I have this script:
SELECT 'pro' as descript, COUNT(*) as cnt FROM Trade.TradesMen where TradesManAccountType_Value = 2 AND HasTradeListing = 1
UNION ALL
SELECT 'std' as descript, COUNT(*) as cnt FROM Trade.TradesMen tm
INNER JOIN Membership.Members m ON m.MemberId = tm.MemberId
INNER JOIN aspnet_Membership am ON am.UserId = m.AspNetUserId
WHERE tm.TradesManAccountType_Value = 1 AND tm.HasTradeListing = 1 AND am.IsApproved = 1
UNION ALL
SELECT 'listed' as descript, COUNT(*) as cnt FROM Trade.TradesMen where HasTradeListing = 1
UNION ALL
SELECT 'all' as descript, COUNT(*) as cnt FROM Trade.TradesMen
insert into Admin.VersionHistory values(4,cnt,CURRENT_TIMESTAMP) //is NOT correct
this produces:
1 pro 32549
2 std 13096
3 listed 230547
4 all 231638
I want to add the above as rows in my table: Admin.VersionHistory which has columns VersionHistory type int auto-increment and is the ID, Version which is of type varchar(50) and a datatime stamp
thanks
(updated with new info from OP)
From the top of my head, it would look something like this.
INSERT INTO Admin.VersionHistory (Version, NumberOf, DateAndTime)
SELECT descript, CAST(cnt AS VARCHAR), SYSDATE
FROM
(
SELECT 'pro' as descript, COUNT(*) as cnt FROM Trade.TradesMen where TradesManAccountType_Value = 2 AND HasTradeListing = 1
UNION ALL
SELECT 'std' as descript, COUNT(*) as cnt FROM Trade.TradesMen tm
INNER JOIN Membership.Members m ON m.MemberId = tm.MemberId
INNER JOIN aspnet_Membership am ON am.UserId = m.AspNetUserId
WHERE tm.TradesManAccountType_Value = 1 AND tm.HasTradeListing = 1 AND am.IsApproved = 1
UNION ALL
SELECT 'listed' as descript, COUNT(*) as cnt FROM Trade.TradesMen where HasTradeListing = 1
UNION ALL
SELECT 'all' as descript, COUNT(*) as cnt FROM Trade.TradesMen
) ;
This is assuming the VersionHistoryIdcolumn is automatically seeded by the database. With each insert, an ID number will be automatically inserted.
Not sure what you want to achieve with the CURRENT_TIMESTAMP column though. I put SYSDATE as a timestamp.
The NumberOf column contains the count data. Name it as you see fit.
insert into Admin.VersionHistory
SELECT 'all', COUNT(*),current_timestamp FROM Trade.TradesMen

I am trying to get the max date by account from 3 different tables and view those dates side by side. I created a separate query for each table, merged the results with UNION ALL, and then wrapped all that in a PIVOT.
The first 2 sections in the link/pic below show what I have been able to accomplish and the 3rd section is what I would like to do.
Query results by step
How can I get the results from 2 of the tables to repeat? Is that possible?

Everything is possible. You only need a window function to make the value repeat across rows w/o data.
--Assuming current query is QC
With QC as (

select code, account, grouping,
--cash,
first_value(cash) over (partition by code, account order by grouping asc rows unbounded preceding) as cash_repeat,
perf,
--pos,
first_value(pos) over (partition by code, account order by grouping asc rows unbounded preceding) as pos_repeat
from QC

