Allow me to show my ignorance here, but I use the tcl bindings to SQLite AND I am SQL-naive. All my stuff (so far) have been done with
sqlite db <mydb-name> ... db eval "insert|update|delete ..." ... How does one get the return code to determine that the DB is locked? Would I change my call to be set rc [db eval "insert|update|delete ..."] Thanks for letting me go to school on your issue!
