Can anyone help?
What is the MySQL query to get
id | number | member | date
11 | 133 | John | 2020-02-05
9 | 450 | Jason | 2020-02-07
6 | 10 | Luna | 2020-02-08
from
id | number | member | date
1 | 133 | John | 2020-02-05
2 | 456 | Carl | 2020-02-07
3 | 450 | Jason | 2020-02-07
4 | 5 | Kaiser | 2020-02-08
5 | 5 | Liliana| 2020-02-08
6 | 10 | Luna | 2020-02-08
7 | 20 | Liliana| 2020-02-09
8 | 20 | Luna | 2020-02-09
where, for each date, it'll select the row with the minimum but the unique number, if it exists.

I have a table called visits where concat(s_id, c_id) is unique and id is the primary key. s_id is the ID number of a website and c_id is a campaign ID number. I want to show all the hits each campaign is getting and group by the site. I want each site on a single row
+-----+------+------+------+
| id | s_id | c_id | hits |
+-----+------+------+------+
| 1 | 13 | 8 | 245 |
| 2 | 13 | 8 | 458 |
| 3 | 13 | 3 | 27 |
| 4 | 13 | 4 | 193 |
| 5 | 14 | 1 | 320 |
| 6 | 14 | 1 | 183 |
| 7 | 14 | 3 | 783 |
| 8 | 14 | 4 | 226 |
| 9 | 5 | 8 | 671 |
| 10 | 5 | 8 | 914 |
| 11 | 5 | 3 | 548 |
| 12 | 5 | 4 | 832 |
| 13 | 22 | 8 | 84 |
| 14 | 22 | 1 | 7 |
| 15 | 22 | 3 | 796 |
| 16 | 22 | 4 | 0 |

I would like to have the following result set:
s_id | hits | hits | hits| hits
13 | 245 | 458 | 27 | 193
14 | 320 | 183 | 783 | 226
5 | 671 | 914 | 548 | 832
22 | 84 | 7 | 796 | 0
Here is what I have tried which does not pull all the hits columns back.
SELECT v.*, v2.* FROM visits v
INNER JOIN visits v2 on v.s_id = v2.s_id
GROUP BY s_id
How can I get multiple rows into columns?
If your'e data set is not crazy huge and you are just trying to get the multiple rows as a single row.... one way to do this...
SELECT
s_id,
GROUP_CONCAT(hits SEPARATOR ',') as hits_list
FROM
visits
GROUP BY s_id
Since it doesn't use any joins or subqueries etc, i find this way to be quite fast.
you can later split/explode the data based on the ',' separator in PHP or whatever language you are using.
$hits = explode($hits_list, ','); //get them in an array
My table is as follow:
-------------------------------------------
| rec_id | A_id | B_id |Date(YYYY-MM-DD)|
-------------------------------------------
| 1 | 1 | 6 | 2014-01-01 |
| 2 | 5 | 1 | 2014-01-02 |
| 3 | 2 | 6 | 2015-01-03 |
| 4 | 6 | 1 | 2014-01-04 |
| 5 | 7 | 1 | 2014-01-05 |
| 6 | 3 | 6 | 2014-01-06 |
| 7 | 8 | 1 | 2014-01-07 |
| 8 | 4 | 6 | 2014-01-08 |
| 9 | 9 | 1 | 2014-01-09 |
| 10 | 10 | 21 | 2014-01-10 |
| 11 | 12 | 21 | 2014-01-11 |
| 12 | 11 | 2 | 2014-01-12 |
| 13 | 1 | 1 | 2014-12-31 |
| 14 | 2 | 2 | 2014-12-31 |
| 15 | 1 | 1 | 2015-01-31 |
| 16 | 10 | 21 | 2015-01-31 |
| 17 | 1 | 21 | 2014-10-31 |
This table represents the possession of various "A_id" to a specific "B_id" with a date when it is possessed. The possession of each "A_id" can be changed later on at any time. That means the only the latest possession is considered.
I want to find out all the "A_id" that are currently (possessed in latest date) in possession of a specific "B_id". For example, for "B_id" = 6 the possessed "A_id" at present are as follows:
---------------------------
| A_id | Date(YYYY-MM-DD) |
---------------------------
| 2 | 2015-01-03 |
| 3 | 2014-01-06 |
| 4 | 2014-01-08 |
Similarly, for "B_id" = 21 the possessed "A_id" at present are as follows:
---------------------------
| A_id | Date(YYYY-MM-DD) |
---------------------------
| 10 | 2015-01-31 |
| 12 | 2014-01-11 |
I would highly appreciate your kind help in this regard.
One way to accomplish this is to use a correlated not exists predicate that makes sure that there doesn't exists any later possession for each A_ID with another B_ID.
SELECT A_ID, MAX(PDATE) AS DATE
FROM YOUR_TABLE T
WHERE B_ID = 6
AND NOT EXISTS (
SELECT 1
FROM YOUR_TABLE
WHERE A_ID = T.A_ID
AND PDATE > T.PDATE
AND B_ID <> T.B_ID
)
GROUP BY A_ID

The following less than date query does not works
select * from USER_POINTS_MAPPING where 'date' < '2015-03-17';
But when I do
select * from USER_POINTS_MAPPING where 'date' > '2015-03-17';
It throws back all the rows. What is this happening?
Try without ' characters (single quotation mark) around date. In MySQL either don't use any quotation mark or use this one ` (backtick) around field names.
'date' means date as string. And 'date' is always greater than '2015-03-17' when they are compared as string
While
`date`
means date as a field name
So the correct query is:
select * from USER_POINTS_MAPPING where date < '2015-03-17';
Pro tip: Don't use date as a column name. It's a reserved word. If you must use it surround it with backticks, not quotes.
where `data` < '2015-03-17'
I have 3 tables in my db, the scenario is inventory is entered into the database with reference to invoice no/po number, then users request for inventory and admin assign the items from specific invoices_items/po_items.
