Full Outer Join Subqueries works until last part then ORA-013113 - sql

I've been task to implement a query that will identify and provide datetime marks using a specific date and time range for each user. Basically first scan last scan throughout the entire shift at specific intervals.
I set a UI that prompts user for date time that will be used within the query and then smaller subqueries to parse out the data I need. Individually every works as I expect but when I get to the last set it breaks and I encounter the following error:
ORA-03113: end-of-file on communication channel
I can't seem to work around this or think of an alternative way to structure the query to what I need.
I need help w/ either a better method of achieving the same results or a fix to what I already have in place.
This is for an Oracle database 12c
With
UI As

Group Timestamps into intervals of 5 minutes, take value that's closest to timestamp and always give out a value

I'm new to SQL coding and would heavily appreciate help for a problem I'm facing. I have the following SQL script, that gives me the following output (see picture 1):
WITH speicher as(
select a.node as NODE_ID, d.name_0 as NODE_NAME, d.parent as PARENT_ID, c.time_stamp as ZEITSTEMPEL, c.value_num as WERT, b.DESCRIPTION_0 as Beschreibung, TO_CHAR(c.time_stamp, 'HH24:MI:SS') as Uhrzeit
from p_value_relations a, l_nodes d, p_values b, p_value_archive c
where a.node in (select sub_node from l_node_relations r where r.node in (
50028,
49989,
49848
))
and a.node = d.id
and (b."DESCRIPTION_0" like 'Name1' OR b."DESCRIPTION_0" like 'Name2')
and c.time_stamp between SYSDATE-30 AND SYSDATE-1
and a.value = b.id and b.id = c.value)
SELECT WERT as Value, NODE_NAME, ZEITSTEMPEL as Timestamp, Uhrzeit as Time, Beschreibung as Category
FROM speicher
I would like to create time intervals of 5 minutes to output the value. It should always choose the value closest above one on the defined time interval time stamps. If there is no value inside a set 5 minute intervall it should still give out the last value it finds, since the value has not changed in that case. To see what I mean please see the following picture. Any help wold be greatly appreciated. This data is from an oracle database.

Result I would like

Since I do not understand your data, and can't test with it, I present something I could test with. My data has a table which tracks when folks login to a system.
This is not intended as a complete answer, but as something to potentially point you in the right direction;
with time_range
as
(
select rownum, sysdate - (1/288)*rownum time_stamp
from dual
connect By Rownum <= 288*30
)
select time_stamp, min(LOGIN_TIME)
from time_range
left outer join WEB_SECURITY_LOGGED_IN on LOGIN_TIME >= time_stamp
group by time_stamp
order by 1;
Good luck...
Edit:
The with part of the query builds a time_stamp column which has one row for every 5 minutes for the last 30 days. The query portion joins to my login log table which I get the login which is the smallest date/time greater than the time_stamp.

tdate issue I'm facing in SQL query

While fetching count from table by using following query
Select count(*)
from tab
where tdate = '17-05-19' ---> output 0
or
Select count(*)
from tab
where trunc(tdate) = '17-05-19' ---->output 0
If I use:
Select count(*)
from tab
where tdate >sysdate - 1 ---> it returns some count(yesterday+some of the today txn)
But here I want only yesterday txn whenever I fire this query.

But here I want only yesterday txn whenever I fire this query.
You may use this.
Select count (*) from tab where
tdate >= TRUNC(SYSDATE) - 1
AND tdate < TRUNC(SYSDATE)
The advantage of this over using TRUNC on the date column is that it will utilize an index if it exists over tdate

If you tried by using
Select count(*) from tab where trunc(tdate) = date'2019-05-17'
(or, you could use
Select count(*) from tab where to_char(tdate,'dd-mm-yy') = '17-05-19' by formatting through to_char function
or, you could use
Select count(*) from tab where trunc(tdate) = trunc(sysdate)-1 to get only the data for the day before
)
you'd get some results provided you have data for the date 17th May.
So, you need to provide a formatting for your literal as date'2019-05-17'(known as date literal) especially for Oracle DB, it might be used as '2019-05-17' without date part in MySQL as an example.
Btw, trunc function is used to extract the date portion, and remove the time part of a date type column value.
If your table is populated with huge data, therefore performance may matter, then you can even create functional index on trunc(tdate).

