Join Table Based On Specified Condition
Is it possible to join two tables based on the specified condition in MySQL. For example, i have two tables t1,t2 and t3. The table t1 and t2 has field called name and the table t3 has field name class. I want to select the names from t1 or t2 based on the condition of class(t3). If class=4 then select name from t1, if class=10 then select name from t2.tell the query in mysql.

Joining Tables Based On Condition
I want to have a field determine what table the field should be joint on. For example, I have a field that is one of eight different values (contacts, leads, accounts, ect...). I want to be able to join on the specific table specified by the field because this field determines what type the id field corresponds to.

Query Based On 'does Not Exist' Condition
Let's say I have a table called 'forumtopics' with a field representing the topic author's username. I then have another table called 'ignorelist' which has two fields; one is an account number and the other a reference to the aforementioned author. There can be many ignored authors for any one account. For any given account number, I'd like all the rows from the forumtopics table where there is no match for (account, author) held in the ignorelist table. Obviously it's easy to check for existence but can the opposite be done? I run MySQL 4.0.17.

Join Condition
i have 2 tables users relations in the table relations i record relations.user_id and relations.connection those two fields refer both to the same id in the users table. Now to the problem: I want to do a query for one user, and find his friends, therefore i have to search both fields in the relations table, and then depending on where his id was found select the counterpart. (if his id was found in the relations.user_id i need the relations.connection and the other way round...) now i do not only want the id of the friend but i would like to pull his details from the users table.... to be honest i tried a few things but i need a hint whether this is possible or whether i need two queries... or maybe a subquery.

Putting A Condition On A Join
I have two tables: users and events. events has id, event_id, name, and date. I need to select all users, but check if each has an event today or later, and if so select the date of the next event. But if there is no such event the user should still be selected. Of course I'm using a left join, but the problem that is killing the query is the stipulation with the date being today or in the future. I'm trying something like: select users.name, events.date from users left join events on users.id = events.user_id having events.date >= curdate(); But it returns no result if there is no such event for that user.

Date Based Left Join
I have two tables that I want to join to find groups that do NOT have transactions for a particular date range. The left hand table holds the groups. The right hand table holds transactions which have an associated date. The link between the tables requires 2 fields, group_id and storecode, and there is a one-to-many releationship between groups and transactions. I essentially want the left join between these two queries: select g.name, g.group_id, g.storecode from groups g select t.group_id, t.storecode, count(t.trans_id) from transactions t where t.proc_date >= '2005-10-01' group by t.group_id, t.storecode Unfortunately, when I join them together the date seems to be interfering with the join. Naturally, you can't check the date of a transaction that doesn't exist, and there are transactions for the groups somewhere in the transactions table. Joined like this, they return everything I want except the groups with 0 transactions for the date range: select g.gname, g.group_id, g.storecode, count(t.trans_id) from groups g left join transactions t using (group_id, storecode) where t.proc_date >= '2005-10-01' or (t.group_id is null or t.storecode is null) group by t.group_id, t.storecode I could easily add a HAVING clause at the end to get the rows with count = 0, but it is only returning one zero row, when I know there should be about 100. Anyone have any suggestions, or know what I'm missing?

Join Or Combine Two Tables Based On Unique Column
I use MySQL query browser and have made two tables in one database: First table: Test Column names: Filename (Varchar(255)),RowNumber(Integer),Bestandsnaam (Varchar(255)), Pad (Varchar(255)), Grootte (Varchar(255)), Created (Varchar(255)), Modified (Varchar(255)), Accessed (Varchar(255)), Deleted (Varchar(255)) Second table: Hashtest Column names: Filename (Varchar(255)), RowNumber (Integer), MD5 (Varchar(255)), SHA1 (Varchar(255)), Pad (Varchar(255)) Of both tables the column RowNumber is the primary key. Also, in both tables the column Pad is the same (the same content, not exactly in the same order) Now, I want to combine the two tables into one table, based on 'Pad' I suppose I have to use the Script function of MySQL query browser. Please explain to me what I have to do to combine the two tables into one table. This third table has this columns: Filename (Varchar(255)),RowNumber(Integer),Bestandsnaam (Varchar(255)), Pad (Varchar(255)), Grootte (Varchar(255)), Created (Varchar(255)), Modified (Varchar(255)), Accessed (Varchar(255)), Deleted (Varchar(255)), MD5 (Varchar(255)), SHA1 (Varchar(255))

Random Field (condition, Multiple Table, Compare)
Assume i have two tables. "accounts" and "accounts_logs" "accounts" (accid, type) "accounts_log" (accid, ip, timestamp) Here i want to choose a radom 3 accids from "accounts" if available, but each of them should be compared with "accounts_log". Lests say a one of the accid chose is A1, then take users IP and current time - time(). now compare A1 exists in "accounts_log" with the ip, this can exist multiple times but pick one with latest timestamp. Compare the difference in hours in the timestamp and current time, if its less than 12 hours then choose a different accid from "accounts" which goes through the same check, and while taking new accid from "accounts" or if it is greater than 12 hours continue to be A1, this is same even if there is no entries of A1 in "accounts_log". I hope my explanation was enough. I been trying for weeks and yet can't seem to find a solution. I'll summarize the steps 1) have to take 3 random `accid` from `accounts` with `type`='normal' 2) while taking, check each `accid` from `accounts` exists in `accid` feild of table `account_logs` with number '123' in `ip` field of `accounts_log`. 3) if exists compare the latest `timespamp` field of `accounts_log` associated with `ip`='123' to current time to see if it is greater than 12 hours.

