Sample procedure in MySql with the use of a out parameter

Starting with the development of new operational data store, with integration of the portal.

The most handy feature is MySql procedure alongwith out parameters to pass the values on to a function or the front-end.

Example:

drop procedure rec_cnt;

delimiter //

create procedure rec_cnt(out param1 int)

begin

select count(*) into param1 from employee;

end//

delimiter ;

call rec_cnt(@param1);

select @param1;
