gaodaima.com正常写法:
select * from table_name t where t.field1 in (1,2,3,4,…);
当在写存储过程in里面的列表用个传入参数代入的时候,就需要用到如下方式:
主要用到find_in_set函数
select * from table_name t where find_in_set(t.field1,’1,2,3,4′);
当然还可以比较笨实的方法,就是组装字符串,然后执行:
DROP PROCEDURE IF EXISTS photography.Proc_Test;
CREATE PROCEDURE photography.`Proc_Test`(param1 varchar(1000))
BEGIN
set @id = param1;
set @sel = ‘select * from access_record t where t.ID in (‘;
set @sel_2 = ‘)’;
set @sentence = concat(@sel,@id,@sel_2); — 连接字符串生成要执行的SQL语句
prepare stmt from @sentence; — 预编释一下。 “stmt”来&源gao@dai!ma.com搞$代^码%网预编释变量的名称,
execute stmt; — 执行SQL语句
deallocate prepare stmt; — 释放资源
END;
