执行 ssis 包时出现数据转换问题
data conversion issue while executing a ssis package
正在执行我的程序包，我看到以下错误。来自源（平面文件）的 EMP ID 是 DT_STR(50) 并将其加载到 table：
EMP_ID int not null column
使用数据转换任务，我将其转换为四字节有符号整数
但是工作失败了。
Description: Data conversion failed while converting column "EMP ID"
(105) to column "EMP ID" (25). The conversion returned status value 2
and status text "The value could not be converted because of a
potential loss of data.". End Error Error: 2019-09-16 11:37:28.53

code 0xC020907F occurred, and the error row disposition on "Data
Conversion 0 - 0.Outputs[Data Conversion Output].Columns[EMP ID]"
specifies failure on error. An error occurred on the specified object
of the specified component. There may be error messages posted before
this with more information about the failure. End Error Error:

Conversion (2) failed with error code 0xC0209029 while processing
input "Data Conversion Input" (3). The identified component returned
an error from the ProcessInput method. The error is specific to the
component, but the error is fatal and will cause the Data Flow task to
stop running. There may be error messages posted before this with
more information about the failure. End Error DTExec: The package
execution returned DTSER_FAILURE (1). Started: 11:37:27 AM

主要错误是：
The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data
源列似乎包含无法转换为整数的值，您可以配置错误输出以将错误行重定向到平面文件目标，以便检查导致此错误的值。
