Update Query Fails In Previous MySQL Version
The following query runs fine on my development server (v4.0.17):
"update user inner join events on user.username = events.username
set user.LastMessageDate = '$current_time'
where events.text_sent=0 and events.to_mobile >0 and events.GMT_event_send_time<='$send_time'"
but fails on my production server running v3.23.56.
Anyone any ideas why it doesn't run and what I need to do to fix it?

Query Fails In MySQL 5
I just migrated a Mambo CMS site from a server runing MySQL 4 something to one running MySQL 5.0 and am getting one problem (was expecting many more) with a query generated in the admin section: SELECT c . * , g.name AS groupname, cc.name, u.name AS editor, f.content_id AS frontpage, s.title AS section_name FROM mos_content AS c, mos_categories AS cc, mos_sections AS s LEFT JOIN mos_users AS u ON u.id = c.checked_out LEFT JOIN mos_groups AS g ON g.id = c.access LEFT JOIN mos_content_frontpage AS f ON f.content_id = c.id WHERE c.state >=0 AND c.catid = cc.id AND cc.section = s.id AND s.scope = 'content' AND c.sectionid = ཊ' ORDER BY cc.ordering, cc.title, c.ordering LIMIT 0 , 10 MySQL said: Documentation #1054 - Unknown column 'c.checked_out' in 'on clause' The problem appears to be with the fact that the table mos_content is aliased as c and the the SELECT uses a wilcard to select all its columns. For some reason, when the ON clause test the value in any of the colums using the alias, it says they are onknown.

Update Fails
I'll put this very simply, will give my current code if necessary (first trying to explain it here I came to an conclusion I'd better erase it and only ask..) I have a script, which by using mysql_affected rows, checks if UPDATE query was used to update already existing data. If that fails, INSERT query will create that data. However Mysql only returns affected rows as true, if the old data is different than the new one. What I'm asking here is - Which do you think is the best way to update - or if nothing to update - insert new data to sql. I guess REPLACE wont work when it should be done by id fields?

Master Master Replication, Truncate Table Fails, Version 5.0.22

UPDATE Fails On Somewhat Large Data Sets
I am running into a problem with an UPDATE statement. I am using MySQL 5.0 server, and the mysql command line client that came with it. update tableA a, tableB b set a.value = b.value where a.key1 = 'foo' and a.id = b.id and a.col2 = b.col2; The tables use InnoDB as the engine. With small data sets, this works fine. However, with larger data sets, the UPDATE runs for a long time, then I get an error saying that the number of locks exceeds lock table size. In my case, the data sets in the two tables are < 5 million rows. I kept monitoring the InnoDB status, and see the number of log entries go up until finally rolling back. I saw a bug on the mysql bugsite: http://bugs.mysql.com/bug.php?id=15667 which sounds like the problem I am facing - though my data sets are not as large as the bug states. How do I overcome this issue? I was thinking about splitting the query into smaller ones, using LIMIT and doing some sort of ordering to guarantee same order of rows retrieved. Any better ideas? Maybe configuring the InnoDB differently (I read that the lock table size cannot be changed, darn.)

How To Write Query To Select The Max(version) For Each Unique File_name Record?
I am a MySQL newbie trying to write a query that selects file_name records possessing the highest numbered version for that unique file_name. I show sample data and two trial queries below.

I have contemplated a second table to track the max version for each file name. I would like to structure the data in an efficient manner for query performance when the data set grows to many thousands of unique file_name records with many hundreds of versions each........

Complex Query - UPDATE Within UPDATE?
Edit: Before anyone leaves this thread, don't be put off by the regular expressions! They are not the problem, so please stay and read. OK, this query has got my head spinning. I am basically creating a query that goes through each product in a table to update the stock for that particular item with that particular size (i.e. I am talking about shoes - different models and each model has different sizes (uk kids 12 -> uk 11). With each shoe it does (or is meant to do) the following: 1. The PHP script that runs the query is looping through every size outside of the query 2. So for each of these sizes it checks to see whether the product it is currently on matches the size it is on 3. When it finds the size it is on, it then deducts the correct number of units from the stock table 4. The final WHERE clause makes sure this subquery inside the UPDATE only happens when the StockUpdated field of the Product table equals 0 (in other words, the stock hasn't been counted before) Basically what I need to do, is first to make sure what I currently have got does the above correctly but also I need the query to UPDATE the StockUpdated field to 1 only when it has been updated successfully. How could I do this? Unfortunately I cannot just add an extra update entry to the end of the query as this would update the StockUpdated field regardless of whether it has been properly counted or not. Here is the query I have so far (with a little simple PHP around it doing the loop): PHP $shoesizes = array(1 => 'ukk12','ukk13','uk1','uk2','uk3','uk4','uk5','uk6','uk7','uk8','uk9','uk10','uk11'); $numshoesizes = count($shoesizes); for($i = 1; $i < $numshoesizes; $i++) { $stockupdate = " UPDATE heelys_stock,items_ordered SET heelys_stock.size_".$shoesizes[$i]." = (SELECT CASE WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?( )?(Kids)?( )?( )?(UK)?( )?( )?(Kids)?( )?( )?[^0-9]12( )?(' -- if UK Kids 12 THEN heelys_stock.size_ukk12 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?( )?(Kids)?( )?( )?(UK)?( )?( )?(Kids)?( )?( )?[^0-9]13( )?(' -- if UK Kids 13 THEN heelys_stock.size_ukk13 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]1( )?(' -- if UK 1 THEN heelys_stock.size_uk1 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]2( )?(' -- if UK 2 THEN heelys_stock.size_uk2 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]3( )?(' -- if UK 3 THEN heelys_stock.size_uk3 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]4( )?(' -- if UK 4 THEN heelys_stock.size_uk4 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]5( )?(' -- if UK 5 THEN heelys_stock.size_uk5 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]6( )?(' -- if UK 6 THEN heelys_stock.size_uk6 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]7( )?(' -- if UK 7 THEN heelys_stock.size_uk7 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]8( )?(' -- if UK 8 THEN heelys_stock.size_uk8 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]9( )?(' -- if UK 9 THEN heelys_stock.size_uk9 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]10( )?(' -- if UK 10 THEN heelys_stock.size_uk10 - (items_ordered.Amount/items_ordered.Price) WHEN SUBSTRING_INDEX(items_ordered.Product,',',-1) REGEXP '( )?(UK)?( )?[^0-9]11( )?(' -- if UK 11 THEN heelys_stock.size_uk11 - (items_ordered.Amount/items_ordered.Price) FROM items_ordered WHERE items_ordered.StockUpdated = 0) WHERE (heelys_stock.id = (SELECT heelys_stock.id FROM heelys_stock,heelys_shoe WHERE SUBSTRING_INDEX(items_ordered.Product,',',1) = heelys_shoe.full_shoe_name)) , items_ordered.StockUpdated = 1" // at the moment this last update of the items_ordered table happens to every record!!! even if the other part of query fails // update stock for size $i mysql_query($stockupdate); } Hope someone can see how I can do this?

MySQL Version To Use
I have 4.0 currently installed and I'm coding all my scripts in that version... should I keep using it or should I upgrade? If I should upgrade, what version do you recommend, 4.1 or 5.0?I'm confused because I don't make scripts only for me, I code them and put them available to anyone on my website and sometimes I also have some paid jobs to code some websites using mysql databases and the whole point is to which version should I code my scripts?Not every server on the web is running the same mysql version and if I code something that works on 4.1 but not on 4.0 some people might not be able to run the script.Which version do you think that is the most used on the servers? Should I code my scripts to make it compatiable with that version and up?
