I've got a problem with two mysql tables. I've done some code and I think I am close to the solution, but I'm not sure if this is right.
So here are the two tables:
Table 1: Blogs
Columns: ID, agp_name, agp_url, agp_username, agp_password
Table 2: Keywords
Columns: ID, agp_user_id, agp_order_id, agp_blog_id, agp_keywords, agp_keywords_date
What I want is to get one random row from Table1 based on the following condition: if the agp_keyword match one of the keywords in the last 5 days then do not include into the result.
So far I did this:
SELECT
t1.agp_user_id, t1.agp_order_id, t1.agp_blog_id, t1.agp_keywords, t1.agp_keywords_date, t2.agp_name, t2.agp_url, t2.agp_username, t2.agp_password
FROM table1 AS t1
INNER JOIN (
SELECT ID, agp_name, agp_url, agp_username, agp_password, agp_blogposts
FROM table2
) AS t2 ON t1.agp_blog_id = t2.ID
WHERE
t1.agp_keywords NOT LIKE "%keyword1%" AND
t1.agp_keywords NOT LIKE "%keyword2%" AND
t1.agp_keywords_date BETWEEN (1369440000 AND 1369932432)
ORDER BY RAND() LIMIT 1
However this does not work correctly. Any help will be appreciated.
Try this, your original specifications were a bit confusing :(
SELECT keywords.agp_user_id,
keywords.agp_order_id,
keywords.agp_blog_id,
keywords.agp_keywords,
keywords.agp_keywords_date,
blogs.agp_name,
blogs.agp_url,
blogs.agp_username,
blogs.agp_password
FROM blogs
LEFT JOIN keywords
ON keywords.agp_blog_id = blogs.ID
AND keywords.agp_keywords NOT LIKE "%keyword1%"
AND keywords.agp_keywords NOT LIKE "%keyword2%"
AND FROM_UNIXTIME(keywords.agp_keywords_date) > (DATE_SUB(CURDATE(), INTERVAL 5 DAYS))
ORDER BY RAND() LIMIT 1

Afternoon folks,
I have had a good dig around and can't find the answer, so a good time to ask!
I'd like to select random rows from one table and then join into this random rows from another table where the ID that I have is the same. It would also be great to only select where I have an entry in the second table. I have tried all manner of sub-queries but am getting a bit lost. An inner join as read will do it but again with the randomness of it all!! Grrr...
SELECT
tracks.track_id,
cuttings.square_cutting,
cuttings.cutting_2,
cuttings.cutting_3,
cuttings.blog_text
FROM tbl_tracks tracks,
(SELECT
square_cutting,
cutting_2,
cutting_3,
blog_text
FROM
tbl_cuttings
WHERE track_id = tracks.track_id <-- wont find it, obviously!!
ORDER BY RAND()
LIMIT 1) cuttings
WHERE tracks.active = '1' ORDER BY RAND()
Thanks in advance for any help.
So:
I'd like random tracks showing
track id -> with random cuttings, of which there can be many but I just want 1.
It would then be ideal to only show a result if there is a cutting associated with that track.
Hope that helps.
I'm now trying to go a step further with this and order this by a RAND() seed as I'm now having to add in pagination. Only problem is that its not giving me back the same random list due to a given seed. Any Ideas?
