使用当前月份名称将 SSIS 中的日期转换为字符串？

Question

我得到了错误，

将数据类型 varchar 转换为日期时出错。

从这个表达式

(DT_STR,30,1252)@[User::ToDate]

DO NET 源 [40]：执行提供的 SQL 命令时发生错误：“EXEC [dbo.StoredProcedure] @ToDate = '01-maj-2018'

错误：导入时出现 0xC004706B（请参阅表达式！），SSIS.Pipeline：“ADO NET 源”验证失败并返回验证状态“VS_ISBROKEN”。

@ToDate = '01-maj-2018'

如何更改它，使我的 @ToDate 将是 01-may-2018 而不是 01-maj-2018？

我尝试搜索并且有很多类似的问题，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？

我同意@AlexanderVolok，看起来包的 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 @987654325 将日期转换为具有不同格式的字符串@，例如 （假设您正在处理波兰语月份名称）：

@[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) 更改数据格式为 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)

Answer 2

您的包裹的 LocaleID 似乎不同于 1033（英语-美国）。

这个值可以在包级别进行调整，所以所有底层任务都会继承它。

如果值是在 SQL Server 端生成的，也可以与 SQL Server 登录的语言设置相关

不确切知道错误，但我认为这可能是由于 SQL Server 排序规则，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会对您有所帮助。
