It will take about the same effort as deleting and inserting a row, or about twice as much as inserting a row. Show us your schema and we may be able to advise on optimizations. (output of .schema in the sqlite3 command line tool will do). Note: index is a resserved word. Using it as a column name is confusing. -- ( Kees Nuyt ) c[_] _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
