select rows based on equal columns values - sql

consider we have a table with this columns
Id
fk_newsId
fk_NewsGroupId
fk_NewsZoneId
I need to select all records with same fk_NewsGroup and fk_NewsZone
something like this
+----+-----------+--------------+-------------+
| Id | fk_NewsId | fk_NewsGroup | fk_NewsZone |
+----+-----------+--------------+-------------+
| 1 | 60 | 5 | 8 |
| 2 | 30 | 5 | 8 |
| 3 | 31 | 9 | 20 |
| 4 | 5 | 9 | 20 |
| 5 | 12 | 9 | 20 |
| 6 | 1000 | 20 | 11 |
| 7 | 21 | 20 | 11 |
| 8 | 6 | 20 | 11 |
+----+-----------+--------------+-------------+
how can do that?
I tride group by like this
but it dosnt give desired output
select fk_NewsId, fk_NewsGroup,fk_NewsZone from tbl_test
group by fk_NewsGroup,fk_NewsZone,fk_NewsId

You can try to use COUNT with window function, to get the count by fk_NewsGroup and fk_NewsZone columns.
then get count greater than one.
SELECT *
FROM (
SELECT *,COUNT(*) OVER(PARTITION BY fk_NewsGroup,fk_NewsZone ORDER BY fk_NewsZone) cnt
FROM tbl_test
)t1
where t1.cnt > 1
dbfiddle

Not absolutely clear as to what you mean, but something like so:
SELECT t.Id, t.fk_NewsId, t.fk_NewsGroup, t.fk_NewsZone FROM tbl_test t
INNER JOIN (
SELECT fk_NewsGroup,fk_NewsZone, COUNT(*) AS Counted FROM tbl_test
GROUP BY fk_NewsGroup,fk_NewsZone
HAVING COUNT(*) > 1) g
ON t.fk_NewsGroup = g.fk_NewsGroup
AND t.fk_NewsZone = g.fk_NewsZone
DBFiddle example

I would use Group by and do it like:
select max(id) as Id, Max(fk_NewsId) as fk_NewsId, fk_NewsGroup,fk_NewsZone from #temp
group by fk_NewsGroup,fk_NewsZone

Query to get the count of data for particular customer with all other data from table

My table structure is as follows:
group_id | cust_id | ticket_num
------------------------------
60 | 12 | 1
60 | 12 | 2
60 | 12 | 3
60 | 12 | 4
60 | 30 | 5
60 | 30 | 6
60 | 31 | 7
60 | 31 | 8
65 | 02 | 1
I want to fetch all the data for group_id=60 and find the count of ticket_num for each customer in that group. My output should be like this:
cust_id | ticket_count | ticket_num
------------------------------
12 | 4 | 1
12 | | 2
12 | | 3
12 | | 4
30 | 2 | 5
30 | | 6
31 | 2 | 7
31 | | 8
I tried this query:
SELECT gd.cust_id, Count(gd.cust_id),gd.ticket_num
FROM Group_details gd
WHERE gd.group_id = 65
GROUP BY gd.cust_id;
But this query is not working.
You appear to want the ANSI/ISO standard row_number() functions and count() as a window function:
select gd.cust_id, count(*) over (partition by gd.cust_id) as num_tickets,
row_number() over (order by gd.cust_id) as ticket_seqnum
from group_details gd
where gd.group_id = 60;
use aggregate and subquery
select t2.*,t1.ticket_num from Group_details t1
inner join
(
SELECT gd.cust_id, Count(gd.ticket_num) as ticket_count
FROM Group_details gd where gd.group_id = 60
GROUP BY gd.cust_id
) t2 on t1.cust_id=t2.cust_id

