任何帮助我请

Answer 1

一般来说，当您执行一个选择，将多个表连接在一起，并至少有一列具有相同的纳姆，你会得到一个“模棱两可的列名”错误e，然后您引用该列而不用在表中添加前缀。

所以我你的情况我会假设customervendorname柱出现在多个表（也许CustomerVendorDetails和CustomerVendorAddressDetails？），所以当你在WHERE子句中使用它，你将需要使用表名前缀它。事实上，我已经看到你已经在要选择的列的列表中做了这个;你只需要在整个陈述中做同样的事情。

因此

WHERE (@customervendortype is null or 
     customervendortype like @customervendortype) 

需要变得

WHERE (@customervendortype is null or 
     CustomerVendorAddressDetails.customervendortype like @customervendortype) 

和可能的其他约束类似的变化。

Answer 2

的问题必须在这一部分：

or (@customervendorid is null or customervendorid like @customervendorid) 
     or (@customervendorname is null or customervendorname like @customervendorname) 

你应该检查，如果你在你的CustomerVendorAddressDetails和ContactPersonDetails表customervendorid和customervendorname列

Answer 3

（@customervendorid为空或customervendorid像@customervendorid）或（@customervendorname为空或客户名称为@customervendorname）

检查这两条线..

请发布您的客户和您正在使用的其他表的结构。这将很容易猜到错误

Answer 4

CustomerVendorDetails.customervendorid和customerVendorname替换customervendorid由CustomerVendorAddressDetails.customervendname在哪里条件将工作。
