How do you select from a date range as the data source - sql

Short of creating a table with all of the values of a date range, how would I select from a datarange as a datasource.
What I'm trying to accomplish is to create a running total of all items created within the same week from separate tables, while showing weeks with 0 new
example table:
items
-----------------------------
created_on | name | type
-----------------------------
2012-01-01 | Cards | 1
2012-01-09 | Red Pen | 2
2012-01-31 | Pencil | 2
2012-02-01 | Blue Pen | 2
types
--------------
name | id
--------------
Fun | 1
Writing | 2
sample output:
----------------------------
year | week | fun | writing
----------------------------
2012 | 1 | 1 | 0
2012 | 2 | 0 | 1
2012 | 3 | 0 | 0
2012 | 4 | 0 | 0
2012 | 5 | 0 | 2

You could generate a number series for the week numbers
SELECT
w.week
FROM
(SELECT generate_series(1,52) as week) as w
Example
SELECT
w.year,
w.week,
COUNT(i1) as fun,
COUNT(i2) as writing
FROM (SELECT 2012 as year, generate_series(1,6) as week) as w
LEFT JOIN items i1 ON i1.type = 1 AND w.week = EXTRACT(WEEK FROM i1.created_on)
LEFT JOIN items i2 ON i2.type = 2 AND w.week = EXTRACT(WEEK FROM i2.created_on)
GROUP BY
w.year,
w.week
ORDER BY
w.year,
w.week

Very close erikxiv, but you got me in the right direction. I have multiple tables I need to grab information from, this the additional select in the select fields.
select
date_year.num,
date_week.num,
( select count(*) from items x
and EXTRACT(YEAR FROM x.created_on) = date_year.num
and EXTRACT(WEEK FROM x.created_on) = date_week.num
) as item_count
from
(SELECT generate_series(2011, date_part('year', CURRENT_DATE)::INTEGER) as num) as date_year,
(SELECT generate_series(1,52) as num) as date_week
where
(
date_year.num < EXTRACT (YEAR FROM CURRENT_DATE)
OR
(
date_year.num = EXTRACT (YEAR FROM CURRENT_DATE) AND
date_week.num <= EXTRACT (WEEK FROM CURRENT_DATE)
)
)

Query for displaying count per type for each date in range

Using PostgreSQL, I have two tables (lunch_order & lunch_list).
The two table is connected by lunch_id
What I want to do is to display a query that contain total count from each type of lunch for each day in a month
lunch_order
lunch_list
This is my current query syntax:
select true_lunch_name as Lunch_Name,
count(*) filter (where order_date = '2021-12-21' ) as day1,
count(*) filter (where order_date = '2021-12-22' ) as day2,
count(*) filter (where order_date = '2021-12-23' ) as day3
.....
from project1.lunch_order ord inner join project1.lunch_list list on ord.lunch_type = list.lunch_id
where order_date between '2021-12-21' and '2021-12-31' and list.is_active = 'true' and list.lunch_id != '1'
group by true_lunch_name,lunch_id order by lunch_id asc
This is the result with only 3 days selected for now:
But I was wondering, is there another ways to do it.
Because If I do it like this, I need to make 4 kind of queries for each type of months (28days, 29days, 30days, and 31days)
This Single SQL will work for all months. This is for the current example. You can adjust the number and dates.
SQL:
SELECT lunch_name,
Sum(day1) "day1",
Sum(day2) "day2",
Sum(day3) "day3",
Sum(day4) "day4",
Sum(day5) "day5",
Sum(day6) "day6",
Sum(day7) "day7",
Sum(day8) "day8"
FROM (SELECT lunch_name,
CASE
WHEN Extract(day FROM order_date) = 21 THEN cnt
END "day1",
CASE
WHEN Extract(day FROM order_date) = 22 THEN cnt
END "day2",
CASE
WHEN Extract(day FROM order_date) = 23 THEN cnt
END "day3",
CASE
WHEN Extract(day FROM order_date) = 24 THEN cnt
END "day4",
CASE
WHEN Extract(day FROM order_date) = 25 THEN cnt
END "day5",
CASE
WHEN Extract(day FROM order_date) = 26 THEN cnt
END "day6",
CASE
WHEN Extract(day FROM order_date) = 27 THEN cnt
END "day7",
CASE
WHEN Extract(day FROM order_date) = 28 THEN cnt
END "day8"
FROM (SELECT DISTINCT lunch_name,
order_date,
Count(lunch_name)
OVER(
partition BY lunch_name, order_date
ORDER BY order_date) cnt
FROM lunch_order lo
INNER JOIN lunch_list ll
ON ll.lunch_id = lo.lunch_type) inline_view)
final_inline_view
GROUP BY lunch_name;
Output:
lunch_name | day1 | day2 | day3 | day4 | day5 | day6 | day7 | day8
------------+------+------+------+------+------+------+------+------
ccc | | | 1 | 1 | | | 1 | 1
bbb | 2 | 1 | | | | | | 1
(2 rows)
Setup:
create table lunch_order(lunch_type int , order_date date);
create table lunch_list(lunch_id int,lunch_name varchar(10));
insert into lunch_order values
,(20,'2021-12-22'),(22,'2021-12-23'),(22,'2021-12-24'),(22,'2021-12-27'),(20,'2021-12-28'),(22,'2021-12-28');
insert into lunch_list values(1,'aaa'),(20,'bbb'),(22,'ccc'),(23,'ddd'),(24,'eee');

