I'm unable to figure out how to query vector attribute tables on my Mac using the sample North Carolina data. I'm trying to query one of the vector files has a column "CANCER" with attributes 'yes' or 'no'.
What I'm doing: 1. Choose Vector > Query with Attributes 2. In the v.extract window that opens... - On the Options tab I choose my input vector map and type a name for an output vector - On the Selection tab, in the "Where conditions of SQL statement..." field, I type in my query, "CANCER=yes" 3. I click Run In the output window, I get the following error: --------- DBMI-DBF driver error: [...] Column 'yes' not found Incompatible types in WHERE condition. Error in selecting rows Error in db_open_select_cursor() --------- Is there a db/SQL issue with GRASS on a Macintosh? If so, can it be fixed? Why would it think "yes" is a column instead of an attribute? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Vector-attribute-query-errors-on-a-Mac-tp5365200p5365200.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
