Hello, I have an attribute table of earthquake data (focal mechanism beach balls) and need to edit the depth attribute. Each ball is defined by two rows in the table, eg first ball
Row_ID Strike Dip Rake Magnitude Quadrant Depth ---------------------------------------------------------- 0 NULL NULL NULL NULL Tensional and Compressional NULL 1 233 38 -96 6.77 Compressional 623 2 NULL NULL NULL NULL Tensional and Compressional NULL 3 68 36 83 5.7 Compressional 39 etc where rows 0,1 and 2,3 represent separate beach balls, so basically it is a row calculation What I need to do is replace the Depth NULL value with the depth 623 etc for each entry. Is there an easy way of doing this? Thanks Lester _______________________________________________ Qgis-user mailing list [email protected] List info: http://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-user
