前端之家收集整理的这篇文章主要介绍了
sql – 使用连接更新Informix表，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
这是Informix更新的正确语法吗？
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')
我得到通用的-201’发生语法错误’消息,但我看不出有什么问题.
你的语法
错误是table1.code
set table1.code = 100
将此更改为
set a.code = 100
完整代码
update table1
set a.code = 100
from table1 a,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','1345')
