如何將nvarchar轉換為int然后在sql server中添加

Question

我不明白這個查詢有什么問題

select cast(B1 as int)+
       (cast(H1 as int)+
       (cast(C1 as int)+
       (cast(I1 as int)) as [man]

在數據庫中將B1, H1, C1, I1聲明為nvarchar

error: Incorrect syntax near the keyword 'as'.

Answer 1

您缺少結尾括號。

select (cast(B1 as int)+cast(H1 as int)+cast(C1 as int)+cast(I1 as int)) as [man]

Answer 2

缺少括號...寫為：

select cast(B1 as int)+
       (cast(H1 as int))+
       (cast(C1 as int))+
       (cast(I1 as int)) as [man]
