MYSQL :: WHERE Accross Multiple Rows

TagCloud SQL Accross Multiple Tables
$sql = "SELECT DISTINCT Tag.handle,Tag.name, COUNT(TAGGED_OBJECT.id) AS tagcounter FROM pages TAGGED_OBJECT ".
"JOIN pages_tags tt ON TAGGED_OBJECT.id = tt.page_id ".
"JOIN tags Tag ON tt.tag_id = Tag.id ".
"GROUP BY Tag.id ";

The above works fine, however I need to extend it to cover more than just the Pages table, I have the following tables I'd like to use:

links
news
pages
resources
products
questions
reports

all have join tables, alhabetically setup, eg:

links_tags
news_tags
pages_tags
etc

Keyword Searching Accross Multiple Tables
been trying to get this to work correctly for some time now - basically i want to search for multiple keywords accross two tables. The query i have already works to a certain extent but doesnt return the exact results i'd like.

I got two tables, both are for a bulletinboard, one contains the threads (bulletinboard) and the other the replies for each thread (bulletinreplys). They're linked via a column called 'threadid' in the reply table. Code:

Retrieve Data Accross Multiple Similar Tables
I have a number of tables that all have the same table format. I want to query accross all the tables as if they where one large table. I am looking to retrieve data base on one of the columns like:

select * from (data_readings.lts4a_line,data_readings.lts12_line,data_readings.lts14_line) where trigger_type='time of day'

the error I get is 'column "trigger_type" in where clause is ambiguous'

is there a way to do all this in one statment?

Enforcing Unique Field Values Accross Multiple Tables
I have 2 tables (t1,t2) with unique keys defined in each. In addition to enforcing unique key values in each table, I would also like to enforce unique key values accross both tables (ex. If key value 'XXX' appears in t1 I don't want to allow entry of key value 'XXX' in t2 and vice versa).

Select / Insert Multiple Rows As A Single Row Of Multiple Columns
I have a nice database set up that contains information about orders and the items on those orders. If an order has 10 items on it, I can select the item data which returns 10 rows of data (let's say 5 colums each). Beautiful!

Now I find myself needing to satisfy a program that requires all of the data on a single row. I can do this in a higher level language, but if I could accomplish it all in mysql it would be better.

I don't need to sum or do any calculations. I just want to select those 5 columns of data about those 10 rows worth of items as a single row with 50 columns.

For example, I'd want this:
1-1,1-2,1-3,1-4,1-5
2-1,2-2,2-3,2-4,2-5

To become:
1-1,1-2,1-3,1-4,1-5,2-1,2-2,2-3,2-4,2-5

The first complication is that the number of items on an order is variable, but is always at least 1 and can not exceed 20. The closest I've been able to get is to do something like:

SELECT GROUP_CONCAT(item_number,",",qty,","",description,"",",price,",",location_number SEPARATOR ",") FROM items WHERE order_number=12345

This will give me a single text string containing the value content of the INSERT query (which will need to be manipuated outside of the SQL query to pad it with NULL values for the unused items' columns etc).

Joins With Multiple Tables And Multiple Rows
I'm making a good ol' forum, and i have three tables, users, threads
and posts. when i query my threads table with a join, i need to access
the users table twice to get the username of the first poster and last
poster. But how? I can only figure out how to get one or the other. Is
my design bad? eg

SELECT TopicID, FirstPostID, LastPostID, Replies, Views, Topic,
username FROM DiscussionThreads, users WHERE
DiscussionThreads.FirstPostID=users.ID ORDER BY FirstPostDT DESC LIMIT
10 .

Passing ID Accross To Another Table?
I am still struggling in getting the user ID (PK) from my user table into my leaderboard_1 table as a FK. I am confused on how to pass this information accross. Below is my code. At the moment a new leaderboard_1 record is created but it gives each record a value of 0!? Code:

Group By Accross Databases
how could I achieve something like this..

SELECT DBname, COUNT(id)
FROM DB1.tableX, DB2.tableX
WHERE DBn.someflag = 1
GROUP BY DBname
The result I'm looking for is something like:
DBname COUNT(id)
===================
DB1 1234
DB2 323
I really needed it to be done in one query (preferebly with no subqueries, due to installed version limitation).

Matching Data Accross 5 Tables
I have a table of projects
I have a linked table containing the required skills for the project
I have a table of skills
I have a table of users
I have a linked table containing the skills held by users

I want to get a list of projects where all of the project skills can be found within a given users skills

Also a bonus for the other way around, ie. For a given project, find all users with all the skills required for a project.