Updating Table Based Upon Matching Field In Second Table
I have a database of books that was originally created as a flat file. Each record has a number of fields, including the authors name. I'm trying to convert the database to something a little more efficient. I've created a new table (called Authors) of unique authors names and assigned each one a unique ID. I've added a new field in the original table (called Books) for the author's ID. Now, I need to update the original table with the author ID from the Author's table. Something like this: UPDATE Books SET AuthorID = Authors.AuthorID WHERE AuthorName = Authors.AuthorName This obviously doesn't work. Any assistance on how to forumulate this query (or, if I'm headed down the wrong path, the correct way to do this operation) greatly appreciated.

List Available Items Based On Prerequisite Table
I'm trying to develop such a scheme: TABLE Prerequisites PrerequsiteID (FK to Upgrades table; states a prerequisite for UpgradeID in the other column) UpgradeID (FK to Upgrades table as well) TABLE BuildingUpgrades BuildingID (FK to Buildings table) UpgradeID (FK to Upgrades table; states what Upgrade Building already has) So it's a Building -> Building_Has_Upgrades -> Upgrades -> Upgrades_Have_Prerequisites thing (Building has 1..n Upgrades, Upgrade has 1..n prerequisites). In order for Building B to have an Upgrade U, that Building B has to have all the Upgrades which are required to have Upgrade U. What I want to do is to list all buildings with all upgrades available for them. I've been trying for almost whole day to solve this issue with different inner, left and right joins, subqueries and what not but I can't really do it in a clean way. The only working thing is a query, which I am ashamed of because it seems like a real waste of CPU time to me: SELECT BUPG.BuildingID, PRE.UpgradeID, COUNT(PRE.PrerequisiteID) FROM BuildingUpgrades BUPG JOIN Prerequisites PRE ON BUPG.UpgradeID = PRE.PrerequisiteID GROUP BY BUPG.BuildingID, BUPG.UpgradeID HAVING COUNT(PRE.PrerequisiteID) = ( SELECT COUNT(PrerequisiteID) FROM Prerequisites WHERE UpgradeID = PRE.UpgradeID GROUP BY UpgradeID ) What it basically does is takes all the available Upgrades, counts prerequisites that have been met by the building and checks if it's equal to the number of all prerequisites for that Upgrade. And it works but I still think there is a much better way to do it.

Table Creation Based On User Login
I'm trying to build a website that will allow the addition of users (w/ username, password, etc.). That seems simple enough. But is it possible to set something up (in PHP, for example) that will create a new table in the database for each new user? Ex. John Smith signs up, is verified, and a PHP script (or Java, or whatever) creates a table specifically for him. I know I'll need a master table of usernames, passwords, etc. These new tables would store certain user-specific data, such as preferences and other data the user might want to restrict access to. I know I could store all of this information in a master table, but I'm trying to think ahead. Worst case scenario, if there are millions of users (unlikely, but not impossible), I'd hate to have all that data in one table, but if I have to, I can.

Detecting Duplicates Based On One Field In A Table?

I want mysql to return all the rows where "title" is the same.

I have found some SELECT COUNT( * ) AS num_entries, title FROM title_table WHERE title >1 GROUP BY title But this doesn't seem to work, although looks like it's on the right sort of lines?

Returning Rows In Left Table Based On Mutliple Criteria In Right
This is starting to get to me. I'm sure there's a simple way of handling what i'm trying to do, but someone might be able to help out quicker than spending another hour searching and testing for this. Here's the problem: Simplified tables: ARCADES ======= ID, name GAMES ====== ID, name ARCADES_GAMES ============= ID, arcade_iD Games_ID Straightforward enough so far right? I'm trying to get all arcades that have ALL games in a passed in set of game_id's. So for instance I might want all arcades that have the games 11 and 14, but it must have both those. I can do soemthing like... SELECT a.name FROM arcades a WHERE EXISTS(SELECT 1 FROM arcades_games WHERE arcade_id=a.id AND game_id IN (11,14)) But that'll return all rows that match ANY of (11,14) rather than ALL of 11,14. It all comes down to the simple thing of getting rows in a table where all criteria from a list is met, but any advice on how i would do something like this?
