H2, how to update with nested selects? - sql

I have two tables, EVENT and EVENT_REV
EVENT:
╔══════════╦════════════════════╗
║ EVENT_ID ║ SENT_INTO_WF_BY_ID ║
╠══════════╬════════════════════╣
║ 1 ║ null ║
║ 2 ║ null ║
║ 3 ║ null ║
║ 4 ║ null ║
║ 5 ║ null ║
╚══════════╩════════════════════╝
and EVENT_REV:
╔══════════════╦══════════╦═════════╦════════╦════════════╦══════════╗
║ EVENT_REV_ID ║ EVENT_ID ║ USER_ID ║ STATUS ║ VALID_FROM ║ VALID_TO ║
╠══════════════╬══════════╬═════════╬════════╬════════════╬══════════╣
║ 1 ║ 1 ║ 54 ║ 0 ║ 1000 ║ 1001 ║
║ 2 ║ 1 ║ 55 ║ 100 ║ 2000 ║ 2001 ║
║ 3 ║ 1 ║ 56 ║ 200 ║ 3000 ║ 3001 ║
║ 4 ║ 2 ║ 57 ║ 0 ║ 4000 ║ 4001 ║
║ 5 ║ 3 ║ 58 ║ 0 ║ 5000 ║ 5001 ║
║ 6 ║ 3 ║ 59 ║ 100 ║ 6000 ║ null ║
║ 7 ║ 4 ║ 60 ║ 0 ║ 7000 ║ null ║
║ 8 ║ 5 ║ 61 ║ 500 ║ 8000 ║ 8001 ║
║ 9 ║ 5 ║ 62 ║ 600 ║ 9000 ║ 9001 ║
╚══════════════╩══════════╩═════════╩════════╩════════════╩══════════╝
I want to update the EVENT table and set the SENT_INTO_WF_BY_ID
The rule for this is:
event_ids should match (EVENT.EVENT_ID = EVENT_REV.EVENT_ID)
take the row where STATUS is not equal to the STATUS with the lowest VALID_FROM. Which should be the row with the second lowest VALID_FROM
From that row, take the USER_ID
For example:
For the EVENT_ID = 1 it should select the 2nd row from EVENT_REV and put the USER_ID 55 into the SENT_INTO_WF_BY_ID
Because inner joins are not allowed for H2, my query looks like this:
UPDATE event ltm
SET ltm.sent_into_wf_by_id =
(SELECT top 1 ltmRev.user_id
FROM event_rev ltmRev
WHERE ltmRev.event_id = ltm.event_id
AND ltmRev.status !=
(SELECT top 1 EVENT_REV.status
FROM EVENT_REV
ORDER BY valid_from ASC nulls LAST)
ORDER BY ltmRev.valid_to ASC nulls LAST)
The result should look like:
╔══════════╦════════════════════╗
║ EVENT_ID ║ SENT_INTO_WF_BY_ID ║
╠══════════╬════════════════════╣
║ 1 ║ 55 ║
║ 2 ║ null ║
║ 3 ║ 59 ║
║ 4 ║ null ║
║ 5 ║ 62 ║
╚══════════╩════════════════════╝
but it's actually:
╔══════════╦════════════════════╗
║ EVENT_ID ║ SENT_INTO_WF_BY_ID ║
╠══════════╬════════════════════╣
║ 1 ║ 55 ║
║ 2 ║ null ║
║ 3 ║ 59 ║
║ 4 ║ null ║
║ 5 ║ 61 <-- wrong ║
╚══════════╩════════════════════╝

Could solve it with the following query:
UPDATE ltm_op_risk_event ltm
SET ltm.sent_into_wf_by_id =
(SELECT ltmRev.adm_user_id
FROM ltm_op_risk_event_rev ltmRev
WHERE ltmRev.ltm_op_risk_event_id = ltm.ltm_op_risk_event_id
AND ltmRev.status !=
(SELECT ltmRev2.status
FROM LTM_OP_RISK_EVENT_REV ltmRev2
WHERE valid_from IS NOT NULL
AND ltmRev.ltm_op_risk_event_id = ltmRev2.ltm_op_risk_event_id
ORDER BY valid_from ASC LIMIT 1)
ORDER BY ltmRev.valid_to ASC LIMIT 1)
WHERE ltm.sent_into_wf_by_id IS NULL;
The missing part was the AND ltmRev.ltm_op_risk_event_id = ltmRev2.ltm_op_risk_event_id in the innermost select. I first tested this connection with the wrong connections...

How to filter SQL dataset based off value in one column?