Multiple Rows
I've got a whole bunch of rows to create, each with a unique key.
Each row gets the same value ("New") set in the "Age" column.
I've seen the INSERT INTO table (rows,) VALUES (val for row1), (val for row2),
etc.But what if each row gets the same exact value?

Multiple Rows
I was wondering if it is possible to get all of the inserted id's of an auto increment column when doing multiple inserts at 1 time. For example:

INSERT INTO people (fname, lname) VALUES ('john', 'smith'), ('eric', 'robinson'), ('mark', 'appley');

is it possible to retrieve all of the insert ids of those inserts instead of having to loop through each individual insert and retrieve each individual row id?

Multiple Rows
I create a table with 7 columns
id Mdate col1 col2 col3 col4 col5

as above shown
id is small int, mdate is date and col1 to 5 are tinyint
and i want to insert the values . id is auto increment and i want mdate a day for one row. and other column set to zero
what i want is to enter in single query.

Get Multiple Rows Using Subquery?
I have a query similar to the following, however i'd like to get another row from the subquerys - currency.

SELECT *,

(SELECT xml_result_value FROM lodging_links_allocation
INNER JOIN xml_results ON lod_link_alloc_link_id = xml_link_id
AND xml_result_value != 'X' AND xml_nights = 1 AND xml_source_id = 19 WHERE lod_link_alloc_lod_id = lod_id
ORDER BY CAST(xml_result_value AS UNSIGNED) LIMIT 0, 1) as price_from_1,

(SELECT xml_result_value FROM lodging_links_allocation
INNER JOIN xml_results ON lod_link_alloc_link_id = xml_link_id
AND xml_result_value != 'X' AND xml_nights = 1 AND xml_source_id = 13 WHERE lod_link_alloc_lod_id = lod_id
ORDER BY CAST(xml_result_value AS UNSIGNED) LIMIT 0, 1) as price_from_2,

(SELECT xml_result_value FROM lodging_links_allocation
INNER JOIN xml_results ON lod_link_alloc_link_id = xml_link_id
AND xml_result_value != 'X' AND xml_nights = 1 AND xml_source_id = 12 WHERE lod_link_alloc_lod_id = lod_id
ORDER BY CAST(xml_result_value AS UNSIGNED) LIMIT 0, 1) as price_from_3

FROM (

SELECT *
FROM
[..snip..]
GROUP BY lodging_master.lod_id
ORDER BY RAND(&#55614;&#57159;-12-17')

) as foo
HAVING (price_from_1 > 0) && (price_from_2 > 0) && (price_from_3 > 0)
LIMIT 0 , 30

Multiple Update Of 21 Rows
I have a database table which holds price ranges for various classes of hire car and various hire periods. There are 7 different hire classes and 3 different hire periods. 21 records in total.

Heres an example of what the table contains:

ID......HIRE PERIOD.....HIRE GROUP....PRICE
1..........14.....................a...............25.00
2..........28.....................c...............15.00

The rows are shown in an editable form, which is basically a grid of text fields.

I need to figure out the most efficient way of updating all the records when the grid is edited. Do I need to perform 21 individual updates? as I'm worried that this will be too cumbersome when there are multiple users.

I thought of one way which involves having a hidden field for each row, called 1,2,3 etc, each with a value of eg. 14,a,25.00 as a comma seperated list. Then I split the post values into arrays and perform various updates.
Seems a bit clunky though,

Count Multiple Rows
I have a table that tracks dealer transactions. The fields are Date, Dealership, Amount, A, D, W, F. A=Approved D=Denied, W=Withdrawn and F=Funded. I have made it where if a loan has been approved then A would =1 and D W F would be null. Same goes if the record was withdrawn W would =1 and the other would be null.

So here is my problem:

I want to group by dealership and then count how many were approved, denied, withdrawn, and funded. i am running version 3.23.58. After doing much research I either need to do unions or subqueries. However, both are not availble until 4.x. Is it possible to do what I am looking to do without upgrading?

Update Multiple Rows
I have about 20 rows that need to updated together and would rather not have 20 seperate update lines but am not sure what else to do. At the moment it looks something like this:

UPDATE movies SET mon='10pm', tues='10pm', wed='11pm' WHERE movie_id='19'...
UPDATE movies SET mon='9pm', tues='11pm', wed='4pm' WHERE movie_id='37'...
UPDATE movies SET mon='8am', tues='1pm', wed='5pm' WHERE movie_id='19'...

There is no logical order to the movie_id's they are selected from the movies table using specific criteria.

