MYSQL :: Query To Display The Rows As Colums Is Not Working!!

Shuffle And Display Top X Rows
Using MySQL 4.1.10 with Coldfusion MX 6.1 on top.

A table of data gets regular inserts of hundreds of rows at a time in the same category. A categoryID field (foreign key) is assigned to each row. So the table consists of sequential blocks of data in each category--200 to 1,000 rows of category1 then 200 to 1,000 rows of category2, then some more category 1, and then some category3, etc.

I want to extract a small (and most recent) subset of the data using a select query in a way that shuffles and returns the top rows for each category like this:

Row1 Category1
Row1 Category2
Row1 Category3
Row2 Category1
Row2 Category2
Row2 Category3
Row3 Category1
Row3 Category2
Row3 Category3
Row4 Category1

This example returns 10 rows. I'd like that quantity to be dynamic so I can send the query a variable from CF. The quantity of categories is known (although does grow infrequently) so I can plug that in if necessary but I'm trying to get that quantity on the fly. That, of course, takes a simple count(*) function of the category table. I just can't figure out how to incorporate that with the rest of what is needed.

Am I the only one working this weekend? I think I'm close but I have a maze of nested loops and other CF goofiness and I'm still not there. Hoping to trash all that and find a purer database solution, if possible.

Display 4 Most Recent Rows
I need to display the next 4 upcoming events (from the current date) in our events database...

SELECT * FROM events WHERE eventdate ??? LIMIT 4

Specify A Value For At Least One Of The Colums
i have created a database for a form to hold peoples details who come to my marquee site. i have done most of the entrys as varchar and set null to not null and dont know what to put int he default so left it blank! i have connected to teh db in dreamweaver thts all fine but when i try to insert record i get please specify a value for at least one column.

Sort By 2 Colums As 1
I have 2 tables lets say called: files and notes
files has 2 fileds filname and date_added
notes has 2 fields note subject and date_added

if files had 2 records:
1) file1.pdf : 2007-06-14
2) file2.pdf : 2007-06-17

if files had 2 records:
1) great day out : 2007-06-15
2) why me? : 2007-06-18

i want to sort by the date in both fields but as if they were in 1 fields so output would be
2007-06-14
2007-06-15
2007-06-16
2007-06-17
and not
2007-06-14
2007-06-17
2007-06-15
2007-06-18

Possible To Shift And Splice Colums?
In MYSQL is it possible to shift and splice colums?
say I have a table w/fields: name | tele_num | age
and I get all the addresses later - address initally
stored in a txt type file with 1 rec /line.
I now want: name | address | tel_num | age
Can I do it this? if not can I do:
name | tele_num | age | address ?

Just need the tools cmds to use and the "flow"
you don't have give the actual SQL unless you want.

Show Colums" With A Where
I would need to know if there is a way to filter a Show Columns. The thing is I want to let my customers modify all the fields except the primary key. But since I may not always be the DBA I cannot create the field with the same name. So I need to determine if it's the primary key and if so, I will not show it.
Also I cannot work with views because I will not always be the DBA and also because it would require to create as much views as there will be tables.
So is there a way to inlcude a Where in the statement? If not, is there a command to determine if the field is the primary key?

Query Not Working In 5.0 That Worked In 4.0
I've created a development site for my website that uses mysql 5.0.18 and my live site uses 4.0.16. I have a query I can run without problems on the live site but is giving me errors on the development site and I was hoping someone might know what the problem is. It must be some change to the syntax standard I suppose. Thanks for your help!!!

ANDs In Query Not Working
I am working with this query:

SELECT * FROM reviews WHERE gID = 'nothing' OR gID = '825' OR gID = '864' OR gID = '632' OR gID = '880' OR gID = '839' OR gID = '534' OR gID = '680' OR gID = 'x' AND type = 'online' AND status = '1' ORDER BY RAND() LIMIT 0, 10

With everything going on here, the most important is that only rows with status=1 are selected. However, I am getting some rows with status=0 in my results. Is there something wrong with the ANDs in my query?

Query To Display A Record By Recent Time
Many users uploaded their files to my mysql table through php script,
my table having the details of uploading time, file name, & uploader name.

i need to find the recent uploaded file for all uploaders.

i tried with this query,

select file_name,uploded_by,MAX(date_time) from upload group by uploded_by;

it is giving the recent time, but it is not giving the latest file, it is showing first uploaded file.

Order By Not Working Correctly, Query Problem?
I am using the following query to get a list of anime names and related info from my mysql db. As anime are sometimes known by several names (the actual japanese kantakana/kanji, the romanji translation and the english word). So the info_anime table has all the info about the anime and the info_animename just has the relevent animeid and the name.

The query below is ment to check all the names in info_animename and join them to info_anime.

SQL
SELECT n.*, a.* FROM info_animename AS n, info_anime AS a
WHERE
a.animeid = n.animeid
ORDER BY ".$_GET[orderby]." ".$_GET[order]."

