TSQL頂部1參數分配問題

Question

我試圖獲得一組郵編（具有特定上傳集中大多數條目的郵政編碼）的MODE平均值。我想使它成爲一個標量函數，而不是存儲過程。

爲什麼這項工作：

Select Top 1 LocationZip 
from UploadSetZipCodeCount 
where WorkOrderSet = 31 
Order by ZipCount desc 

但不是這樣的：

Select @setbasezip= Top 1 LocationZip 
from UploadSetZipCodeCount 
where WorkOrderSet = 31 
Order by ZipCount desc 

我的聲明類型用於LocationZip域是正確的。

Answer 1

只是語法問題... select top 1應該來賦值的變量前：

Select Top 1 @setbasezip = LocationZip 
from UploadSetZipCodeCount 
where WorkOrderSet = 31 
Order by ZipCount desc
