UNION, Individually Works Fine, But Not In Union
Well, I am using an UNION, and while both of the queries works fine while used individually, they don't work while in the UNION. Here is the code - PHP ( SELECT * FROM job WHERE date_fin !=0000-00-00 ORDER BY date_fin ASC ) UNION ( SELECT * FROM job WHERE date_fin =0000-00-00 ORDER BY date_creation ASC ) What do u think guys? Note : MySQL version 4.1.21 Note : Not working means, this part is not working => 'ORDER BY date_fin ASC', means, the returned results are not ordered as I want. MySQL doc. tells, To apply ORDER BY or LIMIT to an individual SELECT, place the clause inside the parentheses that enclose the SELECT: (SELECT a FROM t1 WHERE a=10 AND B=1 ORDER BY a LIMIT 10) UNION (SELECT a FROM t2 WHERE a=11 AND B=2 ORDER BY a LIMIT 10);
Union In Mysql 3.23

Mysql Union
I have been developing a mysql application for a month on one machine, time to move to another, much to my surprise it has 3.23.58 and there is no way to change it. Now all of my union queries are broken. I found one solution: CREATE TEMPORARY TABLE temp_union TYPE=HEAP select * from asdf; INSERT INTO temp_union select * from qwer; SELECT * FROM temp_union; DROP TABLE temp_union; Now I ask, how efficient is this? I mostly use the union in two places: a search query where I aggregate a search from three tables, and a favorites list where I aggregrate favorites from three tables. So using the above methods I would need to create 2 temporary tables for each query. I am using php as a frontend, would it be better to do 3 queries and aggregrate everything in php? the only reason I do it on mysql is because I also need a sorting.
Mysql Problem With UNION
I have a strange problem with a UNION of 3 queries. The 3 separate select-queries return (at this point) respectively 4, 3 an zero rows, but the UNION returns no rows at all. When I take the query that returns 0 rows, and put it in front of the other two, everything to go fine (I get 7 rows), but this is of course no real solution, next time another query returns zero rows.
MySQL 5.0.1 : CREATE VIEW And UNION
I don't manage to create a view from the UNION of two tables. This statement works all right : CREATE OR REPLACE VIEW myview AS SELECT 1 AS mycol UNION ALL SELECT mycol FROM mytable2; This one does not : CREATE OR REPLACE VIEW myview AS SELECT mycol FROM mytable1 UNION ALL SELECT mycol FROM mytable2; and I get the error "ERROR 1143 (42000): create view command denied to user 'root'@'localhost' for column 'mycol' in table 'myview'", although I am creating the view using the "root" account. Version used : MySQL 5.0.1 alpha snapshot (Windows binary).
Equivalent Of 'UNION' In MySQL Syntax?
How can I express this in MySQL syntax? (SELECT Value, Name FROM orderTable WHERE id = '1jn8') UNION (SELECT Value, Name FROM orderTable WHERE ct_id = '12dNOI') UNION (SELECT Value, Name FROM orderTable WHERE country = 'US').
IF Function,GROUP BY,aggregate Function Problems
Yep, I have all those problems in the title. So I'll explain each one at a time - I did have another thread relating to this very same query but I thought it was time to update where I am with the query because at the moment I feel like I am getting nowhere! The query I have basically searches through an items_ordered table through each product and checks to see whether the item is VATable or not. This is not where I have the problem though. Where I am really having the first problem is when I am trying to use the IF function to check if the TOTAL of an order is over £300. IF it is then I multiply it my 0.95 (i.e. 5% off). With the query below I get no errors but neither do I get the desired result. It's as though it couldn't even see it. =....
Mysql Function
i am hosting my website on a hosting website server. I made Mysql database there. I noticed one thing when i insert data in tables they have a colum called "function" with drop down box where they have values like ASCII,CHAR,SOUNDEX, UCASE, LCASE, COUNT,AVG any many other. I don't pick any of them. But I am just wondering if I need to pick either ASCII or char?

