Re: [sqlite] very simple update query failure...
Of course... apologies. I have tried this on command line sqlite 3 (3.6.22),
sqlite 2.817, and also in the sqliteman gui and sqlite database browser,
all on an Ubuntu linux box.

One important thing you are missing is that you are not telling us how
you are selecting and updating. Are you using the command line,
another program, a programming language... and, which version of

[sqlite] very simple update query failure...
I'm new to SQLITE. I'm trying to update a series of text entries for book titles that were entered with underscores. I want to convert them to spaces. I can run the query: select replace(title, '_', ' ') from books; and see the output I'm looking for, but if I try to do an update query and actually perform the change: update books set title = replace(title, '_', ' '); it fails with this error: Query Error: no such function: title_sort Unable to execute statement I'm sure I'm missing something simple here, but it's driving me crazy... any ideas?

The performance gain is not restricted only for select but also for update, delete, insert. You can measure this easily with a table where you define a primary key with "int primary key" (results in at least one b+tree and one btree) and the same table with "integer primary key" (results in one b+tree). The op asked for a performance difference using integer keys and string keys and for sqlite a "integer primary key" is the recommended solution due to implementation and documentation. It's clear that you'll loose this performance gain when you don't use the primary key to access your data but that's not what the op asked for as far as i understood his question.

An integer primary key substitutes the rowid column of a table. While another type of primary key always results in a second reference table (key ==> rowid) the integer primary key doesn't need a second index table. This results in a performance gain because the engine hasn't to look up the rowid in the index table to find the correct rowsets assigned to a primary key but looks directly in the data table. If you can't won't use a integer primary key as described in the documentation the performance difference between strings and numbers won't be a big deal not as long as your strings have a lenght between 1 and 10 characters cause the greatest part of the time needed to look up a key ==> rowid pair is spent with io operations to read the fileblocks. When your strings get longer you'll find, that string keys will get slower because the number of key ==> rowid pairs fitting in a btree decreases with the length of the entries. This will only matter if you get more levels of pages counted from the root page. As long as you result in the same height of btrees you won't measure a big performance loss due to the use of strings as primary keys when you don't use the "integer primary key" feature. The argument with Timing of assembler instructions would only matter if you use memory databases but even then you'll end up with "virtual memory paging" or "caching". If there are no reasons to avoid "INTEGER PRIMARY KEY" you'll have a real performance gain by using this feature !!! ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

Re: [sqlite] String Vs Integer Index
I think you should be asking 'How fast is SQLite locating a key in a integer column index vs a string index'... Generally, integer keys are faster in key lookups than string keys, because comparing a integer value is a single CMP CPU instruction versus a more-complicated string comparison (that can be virtually unlimited in size).

Re: [sqlite] SQLite - IIS, PHP and java
Hi, the important question is: What about updates to the database? Will there be concurrent updates, or will the db be read only? Will some processes read an others write? What amount of traffic do you expect on the site?

[sqlite] SQLite - IIS, PHP and java
Hi there, I am at the research stage of a project i have been asked to undertake. At the moment the O/S will be windows server 2003 and the web server IIS. These are set and i cannot change them. I will be using PHP to deliver the web content to users and also a Java application will be used to integrate to third party product. Both PHP and Java will be accessing a SQLite db concurrently. SQLite, Java App and php will all be on one box. So my questing is should this setup work OK? Is there anything i should be aware off. Thank you for any help, pointers Alexis -- View this message in context: http://old.nabble.com/SQLite---IIS%2C-PHP-and-java-tp27530283p27530283.html Sent from the SQLite mailing list archive at Nabble.com. ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
