I have a table with 3 columns X, Date and Qtr as attached.
I need to get an output as mentioned in attachment (data taken only for 8 quarters)
create table mQtr
( X varchar(5), XDate date, Qtr int);
insert into mQtr
values ('X1', '2011-11-01', 4), ('X2', '2011-10-01', 4),
('X3', '2011-09-01', 3), ('X4', '2011-08-01', 3),
('X5', '2011-07-01', 3), ('X6', '2011-06-01', 2),
('X7','2011-05-01',2), ('X8','2011-04-01',2),
('X9','2011-03-01',1), ('X10','2011-02-01',1),
('X11','2011-01-01',1), ('X12','2010-12-01',4),
('X13','2010-11-01',4), ('X14','2010-10-01',4),
('X15','2010-09-01',3), ('X16','2010-08-01',3),
('X17','2010-07-01',3), ('X18','2010-06-01',2),
('X19','2010-05-01',2), ('X20','2010-04-01',2),
('X21','2010-03-01',1), ('X22','2010-02-01',1),
('X23','2010-01-01',1), ('X24','2009-12-01',4)
What I am expecting the following result set based on Qtr value, I would like to generate sum of X values. Output should be some like this:
Qtr mOutput
----------------
1 x1+x2
2 x3+x4+x5
3 x6+x7+x8
4 x9+x10+x11
5 x12+x13+x14
6 x15+x16+x17
7 x18+x19+x20
8 x21+x22+x23
Please help me to frame the query.
Thanks,

You can use JOIN and GROUP BY with HAVING count(*) = 3 in statement. This Link can be useful

Im trying to do some calculations using postgres, but no sucess so far. My query goes something like this:
select ....,
(select json_agg(data_table)
from (..... HERE GOES DE RESULT OF THE CALCULATION + a lot of business and data.... ) as data_table)
from foo
So i gonna exemplify with a table:
create temp table tbdata (id smallint, parent_id smallint, value numeric(25,2));
insert into tbdata values(1, null, 100), (2, 1, 50), (3, 1, 49), (4, 3, 20), (5, 3, 29);
select * from tbdata;
I need to calculate the difference between the sum of the siblings and the parent value. Example:
ID 2(50) + ID 3(49) = 99
ID 1(parent) = 100
so i need to add 1 to any of the childs (lets say 3), the result gonna be:
ID 2(50) + ID 3(49 + 1) = 100
ID 1(parent) = 100
After that, my ID3 have changed, so i need to update any of his childs:
ID 4(20) + ID 5(29) = 49
ID 3(parent) = 50
then again, updating value of ID 5 with the difference (50 - 49)
ID 4(20) + ID 5(29 + 1) = 50
ID 3(parent) = 50
I tried using recursive queries, windows function, and cte, but i always stuck in something. I was able to do using a function with a loop, but i dont want to do that.
Theres any way i can do it with a single SQL?
I have a table which has has a column that i need to take the average but in my average i want to exclude minues numbers
im sure this im doing is wrong,but how can i do it?
SELECT power_curve_quality where m_turbine_id='192.168.30.82'
and m_date>='2020-08-01' and m_date<'2020-09-01'
FROM wh.t_statistics_daily_ext
EXCEPT select power_curve_quality<0
FROM wh.t_statistics_daily_ext
where m_turbine_id='192.168.30.82' and m_date>='2020-08-01' and m_date<'2020-09-01'
If you want the negative observations in the divisor, then this will do it:
select avg(greatest(power_curve_quality, 0))
from t_statistics_daily_ext
where . . .
If you want to exclude negative observations altogether, then use this:
select avg(power_curve_quality)
from t_statistics_daily_ext
where . . .
and power_curve_quality >= 0
Something like:
create table avg(id int, fld_1 int);
insert into avg values(1, 2), (2, -1), (3, 4), (4, -4), (5, 3);
select avg(fld_1) from avg where fld_1 >= 0;
Just add power_curve_quality >= 0 into the WHERE clause like so:
SELECT
avg(power_curve_quality)
FROM
t_statistics_daily_ext
WHERE
power_curve_quality >= 0
and m_turbine_id = '192.168.30.82'
and m_date >= '2020-08-01'
and m_date < '2020-09-01'
;
Have a table where one of the columns has all of the info I need for a report.
I want to substring certain portions of this column as a column in this report, but the problem is that this column has results from 3 varying character lengths.
Example:
Row1: 20180101_ABC_12
Row2: 20180102_DEFG_23
Row3: 20180103_HIJKL_45
In this particular example I want the middle portion (eg. ABC) to be a column called 'Initials', problem is I am using CASE logic for each LEN. Not sure else how to achieve this.
My sample query below. It pulls all of the possible options, but as separate columns. What would I need to do to have these 3 options pull into one column, let's call it 'Initials'?
Thanks
SELECT
FileName
, CASE WHEN LEN(FileName) = 10 THEN SUBSTRING(FileName, 10, 3) ELSE NULL END
, CASE WHEN LEN(FileName) = 11 THEN SUBSTRING(FileName, 10, 4) ELSE NULL END
, CASE WHEN LEN(FileName) = 12 THEN SUBSTRING(FileName, 10, 5) ELSE NULL END
FROM File
In Tableau, you would accomplish this using a calculated field.
Initials:
CASE LEN(FileName)
WHEN 10 THEN SUBSTRING(FileName, 10, 3)
WHEN 11 THEN SUBSTRING(FileName, 10, 4)
WHEN 12 THEN SUBSTRING(FileName, 10, 5)
END
Or maybe
SUBSTRING(FileName
,10
,CASE LEN(FileName)
WHEN 10 THEN 3
WHEN 11 THEN 4
WHEN 12 THEN 5
END
)
But barring the more technical aspect, this can be solved with math (assuming your data is either limited to the 10, 11, and 12, or that the pattern holds):
SUBSTRING(FileName
,10
,LEN(FileName)-7
)
You need 1 CASE statement covering every possible case and not 3 separate ones, because each one creates a new column:
SELECT
FileName
, CASE LEN(FileName)
WHEN 10 THEN SUBSTRING(FileName, 10, 3)
WHEN 11 THEN SUBSTRING(FileName, 10, 4)
WHEN 12 THEN SUBSTRING(FileName, 10, 5)
ELSE NULL
END AS Initials
FROM File
Another way to get everything between the 2 _:
SELECT
FileName
, substring(
left(FileName, len(FileName) - charindex('_', reverse(FileName) + '_')),
charindex('_', FileName) + 1,
len(FileName)
) AS Initials
FROM File
but from your logic I assume that the values in column FileName have the same patern:
<9 digits>_<Initials>_<2 digits>
If this is the case then you can get what you want like this:
SELECT
FileName
, substring(FileName, 10, len(FileName) - 12) AS Initials
FROM File
I have been having fun with an issue where I need to break apart a string in SQL Server 2012 and test for values it may or may not contain. The values, when present, will be separated by up to two different ; symbols.
When there is nothing, it will be blank.
When there is a single value, it will show up without the delimiter.
When there are two or more, up to 3, they will be separated by the delimiter.
As I said, if there is nothing in the record, it will be blank. Below are some example of how the data may come across:
' ',
'1',
'24',
'15;1;24',
'10;1;22',
'5;1;7',
'12;1',
'10;12',
'1;5',
'1;1;1',
'15;20;22'
I have searched the forums and found many clues, but I have not been able to come up with a total solution given all potential data values. Essentially, I would like to break it into 3 separate values.
text before the first delimiter or in the absence of the delimiter, just the text.
Text after the first delimiter and before the second in situation where there are two delimiters.
The following has worked consistently:
substring(SUBSTRING(Food_Desc, charindex(';', Food_Desc) + 1, 4), 0,
charindex(';', SUBSTRING(Food_Desc, charindex(';', Food_Desc) + 1, 4))) as [Middle]
Text after the second delimiter in the even there are two delimiters and there is a third value
The main challenge is the fact that the delimiter, when present, moves depending on the value in the table. values 1-9 make it show up as the second character in the string, values 10-24 make it show up as the 3rd, etc.
Any help would be greatly appreciated.
This is simple if you have a well written t-sql splitter function. For this solution I'm using Jeff Moden's delimitedsplit8k.
sample data and solution
DECLARE #table table (someid int identity, sometext varchar(100));
INSERT #table VALUES (' '),('1'),('24'),('15;1;24'),('10;1;22'),
('5;1;7'),('12;1'),('10;12'),('1;5'),('1;1;1'),('15;20;22');
SELECT
someid,
sometext,
ItemNumber,
Item
FROM #table
CROSS APPLY dbo.DelimitedSplit8K_LEAD(sometext, ';');
results
someid sometext ItemNumber Item
----------- ----------------- ----------- --------
1 1
2 1 1 1
3 24 1 24
4 15;1;24 1 15
4 15;1;24 2 1

