How To Define a Variable to Match a Table Column Data Type?
Submitted by: AdministratorIf you have a table, and want to define some variables to have exactly the same data types as some columns in that table, you can use table_name.column_name%TYPE as data types to define those variables. The tutorial sample below shows you how to do this:
CREATE OR REPLACE PROCEDURE ggl_CENTER AS
my_email employees.email%TYPE;
my_salary employees.salary%TYPE;
BEGIN
SELECT email, salary INTO my_email, my_salary
FROM employees WHERE employee_id = 101;
DBMS_OUTPUT.PUT_LINE('My email = ' || my_email);
DBMS_OUTPUT.PUT_LINE('My salary = ' || my_salary);
END;
/
My email = NKOCHHAR
My salary = 17000