SQL Server - Insert lines with null values when month doesn't exist

I have a table like this one:
Yr | Mnth | W_ID | X_ID | Y_ID | Z_ID | Purchases | Sales | Returns |
2015 | 10 | 1 | 5210 | 1402 | 2 | 1000.00 | etc | etc |
2015 | 12 | 1 | 5210 | 1402 | 2 | 12000.00 | etc | etc |
2016 | 1 | 1 | 5210 | 1402 | 2 | 1000.00 | etc | etc |
2016 | 3 | 1 | 5210 | 1402 | 2 | etc | etc | etc |
2014 | 3 | 9 | 880 | 2 | 7 | etc | etc | etc |
2014 | 12 | 9 | 880 | 2 | 7 | etc | etc | etc |
2015 | 5 | 9 | 880 | 2 | 7 | etc | etc | etc |
2015 | 7 | 9 | 880 | 2 | 7 | etc | etc | etc |
For each combination of (W, X, Y, Z) I would like to insert the months that don't appear in the table and are between the first and last month.
In this example, for combination (W=1, X=5210, Y=1402, Z=2), I would like to have additional rows for 2015/11 and 2016/02, where Purchases, Sales and Returns are NULL. For combination (W=9, X=880, Y=2, Z=7) I would like to have additional rows for months between 2014/4 and 2014/11, 2015/01 and 2015/04, 2016/06.
I hope I have explained myself correctly.
Thank you in advance for any help you can provide.
The process is rather cumbersome in this case, but quite possible. One method uses a recursive CTE. Another uses a numbers table. I'm going to use the latter.
The idea is:
Find the minimum and maximum values for the year/month combination for each set of ids. For this, the values will be turned into months since time 0 using the formula year*12 + month.
Generate a bunch of numbers.
Generate all rows between the two values for each combination of ids.
For each generated row, use arithmetic to re-extract the year and month.
Use left join to bring in the original data.
The query looks like:
with n as (
select row_number() over (order by (select null)) - 1 as n -- start at 0
from master.spt_values
),
minmax as (
select w_id, x_id, y_id, z_id, min(yr*12 + mnth) as minyyyymm,
max(yr*12 + mnth) as maxyyyymm
from t
group by w_id, x_id, y_id, z_id
),
wxyz as (
select minmax.*, minmax.minyyyymm + n.n,
(minmax.minyyyymm + n.n) / 12 as yyyy,
((minmax.minyyyymm + n.n) % 12) + 1 as mm
from minmax join
n
on minmax.minyyyymm + n.n <= minmax.maxyyyymm
)
select wxyz.yyyy, wxyz.mm, wxyz.w_id, wxyz.x_id, wxyz.y_id, wxyz.z_id,
<columns from t here>
from wxyz left join
t
on wxyz.w_id = t.w_id and wxyz.x_id = t.x_id and wxyz.y_id = t.y_id and
wxyz.z_id = t.z_id and wxyz.yyyy = t.yr and wxyz.mm = t.mnth;
Thank you for your help.
Your solution works, but I noticed it is not very good in terms of performance, but meanwhile I have managed to get a solution for my problem.
DECLARE #start_date DATE, #end_date DATE;
SET #start_date = (SELECT MIN(EOMONTH(DATEFROMPARTS(Yr , Mnth, 1))) FROM Table_Input);
SET #end_date = (SELECT MAX(EOMONTH(DATEFROMPARTS(Yr , Mnth, 1))) FROM Table_Input);
DECLARE #tdates TABLE (Period DATE, Yr INT, Mnth INT);
WHILE #start_date <= #end_date
BEGIN
INSERT INTO #tdates(PEriod, Yr, Mnth) VALUES(#start_date, YEAR(#start_date), MONTH(#start_date));
SET #start_date = EOMONTH(DATEADD(mm,1,DATEFROMPARTS(YEAR(#start_date), MONTH(#start_date), 1)));

