begin
        declare xx int ;
        set xx = index_of_page*15;

DELIMITER $$
CREATE PROCEDURE `filter`(in field varchar(40), in giatri varchar(40),in index_of_page int)
begin
        declare xx int ;
        set xx = index_of_page*15;

       set @query = CONCAT('SELECT * from test where field rlike ''', giatri,''' limit ',xx,',15;');

 PREPARE dynamic_statement FROM @query;
 EXECUTE dynamic_statement;
 DEALLOCATE PREPARE dynamic_statement;

DELIMITER ;


call `filter`('email','b',0);
