syntax for the DECLARE Statement

DECLARE

 {@local_variable [AS] data_type}