AND TP.Yr = TA.Yr
AND TP.Mnth = TA.Mnth
ORDER BY TP.W_ID, TP.X_ID, TP.Y_ID, TP.Z_ID, TP.Yr, TP.Mnth;
I do the following:
Get the Min and Max date of the entire table - #start_date and #end_date variables;
Create an auxiliary table with all dates between Min and Max - #tdates table;
Get all the combinations of (W_ID, X_ID, Y_ID, Z_ID) along with the min and max dates of that combination - #pks table;
Create the cartesian product between #tdates and #pks, and in the WHERE clause I filter the results between the Min and Max of the combination;
Compute a LEFT JOIN of the cartesian product table with the input data table.

Multiple sql query or Cursor?

I need help on something that seems to be complex to me.
I made a query to create a tbl1 which is the Cartesian product of the tables Item and Warehouse. It give’s me back all items in all warehouses:
SELECT i.ItemID, w.WarehouseID
FROM Item i, Warehouse w
I made a second query (tbl2) where I check the date of the last document previous or equal to a variable date (#datevar) and whose quantity rule is 1 (PhysicalQtyRule = 1), this by Item and Warehouse, obtained from StockHistory table
SELECT MAX(CreateDate) AS [DATE1], ItemID, Quantity, WarehouseID
FROM StockHistory
WHERE PhysicalQtyRule = 1 AND CreateDate <= #datevar
GROUP BY ItemID, Quantity, WarehouseID
Now, I need more three steps:
Build a third table containing per item and warehouse the sum of quantity, but the quantity rule is 2 (PhysicalQtyRule = 2) and date between tbl2.date (if exists) and the date of the variable #datevar, obtained from the table StockHistory. Something like that:
SELECT ItemID, WarehouseID, SUM(Quantity)
FROM StockHistory
WHERE PhysicalQtyRule = 2 AND CreateDate > tbl2.DATE1 --If exists
AND CreateDate <= #datevar
GROUP BY ItemID, WarehouseID
Build a fourth table containing per item and warehouse the sum of quantity, but the quantity rule is 3 (PhysicalQtyRule = 3) and date between tbl2.date (if any) and the date of the variable #datevar, obtained from the table StockHistory. Something like that:
SELECT ItemID, WarehouseID, SUM(Quantity)
FROM StockHistory
WHERE PhysicalQtyRule = 3 AND CreateDate > tbl2.DATE1 --If exists
AND CreateDate <= #datevar
GROUP BY ItemID, WarehouseID
Create a final table based on the first one, with an sum quantity column, something like that:
SELECT i.ItemID, w.WarehouseID, tbl2.Quantity + tbl3.Quantity – tbl4.Quantity AS [Qty]
FROM Item i, Warehouse w
I don't know if need cursors (something new for me) or multiple querys, but it's important the best performance because my StockHistory table have millions of records.
Can anyone help-me please? Thank you!
Some sample data, only for one Item and one warehouse:
+--------+-------------+------------+-----------------+----------+
| ItemID | WarehouseID | CreateDate | PhysicalQtyRule | Quantity | Balance | comments
+--------+-------------+------------+-----------------+----------+
| 1234 | 11 | 2013-03-25 | 2 | 35 | 35 | Rule 2 = In
| 1234 | 11 | 2013-03-28 | 3 | 30 | 5 | Rule 3 = Out
| 1234 | 11 | 2013-04-01 | 1 | 3 | 3 | Rule 1 = Reset
| 1234 | 11 | 2013-07-12 | 2 | 40 | 43 | Rule 2 = In
| 1234 | 11 | 2013-09-05 | 3 | 20 | 23 | Rule 3 = Out
| 1234 | 11 | 2013-12-31 | 1 | 25 | 25 | Rule 1 = Reset
| 1234 | 11 | 2014-01-09 | 3 | 11 | 14 | Rule 3 = Out
| 1234 | 11 | 2014-01-16 | 3 | 6 | 8 | Rule 3 = Out
I want to know the balance on any variable date.
Without your data, I can't test this but I believe this should be your solution.

