I know other ways to do. I would like know why it doesn't work. "auxstr is string variable with Insert command in it.
Lets forget my question. Let the error goes on.

Try ExecSQL What is in "auxstr"? What is your Table definition? Since you are updating data using direct SQL, you will need to close and re open the dataset so the dataset record is in sync Luiz 2013/8/5 "Arí Ricardo Ody" <aro52 at gmx.com>: > I use ExecuteDirect method to insert a record in a SQLite3 SQL tabel.
