存储过程mysql语法

Question

Please help me to solve the mistake done in this stored procedure:

 CREATE DEFINER=`root`@`localhost` PROCEDURE `repos`(IN `order_condition` VARCHAR(100) CHARSET utf8, IN `from_date` VARCHAR(255) CHARSET utf8, IN `to_date` VARCHAR(255) CHARSET utf8, IN `dept_id` TINYINT(4), IN `type` VARCHAR(15) CHARSET utf8, IN `search_value` VARCHAR(50) CHARSET utf8, IN `institutionid` INT(11))
    NO SQL
BEGIN

set @strWhere   = "";
set @strWhere   = CONCAT(@strWhere,"t1.inst_id = ",instid);
set @selectstr  = '';
set @selectstr2 = '';
set @joinstr    = '';
set @joinstr2   = '';
set @group2= '';

set @selectstr = CONCAT(",t2.`std_name`");
set @selectstr2= CONCAT(",t5.`student_name`,t5.`roll_no`,t5.`student_id`");
set @joinstr = CONCAT("left join standard_master as t2 on t1.`std_id`= t2.`std_id` ");
set @joinstr2 = CONCAT("left join student_det as t5 on t1.`std_id`= t5.`std_id` ");
set @strWhere = CONCAT(@strWhere," AND t1.std_id = ",dept_id);
set @group2= CONCAT("t5.`student_id`");


SET @query = CONCAT("select t1.* ",@selectstr," , t3.term_name, SUM(t4.amount) as fee_amount",@selectstr2," FROM inst_fee AS t1 ",@joinstr," left join term_master as t3 on t1.term_id = t3.term_id left join inst_amtdet as t4 on t4.masterid = t1.masterid ",@joinstr2,"  WHERE ",@strWhere,  " AND ",@group2,  " NOT IN (select id from student_master) Group by t1.f_name  ", order_condition);

PREPARE stmt FROM @query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

#select @query;


END

It shows a syntax error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'IN(

Please help me to fix the error. Thanks

Answer 1

The syntax is correct. It works on new MySQL servers.

It is possible that you use old MySQL server, where CHARSET clause was not supported for string parameters. Check the syntax for your server version.