filter by Sum without Grouping

i have a resultset that i generate from a query that Looks like this:
Select Employee, Month, (select case when Status = '---' then 0 Else 1 end) as PlaningValue
From PlanningTable PT
Where Month >= #From Month and Month <= #ToMonth
The Result of this Looks something like this:
|Employee| Month | PlaningValue |
|George | 2014-01 | 1 |
|George | 2014-02 | 1 |
|George | 2014-03 | 0 |
|Andrew | 2014-01 | 0 |
|Andrew | 2014-02 | 1 |
|Andrew | 2014-03 | 0 |
|Howard | 2014-01 | 1 |
|Howard | 2014-02 | 1 |
|Howard | 2014-03 | 1 |
Now what i want is the following:
Filter out Employee's who, over the three month period, have a total planing Value of 3,
in the example above, Howard would be filtered out.
Is there a way to do this nicely or is it all just impossible to even thin ?
(Remark: Since i am going to use the Query on Reporting Services, i can't use the OVER function)
Thank you all for your help
This looks to be SQL Server syntax, as such I you can use windowed functions:
WITH CTE AS
( SELECT Employee,
Month,
PlanningValue = CASE WHEN Status = '---' THEN 0 ELSE 1 END,
Total = SUM(CASE WHEN Status = '---' THEN 0 ELSE 1 END)
OVER (PARTITION BY Employee)
FROM PlanningTable
WHERE Month >= #FromDate
AND Month <= #ToMonth
)
SELECT Employee, Month, PlanningValue
FROM CTE
WHERE Total != 3;
Simplified Example on SQL Fiddle
Try:
select pt.employee, pt.month, pt.planningvalue
from planningtable pt
join planningtable pt2 on pt.employee = pt2.employee
join planningtable pt3 on pt.employee = pt3.employee
join planningtable pt4 on pt.employee = pt4.employee
where month >= #mofrom and month <= #tomonth
and pt2.month = #tomonth
and pt3.month in (select month from planningtable where month > #mofrom and month < #tomonth)
and pt4.month = #mofrom
and pt2.planningvalue + pt3.planningvalue + pt4.planningvalue <> 3