I have a table with this structure:
╔══════╦════╦═════════╗
║ Comp ║ ID ║ Desc ║
╠══════╬════╬═════════╣
║ 1 ║ 1 ║ Comp1-1 ║
║ 1 ║ 2 ║ Comp1-2 ║
║ 3 ║ 2 ║ Comp3-2 ║
║ 1 ║ 3 ║ Comp1-3 ║
║ 1 ║ 4 ║ Comp1-4 ║
║ 3 ║ 5 ║ Comp3-5 ║
╚══════╩════╩═════════╝
The dataset I'm creating should have a unique ID.
If an ID exists in Comp1, use that Desc.
If it does not exist in Comp1, use Comp3.
End result should look like this instead:
╔══════╦════╦═════════╗
║ Comp ║ ID ║ Desc ║
╠══════╬════╬═════════╣
║ 1 ║ 1 ║ Comp1-1 ║
║ 1 ║ 2 ║ Comp1-2 ║
║ 1 ║ 3 ║ Comp1-3 ║
║ 1 ║ 4 ║ Comp1-4 ║
║ 3 ║ 5 ║ Comp3-5 ║
╚══════╩════╩═════════╝
I've tried using NOT EXISTS and joining with a subquery but I'm not sure what to Join on.
Using not exists, it looks like:
select t.*
from t
where t.descr like 'Comp1-%' or
not exists (select 1
from t t2
where t2.id = t.id and t2.descr like 'Comp1-%'
);

Sorting and Number results based in order, using multiple columns "order by" criteria

I've been trying to do, with data following the structure:
╔══════════════╦═══════════╦══╗
║ Alphabetical ║ Numerical ║ ║
╠══════════════╬═══════════╬══╣
║ A ║ 15 ║ ║
║ A ║ 30 ║ ║
║ E ║ 100 ║ ║
║ C ║ 45 ║ ║
║ F ║ 25 ║ ║
║ C ║ 65 ║ ║
║ B ║ 25 ║ ║
║ F ║ 35 ║ ║
║ C ║ 100 ║ ║
║ A ║ 10 ║ ║
║ C ║ 20 ║ ║
║ B ║ 5 ║ ║
║ E ║ 10 ║ ║
║ F ║ 85 ║ ║
║ D ║ 30 ║ ║
║ F ║ 1 ║ ║
╚══════════════╩═══════════╩══╝
To get the following:
╔══════════════╦══════╦═════════╗
║ Alphabetical ║ Rank ║ Numeric ║
╠══════════════╬══════╬═════════╣
║ A ║ 1 ║ 30 ║
║ A ║ 2 ║ 15 ║

║ E ║ 1 ║ 100 ║
║ E ║ 2 ║ 10 ║
║ F ║ 1 ║ 85 ║
║ F ║ 2 ║ 35 ║
║ F ║ 3 ║ 25 ║
║ F ║ 4 ║ 1 ║
╚══════════════╩══════╩═════════╝
Basically, to order the alphabetical field in ascending order, the numerical field in descending order and get the order or rank by using the order used for the numerical field, grouped by the alphabetical field.
I have only achieved it if I limit it to one specific value in the Alphabetical column, by using something like:
select ordered_src.*, ROWNUM Rank from (select src.* from Source src where alphabetical = 'A' order by Numeric desc) ordered_src;
But I have no idea how to get the result shown above. Any idea? Also, is there any alternative that will work also in mysql/mssql/etc?
Thanks!
Use row_number():
select s.*,
row_number() over (partition by alphabetical order by numerical desc) as rank
from source s
order by alphabetical, rank;

but i have like 10000 vehicles and big trips and component_values and this query give me the result in like 3 to 6 seconds, is their a batter way to do this with better performance and time?
can i use GENERATED columns in my case and how ?
please any help and many many thanks in advance.

The results returned by this are not what I'm looking for as its not filtering out the days of the week where an employee doesn't do a report. Here is what is being returned:
╔════════════╦══════════╦══════════╦═══╦════╦═══╦════╦═══╦════╦════╗

What do I need to do to get the results I'm looking for?
Add a where clause where report <> 0? Also, you have the report id = report id in the where statement - I'm not sure that's necessary as that's your join clause. Still new to sql, so I'm not sure.
Problem solved.
I inserted the original query into a temp table, then run the following and get the needed data returned.
SELECT #Temp.EmployeeID, #Temp.ReportID, #Temp.Time,
CASE WHEN EmployeeSchedule.M = 0 THEN 0 ELSE 1 END AS M,
CASE WHEN EmployeeSchedule.Tu = 0 THEN 0 ELSE 1 END AS Tu,
CASE WHEN EmployeeSchedule.W = 0 THEN 0 ELSE 1 END AS W,
CASE WHEN EmployeeSchedule.Th = 0 THEN 0 ELSE 1 END AS Th,
CASE WHEN EmployeeSchedule.F = 0 THEN 0 ELSE 1 END AS F,
CASE WHEN EmployeeSchedule.Sa = 0 THEN 0 ELSE 1 END AS Sa,
CASE WHEN EmployeeSchedule.Su = 0 THEN 0 ELSE 1 END AS Su
FROM #Temp
INNER JOIN EmployeeSchedule on #Temp.ReportID = EmployeeSchedule.ReportID
