Hello! I am new to SQL and have a simple question concerning sqlite. I am using the functions sqlite3_open, sqlite3_get_table and sqlite3_free_table and sqlite3_close.
Because i do not yet know how to check whether a database exists or not, i always call the sqlite3_get_table function. If it returns an error, the database probably not exist. But if this function returns an error, all further calls to sqlite3 fail. In detail: sqlite3_open(...) sqlite3_get_table(...) copy the columns to a string grid if sqlite3_get_table(...) succeeded sqlite3_free_table(...) sqlite3_close(...) The first time sqlite3_get_table(...) fails, no further starts of this sequence work. I get no errors when executing the statements, but there's no table sqlite3_get_table copies to the given pointer variables. There would be two solutions to my problem. I have to check first if a database exists or i have to make sqlite keep on working after sqlite3_get_table fails. Sorry for my poor english. Regards, Jochen
