存储过程MySQL的句法

Question

请帮我解决这个存储过程做了错误：

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 

它显示了一个语法错误：

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(

请帮我修正这个错误。谢谢

Answer 1

语法无误。它适用于新的MySQL服务器。

您可能会使用旧的MySQL服务器，其中CHARSET子句不支持字符串参数。检查服务器版本的语法。
