推荐答案

@CreatedAt是SP的输入参数，因此当您调用它时，您必须提供数据来填充它。当你创建SP时，不会发生错误，当你调用它时会发生这种错误。所以试试：

@CreatedAt is an input parameter to your SP, so when you call it you have to provide the data to fill it. The error doesn't occur when you creta ethe SP, it happens when you call it. So try:

EXEC dbo.spAddVoucherCheck @CreatedAt='Hello', ...

BTW：名称@CreatedAt暗示这是基于日期的数据：如果是这样，那么不要将其存储为NVARCHAR - 而是使用DATETIME字段 - 它会使您以后对数据执行的所有操作变得更加容易。因此，SP的@CreatedAt参数也应该是DATETIME。

BTW: the name @CreatedAt implies this is date based data: if so then don't store it as NVARCHAR - use a DATETIME field instead - it makes everything you do with the data later a lot, lot easier. As a result, the @CreatedAt parameter to your SP should be DATETIME as well.
