ケースIF THENステートメントを含める方法SQL

Question

以下のストアドプロシージャでcaseステートメントを作成しようとしています。私は@OHDeptは、次の操作を実行したい：

部門= 15場合は、そのような指定された非ブール型の式」として、私が試した16

すべては私にエラーのいくつかの種類を与える示して条件は、近く「他」が期待されるコンテストで。

私は私が何か間違ったことをやっている知っているが、私はよく分からない。誰も私を助けてくださいことはできますか？ ありがとう！

Answer 1

投稿コードのどこには表示されません@OHDeptには任意の値が割り当てられます。

それは値が割り当てられている場合はいつでも、あなたはこのようなもので、そのステートメントに従うことができます：

set @OHDept = case when @OHDept = '15' then '16' else @OHDept end; 

Answer 2

あなたはAにifをどうしたいのと同様の方法でcaseを使用しようとしているように見えます手続き型言語。 SQL caseでは、の値がではなく、フロー内のブランチに評価される式です。

そのまま1516に残し、他の値を変換式は次のとおりです。

case where @OHDept = '15' then '16' else @OhDept end 

あなたはそれを示す言及したので、その式がselect句に属するようですね。

また、ブール論理があなたを引き上げていると思います。このようにして、クエリの先頭に多くのものを簡単に集約することができます。 andの優先順位がorより高いため、厳密にかっこは必要ありません。

(
    @Status in ('O', 'S') and ContractStatus in (1, 2, 3)) 
    and MonthClosed > @ThroughMth 
) 
or 
(
    @Status = 'C' and ContractStatus = 3 
    and MonthClosed between @BegMthClosed and @EndMthClosed 
) 
or 
(
    @Status = 'A' and ContractStatus <> 0 
)
