The Column type and Length columns describe the format of a database item. These columns include either the length in bytes of the database item or the Informix data type.

Column type and Length information is included for the user’s reference. Because data gathered through ODBC can be used in a variety of applications, it is helpful to know what type of data you are accessing and how long it is in bytes. Any difference or exception in the column type or length between tables in a table group is indicated in the Column type and Length columns.
