OK, Thanks for the answer ... one more thing, abusing your kindness, I read that there is a command (I think it is vacuum), which is equivalent to the order to compact the database
If it is true that there is this command ... as would be implemented?
:sign0013:Hello, I can not run the VACUUM command in my application ... SQLite processes the command and it not returns error, but the database continues with the same size, which is what I do wrong?
