SYMPTOMS

Consider the following scenario:
  • You have a Microsoft SQL Server Integration Services 2005 (SSIS 2005), Microsoft SQL Server Integration Services 2008 (SSIS 2008) or Microsoft SQL Server Integration Services 2008 R2 (SSIS 2008 R2) package that contains a Data Flow task.
  • You use a Flat File source to import an input data file in the Data Flow task.
  • The input data file contains at least two columns. One column has a data length that is larger or less than the output column width. The data length of the next column is one byte longer than the output column width of that column.

    For example, the data length is 6 in a column that has an output column width of 50, and the data length is 9 in the next column that has an output column width of 8.

    Note You can specify the output column width in theFlat File Connection Manager Editor dialog box.
  • You specify the data type of the columns so that data conversion occurs. For example, you specify the DT_WSTR Unicode string data type for the columns. Therefore, data conversion is performed if the data type of the input data file is ANSI.
  • You run the SSIS package.
In this scenario, the data of the column that precedes the column in which the data length is one byte longer than the output column width is not imported.

Note If there are more than two columns that meet the conditions in this scenario, only the first column that precedes a column in which the data length is one byte longer than the output column width is not imported.

WORKAROUND

To work around this issue, avoid the data conversion in the Flat File source, and then perform the data conversion operation after the data is imported.

For example, you can specify the DT_STR stringtype instead of the DT_WSTR Unicode string type for the columns if the data type of an input data file is ANSI.