Mysql 4 Function From A Mysql 5 Function
I found this function on the mysql website : CREATE FUNCTION substrCount(x TEXT, delim varchar(100)) RETURNS int RETURN (length(x) - length(REPLACE(x, delim, ''))) / length(delim); That works perfectly with mysql 5. But when I try to import this to mysql 4, I have an error : suse-server:/partages # mysql mybase <function-add.sql> output.tab ERROR 1064 (42000) at line 1: You have an error IN your SQL syntax; CHECK the manual that corresponds TO your MySQL server version FOR the RIGHT syntax TO USE near '(x TEXT, delim varchar(100)) returns int return (length(x)-length(REPLACE(x, del' at line 1

MySQL Now() Function Problem
I am new to MySQL and my problem is with storing a datetime value in a table. I created a table with a column designated as DATETIME. I fill it with the NOW() function. No matter whether I default it or try and set with code, all I get is a date! Even running "SELECT Now()" only returns a date. If I run the following query: Date_Format(now(), GET_FORMAT(DATETIME,'USA')) it returns a datetime value. However, if I use that SAME query to try and fill the column during insert, I still get only a date value. I've even tried some date calculations like Now() + 0 but still get ONLY a date, no time info.

Mysql Stored Function ...
I'm new to creating stored procedure - can someone tell me where i've gone wrong here - the below code refuses to execute.

Push/pop Function For MySQL
if MySQL has a push/pop function? I'm creating a table for news items, with three rows - one for the date, one for the title, and one for the URL. What I want to do is limit the number of news items held in the table to 10. For example, if there are 10 entries in the table already (date/title/url sets) and I add another item, I want to put it at the top of the table and pop the bottom value off the table. I know I can do this by exporting the table to an array in PHP, then messing with it there and writing it back to the table, but this would take a lot of MySQL queries I think. Is there an easy solution to this problem I'm not seeing?
MySQL IF() Function Problem
I want to select 2 dates from a database (fields called start_date and end_date). However, I want to in some way make the returned value of end_date equal to that of start_date if end_date is null. I've tried using the if() function as follows: $result = mysql_query("select start_date, if(end_date is null, start_date) from events"); Where events is my table name. This doesn't work. I've tried it with quotes around start_date in the if but that just returns the word start_date.
Variable Function In MySQL
Is there a way to use a 'variable function' in MySQL, e.g.Code: SELECT @hash:= value FROM prefs WHERE key = 'hash_method'; -- @hash = SHA1 SELECT @hash('test string'); So the variable @hash stores the current hash method in the `prefs` table. This method does not work, is there a way to do this?
An IMPLODE() Type Function For MySQL??
I'm looking to pull data (just one column) from mysql which is over multiple rows. e.g. apple banana orange pear Now, I actually want the data in this format in just one row: "apple,banana,orange,pear" Does mysql offer some sort of "SELECT IMPLODE(',', my_column) AS foo" type of thing? I know I can do it with PHP but this a part of a much larger query so I'm trying to keep this all in a single query.

Mysql 4.x Week Function Fails
I think there is a bug in mysql 4: select week("2003-08-15") from po.orders limit 1; produces: 32 after: set session default_week_format=3; it produces: 33 (which is correct in the Netherlands) The documentation states: set global default_week_format=3; (As root!) This command should set the default_week_format. This command fails: mysql> set global default_week_format=3; Query OK, 0 rows affected (0.00 sec) mysql> select week('2003-08-14'); +--------------------+ | week('2003-08-14') | +--------------------+ | 32 | +--------------------+ 1 row in set (0.00 sec) This result is incorrect. It should be 33. If I use: mysql> set session default_week_format=3; Query OK, 0 rows affected (0.00 sec) mysql> select week('2003-08-14'); +--------------------+ | week('2003-08-14') | +--------------------+ | 33 | +--------------------+ 1 row in set (0.00 sec) This is result is correct... I use mysql 4.0.14. I also did the same test on mysql 4.1 alpha, which has the same results. Harm de Laat Informatiefabriek The Netherlands

PHP/MySQL, No Longer Connecting To Db When In Function
I'm trying to clean up the code so that design changes will be easier. So, I've put the $connection = mysql_connect($hostName,$username,$password) or die ('I cannot connect to the database because: ' . mysql_error()); mysql_select_db($databaseName, $connection); etcetera... with output commands in global functions(). But for some reason (why?), it no longer "reads" the original include with all the database variables. Is there a way to help these new functions "read" the previously set variables?

