Update Value Directly In The Same Query
Is it possible to update a value directly, adding text to it, without getting it first, adding the text in php and then do the update.
for example:
value in field users: ",45,"
and then adding ,34, to the field directly by doing something like:
update table set users='users,34,'
so the value in the field afterwards will be ",45,,34,"?

Using MyISAM Directly
Has anybody had experience accessing MySQL tables via MyISAM library? I'm working on an application that has to have both SQL-like and DBM-like (file-level) access to the table data. I thought that using MyISAM directly would be a good idea. If anybody has any better suggestions, I am all ears. Also, I was wondering if it's possible to use Berkeley DB tools and libraries to access MySQL data files, which are set to use BDB as the storage engine. If it is, can somebody point me at some examples (except what's in the source already).

Joining Tables Which Aren't Directly Related
I'm struggling to get my head round a SQL query and wonder if you might be able to help (I'm using MySQL version 4.1.20-1). I have three tables: accounts, items and invoices. CREATE TABLE accounts ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, ... PRIMARY KEY (id) ) ENGINE = InnoDB; CREATE TABLE items ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, accounts_id INT UNSIGNED, ... PRIMARY KEY (id), FOREIGN KEY (accounts_id) REFERENCES accounts (id) ON DELETE SET NULL ) ENGINE = InnoDB; CREATE TABLE invoices ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, items_id INT UNSIGNED, ... PRIMARY KEY (id), FOREIGN KEY (items_id) REFERENCES items (id) ON DELETE CASCADE ) ENGINE = InnoDB; Each account can have multiple items and each item can have multiple invoices. Hope you're with me so far? So here's the question. If I have an account ID, how do I get a list of invoice IDs for that account when accounts and invoices aren't directly related?

Inserting Small Image Directly Into Database
How do you insert an image into a table directly using something like data studio? I have tried googling it and it seems all the examples are using a language to do it for you. The images are between 2-4k and the table is just an int column followed by a blob column. I just thought the statement would go like INSERT INTO sometable VALUES (1,'image.jpg'); The web suggests uploading and downloading in PHP (which im using) but im building the data first using data studio then just displaying the table information using PHP. Before i go into displaying the information on the page i just wanted to make sure the insert query is correct.
How To Insert Images Directly Into Mysql Table
Im working on a page for photographer. And he wants some amount of photos to have there and change it whenever he would like to. I thought i put all the photos in mysql db and i would pull it out to webpage using variables. But Im stuck already in the first step - STORING THOSE IMAGES INSIDE A TABLE OF DB. I read about BLOB and avr_row_length and max_rows, but nothing is working. The image is stored in many rows and the output is just strange symbols. I also read those long, hard-mind taking scripts how to upload image using php. But i dont want to slowstep through php, uploading file etc, I just want something like: LOAD DATA INFILE 'image.img' into table tbl_name; and then using php on my page to display it.

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? I've been working on this query for 2 or 3 hours now and I've been making reasonable progress but now I am really stumped.
MySQL Administrator Backup Directly To Local Database

Update Query
I am trying to do a custom sortup/sortdown function in php on a mySQL basis. Now I got that prob: I got a table, that has a "sort"-field for each data like that: data | sort a | 1 b | 2 c | 3 d | 4 e | 5 The output of the data is ORDER BY sort ASC. Now I want the users allow to change the "ranking"/"sorting" themselves that way, that they click e.g. on sort entry d one up. So the new table should look like that: a | 1 b | 2 c | 4 d | 3 e | 5 Does anyone know how to do that in one or only a few mySQL queries? I mean I could read out the whole table and then do a php-loop giving new sort-numbers to each data and then update every single data, but I guess there should be an easier way in mySQL. My prob is that I suck big time at mySQL

Slow Update Query
I have about 2000 update queries to do, which takes about 1 hr on 250,000 rows.

With this query I am basically finding and replacing some columns based upon another table (within the php script I am using)

Stuck On Update Query
I am struggling with a SQL statement and hoped someone would be able to help customer_depots contacts Each table contain fields called 'customer_depot_id' and 'address_id'. What I want to do is update the address_id in the contacts table, with the value of the address_id in the customer_depots table, only where the customer_id values match in each table, AND the address_id in the contacts table is equal to zero. Does this make sense? So, update address_id in contacts, where address_id in contacts = address_id in customer_depots and address id in contacts = zero. This is because a number of address_id's are missing from the contacts table, and I want to replace them with the correspondingvalue from the other table. I have figured out a SELECT statement as shown below, but I need an UPDATE statement as explained above. SELECT cd.ADDRESS_ID FROM customer_depots cd, contacts con WHERE con.CUSTOMER_DEPOT_ID = cd.CUSTOMER_DEPOT_ID AND con.ADDRESS_ID = 0

Maximum Query Update?
Is there a maximum amount of fields that you can update at once as run from php the following works: UPDATE `members` SET `firstname` = '$formfirstname', `surname` = '$formsurname', `usrlevel` = '$formusrlevel', `usrname` = '$formusrname', `grade` = '$formgrade', `phone` = '$formphone', `email` = '$formemail', `comments` = '$formcomments' WHERE `ID` = '1' LIMIT 1 ; Yet the following does not and it only has one extra field to update: UPDATE `members` SET `firstname` = '$formfirstname', `surname` = '$formsurname', `usrlevel` = '$formusrlevel', `usrname` = '$formusrname', `grade` = '$formgrade', `phone` = '$formphone', `email` = '$formemail', `drivingdate` = '$formdrivingdate' `comments` = '$formcomments' WHERE `ID` = '1' LIMIT 1 ;

SELECT And UPDATE In One Query
Does there exist a way to do a SELECT and an UPDATE in one query? What I am trying to do is building a shop that´s articles are saved in a mySQL db and I wanna count the impressions of each article that is shown by e.g. a search function. would be something like that: article no | text | category | impressions 1 | aaaa| 1 |1 2 | bdsd| 2 |1 3 | aaaa| 2 |1 4 | bdsd| 3 |1 and so on now I want e.g. to search for all articles that are in category 2 AND add +1 to the impressions cell of those articles that are found. I hope it´s understandable what I am trying to do. I guess it should be possible, but since I only so far used very simple queries I am not sure how to?

