任何幫助我請

Answer 1

一般來說，當您執行一個選擇，將多個表連接在一起，並至少有一列具有相同的納姆，你會得到一個「模棱兩可的列名」錯誤e，然後您引用該列而不用在表中添加前綴。

所以我你的情況我會假設customervendorname柱出現在多個表（也許CustomerVendorDetails和CustomerVendorAddressDetails？），所以當你在WHERE子句中使用它，你將需要使用表名前綴它。事實上，我已經看到你已經在要選擇的列的列表中做了這個;你只需要在整個陳述中做同樣的事情。

因此

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

需要變得

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

和可能的其他約束類似的變化。

Answer 2

的問題必須在這一部分：

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

你應該檢查，如果你在你的CustomerVendorAddressDetails和ContactPersonDetails表customervendorid和customervendorname列

Answer 3

（@customervendorid爲空或customervendorid像@customervendorid）或（@customervendorname爲空或客戶名稱爲@customervendorname）

檢查這兩條線..

請發佈您的客戶和您正在使用的其他表的結構。這將很容易猜到錯誤

Answer 4

CustomerVendorDetails.customervendorid和customerVendorname替換customervendorid由CustomerVendorAddressDetails.customervendname在哪裏條件將工作。
