无法绑定多部分标识符 sql
我在以下查询中得到 multipart can not be bound 错误
I get multipart can not be bound error on following query
update nfltx
set
b.boxno = a.boxno,
b.message = a.message,
b.nameboxno = a.nameboxno,
b.namemsg = a.namemsg,
b.phoneboxno = a.phoneboxno,
b.phonemsg = a.phonemsg
FROM ofltx a JOIN nfltx b
ON a.ls_fullnam = b.ls_fullnam
但是如果我从 boxno 消息中删除 b 并且所有我都不会收到错误消息.这背后的原因是什么.感谢您使用 sql server 2008
but if i remove b from boxno message and all i do not get the error . What is the reason behind this. Thank You using sql server 2008
推荐答案
在 FROM 子句中指定的表别名不能用作 SET column_name 中的限定符.这是无效的:
A table alias specified in a FROM clause cannot be used as a qualifier in SET column_name. This is not valid:
update nfltx
set
b.boxno = a.boxno,
b.message = a.message,
b.nameboxno = a.nameboxno,
b.namemsg = a.namemsg,
b.phoneboxno = a.phoneboxno,
b.phonemsg = a.phonemsg
FROM ofltx a JOIN nfltx b
ON a.ls_fullnam = b.ls_fullnam
要使其工作，请删除 b.列名的别名.
To make it work, remove the b. alias from the column name.
update nfltx
set
boxno = a.boxno,
message = a.message,
nameboxno = a.nameboxno,
namemsg = a.namemsg,
phoneboxno = a.phoneboxno,
phonemsg = a.phonemsg
FROM ofltx a JOIN nfltx b
ON a.ls_fullnam = b.ls_fullnam