I have a table that looks like this:
A slowly changing dimension type 2, according to Kimball.
Key is just a surrogate key, a key to make rows unique.
As you can see there are three rows for product A.
Timelines for this product are ok. During time the description of the product changes.
From 1-1-2020 up until 4-1-2020 the description of this product was ProdA1.
From 5-1-2020 up until 12-2-2020 the description of this product was ProdA2 etc.
If you look at product B, you see there are gaps in the timeline.
We use DB2 V12 z/Os. How can I check if there are gaps in the timelines for each and every product?
Tried this, but doesn't work
with selectie (key, tel) as
(select product, count(*)
from PROD_TAB
group by product
having count(*) > 1)
Select * from
PROD_TAB A
inner join selectie B
on A.product = B.product
Where not exists
(SELECT 1 from PROD_TAB C
WHERE A.product = C.product
AND A.END_DATE + 1 DAY = C.START_DATE
)
Does anyone know the answer?
The following query returns all gaps for all products.
The idea is to enumerate (RN column) all periods inside each product by START_DATE and join each record with its next period record.
WITH
/*
MYTAB (PRODUCT, DESCRIPTION, START_DATE, END_DATE) AS
(
SELECT 'A', 'ProdA1', DATE('2020-01-01'), DATE('2020-01-04') FROM SYSIBM.SYSDUMMY1
UNION ALL SELECT 'A', 'ProdA2', DATE('2020-01-05'), DATE('2020-02-12') FROM SYSIBM.SYSDUMMY1
UNION ALL SELECT 'A', 'ProdA3', DATE('2020-02-13'), DATE('2020-12-31') FROM SYSIBM.SYSDUMMY1
UNION ALL SELECT 'B', 'ProdB1', DATE('2020-01-05'), DATE('2020-01-09') FROM SYSIBM.SYSDUMMY1
UNION ALL SELECT 'B', 'ProdB2', DATE('2020-01-12'), DATE('2020-03-14') FROM SYSIBM.SYSDUMMY1
UNION ALL SELECT 'B', 'ProdB3', DATE('2020-03-15'), DATE('2020-04-18') FROM SYSIBM.SYSDUMMY1
UNION ALL SELECT 'B', 'ProdB4', DATE('2020-04-16'), DATE('2020-05-03') FROM SYSIBM.SYSDUMMY1
)

*/
MYTAB_ENUM AS
(
SELECT
T.*
, ROWNUMBER() OVER (PARTITION BY PRODUCT ORDER BY START_DATE) RN
FROM MYTAB T
)
SELECT A.PRODUCT, A.END_DATE + 1 START_DT, B.START_DATE - 1 END_DT
FROM MYTAB_ENUM A
JOIN MYTAB_ENUM B ON B.PRODUCT = A.PRODUCT AND B.RN = A.RN + 1
WHERE A.END_DATE + 1 <> B.START_DATE
AND A.END_DATE < B.START_DATE;
The result is:
|PRODUCT|START_DT |END_DT |
|-------|----------|----------|
|B |2020-01-10|2020-01-11|
May be more efficient way:
WITH MYTAB2 AS

Thnx Mark, will try this one of these days.
Never heard of LAG in DB2 V12 for z/Os
Will read about it

The query above isn't working for me. It still skips days where the COUNT is NULL for it's c.DT.
c.DT and p.PatternDate are both time DateTime, although c.DT can't be NULL. It is actually the PK for the table. It is populated as DateTimes for every single day from 2015 to 2049, so the records for those days exist.
Another weird thing I noticed is that nothing returns at all when I join C.DT = p.PatternDate without a CAST or CONVERT to a Date style. Not sure why when they are both DateTimes.
There are a few things to talk about here. At this stage it's not clear what you're actually trying to count. If it's the number of "patterns" per day for the month of Jan 2019, then:
Your BETWEEN will also count any activity occurring on 1 Feb,
It looks like one pattern could have multiple results, potentially causing a miscount
It looks like one pattern could have multiple details, potentially causing a miscount
If one pattern has say 3 eligible results, and also 4 details, you'll get the cross product of them. Your count will be 12.
I'm going to assume:
you only want the distinct number of patterns, regardless of the number of details and results.
You only want January's activity