Collapsing Multiple Rows Into One.
I'm setting up a database of links, where each one can be in multiple categories. I could make each category id a column in the links table, but I'd rather store it in a separate table so I don't have a bunch of NULLs cluttering up the main table and also to allow unlimited categories. That table has two columns, linkid and categoryid. The problem is that I'd like to retrieve it as one row somehow, something like this: "linkid category1 category2 etc..."

Updating Multiple Rows
The following UPDATE query works fine if run directly into phpMyAdmin (I take the $sql output of the script with the data in it and paste it into phpMyAdmin).

But it doesn't update my records if run from the PHP script. I can't seem to figure out where the bug is: Code:

Selecting From Multiple Rows??
i have made a voting script... every time someone votes it goes into a table called 'voting'... since people can vote on multiple things in the site there are multiple instances of each user in the 'voting' database...

if each entry has a 'userID' a 'ratingGiven' and a 'objectBeingVotedOn' field
how would i go about grabbing say the "ratingGiven" field from all of one particular user's entries .

Updating Multiple Rows
I need to update multipule rows a once, using PHP. Here's what I mean.

I have a mysql query out put the data as a form like this:

Item 1
<input type="hidden" name="id" value="1">
<input type="text" name="order" value="">

Item 2
<input type="hidden" name="id" value="3">
<input type="text" name="order" value="">

Item 3
<input type="hidden" name="id" value="4">
<input type="text" name="order" value="">
<input type="submit">

Order need to be updated. I could setup to do a loop with multiple queries.

Update Multiple Rows
I have an array that I need to put into an existing db column using a perl foreach loop. I can do this using an INSERT statement but the script will be run every day and the source array will be changing as it is based on directory contents so I need to UPDATE vs. INSERT

With the INSERT statment the script places each array element on a new row of the db as it should but when I try to use an UPDATE statement, I get a single array element written over and over on each row of the db. Code:

Insert Multiple Rows
I want to insert multiples rows and use sintax
"INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);".

But, I get the following error: "Column count doesn't match value count at row 1".
The number of fields is the same, only that insert multiple rows.

How To Insert The Same Value In Multiple Rows?
i just added a new column to one of my tables. it is an int column, and is currently
assigned 'NULL' in all instances. How can i insert, for instance, the value 0 into all rows?

Inserting Multiple Rows Of Same Value
I have an auto-incremented column and I need to be able to insert one value hundreds of times. Does anyone know an efficient means of doing so?

How To Evaluate Multiple Rows As One Using IF( )
Each record for a PhysicalSource has a Status number. I need to do a SELECT statement to find out if there is a Status = 2 in any of the records.

If Status = 2 then I need to return all rows for this PhysicalSource else if Status != 2 then I need to exit the query (donâ€™t return anything).

The statement is as follows:

SELECT SourceID, OriginalTime, State FROM sources WHERE SourceID = ? AND PhysicalSource = ? AND IF(Status = 2, 0, 1) Order by SourceID ASC

As I found out the â€œIF(Status = 2, 0, 1)â€� evaluates every row and returns all others with Status !=2.

The options are limited, I inherited a GUI (canâ€™t modify it) that must be use and only accepts one query at a time using MySQL version 4.1.11.

Could someone help with a way to have this evaluate multiple rows, as one, and if in any of them Status = 2 then exit the query?

Matching Multiple Rows
I've got the following tables with the following columns:

property: id, address, number_of_bedrooms
attribute: id, title (e.g. washing machine, central heating, furnished)
property_attribute: property, attribute (composite primary key on both id columns)

what i'm trying to do is select property ids that have all the attributes i'm looking for, for example, all those properties that have a washing machine and are furnished.

I've been trying things like the following which aren't working, probably because the attribute column won't be equal to two different values at once.

SELECT pa.property FROM property_attribute AS pa INNER JOIN attribute AS a ON pa.attribute=a.id WHERE a.title='washing machine' AND a.title='furnished'

this is returning an empty set because, i think, a.title can't have two values at once. what i want to say in pseudo-sql is:

SELECT pa.property FROM property_attribute AS pa INNER JOIN attribute AS a ON pa.attribute=a.id WHERE
(pa.property=X AND a.title='washing machine') AND (pa.property=X AND a.title='furnished')

so the only results that will be returned are where a property has both attributes.

i can't think of how to do this since there will be varying numbers of attributes i need to search on. perhaps i need to use a variable for pa.property - i tried that, setting it to SELECT DISTINCT property FROM property_attribute, but mysql didn't like it because this query returned multiple rows. i may need some kind of set variable or an array.

