Maybe you are too C++ orientated. You have no need to touch any Sqlite
structure, that is what the API does. Just use it.

Mike, if you are going to implement a lock server, why not finish the
job and include Sqlite in the server, then you will not have a problem.

What do you think, was my reason to ask, whether these structures are public
and stable or not ... ;-)

Hi,
I can not find the maximum of an 'INTEGER AUTOINCREMENT' field. Is it greater
thar 50.000.000 ?
Thanks

It's a signed 64-bit value. The larget representable value is

I have an old port of Sqlite for Palm OS mentioned at
the wiki page:

Other ports to Palm OS are also listed on the same

Hi Dennis
Thanks for your answer. You have see my problem and its solution.
I look sometimes at SQLite with my "OLE-DB"-Eyes. In OLE-DB is
the Recordset Reader and Writer allways at the same time.
Now I consider this... and it works fine.

Hi to all
Today I inserted as a Test 100 Records in my DB. I repeat therefor
100 times the same "Insert into...". The Job starts and I wait,
and wait, and wait.
I say, Programm hangs or died, because I do a Mistake in Code.
But it isn't.
The Job needs really so much time. Trace-Message
Anne,
Try wrapping your inserts in a transaction. Individual inserts are
quite fast, but transactions are not. Therefor anything that you can do
to reduce the number of transactions will boost the speed. My
preference is to wrap a transaction around every 200 or 300 inserts,
depending on

Declare it static in the class declaration, not at the function definition.

I'm receiving sql errors like the following
"no such table: main.phs_matrices_1"
when trying to create an index using the syntax:
"CREATE INDEX IF NOT EXISTS phsm_1_idx ON phs_matrices_1 (a, b, c)"
from my C++ program.
The error statement is true - phs_matrices_1 doesn't belong to main,
but
The documentation says to put the database name on the front of the
index name, not the table name when using the create index command. I
thought it was weird myself.

If you use the bind/step API calls instead you don't need to use callbacks.
It's much cleaner with C++. If you want examples you can look at the source

Anne, you don't say that you make your 100 inserts a transaction.
Unless you do that the ACID feature of Sqlite will make it slow as it
has to finalize each insert onto disk before starting on the next.
Within a transaction it will do the 100 inserts then finalize the entire
100 onto disk in
You don't seem to need a data manipulation system like Sqlite, more a
form of high volume storage. Do you really need elaborate SQL,
journalling, ROLLBACK and assured disk storage?
Di you consider some form of hashed storage, perhaps linear hashing, to
