Is like that, I now need to check the results for the first time use sqlite3_step to obtain, and then wrote a while (rc==SQLITE_ROW) of a loop, in the while loop, with the resulting value to the query, and performed a sqlite3_step, increasing data on the database after the deletion operation is displayed "datebase is Locke," but the query is not an error, this is why, is there a tall person to give directions, thank you!