ON DUPLICATE KEY UPDATE And Query Cache
After bludgeoning my head against the table for a bit, I figures out what the problem was that had been plaguing me. When using a INSERT INTO ... ON DUPLICATE KEY UPDATE ... statemtent, it seemed like the update was not taking place. After viewing the webpage in question, (and doing the manual select statement), the old data was being returned. I couldn't figure out why, until FINALLY, I added 'RESET QUERY CACHE' manually after the statement. Then the correct updated info was returned. Apparently the query cache is not flushed after using the above ON DUPLICATE KEY UPDATE statement, like it does with other insert or updates. What do I do now. Just not use that statement? Id like to avoid locking tables if possible. And I cant have the website showing the outdated info.

URGENT: Please Help Me With My ON DUPLICATE KEY UPDATE Query
Could you please help me do this quickly. I have a query: Quote: mysql_query("INSERT INTO products (id, title, brand) SELECT id, title, brand FROM prodse WHERE approved=1 ON DUPLICATE KEY UPDATE groupname=a") What I need it to do is that whne title and brand matches, it is then a duplicate listing. I have set up the unique key for this. When a duplicate listing is found it will then change the groupname value from "1" and update it with "a". When it then finds the next duplicate listing that has the same title and brand as the duplicate listing that had it's groupname changes to "a", I need it to be change to "b" this time. So I now have two listings that have a groupname of "a" and "b". Now when there is more duplicate listings that have the same title and brand as "a" and "b", I now need the groupname to be updated to the actual listings id and not use "a", "b", "c", etc... How can I do that. I know how I can do the first one so that it updates to 8, but then how would I do the 2nd and 3rd ones. Please help, I have to do this urgent as my database is really slow and it is damaging my site as it is taking about a minute or so to do each query. Also, I would prefer it if it could be done in one single query. I can also use variables in the query and if statements plus other php like Quote: mysql_query("INSERT INTO products (id, title, brand) SELECT id, title, brand FROM prodse WHERE approved=1 ON DUPLICATE KEY UPDATE groupname=$groupname")

Optimize UPDATE Query With Subquery
Users(users_id,...,pictures_average_grade) - 5,000 rows Pictures(..,average_grade,users_fk) - 50,000 rows One User can have many pictures.

I wrote the following query: UPDATE users AS u SET u.pictures_average_grade= (SELECT AVG(average_grade) FROM pictures WHERE users_fk=u.users_id). The problem is that the query is being processing very long (after 15 minutes i resing and stop the query).
Update A Set Of Records In One Single Query
My records contain a position, from 1 to n. This position is not the primary key. In normal conditions, the position of this records should be as follows: 1, 2, 3, 4, 5, 6, 7, 8, 9 . etc... One of my utitities is meant to check the consistency of the table - one of the things it has to do is scan the table as follows: SELECT position FROM employe_records WHERE employe_id = ? ORDER BY position From the result of this query I verify each entry (JDBC) one by one, looking for inconsistancies. In a for() loop I look at the value of position and check that they start from 1 and are incremented by one for each record. At the first inconsistency I come accross I want to run a query to update the records so it is consistant again - it is something like this: UPDATE employe_records SET position = updatedValue FROM employe_records WHERE employe_id = ? ORDER BY position This is not valid query of course - my question is what should my query look like?! How can I make 'updatedValue' incremented by one automatically so each of the records are updated from 1 to n.
Convert UPDATE Query To INSERT

I have to restore the database from scratch so there are no existing table rows to update.

In a for() loop I look at the value of position and check that they start from 1 and are incremented by one for each record. At the first inconsistency I come accross I want to run a query to update the records so it is consistant again - it is something like this: UPDATE employe_records SET position = updatedValue FROM employe_records WHERE employe_id = ? ORDER BY position This is not valid query of course - my question is what should my query look like?! How can I make 'updatedValue' incremented by one automatically so each of the records are updated from 1 to n.
Update Query Where Values Will Come From Other Table
I'm creating an update query which the value will come from another table. I have here my current query which unfortunately makes the system hangs. Probably because of the query itself is not properly coded. update boxes b inner join messages m on b.ctnnumber = m.ctnno set b.consigneerecv = m.CName, b.consigneerecvdate = m.DateRcv, b.phrecventered = "Y", b.PhilStatus = "delivered", b.prevreleasestatus = b.releasestatus, b.releasestatus = "delivered", b.PhilStatusDate = m.smsrecvdate, b.phdelprice = "0.00", b.phdelamt = "0.00", b.recvrelation = m.Relation, b.APRecventered = m.smsRecvDate where b.consigneerecv = '' or b.consigneerecv = 'NA' or b.consigneerecv is null; I'm thinking revising it so that it will not cause the system to hang but I don't know how. Guys please help me with this one. I also have this another idea which probably will not work. My idea was something like this: Update table1 set table1.column1 = (select table2.column1 where table2.column1 = table1.column1), table1.column2 = (select table2.column2 where table2.column1 = table1.column1), .....
