I do not know what version of SQLite3 you are using, but according to the source code, only strings are compared as strings. Everything else is compared using the appropriate Affinity -- Double to Double, Integer to Integer, BLOB to BLOB, etc. --- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