SELECT
tracks.track_id,
cuttings.square_cutting,
cuttings.cutting_2,
cuttings.cutting_3,
cuttings.blog_text
FROM tbl_tracks tracks
INNER JOIN
(SELECT track_id,
square_cutting,
cutting_2,
cutting_3,
blog_text
FROM
tbl_cuttings
ORDER BY RAND()) cuttings ON tracks.track_id = cuttings.track_id
WHERE tracks.active = '1'
ORDER BY RAND(1)
LIMIT 0,4;
you could use an inner join
SELECT
tracks.track_id,
cuttings.square_cutting,
cuttings.cutting_2,
cuttings.cutting_3,
cuttings.blog_text
FROM tbl_tracks tracks
INNER JOIN
(SELECT track_id,
square_cutting,
cutting_2,
cutting_3,
blog_text
FROM
tbl_cuttings
ORDER BY RAND()
LIMIT 1) cuttings on cuttings.track_id = tracks.track_id
WHERE tracks.active = '1'
ORDER BY RAND()
I am running this query, and I am getting ** #1241 - Operand should contain 1 column(s)** error:
SELECT `forumCategories`.`id`, `forumCategories`.`name`, `forumCategories`.`order`, `forumCategories`.`description`, `forumCategories`.`date_created`, COUNT(forumPosts.forumCategory_id) as postCount,
(SELECT `forumPosts`.*, `forumChildPosts`.`id`, `forumChildPosts`.`forumPost_id`, COUNT(forumChildPosts.forumPost_id) as childCount FROM `forumChildPosts` LEFT JOIN `forumPosts` ON `forumPosts`.`id` = `forumChildPosts`.`forumPost_id` GROUP BY `forumPosts`.`id`) AS childCount
FROM `forumCategories`
LEFT JOIN `forumPosts` ON `forumCategories`.`id` = `forumPosts`.`forumCategory_id`
GROUP BY `forumCategories`.`id`
ORDER BY `forumCategories`.`order` DESC
I have 3 tables:
forumCategories
forumPosts | forumPosts.forumCategory_id = forumCategories.id
forumChildPosts | forumChildPosts.forumPosts_id = forumPosts.id
I want to count all posts for the forum category, and them I want to count all the child posts that belongs to that forum category. How can I do this?
You can't select several items with a subselect and then give them one name. Now you're getting everything from forumPosts, something from forumChildPosts etc and trying to put that into a single column, childCount. This is not allowed.
It might be enough to remove all other result columns from that select and only leave the count?
I couldn't try it, is that makes sense ? But you can't get nested results from mysql due to its limitation, MYSQL is a Matrix table.
SELECT `forumCategories`.`id`,
`forumCategories`.`name`,
`forumCategories`.`order`,
`forumCategories`.`description`,
`forumCategories`.`date_created`,
COUNT(forumPosts.forumCategory_id) AS postCount,
(SELECT COUNT(forumChildPosts.forumPost_id) AS childCount FROM `forumChildPosts` LEFT JOIN `forumPosts` ON `forumPosts`.`id` = `forumChildPosts`.`forumPost_id` GROUP BY `forumPosts`.`id`) AS childCount
FROM `forumCategories`
LEFT JOIN `forumPosts` ON `forumCategories`.`id` = `forumPosts`.`forumCategory_id`
GROUP BY `forumCategories`.`id`
ORDER BY `forumCategories`.`order` DESC
I would like to seek some help in my query...i want to do is if specific atic and oaic is empty in the table...the interview_sum or other_sum to that specific atic oaic should be empty too....can anyone know how to do that?
picture of current output:
current query: my query still gives numbers to other_sum or interview_sum even its empty.
SELECT DISTINCT
IF(t.inttotal=NULL,0,(SELECT SUM(t2.inttotal)
FROM app_interview2 AS t2
WHERE t2.atic = t.atic AND t2.inttotal>0)/7)
AS interview_sum,
IF(o.ototal=NULL,0,(SELECT SUM(o2.ototal)
FROM other_app2 AS o2
WHERE o2.oaic = o.oaic AND o2.ototal>0)/7)
AS other_sum,
atid,
atic,
atname,
region,
town,
uniq_id,
position,
salary_grade,
salary
FROM app_interview2 AS t, other_app2 AS o
GROUP BY t.atname HAVING COUNT(DISTINCT t.atic)
I made a few assumptions:
You probably have a table that app_interview2.atic and other_app2.oaic are the foreign keys of, but since you did not share it, I derived a table in the FROM clause.
This assumes atname is always the same for atid.
You are also dividing by 7 - which I assume is to get the average, so I used the AVG function.