Below is a modified version of a similar question How do I split a string so I can access item x?. Changing the text value for #sample to each of your possibilities listed seemed to work for me.
DECLARE #sample VARCHAR(200) = '15;20;22';
DECLARE #individual VARCHAR(20) = NULL;
WHILE LEN(#sample) > 0
BEGIN
IF PATINDEX('%;%', #sample) > 0
BEGIN
SET #individual = SUBSTRING(#sample, 0, PATINDEX('%;%', #sample));
SELECT #individual;
SET #sample = SUBSTRING(#sample, LEN(#individual + ';') + 1, LEN(#sample));
END;
ELSE
BEGIN
SET #individual = #sample;
SET #sample = NULL;
SELECT #individual;
END;
END;
I am getting a tad frustrated and was wondering if you can help:
I have a Pitch Values Table with the following Columns PitchValues_Skey, PitchType_Skey (this is a foreign key), Start Date, End Date and finally value:
For Example:
1 7 01/01/2010 31/12/2010 £15
2 7 01/01/2011 31/12/2011 £20
And all I want to do is update my Bookings table with how much each booking is going to be, so I put together the code below which worked fine when I only had 2010 data, but I know have 2011 and 2012 and want to update it but it will only update with the 2010 prices.
SELECT Bookings.Booking_Skey, DATEDIFF(day, Bookings.ArrivalDate, Bookings.DepartureDate) * PitchValues.Value AS BookingValue,
PitchValues.PitchType_Skey
FROM Bookings INNER JOIN
PitchValues ON Bookings.PitchType_Skey = PitchValues.PitchType_Skey
WHERE (Bookings.Booking_Skey = 1)
So when I run the query above I would expect to see one line of data but instead I see 4 (See Below)
I would expect this:
Booking_Skey BookingValue PitchType_Skey
1 420 4
But I get this
Booking_Skey BookingValue PitchType_Skey
1 420 4
1 453.6 4
1 476.7 4
1 476.7 4
All sorted now, thanks for your help.
SELECT Bookings.Booking_Skey, DATEDIFF(DAY, Bookings.ArrivalDate, Bookings.DepartureDate) * PitchValues.Value AS BookingValue, PitchValues.PitchType_Skey
FROM Bookings
INNER JOIN PitchValues ON Bookings.PitchType_Skey = PitchValues.PitchType_Skey
AND Bookings.ArrivalDate BETWEEN PitchValues.StartDate AND PitchValues.EndDate
WHERE (Bookings.Booking_Skey = 1)