Now all the names are displayed properly with the various info but if you look here:

Live Anime - Anime List

You will see that the names are not in alphabetical order, for the most part they are just anime with several names are not working correctly if you look at the bottom of the page you will see:

Yakusoku no Basho Kumo no Mukou followed by
Beyond The Clouds, The Promised Place

Which are the same anime under different names.

Query Cache Not Working: MySQL 5 / Windows XP
I just installed MySQL 5, and its running great except that the query cache is not working, despite the configuration excerpt from my "my.ini"
below:

query_cache_size=5M
query_cache_limit=2M
query_cache_min_res_unit=4096k
query_cache_type=1

From the MySQL command line, if I enter: SHOW VARIABLES LIKE
'have_query_cache';

I get:
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| have_query_cache | YES |
+------------------+-------+

Also, doing a: SHOW STATUS LIKE 'Qcache%'; gives me:

+-------------------------+---------+
| Variable_name | Value |
+-------------------------+---------+
| Qcache_free_blocks | 1 |
| Qcache_free_memory | 5234168 |
| Qcache_hits | 0 |
| Qcache_inserts | 0 |
| Qcache_lowmem_prunes | 0 |
| Qcache_not_cached | 450 |
| Qcache_queries_in_cache | 0 |
| Qcache_total_blocks | 1 |
+-------------------------+---------+

I figure the "Qcache_free_blocks" and "Qcache_total_blocks" values of 1
are creating the problem; it's basically telling me that there are no
(okay, 1) free blocks to put my query. However, these values never
change.

The query cache is not vital to me, but it does improve performance, and
I'd like to get it going....

Zero Rows Or One Rows Returned, Same Data And Same Query
I have a query that produces a single row (as I expect) when I run it from the mysql client (mysql 4.0.18-Max/linux, also 5.0.19-standard/OSX-intel), or from sqlgrinder (osx, uses jdbc).

When I run it inside my application (a Java app connecting via jdbc), I get zero rows from this query.

I tried it under phpmyadmin, and once again I get zero rows.

Why do I get inconsistent results? Here's the query:

Several Rows From One Query
I've this sql-query...

$sql = "INSERT INTO database (some_kind_of_id, names) VALUES $xxx, $_POST['xxx2']";

The thing is that my post xxx2 are several values that I want inserted on several rows with the values xxx in front...

Last N Rows Of The Query
SELECT expensive query ORDER BY field ASC;
It generates somewhere around 2.9m rows. I want the last 10:

SELECT expensive query ORDER BY field DESC LIMIT 10

But I want them the other way around. Sure, I can do that programatically, but for "application reasons" I want that done in the query, so what I want to do is along the grounds of

SELECT expensive query ORDER BY field LIMIT 10 OFFSET rows()-10
We're using MySQL 4.0. Is there a way to achieve the above without using a temporary table?

SQL Query Not Outputing All Rows.
My query doesn't seem to output all 6 rows in the database only two queries and i'm unsure why. I do know it is the query as when i do
SELECT * FROM case_studies
It outputs all rows.

select programs.program_title,
programs.id, case_studies.id,
case_studies.title, case_studies.author,
case_studies.timestamp from case_studies,
programs WHERE programs.id
= case_studies.id
Any ideas?

I would like to output the data by day pattern. I need some way to determine that in the above table, Mon-Wed is the same, Thu-Fri is the same and Saturday and Sunday are unique.

How Many Rows Were Affected By Query?
How do I retrieve the number of affected rows by an UPDATE query with SQL? The C API exposes mysql_affected_rows() but I can't find documentation of the SQL equivalent...

I'm trying to find if an UPDATE had an effect within a stored procedure, so I can do an INSERT if there's no row to update.

Doing it the other direction to generate an error to act on would be quite wasteful... one INSERT and millions of errors per day.

Eliminate Rows In A Query (without Many OR)
This is my query :

There must be a more efficeint way to find what i want than this :

AND cas.id<>53 AND cas.id<>61 AND cas.id<>173 AND cas.id<>174 AND cas.id<>178 AND cas.id<>185 AND cas.id<>598

Something like cas.id is not (list of values)...

Query With 3.3million Rows Is Slow?
I'm not that great with MySQL...so I was hoping someone could help me out.
The query I'm running is too slow...can anyone tell me what I can do to
speed it up..if I can at all? I was wondering if because ZipListMatrix has
3.3 million rows that 8 seconds is all the faster it's going to be. Any
help is greatly appreciated! I have already "optimized" the tables.

Updating Multiple Rows In One Query

I'v tried that but got a syntax error.

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)

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"

Average Query With 2 Rows From Same Table
My table:
"answer"
answerID
answer(int)
questionID(int)

I want the average of answer1/answer2: AVG(ans1/ans2), but how?

Updating Multiple Rows With Same Fields (in One Query?)
I have 2 tables here

table categories

+--------------------------------------- +
| cat_id | cat_name | cat_total_articles |
+----------------------------------------+
| 1 | PHP | 23 |
+----------------------------------------+
| 2 | MySQL | 17 |
+----------------------------------------+
table articles

+---------------------------- +
| article_id | article_cat_id |
+-----------------------------+
| 1 | 1 |
+-----------------------------+
| 2 | 2 |
+-----------------------------+
Now I've changed an article's category from cat1 to cat2, and I need to update cat_total_articles of both cat1 (minus 1) and cat2 (plus 1) in category table.

