Any way to do this short of SELECT.. if (exists) UPDATE else INSERT ? You can do UPDATE ... WHERE keyfield='xxx'; then use sqlite3_changes to see whether any update has in fact taken place, and run INSERT if not.

[sqlite] SQLite join-mechanisms question
Hello. I have a question about SQLite join-mechanisms. Let me explain with an example. I have the follow table. CREATE TABLE a( word_id INTEGER, doc_id INTEGER ); CREATE INDEX a_index1 ON a( doc_id ASC ); CREATE INDEX a_index ON a ( word_id DESC ); And how can SQLite do an optimized join of the follow query SELECT a.doc_id FROM a, a as a1, a as a2 WHERE a.doc_id = a1.doc_id and a1.doc_id = a2.doc_id and a.word_id = 1 and a1.word_id = 2 and a2.word_id = 4 LIMIT 0,20 What the example do is find the doc_id that has word_id 1,2 and 4. And suppose that there is: - 4 docs with word_id 1 - 5 docs with word_id 2 - 353500 docs with word_id 4 What i am searching is a optimized way to join, i mean, the algorithm. And I think SQLite has a great performance with joins. Thank to all. -- Cesar Rodas http://www.cesarodas.com/ Mobile Phone: 595 961 974165 Phone: 595 21 645590 [EMAIL PROTECTED] [EMAIL PROTECTED]

Then you transfer the database to the embedded device. On the embedded device, you specify precompiled SQL statements by number, loading them out of the database as sqlite3_stmt objects. Then you bind host parameters and run sqlite3_step() and sqlite3_reset() or sqlite3_finalize() just like you normally would.

I downloaded the source code file sqlite-3.3.13.tgz and followed the README on how to compile but ran into the problem that the header file tcl.h could not be found, even though I have the rpm tcl-8.4.7-2 installed it is missing the tcl-devel package so the compile fails when I run make. I see there is another way to get SQLite installed by using the precompiled binaries for linux. but where do I put these files tclsqlite-3.3.13.so, fts2-3_3_13.so and sqlite3_analyzer-3.3.13.bin on my system? Also is there an rpm package for RH4 enterprise? Thanks, Brian -- Cesar Rodas http://www.cesarodas.com/ Mobile Phone: 595 961 974165 Phone: 595 21 645590 [EMAIL PROTECTED] [EMAIL PROTECTED]

You are unlikely to be able to fix the rest of the Internet so it is best to expect broken links to the SQLite site. So the wiki server ignores it all and serves up the wiki home page. BTW that is absolutely the wrong behaviour to have. You should either return a 404 as the page really doesn't exist with helpful content as part of the 404 page, or if you really want to show the home page then redirect to it using status 301 Moved Permanently.

An afterthought, why don't you just stat the file and malloc the right
sized buffer from the outset? Much easier.

Re: [sqlite] (newbie) pictures in tables, what's the best way ?

It looks great, compared to ini-files. Now I've a basic problem: I've a table, with 10 simple fields and 1 blob field, containing a (possibly large) image. Uptill now the dbase is small so no performance problems yet. But what if it grows ? I want to look at the table in a table overview, where the blob-field just displays the type of image (identified by the fisrt 2 bytes SOI-code). When I ask for the table through a query, I get all the blob-filed information, while I only need the first 2 bytes, and only the full picture of 1 selected record. I can think of several solutions, but as my experience with databases is almost zero, I can't decide (and maybe I'm overlooking some better solutions) solution 1: add a extra field for each blob field, filled with the first 2 bytes of a blob solution 2: put the blob fields in a separate table, with a link to the main table any suggestions would be appreciated. thanks, Stef Mientki - To unsubscribe, send email to [EMAIL PROTECTED] - -- Cesar Rodas http://www.sf.net/projects/pagerank (The PageRank made easy...) http://www.sf.net/projects/fastfs ( The Fast File System) Mobile Phone: 595 961 974165 Phone: 595 21 645590 [EMAIL PROTECTED] [EMAIL PROTECTED] - To unsubscribe, send email to [EMAIL PROTECTED] -

WindowsXP: inserting 100 records ~11 seconds. inserting 1000 records ~113 seconds. May be I did something wrong for building, or the parameters passed for building sqlite werent correct.

Congratulations D. Richard Hipp. Thank for give us SQLite On 04/01/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Looks it has got faster in my particular situation. Thanks for that. RBS SQLite version 3.3.9 is now available from the SQLite website http://www.sqlite.org/ http://www.sqlite.org/download.html The more important change is a fix for an obscure bug that can lead to database corruption on multi-processor systems. Other important changes include the addition of the sqlite3_prepare_v2() API which new users should always use in place of the legacy sqlite3_prepare() API. A summary of the changes can be found at http://www.sqlite.org/changes.html A detailed listing of all changes can be found by consulting the CVSTrac timeline at http://www.sqlite.org/cvstrac/timeline There are a number of important changes to winCE and win95 support.

Re: [sqlite] Problem with sqlite3 on CGI scripts with ANSI C
Here is fixed your bug.. :D.. I'd use the Option 2.
Option 1:
printf(\nhello [1]);
if (sqlite_open(myDB.db, db))
error_handle(db);
printf(\n hello [2]);
Option 2:
printf(\nhello [1]);
if (sqlite_open(myDB.db, db))
{
error_handle(db);
}
printf(\n hello [2]);

How do you set the working directory? Where is your Sqlite DB file?
You are just opening a file name, not a pathname so your working
directory is whatever your web server uses for CGI data.

I've insert into a C-CGI page a small sqlite3 code.
When i call the page from a browser, it exec a query and show on browser
the entries, but it don't work.
If i add a printf above the sqlite3_open() it print the message, but
if i put the instruction after the sqlite2_open() it don't swow the message.
Under i put my piece of code:
printf(\nhello [1]);
if (sqlite_open(myDB.db, db));
error_handle(db);
