Navicat for SQLite Lite appears to do this. I copied a db, and used it to rename a table. I then used the sqlite command tool on the db and entered .schema which showed that the table name was changed. The following had taken place: Before: create table mytab1 ( … ); create table mytab2 ( … ); After: create table mytab1 ( … ); create table "wiggy" ( … ); Note the quotes around the altered name. What it's doing internally I don't know, and whether it's actually doing everything it would need to do to do the job properly, I don't know either. I didn't do extensive testing, but entering: select * from wiggy; at the command line produced the expected results. This was Navicat for SQLite Lite 9.1.5 under OS X. -- Cheers -- Tim
