ssis - 错误 : 0xC0202009 at Data Flow Task, OLE DB 目标 [43] : SSIS Error Code DTS_E_OLEDBERROR. 发生 OLE DB 错误。错误代码:0x80040E21

Question

我的源是 TXT 平面文件源，目标是 OLE DB 类型。 (见图)

我发现了一个非常basic tutorial on Code Project创建一个包。我完成了这些步骤，但是在调试时出现了一个奇怪的错误(如下):

有人可以解释一下这个错误吗？我花了几个小时在网上搜索错误。

There was an error with OLE DB Destination.Inputs[OLE DB Destination Input].Columns[AppID] on OLE DB Destination.Inputs[OLE DB Destination Input]. The column status returned was: "The value could not be converted because of a potential loss of data."

Answer 1

之所以发生此错误，是因为源中的 AppID 列值对于目标中的 AppID 列无效。

一些可能的例子:

• 您正在尝试将 10 个字符的值插入到 8 个字符的字段中。
• 您正尝试将大于 127 的值插入到 tinyint 字段中。
• 您正在尝试将值 6.4578 插入到小数 (5,1) 字段中。

SSIS 由元数据控制，它希望您正确设置输入和输出，以便两者的可接受值在同一范围内。