I'm trying to select all records from a table "Table1" but I want a new column called "HasException" that contains a "0" or a "1". "HasException" must be "0" if the count of row matching the current Id from "Table2" is equal to 0, else it returns 1.
Here's what I've done so far, but it doesn't works:
SELECT *,
CONVERT(bit, (CASE WHEN (SELECT count(Id) FROM Table2 WHERE Table1.Id=Table2.Id) = 0 THEN 0 ELSE 1 END)) AS HasException
FROM Table1
You want to join the tables (and group on ID) before you can compare the two values like this:
SELECT dbo.Table_1.*,
CASE WHEN COUNT(dbo.Table_2.ID) = 0 THEN
0
ELSE
1
END
AS HasException
FROM dbo.Table_1 LEFT OUTER JOIN
dbo.Table_2 ON dbo.Table_1.ID = dbo.Table_2.ID
GROUP BY dbo.Table_1.ID
perhaps something like, assuming you meant table2?
SELECT *,
CAST(CASE WHEN COUNT(table2.id) = 0 THEN 0 ELSE 1 END AS bit) AS HasException
FROM
Table1
LEFT JOIN
Table2 ON Table1.Id=Table2.Id
GROUP BY
Table1.id
select
T1.*,
case when T2.Id is null then 0 else 1 end as HasException
from Table1 as T1
left outer join
(
select distinct Id
from Table2
) as T2
on T1.Id = T2.Id
Can someone help me with this query?
SELECT p.OwnerName, SUM(ru.MonthlyRent) AS PotentinalRent, SUM(

WHERE t.UnitID = ru.ID)
) AS ExpectedRent
FROM tblRentalUnit ru
LEFT JOIN tblProperty p ON p.ID = ru.PropertyID
GROUP BY p.OwnerName
I'm having problems with the second sum, it won't let me do it. Evidently SUM won't work on subqueries, but I need to calculate the expected rent (MonthlyRent if there is a tenant assigned to the RentalUnit's id, 0 of they're not). How can I make this work?
SELECT p.OwnerName, SUM(ru.MonthlyRent) AS PotentialRent, SUM(cnt) AS ExpectedRent
FROM tblRentalUnit ru
LEFT JOIN
tblProperty p
ON p.ID = ru.PropertyID
OUTER APPLY
(
SELECT COUNT(t.id) * ru.MonthlyRent AS cnt
FROM tblTenant t
WHERE t.UnitID = ru.ID
) td
GROUP BY p.OwnerName
Here's a test script to check:
WITH tblRentalUnit AS
(
SELECT 1 AS id, 100 AS MonthlyRent, 1 AS PropertyID
UNION ALL
SELECT 2 AS id, 300 AS MonthlyRent, 2 AS PropertyID
),
tblProperty AS
(
SELECT 1 AS id, 'Owner 1' AS OwnerName
UNION ALL
SELECT 2 AS id, 'Owner 2' AS OwnerName
),
tblTenant AS
(
SELECT 1 AS id, 1 AS UnitID
UNION ALL
SELECT 2 AS id, 1 AS UnitID
)
SELECT p.OwnerName, SUM(ru.MonthlyRent) AS PotentialRent, SUM(cnt) AS ExpectedRent
FROM tblRentalUnit ru
LEFT JOIN
tblProperty p
ON p.ID = ru.PropertyID
OUTER APPLY
(
SELECT COUNT(t.id) * ru.MonthlyRent AS cnt
FROM tblTenant t
WHERE t.UnitID = ru.ID
) td
GROUP BY p.OwnerName
What is the meaning of the sum of the unitMonthlyRent times the number of tenants, for some partiicular rental unit (COUNT(t.ID) * ru.MonthlyRent )?
Is it the case that all you are trying to do is see the difference between the total potential rent from all untis versus the expected rent (From only occcupied units) ? If so, then try this
Select p.OwnerName,
Sum(r.MonthlyRent) AS PotentinalRent,
Sum(Case t.Id When Null Then 0
Else r.MonthlyRent End) ExpectedRent
From tblRentalUnit r
Left Join tblTenant t
On t.UnitID = r.ID
left Join tblProperty p
On p.ID = r.PropertyID)
Group By p.OwnerName
