SQLite API deficiency

I've been bitten by this too, but didn't get time to delve into it.

Can the compile/step definitely not handle multiple queries?
That's a shame :/

I'm currently in DB API mode (working on PDO), so I'll refresh my memory
and do some sqlite stuff over the next few days; if there is no way to
get the compile/step executing multiple queries, then we will need a new
function as you suggest.

I have discovered that SQLite function sqlite_query runs sqlite_exec
function if it's return value is used and
sqlite_compile/sqlite_step combo
if return value is used. I think this is a problem - if I
want to run some
pack of queries (like, create whole DB schema in one call), I
can do it
with sqlite_query - but only if I don't check the return
value - and thus
don't know if it succeeded or not! If I check the return
value, it runs
sqlite_compile/sqlite_step, which can not run multiple SQL
statements.

I think this should be fixed. In order not to break BC, I
propose to add
new function to SQLite API - sqlite_exec, which - surprise! -
would always
call sqlite_exec and would return only true/false. Though,
the even better
solution would be to kill that return_value_used check
altogether and use
two separate functions always, depending on the task.

Any thoughts about this?

You could always check the status of the query by running the
sqlite_last_error().

Good idea.

I'd prefer to have sqlite_exec() like you propose and leave sqlite_query() as
is.
