Hi, I'm trying to join vector layers using v.patch and run into the 'column types differ' error.
I can see the difference relating to the data type of a column via the attribute table in GRASS. However, is there a way through GRASS that I can modify the data type? I've tried opening the DBF file in openoffice, but after saving the changes they seem to be lost on reopening the DBF file. I've also unchecked sheet/document protection in openoffice. Have also tried exporting as CSV and reimporting and saving as DBF in openoffice. Would welcome any suggestions on the simplest approach. QGIS also does not appear to allow changing of data type through its GUI interface. Thanks, Richard Output: v.patch -e input=THA_adm0@GADM,LAO_adm0@GADM output=THA_LAO_admin0_patch ERROR: Column types differ (Wed Apr 4 19:43:49 2012) Command finished (0 sec) -- View this message in context: http://osgeo-org.1560.n6.nabble.com/v-patch-error-Column-types-differ-tp4686430p4686430.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
