Category: File/Data IO Group: None Status: Closed Resolution: Fixed Priority: 5 Private: No Submitted By: michael michaud (michaudm) Assigned to: michael michaud (michaudm) Summary: Saving long attribute name into shapefile Initial Comment: Mail from Jukka related to bug id 3472008 : What might happen when user is saving into shapefile a dataset with attributes like long_attribute_name_01 and long_attribute_name_02? Truncating names to suit the .dbf format would yield to identical names. This is how GDAL behaves: Attribute names can only be up to 10 characters long. Longer names will be silently truncated. This may result in non-unique column names, which will definitely cause problems later. Starting with version 1.7, the OGR Shapefile driver tries to generate unique field names. Successive duplicate field names, including those created by truncation to 10 characters, will be truncated to 8 characters and appended with a serial number from 1 to 99. For example: a → a, a → a_1, A → A_2; abcdefghijk → abcdefghij, abcdefghijkl → abcdefgh_1 Taken from http://gdal.org/ogr/drv_shapefile.html -- Comment By: michael michaud (michaudm) Date: 2012-04-19 07:28 Message: Feature added in r2777 (2012-03-24) -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=679909aid=3472020group_id=118054 -- For Developers, A Lot Can Happen In A Second.
