使用当前月份名称将SSIS中的日期转换为字符串？

Question

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'

我怎样才能改变它，使我的 @ToDate 成为 01-may-2018 而不是 01-maj-2018？

我试着搜索了一下，有很多类似的问题，但没有一个关于这个特定错误的问题。为什么它甚至让我的字符串有 maj?

Answer 1

不知道具体错误，但我认为这可能是由于 SQL 服务器排序规则造成的，请尝试检查您的服务器排序规则。或者可能正在探索排序规则可能对您有所帮助。

Answer 2

您的包裹的 LocaleID 似乎不同于 1033（美国英语）。

这个值可以在包级别进行调整，因此所有底层任务都将继承它。

如果值是在 SQL 服务器端生成的

，也可能与 SQL 服务器登录的语言设置有关

Answer 3

我同意@AlexanderVolok，看起来包裹的 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，否则您在将日期转换为字符串的数据流任务之前添加一个 Expression Task使用条件运算符 ? : 的不同格式，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)

那么你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)
