mysql stored function parameter syntax error

Question

What is wrong with this syntax?

mysql 5.5, phpmyadmin 3.4

delimiter ;;
create procedure foo(a text, b int, c text)
begin
select * from table_a where attribute1 like %a% 
and attribute2 = b
and attribute3 like %c%
end
;;

phpmyadmin tells me wrong syntax at line 1, but it doesn't seem to work, no matter what.

Answer 1

In your case you don't even need to change DELIMITER and use BEGIN ... END block. Your procedure might look like

CREATE PROCEDURE foo(a TEXT, b INT, c TEXT)
SELECT * 
  FROM table_a 
 WHERE attribute1 LIKE CONCAT('%', a, '%')
   AND attribute2 = b
   AND attribute3 LIKE CONCAT('%', c, '%');

Answer 2

Missing quotes.

delimiter ;;

create procedure foo(a text, b int, c text)
begin
  select * from table_a where attribute1 like concat('%', a,' %') 
  and attribute2 = b
  and attribute3 like concat('%', c,' %');
end;;
