I'm trying to pull some data from the database in which it's supposed to return 3 rows from each f.forumid in the order in which i have the forumids, however it seems to be returning all the data from the table, what am i doing wrong? PHP Code: SELECT t.threadid, t.title, t.lastpost, t.forumid, t.open, t.replycount, t.postusername, t.postuserid, t.lastposter, t.dateline, t.views, t.firstpostid, f.title AS forumtitle, p.pagetext AS preview FROM thread t INNER JOIN forum f ON (t.forumid = f.forumid) AND t.visible = 1 LEFT JOIN post p ON(p.postid = t.firstpostid) WHERE t.forumid IN(200,250,2,30,15,60,70,90) GROUP BY f.title, t.title HAVING COUNT(*) <= 3 ORDER BY f.forumid, t.dateline DESC

Displaying Data From Three Tables
I have three tables I am working with. There is one table I would consider the "main table" which includes log entries. The log entries in the "main table" store username as a number. A second table has a primary key of a number and the number maps to an actual active directory username. How can I select data from these three tables but have it display the actual username instead of just the userid number (which in and of itself doesn't mean anything)?

Limiting Users' Access To Only Their Data
I'm working on a single database with a dozen or so tables and fifty or so users. Essentially every record has a field defining the user who generated the data; think scientists' measurements. Up until now we have not been concerned with restricting access to the data. Now we would like to implement some security in the sense that a particular user would only be able to interact with his or her data; that is I would like to restrict a user's privileges based on the value of a particular field for all of the records in a given table. Is this possible? One idea I had was to generate a database for each user with only his/her data, and grant the user privileges to only this database. This seems a bit clumsy though. Other than that, I can imagine implementing something through the front end when the data is selected, but this seems problematic because if someone knew SQL and their username and password they would be able to access everyone else's data with another frontend.

Limiting Query Time
Is it possible to limit the query time in MySQL (3.x or 4.0)? For example, I'd like to have any query that takes more than a specified number of seconds just quit automatically. Seems dumb, but on a web site, nobody is going to wait minutes for a query to return so they refresh anyway. So on a busy server, MySQL ends up with several queries running that all take a long time to finish which compound to make it even slower. A simple time limit would solve the problem. Yes, I know that the queries should take less time, but again, on a busy server, sometimes the longer queries do take a long time (10 minutes or more) to complete.

Get 4 Tables Data In One Query
I am new to mysql relational programming, and creating a tutorial site like pixel2life. I am trying to get the data from 4 tables 1st table is main tutorials table, 2nd is subcategory (subcat) table, 3rd is categories table and 4th is users table. I don't know how to do it exactly, I googled but not got the proper method. I only got some hints http://www.brainbell.com/tutorials/M...ing_A_Join.htm from this site. I've created the following query which selects the title from tutorials table, subcategory (s_cat) from subcat table which reference is available as s_cat_id in tutorials table, then category (cat) from categories table which reference is available in subcategory (subcat) table and username from users table which reference is availble in tutorials table. Can somebody tell me this query is correct or there is any alternate method PHP SELECT d.title, s.s_cat, c.cat, u.username FROM tutorials d JOIN subcat s ON d.s_cat_id=s.id JOIN categories c ON s.cat_id=c.id JOIN users u ON d.author_id=u.id

Displaying Certain Amount Of Data
I have created a script. This script of mine takes data off of a table and displays it on a web page. What I want is for the script to display only data that matches the id of another section of the web page. For example, the script would first point to another factor in the database, perhaps the value of a row in another table. Let's call that value 025. In a second table, I have a few rows of data. Their ids were 025, 026, 027 and 028. The web page would only display rows with the ids of 025. However, if that value in the other table was 026, then in the second table, the rows with id 026 would only be displayed.

Displaying MySQL Data On Website

I would like to add the directory to the website, to replace printing it. I can easily create the tables and insert the data. I'm not sure how to go about displaying the directory data. Is there is a way to create a report and display that? Each entry represents a family in the neighborhood, but the fields that contain data may vary from family to family, such as the kids field. Also, I want multiple entries on a page - like a phone book.

