不存在从 '%1' 到 '%2' 的数据类型映射。请检查源和目标的数据类型、长度、精度、小数位数和为空性。在系统表 msdb.dbo.sysdatatypemappings 中查询支持的映射列表。

Data type mapping from '%1' to '%2' does not exist. Review source and destination data type, length, precision, scale, and nullability. Query the system table msdb.dbo.sysdatatypemappings for a list of supported mappings.
