Re: [sqlite] Roll-back
Yes, it worked after I added 'begin' and 'end' at the beginning and at
the end of my transaction:
db.exec("begin;"+
"select * from t1; " +
"delete from t1 where t1key = 1; " +
"insert into t1(data,num) values('Speedy', 3); " +
"select * from t1;"+
"select * from t106;"+
"end;", cb);
db.exec("rollback", cb);
Thanks

Re: [sqlite] Roll-back
That should not stop you from starting a transaction and committing it.
Note that Sqlite will automatically wrap your SQL in a transaction is
you don't specify one.

Once a transaction commits, there is no built-in way to undo it. You'll have to invent an application-specific undo mechanism in that case. -- D.
