hello,
Is there a way to not create a database while the db file is not found with the
sqlite3_open function ?
Why don't just create a create_table function instead of ?
regards,
fred.

There is no ~/sqliterc or config file. SQLite is an embedded database
engine; applications use it in application-specific ways.
Hi Ralf
Thanks for the tip.
I checked it out, and it's a bit complex, but looks very clean. I'll
probably update to that component set at a later date.

Is there a good way/tool to determine what went wrong in a database file
reporting SQLITE_CORRUPT?
The details I have so far are: machine (running Windows XP) locked up hard
while executing our application. Repeatable hard-lock at a certain point.
(Hard lock is defined as no mouse, no keyboard,
I'm looking for your help solving a performance issue:
Master db and an attached db. called A
Table x and table Y are identical in both the master and Attached database.
table Z is built to determine the set of rows to copy and has an index on the
id field.
The goal is to move data from many
I have solved the failed tests reported a few days ago, and I have now
the proof that none of them is blamed on sqlite.
For what it is worth, here are the details:
The source is sqlite 3.4.1 last updated on August 9
The platforms and compilers are:
- Enterprise 3, 32 and 64 bits, gcc 3.2.3

It is. At least it is for the purpose of computing column
affinity. For the INTEGER PRIMARY KEY you are required to
spell out "INTEGER". We cannot change the
Hallo,
where can i find information about how the config-file should look like and
what is possible?
And is there a site with informations about sqlite in other languages avaible?

Depends on the type specified for 'foo' in the CREATE

SQLite doesn't store statements. I guess you are asking how the value is
stored.
That depens on how the column

DISQLite3 (http://www.yunqa.de/delphi/sqlite3/) does not expose such problems.
You might find that using one thread and accessing the four data sets
sequentially yields you a better result. You will use the one Sqlite
cache and get some benefit from not creating and detroying multiple
caches and connections.

Sqlite has a feature where you can contanenate SQL statements and
prepare and step them in a loop. Prepare returns a pointer to the start
of the next statement.
The basic prepare/step/reset activity requires that there be a loop to
handle multiple rows, busy returns and possible errors.

I'm trying to load the FTS2 extension in Delphi, using the Aducom

with the parameter to sqlite3_enable_load_extension().

Pretty much. It has to be valid during all subsequent calls to
When using sqlite3_bind_text() (or a similar function) with
SQLITE_STATIC, how long does the pointer have to remain valid? As long

It is clear to me the following will cause no problem:

Suppose I have a simple table with an integer primary key:
CREATE TABLE table (
id INTEGER PRIMARY KEY NOT NULL,

and insert values without supplying a value for the primary key:
INSERT INTO table (name) VALUES (@name);
Is it guaranteed that the primary key is always
Hi, guys.

Stephen,
You should look into using the newer prepare/step API functions
instead of the callback mechanism. It will make your code clearer, and
will probably execute faster as well.
I don't think so. Prepare/step mechanism can invoke productivity of
"INSERT"
Several reasons. Main one is that we won't be allowed as this is a third
party application clinical database. The other one is that it would cause
too much slow-down of the regular clinical front-end application.
This is reporting software and apart from some rare exceptions there is no

Hi Dan,
Thanks for your suggestion.

Running sequentially might trouble me as I have to update more sets of
information at a cause of single event.
