The message gets cleared on various calls so you'll want to get it as
early as possible after knowing there is an error. For example
sqlite3_errmsg(db) does not provide the correct error message but
sqlite_exec(...) does.
I have attached my test code. You can compile it by doing below:
gcc x.c -lsqlite3

Thanks, nice and simple.
I had come up with something that works as well, but probably more complex
than needed. This is with my actual data:
delete

rowid not in

Thankyou Dennis.
You have been a fantastic help.
I will be sure to put credits in my script to you all.
I am hoping to release this ranking system after its run for a month or so.
Eventscripts is free and so are the scripts that get released.
I am sure a lot of Counter Strike Source game

Hi, I think there is nothing available except FTS.
Doing a full table scan and computing for each string the (Levenstein) distance
to the query object is too time consuming. So what I would like to see is the
implementation
of a generic metric index which needs as one parameter a metric distance
I believe Sqlite implemens Soundex as standard. Thet might work for you.

When I tried reproducing this behavior on a Red Hat box, the 3.5.9
version gave the expected results, so I guess it is a Debian unstable
specific issue.

In each row, do you want balance before that row's credit/debit has
taken place, or after? <= does the latter, < would do the former.

Hi Tim,
select count(*) from sqlite_master;

Hi,
I have a PHP script that I run in Terminal under OS X, which opens an sqlite db
and works on it. Trouble is, if the db doesn't exist then the PHP library
silently creates an empty db with the given name. Given this, I need to detect
that the empty db has
been created, delete it, and exit.
thank you. But I have a question : is rowid growing with dates ? I believed
that rowid is the original order, not the index order (???). I'm going to
look at this.

Good ! I've not seen like this !
but why "where t2.DATE <= mytable.DATE" instead of where "t2.DATE <
mytable.DATE"
because what about if ACCOUNT soon exists with no null value and you want to
update?

Richard,
Just a suggestion.
Would it make sense to ask one of your document maintainers to add
something similar to your explanation and add it to the "SELECT"
documentation page as a note to using the WHERE clause and the "INDEX"
documentation page

you can do it with a subquery, like
select o.date, (select sum(credit - debit) from bank i where i.rowid <
o.rowid) from bank o order by rowid;
but it would be _much_ more efficient to handle it in your host application
as you loop through the data.
Notice that I used rowid instead of date

I'm learning SQL and have some difficulties to resolve some simple problems

Im facing a wierd issue when thread 1 is doing a sqlite3_exec and if

Any suggestion, on how the memory should be freed or are there any

Hello friends,
I came across a new problem. My database is currupted.
When i ran the integrity check then i found the following results:
*Is there any tool available which can repair it?*
*Result:*
RecNointegrity_check

On tree page 581 cell 1: invalid page
Well, I assume SQLPrepare allocates and locks appropriate resources. I need to
only check the sanity of the statement, and then discard.
So I was wondering if there was a way to do it, instead of prepare statement

You can use sqlite3_complete. It does not check the grammar. It just makes

No. You will have to rely on your backups.
If you have no backups, you may be able to retrieve some data from your
tables by using the .dump command in the sqlite shell. Try dumping
individual tables.

This wouldn't do what you think it does. HAVING clause applies to the
whole group, not to individual rows. It determines whether the group

You speak as if sqlite3_prepare() were a huge burden -
Hi!
We have a 14MB SQLite database on a 16MB flash disk. The journal file gets to
big on some queries, which results in a
SQLITE_FULL error.
Any other ideas to make data storage secure?
