Flat File Connection Manager Editor (Advanced Page)

Use the Advanced page of the Flat File Connection Manager Editor dialog box to set properties that specify how Integration Services reads and writes data in flat files. You can change the names of columns in the flat file, and set properties that include data type and delimiters for each column in the file.

By default, the length of string columns is 50 characters. You can resize the length of these columns to prevent truncation of data or excess column width. You can also update other metadata to enable compatibility with destination columns. For example, you might change the data type of a column that contains only integer data to a numeric data type, such as DT_I2. You can make these modifications manually, or you can click the Select Types button to use the Suggest Column Types dialog box to evaluate sample data and make some of these changes for you automatically.

To learn more about the Flat File connection manager, see Flat File Connection Manager.

Options

  • Connection manager name
    Provide a unique name for the flat file connection manager in the workflow. The name provided will be displayed within SSIS Designer.

  • Description
    Describe the connection manager. As a best practice, describe the connection manager in terms of its purpose, to make packages self-documenting and easier to maintain.

  • Configure the properties of each column
    Select a column in the left pane to view its properties in the right pane. See the following table for a description of data type properties. Some of the properties listed are configurable only for some flat file formats.

    OutputColumnWidth

    Specify a value to be stored as a count of bytes; for Unicode files, this value corresponds to a count of characters. In the Data Flow task, this value is used to set the output column width for the Flat File source.
