Sqlite will create a database if it does not find one. You really need
to add a test for the existence of the file, such as an "access".

hello sqlite gang,
I'd like to consult here some possible bug in Qt4 SQL library. I'm fixing
one bug in my Qt4 based application and I see there is propably buggy
QSqlDatabase::open() method in their Sqlite driver. They are using this
routine to open a database:
...
if (sqlite3_open16(db.constData(), &d->access) == SQLITE_OK) {
sqlite3_busy_timeout(d->access, qGetSqliteTimeout(conOpts));
...
return true;
} else {
...
return false;
}
And when I look into sqlite code itself the sqlite3_open16 *always* returns
SQLITE_OK (return sqlite3ApiExit(0, rc); to be exact).
Where is the problem? When I use (in Qt4) e.g.:
db.open("this_is_not_a_sqlite_db.tgz")
I get "true" in the meaning "your file is opened successfully" and I have to
perform an additional check for example by a dummy select statement to be
sure it is a db.
I'd like to know if there is bad usage of sqlite function in Qt4 to report a
bug.
all the best