Is it possible to combine the following queries into one statement?

PHP

mysql_query("UPDATE categories
SET cat_total_articles = cat_total_articles + 1
WHERE cat_id = 2");

PHP

mysql_query("UPDATE categories
SET cat_total_articles = cat_total_articles - 1
WHERE cat_id = 1");

Help With Updating Duplicate Rows In Mysql Query.
Quote:

SELECT id, count(*) AS numlist FROM products GROUP BY category, name, brands HAVING numlist > 1 ORDER BY id ASC

What it does is find the duplicates. I also have a column called "app" which has a default set to "1". So now what I want to do is that when duplicates are found, I want the first duplicate row in each group to stay as a "1" and the others in the same group to be updated to a "2". I need this done for every group.

How can I do this. I have looked high and low accrossed the web, but can't seem to find any solution.

I have managed to find out how to group them and count the number of listings in each group, but I can't seem to figure out how to do the rest.

Also, if possible, I would like it to be done with one query.

Query Which Gets Rows Based On A Radius, Lon And Lat Doesn't Work?
I have found this query which gets rows based on a radius. I need this for zip codes based on lon and lat's.

$sql2 = "SELECT * FROM table as z WHERE (SQRT( (69.1 * (".$userLat." - z.lat)) * (69.1 * (".$userLat." - z.lat)) + (53.0 *(".$userLong." - z.lon)) * (53.0 *(".$userLong." - z.lon))) <= ".$userRadius." )";
return $sql2;
$res = mysql_query($sql2, $connDB) or die(mysql_error());
$row = mysql_fetch_assoc($res);
based on a test zip code gives a result like

SELECT * FROM table as z WHERE (SQRT( (69.1 * (52.399834 - z.lat)) * (69.1 * (52.399834 - z.lat)) + (53.0 *(4.840762 - z.lon)) * (53.0 *(4.840762 - z.lon))) <= 100 )
the lat and lon of the test zip code are right. As you can see z.lat and z.lon don't get any value. And these would be every lat and lon in table.

In my db table lon and lat are decimal(10,6) type with a default value of 0.000000

Use Where In Query So It Returns Rows That Has Less Than 10 Characters In The Word
I want to return rows that has less than 10 characters in the word that is used in the where clause sort of thing.

I can't really explain so I will give you an example, which is obviously wrong.

What Query To Check If Any Rows Exist Satisfying WHERE Clause?
I'm looking for a query that will check if any rows exists in a table according to a WHERE condition. I know I can use COUNT(*) but then mysql will do unnecessary task of counting all the rows whereas I just need true or false. So far I did this:

SELECT COUNT(*) AS exists FROM mytable WHERE ...
Sometimes I just select the first row and check later in php how many rows have been returned:

SELECT some_col FROM mytable WHERE ... LIMIT 1
But I cannot do this check (or can I?) in sql alone and I have problems when I want to use this in a subquery, for example:

SELECT id,
name,
(SELECT COUNT(*) FROM mytable WHERE ...) AS exists
FROM othertable
WHERE surname='xxx'
Can I do the same without using COUNT(*)? I would like a query that returns 0 or NULL if no rows were found, or 1 (or some other value) if 1 or more rows were found.

Count One Table's Rows From Multi Table Query
here are my tables (condensed)

FEEDS
feed_id
site_id

SITE
site_id
site_name

ARTICLES
article_id
feed_id
link

I want to create a query that returns the total number of articles for every site_id (which is unique in the SITE table). I have this:

PHP

$gsite = mysql_query("SELECT site.site_id, feeds.feed_id, COUNT(articles.article_id) AS acont FROM site,feeds,articles
WHERE feeds.site_id = site.site_id AND articles.feed_id = feeds.feed_id group by site.site_id", $connection)
or die(mysql_error());

The query does not use JOIN, ON and all that good stuff.

I just need the following variables to run through a loop:

site_id
the number of articles rows per site_id

Using A Limit Clause, But Return The Number Of Rows Of The Query Without The Limit
I have heard of a cool feature that mysql provides a way to return the number of rows of an sql statement that contains a LIMIT as if the LIMIT had not been there.

I search the mysql manual, but could not find anything.

How To Get The Total Number Of Rows With A Query "limit" ?
I would like to paginate the results of a query on several pages. So I
use a query with a limit X offset Y to display X results on a page,
ok.

But for the first page, I need to run the same query with a count(*)
to know how many pages I will get (number total of rows/ X).

The problem is my query is very slow (maybe 5s) because there is much
worch to do, and on the first page, I need to run this query twice
(not exactly, but ...) so the page is very very slow to load.

My question is : is there a function to get the total number of rows
even on a query with "limit" ? Or what could I do else?

How To Insert Multiple Rows With 1 Insert Query
I am having a form on the front end which has for example 3 rows each with 3 columns. The user enters data in all the 3 rows. When he hits the add button these should get in the database. What insert query would I write to add all of them together to the database? Do I need to use some procedure?
