I'm in new this field. How do I manage the dynamic calculation with formulas and what steps to achieve the below output?.
I have tables.
Table 1 - Info_question table is for details about questions name and id.
q_id
questions_name
1
A
2
B
3
C
4
D
Table 2 - data_question is for data values.
id
q_id
period
data_value

I need to calculate A+B+C and that output will insert into data_question table and new question will create in the info_question table.(formulas will change for new question like A/B*100 or A+C and question id will be new generate)
For (A+B+C) Output should be shows like below tables.
data_question table
id
q_id
period
data_value

as you can see some years are missing - I would like to add the rows with missing years, null for column value and I want to do it per specific ids - any ideas?
You can combine GENERATE_SERIES() with a left join do expand the missing years. For example:
select x.id, x.y, t.value
from (select id, generate_series(min(year), max(year)) as y from t group by id) x
left join t on t.id = x.id and t.year = x.y
Result:
id y value
--- ----- -----
1 2015 200
1 2016 3000
1 2017 null

2 2010 455
2 2011 null
2 2012 null

2 2017 null

need help in sql code
create table amish.cte_test
(id int,
grade int,
year int,
diff int)
insert into amish.cte_test
values (101,5,2022,9)
with recursive temp1( id, grade, year, diff) as
(select id, grade , year , diff from amish.cte_test
union all
select id, grade-1, year-1,diff-1 from temp1
where grade-1 > -2)
select * from temp1
I have table A with product_id,cost,year,quarter,... etc columns.
I have another table B with product_id,base_cost,current_year,p_year,p_quarter,p_order columns.
I want to write an update query to update A from B. My conditions are -
WHERE A.product_id=B.product_id
and A.year=B.current_year
and A.year=B.p_year and A.quarter>B.p_quarter
and A.cost=0;
But the problem is, with these conditions if i have more than one rows in B then i only want to update from the row of B which has the minimum of all quarters.
Example 1-
If A has one row as:
product_id cost year quarter
102 0 2019 1
102 0 2019 2
102 0 2019 3
102 0 2019 4
And B has two rows corresponding to the where clause:
product_id cost current_year p_year quarter
102 3.5 2019 2019 3
102 1.8 2019 2019 1
102 0.5 2019 2019 2
Then updated A should be:
product_id cost year quarter
102 0 2019 1
102 1.8 2019 2
102 1.8 2019 3
102 1.8 2019 4
This is a greatest-n-per-group problem which you need to apply to the table b in a sub-select:
UPDATE A
SET cost = B.base_cost
FROM (
select distinct on (product_id, current_year) product_id, current_year, cost
from b
order by product_id, current_year, quarter
) b
WHERE A.product_id = B.product_id
AND A.year = B.current_year
AND A.cost = 0
I've a table data as below, now I need to fetch the record with in same code, where (Value2-Value1)*2 of one row >= (Value2-Value1) of consequtive date row. (all dates are uniform with in all codes)
---------------------------------------
code Date Value1 Value2
---------------------------------------
1 1-1-2018 13 14
1 2-1-2018 14 16
1 4-1-2018 15 18
2 1-1-2019 1 3
2 2-1-2018 2 3
2 4-1-2018 3 7
ex: output needs to be
1 1-1-2018 13 14
as I am begginer to SQL coding, tried my best, but cannot get through with compare only on consequtive dates.
Use a self join.
You can specify all the conditions you've listed in the ON clause:
SELECT T0.code, T0.Date, T0.Value1, T0.Value2
FROM Table As T0
JOIN Table As T1
ON T0.code = T1.code
AND T0.Date = DateAdd(Day, 1, T1.Date)
AND (T0.Value2 - T0.Value1) * 2 >= T1.Value2 - T1.Value1
id o_num d_num

I have a table like this, there are total 20 o_num in the table, and i want to select all the row that o_num is 1 then group by the d_num to count the id number, and them change the o_num to 2, until o_num to 20. and the result is in one table.
here is my code for 1 time:
SELECT COUNT(id), o_num, d_num
FROM table1
WHERE o_num = 1
GROUP BY o_num, d_num
how can i change the code to get my table
I want get the reselt like this，a table with 3 columns
sum o_num d_num
9 1 1
8 1 2
4 1 3
……
5 1 20
4 2 1
6 2 2
8 2 3
