Question

DECLARE @Date DATE
DECLARE @FileName VARCHAR(1000)
DECLARE @FilePath VARCHAR(8000)

SET @FilePath = 'S:\FFgh\ENG\dataload'
SELECT @FileName = REVERSE(SUBSTRING(REVERSE(REPLACE@FilePath,'.DAT','')),1,CHARINDEX '\',REVERSE(REPLACE(@FilePath,'.DAT','')))-1))

SELECT @Date = CAST(Date AS DATE) FROM FileHeader Where FinalName = @FileName

SELECT CAST(@Date AS DATETIME) AS Date, @@ROWCOUNT AS HeaderFooter

这是我的代码，如果我使用文件名而不是@FileName它是有效的，否则会给我错误。

Answer 1

REPLACE和CHARINDEX找不到一些括号。在下面添加..

DECLARE @Date DATE
DECLARE @FileName VARCHAR(1000)
DECLARE @FilePath VARCHAR(8000)

SET @FilePath = 'S:\FFgh\ENG\dataload'
SELECT @FileName = REVERSE(SUBSTRING(REVERSE(REPLACE(@FilePath,'.DAT','')),1,CHARINDEX ('\',REVERSE(REPLACE(@FilePath,'.DAT','')))-1))

SELECT @Date = CAST(Date AS DATE) FROM FileHeader Where FinalName = @FileName

SELECT CAST(@Date AS DATETIME) AS Date, @@ROWCOUNT AS HeaderFooter

我收到此错误＆＃34;从字符串转换日期和/或时间时转换失败。＆＃34;
