なぜこれが機能しないのですか?
DECLARE @temp table
(ShipNo int,
Supplier varchar(10)
)
INSERT INTO @temp VALUES (1,'CFA')
INSERT INTO @temp VALUES (1, 'TFA')
INSERT INTO @temp VALUES (2, 'LRA')
INSERT INTO @temp VALUES (2, 'LRB')
INSERT INTO @temp VALUES (3, 'ABC')
INSERT INTO @temp VALUES (4, 'TFA')
Declare @OrderBy varchar(255)
sET @OrderBy = 'Supplier'
SELECT ROW_NUMBER() OVER (ORDER BY
CASE @OrderBy
WHEN 'Supplier' THEN Supplier
WHEN 'ShipNo' THEN ShipNo
END
) AS RowNo,
ShipNo,
Supplier
FROM @temp
しかし、CaseステートメントでShipNoをvarcharにキャストすると、機能しますか?