Merge Sort-of Similar Data From 2 Tables In Query
A bit of background. I'm not a web person, and I know enough about databases to scrape by. Most of my SQL is generated using templates or handy things (like PHPMyAdmin etc). I'm also not a PHP coder. I am a C/C++ coder so I've found I can hack some PHP together, and I've got roped into helping a friend with a problem Here's the issue. I have a MySQL database with 2 tables of interest. Let's call these tables categorydata and itemdata. Both of these tables contain records that describe individual items - the item name, its ID in the system, the date it was added, some free text about it etc. To be absolutely clear, the purpose of the categorydata table is for a record to define a category (think "puzzles", "board games", "vegetables", whatever), but the record row also includes data on the FIRST item in the category ("banana", "cluedo" etc) along with all its data. The purpose of the itemdata table is to list all the OTHER items in the category ("grapes", "twister" etc). Here's an example record in the categorydata table: categoryname vegetables categoryid 1234 categorycreated 10th Jan 2000 categoryowner Bob firstitemid 4567 firstitemname cucumber firstitemcreated 12th Jan 2000 firstitemdesc It's long and green Here's an example record in the itemdata table: itemid 4568 itemname orange itemcreated 13th Jan 2000 itemdesc It's round and, er, yeah. This seems really bad design to me but what do I know. Here's what I need to do. I need to know how to merge the data in these 2 tables in a single query, ordered by the itemid and firstitemid fields. In other words, I need the query to merge the data, ordering it so that regardless of the table the record came from the itemids are all in correct numerical order. I need to do this so that I can retrieve each item's data in order. itemid in the itemsdata table and firstitemid in the categorydata table are unique, so when merged there won't be any colliding ids. I need to put this in a PHP script (in a loop that dumps out all the items in order), but if someone can just help me with the SQL query syntax I'd appreciate it, I can do the rest. I think this has something to do with inner joins but I really don't understand how to make it work, or how to retrieve and merge data from 2 tables at once bearing in mind the fields (columns? what do you call them) have different names even though they have the same purpose (ie: firstitemid -v- itemid, firstitemname -v- itemname etc).

Determining Which Table To Query Based On Data Within Tables
I have 2 tables: default_categories column 1: category_id column 2: category_name column 3: category_parent custom_categories column 1: custom_cat_id column 2: custom_cat_name column 3: custom_cat_parent The custom_categories table won't necessarily have anything in it but if it does, I need to choose the data from the custom_categories table over the data from the default_categories table. So if the default category has 3 rows with IDs | names: 123 | Dogs 456 | Cats 789 | Fish And the custom category has 1 row with IDs | names: 456 | Very Cute Cats I want my query of these 2 tables to produce the following IDs | names: 123 | Dogs 456 | Very Cute Cats 789 | Fish I've tried joins like the one below but they aren't working because if there is no custom_cat_id, it won't give me the result for the default category_id. MySQL SELECT * FROM default_categories LEFT JOIN custom_categories ON category_id = custom_cat_id WHERE category_parent = '' AND custom_cat_parent = '' ORDER BY $order_by $sort

Limiting Inner Joins
This has been bothering me and the relation isn't typical of the other expressions I've had to build. I have a table of 250 records that I'm returning ie. SELECT B.ID, B.Title, B.Owner FROM blogs AS B WHERE B.Status = 0 I need to return not only the blog name but the latest post they've made on their account. So what I did was used: SELECT B.ID, B.Title, B.Owner FROM blogs AS B INNER JOIN archives AS A ON B.ID = A.BlogID WHERE B.Status = 0 But when I do this it returns each record in archive with the relevent blog information. What I would like is for it to determine the latest ID insert on the blog. So if he has posts IDs such as 1010, 1050, 2063 and 2075 then it will return the blog information and the results of record 2075 in the archives table. I've tried a couple ways so far but each fails, I think what I want to do is somewhat limit the return on the inner join...sort of like add a WHERE clause unto the clause. I would have done this with a stored proc. or a view but I'm using MySQL 4 and I want to keep the querying function in my code for now. Not sure if that makes sense to the experts, if my problem isn't clear let me know I'll explain it further.

Extending The Limiting Of Results
I have a table which is updated continuously and has over 2 million records in it, lets call it table A. The records have a "category" field and also a "date" field. Is there a way to get the most recent 10 records for each category in a single query? I know I can use "ORDER BY date DESC LIMIT 10" to get the 10 most recent records from the table, but I would like to extend this to get the most recent 10 for each category. I guess it would be the equivalent of (SELECT * FROM A WHERE category='cat1' ORDER BY date DESC LIMIT 10) UNION (SELECT * FROM A WHERE category='cat2' ORDER BY date DESC LIMIT 10), etc... It seems like there must be an easier way using a JOIN or something?

Limiting Records Retrieved
I have a results database where users can be members of groups and can submit results for themselves as a member of the group. The tables involved are GROUPS, GROUPMEMBERS and RESULTS. I can easily get all of the result records for the users who are members of a particluar group. What I'd like to be able to do though is (for example) get the last 5 results records for each group member. I'm stuck with how to do this. Obviously I can select all of the users in a group and then step through the results set doing a new select to get the results for each user and using LIMIT 0, 5 Is there a smarter way? I get the feeling I ought to be able to do it in a single go by using a SELECT within a SELECT or similar but I just can't get my head around it.
