Hi,
I have a SHP file of some 1.1m polygons, of which I need
to select about half of them, and save them as a separate
SHP file.
The trouble is when I select either via a Query, or via
the TABLE using the select options below, it just falls
asleep (100% CPU (ok, 12% as it must be single-threaded)).
After 45 minutes or so, I just kick it out and weep.
My platform is Win 7 Prof 64 bit (also tried on 32 bit)
and using 1.8.0 Lisboa.
The selects I have tried are: "sq21code" = "C016*" and
also tried using "IN"
Any ideas what I am doing wrong and what I should try
next?
Still no:
zls@gs0:~$ ogr2ogr -f "ESRI Shapefile" -where " 21DigitKey
LIKE 'C016%'" zerf.shp
/mnt/geo_lvm0/SGO_cadastral/200909/WC/Erf.shp
ERROR 1: SQL _expression_ Parsing Error: syntax error
FAILURE: SetAttributeFilter( 21DigitKey LIKE 'C016%') failed.
zls@gs0:~$
21igitKey BTW is "String" 60
I think the problem is the attribute column name begins with a
digit. Look what happens when I rename my column from above to
21Name:
[micha@MS-SL6 bike_rides]$ ogr2ogr -f "ESRI Shapefile" -where
"21Name LIKE 'Rest%'" waypoints4.shp waypoints.shp
ERROR 1: SQL _expression_ Parsing Error: syntax error
Can you rename the column to DigitKey21?
Thanks & regards,
Zoltan