Problem Logging In Using Mysql Password Function
I have a test server on a windows box with php 4.3.10 and mysql 4.1.10-nt. I built a login app and It works well using the mysql password('') function. Unfortunately I ported the app to a freebsd box running php 4.3.10 and mysql 4.1.12. The passwords come out differently and I don't understand why. For instance, the password test looks like "378b243e220ca493" on the windows box and the freebsd database entry look like "*94BDCEBE19083CE". As you can see, very different. And this causes a lockout from logging in. Instead of being routed to a "safe" login page, the error for a wrong username/password combo shows up.

Mysql Appears To Have Changed The 'password' Function Hashing
I've been using Mysql for about 6 months but in fairly basic fashion. For a cms I have built, I have a users table, with userName and password fields. An admin can create new users, and the password is hashed using the PASSWORD() function. SQL: "INSERT INTO users VALUES ('', '$userName', PASSWORD('$userPwd')) Straight out of the book basically. Now the problem is that all this has been functioning fine on a couple of sites on external servers, plus a couple of local machines. Until today, on my main dev machine - yesterday a user could log in, today they couldn't. As far as I can tell, nothing has changed. But when I look at the hashes in the database table, they are 41 chrs, and when I add a new user, the hash is 16 characters. I know that at some stage the hash length was increased between mysql versions, but I have not updated the install (I run XAMPP for Windows 1.4.14, which appears to install php 5.0.4 and mysql 4.1.12) Is there any other reason that the hash length could change to 16? I'd like to know why this happened so that I'm prepared if it happens on the server (where it is not so easy to hack in and add new users that can log in again)
Union Without Union
I am running version 3.23 of MySQL. It does not allow UNION statements. How can I pull this off without a union. I hear it can be done with a LEFT JOIN SELECT `id`,`name`,`date_of_event` FROM `events` ORDER BY `date_of_event` ASC UNION SELECT `id`,`name`,`date_of_event` FROM `upcoming` ORDER BY `date_of_event` ASC
Using UNION
(SELECT id,name FROM table1) UNION (SELECT id,name FROM table2) UNION (SELECT id,name FROM table3) order by name limit 1; this query is works. I can get the fields values. But i cant get the owner table that i read. for example i get this values 3,george (which table has this record???)
UNION On Ver. 3.23
Are there any alternatives to UNION? Running mySQL ver. 3.23 Upgrade is not an option! My query looks like this: (SELECT sum(t.timer) AS sumtimer FROM emply WHERE t.tmnr = 1 AND t.tjobnr = 69 AND t.tfaktim = 2 AND t.tdato BETWEEN '05/7/4' AND '06/2/1') UNION ( SELECT sum(f2.timer) AS fakbare FROM timer f2 WHERE f2.tjobnr = 69 AND f2.tmnr = 1 AND f2.tfaktim = 1 AND f2.tdato BETWEEN '05/7/4' AND '06/2/1')
Union
I have X number of identical (structure-wise) tables, with one generated for every day. There is a reporting tool which requires that certain data be extracted for a given time period, which can span any number of these databases. My idea is to use a dynamically generated UNION ALL statement which simply joins identical selects for each table. e.g. CODESELECT id, blah, bleh FROM t1 UNION ALL SELECT id, blah, bleh FROM t2 ....
UNION HELP
I have written a PHP search App and I want it to search between like 8 or so tables in one Database.

How To Do A Union
I have a query I need to do that combines two queries The structure for the first table is Application_Period CampusID GroupID IndivID This table uses the lookup table Time to get the groupID and IndivID. TimeID Application_Period TimeID matches GroupID and IndivID. How can I combine the two tables into one without the UNION operator?