Select Multiple Rows With The Same Id
So I have this table:

table_name

id_one ---- id_two
1 ---------- 1
1 ---------- 2
1 ---------- 3
2 ---------- 1
2 ---------- 3

I want to select all of the id_one rows where the id_two is '1' and '2'. The desired output is:

id_one
1
1

Later I might use SELECT DISTINCT to produce the following:

id_one
1

So far I have:

SELECT id_one FROM table_name WHERE id_two IN ('1','2')

But this selects all the id_one rows where id_two is '1' OR '2'. I want the rows where it is '1' AND '2'.

Delete Multiple Rows At Once
My question is, what code would i use to delete multiple rows of data at the same time.
if i had:
username password userid
john fubar 13402
mike yippy 13679
and i wanted to erase both users in one query, what would it be?

Subtracting From Multiple Rows.
I'm wondering if it's possible to subtract a single value from multiple rows. For example, say I have two rows containing pieces of an account balance, which add up to a total balance. We'll say the two rows hold balances of $10 and $20. Now I want to subtract $25 from them (meaning subtract $20 from one and $5 from the other). Is there a way to write this in one query? If I use the SUM() command can I subtract from the total instead of each unique row?

Updating Multiple Rows
I am running the following UPDATE statement

UPDATE history
set t_own = t_user * 0.75
where user_cur = 7
and lg = 'Local'

t_own and t_user are defined as DECIMAL 12,2

650 rows should be updated, but i get

error 1136 Column count doesn't match value count at row 1.

Insert Multiple Rows At Once
I was faking it a couple of years ago when I made my first database for my photography website. Now I'm updating it and I'm inserting One item at a time manually thru PHP. It's slow and tedious and I've got 467 entries to do.... I'm sure there's an easy way of doing it all at once. I'm just too much of a retard and I'm too tired to try to learn some MySQL tonight. Could someone please help me?
Here's the query that I'm ending up with. (I started at Number 100, I'm increasing the Number by 100 each time and I need to go to Number 46700.)

SQL query:
INSERT INTO `Headshots` ( `Number` , `Category` , `Name` )
VALUES (
'2800', 'Head', ''
);

Updating Multiple Rows.
I went to MySQL home page and found one comment that kind of tried to explain it but it was written in such a manner that I could make no sense of it at all.
I am trying to find a way to update a row with 12 entries in a table that has 12 teams (teamid) and 12 ranks (r1,r2,r3...r12) the data to update the teamid comes from a form and they would all be updated (unless everything remains the same) with the use of the said form.
I am not certain how to make this work (call the table 'team')

PHP Code:

UPDATE team SET teamid='team1', teamid='team2'...teamid='team12' WHERE?

Adding Multiple Rows Into A Table At Once
I have to the stage of being able to easily(?) add new rows to my tables using the command

insert into zone_vs_weight
(low_mass, high_mass, zoneA, zoneB)
(1, 250, 4.50, 6.35);
It seems to work well for adding single rows but can we use it to add multiple rows i.e.

insert into zone_vs_weight
(low_mass, high_mass, zoneA, zoneB)
(1, 250, 4.50, 6.35)
(low_mass, high_mass, zoneA, zoneB)
(251, 500, 6.50, 8.50)
.........;
Is there another command apart from the input file insertion or using PHP?
I have been using K. Yank's fine book 'PHP & MySQL' as a good primer but it doesn't seem to mention whether it is feasible.

Updating Multiple Rows In One Query
tried to find the answer with search but didn't return any answers.

OK, here is the table

table test
------------------------
| test_id | test_order |
------------------------
| 1 | 1 |
------------------------
| 2 | 2 |
------------------------
| 3 | 3 |
------------------------
I'm trying to change the orders in one query, but not sure how to do that.

phpMyAdmin shows me the code like this

Quote:

$sql =
'UPDATE `test` SET `test_order` = ƈ' WHERE `test_id` = 1;'
'UPDATE `test` SET `test_order` = Ɖ' WHERE `test_id` = 2;'
'UPDATE `test` SET `test_order` = Ƈ' WHERE `test_id` = 3;'
. ' '

I'v tried that but got a syntax error.

MySQL version is 4.0.26, can anyone help please?

Adding Up Data From Multiple Rows?
If I have numerical information stored in different rows what is the best method to find the sum of all the numerical information in the rows?

