我得到错误，
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'
我怎样才能改变它，所以我的@ToDate意志01-may-2018不是01-maj-2018？
我试图搜索并且有很多类似的问题，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？
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。
您的包裹的 LocaleID 似乎不同于 1033（英语-美国）。
该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 Server 端生成的，还可以与 SQL Server 登录的语言设置相关
检查什么会影响 SSIS 中的日期区域设置的相关问题：SSIS 2012 日期格式 dmy vs mdy
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。
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具有不同格式的字符串? :，例如（假设您正在处理波兰月份名称) :

+ "-" + RIGHT((DT_WSTR,50)@[User::ToDate],4)
然后你应该将新变量作为参数传递。
您还可以使用Expression Task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)
