MySQL CASE の Tips?

Last updated at Posted at 2015-10-30

フィールド「M」 が1の時は昇順、1以外の時は降順にフィールドSSの内容で並べるという簡単な?
抽出クエリで、かなり苦労してしまった。 :weary:

select * from tbl1 ・ ORDER BY CASE WHEN M = 0 THEN SS ELSE SS DESC END,JJ --> NG!!

何で?? ELSE から END 間の記載が問題らしい。

結果は、シングルクオートで括ればOKだったんだ・・知らなかったぁ。 :open_mouth:

select * from tbl1 ・ ORDER BY CASE WHEN M = 1 THEN SS ELSE 'SS DESC' END,JJ -->OK!!