How To Update Multiple Rows With One Query?
I am using PHP/MySQL and need to update 7 rows with one query. Can someone tell me how to do the following so it will update the row for each day of the week? (This obviously doesn't work)

$sql = "UPDATE business_hours SET hours='$sunday' WHERE id='$id' AND day='sunday' AND SET hours='$monday' WHERE id='$id' AND day='monday'";

Query Pulls Out Multiple Rows Even Though Theres Only One
Ive got a query thats selecting info about a product from a table called items and joining on a table called itemimages to get its associated images. The product can have more than one image. If i run the query on an item with 2 images i get 2 results for one item.....when theres only one item.....it seems to duplicate the item for each of its images....

SQL
SELECT items.*, itemimages.* FROM items INNER JOIN itemimages ON (items.itemID = itemimages.itemID) WHERE categoryID = '$category' AND active = 'yes' LIMIT $start, $limit"

Insert Into Single Row Vs Multiple Rows
My question is: is it possible to add data separated by commas into an existing row that already contains some data?

Update Multiple Rows Outside Loop
I know it possible to update rows in loop. But how about outside the loop?
Normally i update in loop like this:

Count Fields Over Multiple Rows
I have a database like this

id, field1,field2,field3,field4,field5

Database contains 100 rows, some rows have no fields filled, some
1field , some 2 fields etc.

How would i count the number of fields filled in total?

So the outcome is (number of fields filled in row1)+(number of fields
filled in row2)+(number of fields filled in
row3)....................+(number of fields filled in row100)

Concatenating Multiple Rows To One Field?
I got a slight problem with a web application, its supposed to several
entries for a certain ID, and display them as one string.

Example:

ID | Name
-------------
1 | Jack
1 | Peter
2 | John
2 | Mark
2 | Ellis

Expected Result for ID 1 should be "Jack, Peter" for example, or "John,
Mark, Ellis" for 2.

Least problem would be clipping off a trainling or leading ",", but the
main problem is a SELECT statement to get them all in one go. Else I'd
have to select every Name per ID, and concatenate them in PHP or
elsewhere. Given its around 100 IDs, I'd have to do like 100 querys to
get the names, *in addition* to the Querys I need before and after.

I want to avoid that, but I couldnt find a simple solution that works
in MySQL 4.1 and above, aswell as it mustn't involve Stored Functions
or something, because I got no access to the mysqld itself, to add the
funcs as modules. Code:

Delete Rows From Multiple Tables
I am writing a simple PHP script to completely remove all references to a user from a whole bunch of tables (the "user" in this case is really a row of data identified by a user_id field within that row).

I tried to use "DELETE FROM * WHERE user_id = $whatever_it_is;" but clearly that would be too easy. What is the proper way to do this?

Add Multiple Rows To An Existing Table?
I have a table named manufacturers, it has one row in right now. I want to upload all of my manufacturers into the table. Is there a way to add multiple rows to the table at the same time? If not, what is a quick way to get about 1,000 manufacturers uploaded into a table?

Delete Rows From Multiple Tables
I have a database containing the folllowing tables;

PUPIL
id ...

ROA
pupil_id ...

MESSAGE
id pupil_id ...

REPLY
message_id ...

How can I delete all the rows from all tables containing the same pupil id and all replies to messages from the same pupil? I managed it using AND clauses in WHERE but if there is no data in say the MESSAGE table then it doesn't work.

Insert Multiple Identical Rows
Is it possible to insert multiple identical rows using a single query without using a loop to build this query. for example:

sqlselected = 0
Set oConn = Server.CreateObject("ADODB.Connection")
oConn.Open "DSN="& websitedsn
oConn.CursorLocation = 3
strSQL = "INSERT INTO testtable (testvar) VALUES ('testinsert') "
oConn.Execute strSQL, sqlselected

I would like to create say 500 of the above rows but not use a loop to build the insert query, and not use a loop to do oRs.addnew or anything like that.. Just a simple 1 line query to add a specific amount of rows. i would eventually like to use a script variable to control how many rows to add.

Update Multiple Rows Within One Table
I have a Dynamically created formfield. Tgis field shows the attached devices off a selected device (for instance you have a pc and in the formfields it shows two attached monitors). The monitors however are in the same database table. (with an other device_id ofcourse). The page with the pc info is shown by using the device_id in the URL.

What I want to do is update some fields in this table for the pc but also for the attached devices....

When I do it like this:

UPDATE dev SET .... etc.
WHERE device_id IN ('#FORM.koppel_2#')

It selects both device id's like this: WHERE dev_volgnr IN ('602,603')
This doesn't work! However in this example the table should be updated for the devices with device_id 602 and 603.

Is this possible? How would I do that?