Grouping counts into overlapping categories

I'm looking to group counts into categories of (0+, 5+, 10+, 15+, etc.)
So an agent with 7 leads should be counted in the 0+, 5+ groups, but not 10+, 15+.
Postgres Query:
WITH agent_stats AS (
SELECT agent_id, FLOOR(COUNT(*)/5) AS count_category
FROM leads
GROUP BY 1
)
SELECT count_category, COUNT(*)
FROM agent_stats
GROUP BY 1
ORDER BY 1
Result:
| count_category | count |
| 0 | 12 |
| 5 | 18 |
| 15 | 9 |
| 20 | 4 |
Desired:
| count_category | count |
| 0 | 43 |
| 5 | 31 |
| 15 | 13 |
| 20 | 4 |
The simplest way is probably a cumulative sum:
WITH agent_stats AS (
SELECT agent_id, FLOOR(COUNT(*)/5) AS count_category
FROM leads
GROUP BY 1
)
SELECT count_category, COUNT(*),
SUM(COUNT(*)) OVER (ORDER BY count_category DESC)
FROM agent_stats
GROUP BY 1
ORDER BY 1;

SQL - summing up minutes in the table for all the rows with the same month as their date and store it in a column for each row

I have a table as follow:
id |minutes |sumOfMinutes|Date
_______________________________________
1 | 5 | | 20141106
1 | 7 | | 20141106
2 | 1 | | 20141106
2 | 9 | | 20141106
3 | 8 | | 20141106
How can I store sum of minutes in the third column for rows under the same month, so that i have:
id |minutes |sumOfMinutes| Date
_____________________________________
1 | 5 | 12 | 20141106
1 | 7 | 12 | 20141112
2 | 1 | 18 | 20141006
2 | 9 | 18 | 20141007
3 | 8 | 18 | 20141009
Use SUM() and Group by
SELECT table1.id, table1.minutes, SUM(monthTot.minutes), table1.Date
FROM table 1
JOIN table1 AS monthTot ON
MONTH(monthTot.date) = MONTH(table1.date)
GROUP BY table1.id, table1.minutes, table1.Date
sum with partition by option can be used to achieve this.
select id, [minutes],
sum([minutes]) over ( partition by month([date]) ) as sumOfMinutes,
[Date]
from Table1

sql - select row from group based on multiple values

I have a table like:
| ID | Val |
+-------+-----+
| abc-1 | 10 |
| abc-2 | 30 |
| cde-1 | 10 |
| cde-2 | 10 |
| efg-1 | 20 |
| efg-2 | 11 |
and would like to get the result based on the substring(ID, 1, 3) and minimum value and ist must be only the first in case the Val has duplicates
| ID | Val |
+-------+-----+
| abc-1 | 10 |
| cde-1 | 10 |
| efg-2 | 11 |
the problem is that I am stuck, because I cannot use group by substring(id,1,3), ID since it will then have again 2 rows (each for abc-1 and abc-2)
WITH
sorted
AS
(
SELECT
*,
ROW_NUMBER() OVER (PARTITION BY substring(id,1,3) ORDER BY val, id) AS sequence_id
FROM
yourTable
)
SELECT
*
FROM
sorted
WHERE
sequence_id = 1
SELECT SUBSTRING(id,1,3),MIN(val) FROM Table1 GROUP BY SUBSTRING(id,1,3);
You were grouping the columns using both SUBSTRING(id,1,3),id instead of just SUBSTRING(id,1,3). It works perfectly fine.Check the same example in this below link.

select the most recent in all groups of with the same value in one column

The question isn't very clear, but I'll illustrate what I mean, suppose my table is like such:
item_name | date added | val1 | val2
------------------------------------
1 | date+1 | 10 | 20
1 | date | 12 | 21
2 | date+1 | 5 | 6
3 | date+3 | 3 | 1
3 | date+2 | 5 | 2
3 | date | 3 | 1
And I want to select row 1, 3, 4 as they are the most recent entries for each item
Try this:
select *
from tableX t1
where t1.date_added = (select max(t2.date_added)
from tableX t2
where t2.item_name = t1.item_name )
