报错：无法绑定由多个部分组成的标识符

Question

既然你的select 语句没有 from lwmain2，
那么你的where中的lwmain2 从哪里来的？

Answer 1

两个表的表结构是一样的，就是想把一个表里面的数据导入到另外一个表，条件是一个表的nh<>另外一个表的nh,报错为无法绑定由多个部分组成的标识符 "lwmain2.dbo.LWnhdd.nh",是因为什么呢？

Answer 2

试试：INSERT  INTO [lwmain2].dbo.LWnhdd
        ( nh ,
          dd ,
          azwz ,
          x ,
          y ,
          dwz ,
          bm ,
          sblb
        )
        SELECT  nh ,
                dd ,
                azwz ,
                x ,
                y ,
                dwz ,
                bm ,
                sblb
        FROM    [lwmain1].dbo.LWnhdd
        WHERE   [lwmain1].dbo.LWnhdd.nh <> [lwmain2].dbo.LWnhdd.nh

Answer 3

insert into lwmain2.dbo.LWnhdd(nh,dd,azwz,x,y,dwz,bm,sblb)
select lwmain1.dbo.LWnhdd.nh,lwmain1.dbo.LWnhdd.dd,lwmain1.dbo.LWnhdd.azwz,lwmain1.dbo.LWnhdd.x,lwmain1.dbo.LWnhdd.y,lwmain1.dbo.LWnhdd.dwz,lwmain1.dbo.LWnhdd.bm,lwmain1.dbo.LWnhdd.sblb from lwmain1.dbo.LWnhdd 
where  lwmain1.dbo.LWnhdd.nh<>lwmain2.dbo.LWnhdd.nh

Answer 4

那你告诉我从lwmain2中获取数据插入到lwmain1表中代码应该怎么写呢？条件是lwmain1.dbo.LWnhdd.nh<>lwmain2.dbo.LWnhdd.nh

Answer 5

举例：Insert Into 表3(a,b,c,d,e,f)
select 表1.a,表1.b,表1.c,表2.d,表2.e,表2.f 
from 表1 join 表2 on 表1.a=表2.c
where 表1.b<>表2.e

Answer 6

还是报无法绑定由多个部分组成的标识符 "lwmain2.dbo.LWnhdd.nh"。  这个错误啊，哪里的问题啊

Answer 7

晕，看到问题了，抛开insert，你的select少了表关联

Answer 8

INSERT  INTO [lwmain2].dbo.LWnhdd
        ( nh ,
          dd ,
          azwz ,
          x ,
          y ,
          dwz ,
          bm ,
          sblb
        )
        SELECT  nh ,
                dd ,
                azwz ,
                x ,
                y ,
                dwz ,
                bm ,
                sblb
        FROM    [lwmain1].dbo.LWnhdd
        WHERE   [lwmain1].dbo.LWnhdd.nh NOT IN (SELECT  [lwmain2].dbo.LWnhdd.nh FROM [lwmain2].dbo.LWnhdd)

Answer 9

---这样写
insert into lwmain2.dbo.LWnhdd(nh,dd,azwz,x,y,dwz,bm,sblb)
select nh,dd,azwz,x,y,dwz,bm,sblb from lwmain1.dbo.LWnhdd 
where  lwmain1.dbo.LWnhdd.nh not in(select nh from lwmain2.dbo.LWnhdd.nh)
