关于mysql触发器问题
表（testT）定义：
id int
version int
name string
建立触发器，更新时自动算出最大的version，并赋值给当前修改行的version字段。
下面写法不对，求修改以及其他简单写法
create trigger t_updateVersion
before update on testT
for each row
begin
declare aaa INT; /*出错：sql syntax error near INT*/
select aaa= max(version) from testT;
set new.version = aaa + 1;
end /*出错：sql syntax error near INT*/
-
SQL code
delimiter // create trigger t_updateVersion before update on testT for each row begin declare aaa int; select max(version) into aaa from testT; set new.version = aaa + 1; end;//
探讨
SQL code
delimiter //
create trigger t_updateVersion
before update on testT
for each row
begin
declare aaa int;
select max(version) into aaa from testT;
set new.version = aaa + 1;
end;//