Putting stuff into date ranges in SQL Server 2005

I have a table with week ranges (week number,start date, end date) and a table with tutorial dates (for writing tutors (tutor ID, tutorial_date, tutorial type(A or B).
I want to create two query that shows the week ranges (week 1, week 2) across the top with the tutor names on the side with count of tutorials (of type "A") in that week's date range in each block for that week.
The result should look like this:
Counts of Tutorials of Type "A"
Tutor|Week One|Week Two|Week Three|Week Four|Total
Joe | 3 | 5 | 7 | 8 | 23
Sam | 2 | 4 | 3 | 8 | 17
Meaning that Joe completed 3 tutorials in week one, five in week two, 7 in week three, and 8 in week 4.
The second query should show totals for tutorial type "A" and type "B"
Tutor|Week One|Week Two|Week Three|Week Four|Total |
Joe | 3/1 | 5/3 | 7/2 | 8/2 | 23/8 |
Sam | 2/3 | 4/4 | 3/2 | 8/3 | 17/12 |
Here, in Week One, Joe has done 3 tutorials of type A and 1 of type B.
Sample table data for tutorials (week one)
Tutor | Tutorial_ID | Tutorial Date |Type|
------------------------------------------
Joe | 1 | 2011-01-01 | A |
Joe | 2 | 2011-01-02 | A |
Joe | 3 | 2011-01-03 | A |
Joe | 4 | 2011-01-03 | B |
Sam | 5 | 2011-01-01 | A |
Sam | 6 | 2011-01-02 | A |
Sam | 7 | 2011-01-03 | B |
The week table looks like this:
weekNumber |startDate |endDate
1 |2011-01-01|2011-01-15
I'd like to gen this in SQL Server 2005
There are a few ways to do this.
For query one, where you only need to PIVOT on type 'A' then you can do just a PIVOT
select *
from
(
select w1.tutor
, w1.type
, wk.weeknumber
from w1
inner join wk
on w1.tutorialdate between wk.startdate and wk.enddate
where w1.type = 'a'
) x
pivot
(
count(type)
for weeknumber in ([1])
)p
See SQL Fiddle with Demo
Or you can use a Count() with a CASE statement.
select w1.tutor
, COUNT(CASE WHEN w1.type = 'A' THEN 1 ELSE null END) [Week One]
from w1
inner join wk
on w1.tutorialdate between wk.startdate and wk.enddate
group by w1.tutor
See SQL Fiddle with Demo
But for the second query, I would just use a Count() with a CASE
select w1.tutor
, Cast(COUNT(CASE WHEN w1.type = 'A' AND wk.weeknumber = 1 THEN 1 ELSE null END) as varchar(10))
+ ' / '
+ Cast(COUNT(CASE WHEN w1.type = 'B' AND wk.weeknumber = 1 THEN 1 ELSE null END) as varchar(10)) [Week One]
, Cast(COUNT(CASE WHEN w1.type = 'A' AND wk.weeknumber = 2 THEN 1 ELSE null END) as varchar(10))
+ ' / '
+ Cast(COUNT(CASE WHEN w1.type = 'B' AND wk.weeknumber = 2 THEN 1 ELSE null END) as varchar(10)) [Week Two]
from w1
inner join wk
on w1.tutorialdate between wk.startdate and wk.enddate
group by w1.tutor
See SQL Fiddle with Demo
Edit as AndriyM pointed out the second could be done with a PIVOT here is a solution for the Second query:
SELECT *
FROM
(
select distinct w1.tutor
, wk.weeknumber
, left(total, len(total)-1) Totals
FROM w1
inner join wk
on w1.tutorialdate between wk.startdate and wk.enddate
CROSS APPLY
(
SELECT cast(count(w2.type) as varchar(max)) + ' / '
from w1 w2
inner join wk wk2
on w2.tutorialdate between wk2.startdate and wk2.enddate
WHERE w2.tutor = w1.tutor
AND wk2.weeknumber = wk.weeknumber
group by w2.tutor, wk2.weeknumber, w2.type
FOR XML PATH('')
) D ( total )
) x
PIVOT
(
min(totals)
for weeknumber in ([1], [2])
) p
