我收到错误，
Error converting data type varchar to date.
来自这个表达式
(DT_STR,30,1252)@[User::ToDate]
DO NET Source [40]: An error occurred executing the provided SQL command: "EXEC [dbo.StoredProcedure] @ToDate = '01-maj-2018'
Error: 0xC004706B at Import (See Expression!), SSIS.Pipeline: "ADO NET Source" failed validation and returned validation status "VS_ISBROKEN".
@ToDate = '01-maj-2018'
如何更改它，使我的 @ToDate 变为 01-may-2018 而不是 01-maj-2018？
我尝试搜索，有很多类似的问题，但没有一个关于此特定错误的问题。为什么它甚至让我的字符串有 maj？
最佳答案
我同意@AlexanderVolok，看起来该软件包的 LocalID 与英语不同，或者在操作系统区域设置中选择的日期时间文化信息不同。
(1) 使用条件 ? 更改月份名称:
如果您可以更改这些属性，那么它可能会解决问题，否则您可以在数据流任务之前添加一个表达式任务，该任务使用条件运算符将日期转换为不同格式的字符串？ :，例如(假设您正在处理波兰月份名称):
@[User::NewDataString] =
LEFT((DT_WSTR,50)@[User::ToDate],2) + "-" +
(SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "maj" ? "may" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "stycz" ? "Jan" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "lut" ? "feb" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "mar" ? "mar" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "maj" ? "may" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "czerw" ? "jun" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "lip" ? "jul" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "sierp" ? "aug" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "wrzes" ? "sep" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "pazdzier" ? "oct" :
SUBSTRING((DT_WSTR,50)@[User::ToDate], FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) + 1, FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",2) - FINDSTRING((DT_WSTR,50)@[User::ToDate],"-",1) - 1) == "listopad" ? "nov" : "dec" )
+ "-" + RIGHT((DT_WSTR,50)@[User::ToDate],4)
然后您应该将新变量作为参数传递。
(2) 将数据格式更改为 yyyy-MM-dd
您还可以使用表达式任务，将月份转换为数值，例如:
@[User::NewDateString] =
RIGHT((DT_WSTR,50)@[User::ToDate],4) + "-" +
RIGHT("0" + (DT_WSTR,50)DATEPART("mm", @[User::ToDate]),2) + "-" +
LEFT((DT_WSTR,50)@[User::ToDate],2)
