SSIS：将数据从Excel源导入SQL Server数据库

我正在尝试从Excel电子表格导入数据并使用SSIS将其加载到SQL Server数据库中 .

这是我的SQL Server表：

SQL Server table

我收到了一条消息

由于将数据从长度为255的数据流列“CIN”插入到数据库列“CIN”（长度为50），可能会发生截断 .

对于每一列，并在执行后得到以下输出：

我检查了高级编辑器，Excel源输出列和OLE DB目标输入列的长度都为255，但Excel源和OLE DB目标外部列的长度为50，所以我尝试并更改了SSFS中的数据类型，从nvarchar （50）到nvarchar（255）并获得此输出：

为什么会这样？我该怎么办？