Solution---
SELECT t1.id AS atid
,interview.atname AS atname
,COALESCE(interview.interviewsum, 0) AS interviewsum
,COALESCE(interview.interviewavg,0) AS interviewavg
,COALESCE(other.othersum, 0) AS othersum
,COALESCE(other.otheravg) AS otheravg
FROM (SELECT DISTINCT atid AS id
FROM app_interview2
UNION
SELECT DISTINCT oaic
FROM other_app2) AS t1
LEFT JOIN (SELECT atid, atname, SUM(inttotal) AS interviewsum, AVG(inttotal) AS interviewavg
FROM app_interview2
GROUP BY atid, atname) as interview
ON interview.atid = t1.id
LEFT JOIN (SELECT oaic, SUM(ototal) AS othersum, AVG(ototal) AS otheravg
FROM other_app2
GROUP BY oaic) AS other
ON other.oaic = t1.id;
--
If this gives the results your were hoping for, I would replace the t1 derived table in the FROM clause with the table whose primary key I described above AND probably has those columns (e.g., region, town, etc) that I did not include
How can I select one row from that table http://i.stack.imgur.com/27cu9.jpg where values of 'user_1' and 'user_2' may look like
user_1 user_2
1 2
2 1
In other words I want to select a field that contains 2 users with submitted=1 no matter in which field the value is.
Here is a simple query that does this:
select *
from t
where submitted = 1 and 2 in (user_1, user_2)
If I understood your question, I think you need to JOIN the table on itself if you are trying to return rows that have corresponding users (1,2) and (2,1):
select t1.*
from yourtable t1
join yourtable t2 on
t1.user_1 = t2.user_2 and t1.user_2 = t2.user_1
SQL Fiddle Demo
If however you are just trying to see if user 2 exists in either of the fields, then look at Gordon's post.
Use this:-
select * from tblname as t1, tblname as t2 where
t1.user_1 = t2.user_2 and t1.user_2 = t2.user_1 and t1.user_1<>t1.user_2
EDIT:-
Updated the query so that the rows with the same values do not appear in the result.
Hi I have a table like this
ID UserName
1 test#test.com
2 test#test.com
3 john#stack.com
4 test#test.com
5 adam#stack.com
6 john#stack.com
I need an output like this. I need only repeated rows list. How can I create this kind of an output using mysql query.
ID UserName Count
1 test#test.com 3
2 john#stack.com 2
Please help me.
Thanks.
I had the same problem some time ago and solved it like this (as far as I remember):
SELECT *
FROM tableA INNER JOIN
(SELECT DISTINCT MAX(id) as id, type_id, temp FROM tableA GROUP BY type_id, temp) AS t
ON tableA.id = t.id
AND tableA.type_id = t.type_id
AND tableA.temp = t.temp
You join the table with itself selecting the ids that are duplicate. The fields that should be tested against duplicate values are in this case type_id and temp. If you need more or less fields that should be considered as duplicates you can adjust the fields.
I don't know if this helps in your case and if it can be done in a more simple way, so I'm prepared for downvotes ;-)
Edit: removed last condition AND tableA.id < t.id as suggested by ypercube because it leads to 0 results.
It looks like you're trying to pull the following data:
First ID for a given UserName
The UserName itself
The total number of IDs for that UserName
This query should do the trick:
SELECT
MIN(id),
UserName,
COUNT(id)
FROM users
GROUP BY UserName;
since the ID is not unique so its a bit not logical to get the sum of unique UserName from the table.
If the ID is not required we can get the result from single query.
SELECT UserName, COUNT(UserName) AS Count
FROM TableName GROUP BY UserName
HAVING COUNT(UserName) > 1;
But in the case of ID in the result it will be a more complicated query including sub-query and inner table.
SELECT UserName
, COUNT(*) AS `Count`
FROM tableX
GROUP BY UserName
HAVING COUNT(*) > 1
Hi this is the right answer.
SELECT UserName, COUNT(UserName) AS Count
FROM TableName GROUP BY UserName
HAVING COUNT(UserName) > 1;
