Question

尝试以下SQL代码时出现以下错误

SELECT
    g.WeekNumber as [Week], f.FranchiseName as Opponent, 
    CAST(CASE WHEN g.Home = 1 THEN 'Home' ELSE 'Away' END) AS HomeAway,
    g.PointsFor, g.PointAgainst, 
    CAST(CASE WHEN g.Won = 1 THEN 'Win' ELSE 'Loss' END) AS Result
FROM
    dbo.Game g
LEFT JOIN dbo.Franchise f ON g.OpponentID = f.FranchiseID

产生的错误是Incorrect syntax near 'CAST', expected 'AS'.

我在做If /那么错吗？我想将bit列转换为＆＃34;是＆＃34;或＆＃34;否＆＃34;在我看来

Answer 1

CAST用于将表达式从一种数据类型转换为另一种数据类型。您的查询中不需要CAST，如果您正在使用它，那么它应该是这样的：

CAST(CASE WHEN g.Home = 1 THEN 'Home' ELSE 'Away' END AS VARCHAR(5)) AS HomeAway

期待＆＃39; AS＆＃39;在Cast If Then
