1) I am looking for a way to use ogr command-line utilities to modify the contents of fields within a shapefile. It isn’t a problem to modify one step at a time/put in a loop where each change creates a new output – that is manageable – but I’m missing the SQL statement to say “if FIELDX=’abc’, then FIELDB=’123’. I could use the select statement to pull out only the records where FIELDX=’abc’ (+ other statements, then merge back), but how to I set FIELDB=’123’?
2) As an extension to the above question, I’d like to modify the values based on a time statement – something along the lines of “if DATE_FIELD is = (CURDATE – 1), then FIELDX=’24h’”. Can these SQL date queries be made through OGR?
3) The above questions aren't really gdal development questions - is there a more appropriate forum to submit these “use” questions?
