Mysql IN查询过长报错解决

Mysql IN查询过长报错解决

mysql 5.7
程序中需要大批量使用update in，in语句当条件大于1000条时就会报错

sql处理

delete from table_name where exists(select t.id table_name t where state="xxx"); 
update table_name set state="xxx" where exists( select t.id table_name t where state="xxx" ); 
以上代码等同于 
update table_name set state="xxx" where id in( select t.id table_name t where state="xxx");
