使用联接更新Informix表 [英] update Informix table with joins

问题描述

这是Informix更新的正确语法吗?

Is this the correct syntax for an Informix update?

update table1
set table1.code = 100
from table1 a, table2 b, table3 c
where a.key = c.key
a.no = b.no
a.key = c.key
a.code = 10
b.tor = 'THE'
a.group = 4183
a.no in ('1111','1331','1345')

我收到通用的-201'发生语法错误'消息，但看不到出了什么问题.

I get the generic -201 'A syntax error has occurred' message, but I can't see what's wrong.

推荐答案

您的语法错误是table1.code

your syntax error is table1.code

set table1.code = 100

将其更改为

set a.code = 100

完整代码

update table1
set a.code = 100
from table1 a, table2 b, table3 c
where a.key = c.key
and a.no = b.no
and a.key = c.key
and a.code = 10
and b.tor = 'THE'
and a.group = 4183
and a.no in ('1111','1331','1345')