Query to find out entries where dates don't overlap

Can anyone help me create a query which will populate a list of DJs who are not already booked in.
My user will select a start date (and time), and an end date (and time) - and then click a button to select a DJ.
I only want those DJs which are available between those time slots to appear in the list.
Here are the two tables which are involved
all I need in the listbox is the DJ Number, and the DJ Name
So far I have this... but it isn't working:
SELECT tblDJ.DJ_No AS [DJ ID], tblDJ.DJ_Name AS Name FROM tblDJ
WHERE (((tblDJ.[DJ_No]) Not In
(SELECT tblBooking.[FK_DJ_No]
FROM tblBooking
WHERE ( (tblBooking.End_Date) >= 01-04-2020 19:30:00 )))) ....etc....
I'm just entering a date in here for now, but obviously it will be stored in a variable once implemented.
Thanks

Implementing OVERLAPS of two intervals would look like:
1st_start_date <= 2nd_end_date and 1st_end_date >= 2nd_start_date
where 1st and 2nd values are markers of different events.
You could use that logic in combination with NOT EXISTS to discard those djs that are unavailable at a given time:
select dj_no, dj_name
from tbldj d
where not exists (
select 1
from tblbooking b
where b.fk_dj_no = d.dj_no
and b.start_date <= #END DATE#
and b.end_date >= #START DATE#
)
You just need to replace #START DATE# and #END DATE# with your values.
This does work because there are following assumptions:
Start date of the first event is prior to end date of that event
Start date of the second event is prior to end date of that event
Which seems logical, right?

The date in the SQL needs to be wrapped between two # in order for MS-Access to recognize it as a date:
select *
from tblDJ
where DJ_No not in
(
select FK_DJ_No
from tblBooking
where End_Date >= #2020-04-01 19:30:00#
)
Other than that you query will work.

counting date and time for historical reporting

I am currently working on a query that will be used in junction with share-point to run reports. I have a query that I know will work with Oracle, but the company I am working for is running SQL Server 2005.
What the report will do is give the person the ability to select any date and time, and give the count for that specific operation. The problem is that there are large gaps in the time stamps (because it takes a little while for the product to get to the next operation). The date type is varchar, so i used substrings to parse out the year, month, day, and time. I have sample data available.
The people looking at the reports want the ability to say at this time and day how many units went through this operation.
I know this is is confusing, let me know if you need any clarification.
Here is the oracle syntax
SELECT T3.PAYMENT_DATE, T3."Hr", T3."Min",
(SELECT COUNT(*)
FROM INVOICE_ARCHIVE T4
WHERE TO_NUMBER(TO_CHAR(T4.PAYMENT_DATE, 'MM')) <= T3."Hr"
AND TO_NUMBER(TO_CHAR(T4.PAYMENT_DATE, 'DD')) <= T3."Min") AS "NUM"
FROM(SELECT T1.PAYMENT_DATE, T2."Hr", T2."Min"
FROM (SELECT (FLOOR((LEVEL + 359)/60)) AS "Hr",
MOD((LEVEL + 359), 60) AS "Min"
FROM dual CONNECT BY LEVEL <= 961) T2, INVOICE_ARCHIVE T1
ORDER BY T1.PAYMENT_DATE, T2."Hr", T2."Min") T3

The answer to your question is the datepart() function in SQL Server. This will allow you to extract minutes and hours from dates.
The harder part is the "connect by level" portion. How is this being used? You might need to use recursive CTEs to handle this.
With the little hint from spencer, the following may suffice for your query:
SELECT T3.PAYMENT_DATE, T3."Hr", T3."Min",
(SELECT COUNT(*)
FROM INVOICE_ARCHIVE T4
WHERE datepart(month, T4.PAYMENT_DATE) <= T3."Hr" AND
datepart(day, T4.PAYMENT_DATE, 'DD') <= T3."Min"
) AS "NUM"
FROM (SELECT T1.PAYMENT_DATE, T2."Hr", T2."Min"
FROM (SELECT top 961 (FLOOR((LEVEL + 359)/60)) AS "Hr",
MOD((LEVEL + 359), 60) AS "Min"
FROM (select top 961 row_number() over (order by (select NULL)) as level
from invoice_archive
) t
) T2 cross join
INVOICE_ARCHIVE T1
) T3
ORDER BY T3.PAYMENT_DATE, T3."Hr", T3."Min"
I made the following changes:
Changed the date arithmetic to use datepart() instead of to_char() .
Replaced the method for getting a list of numbers, by using row_number() instead of connect by level
Made the cross join explicit
Moved the order by to the outer query, since neither SQL Server nor Oracle guarantee the results of an order by in a subquery (and SQL Server does not allow it unless you have a "TOP" query)

Calculating working days including holidays between dates without a calendar table in oracle SQL

Okay, so I've done quite a lot of reading on the possibility of emulating the networkdays function of excel in sql, and have come to the conclusion that by far the easiest solution is to have a calendar table which will flag working days or non working days. However, due to circumstances out of my control, we don't have access to such a luxury and it's unlikely that we will any time in the near future.
Currently I have managed to bodge together what is undoubtedly a horrible ineffecient query in SQL that does work - the catch is, it will only work for a single client record at a time.

Basically, I'm wondering if a) I should stop wasting my time on this or b) is it possible to get this to work for multiple clients? Any pointers appreciated thanks!
Edit: Further clarification - I already work out timescales using excel, but it would be ideal if we could do it in the report as the report in question is something that we would like end users to be able to run without any further manipulation.
Edit:
MarkBannister's answer works perfectly albeit slowly (though I had expected as much given it's not the preferred solution) - the challenge now lies in me integrating this into an existing report!

This will produce a virtual table populated with dates from 01 January 2000 to 10 years after the current date, with all weekends marked as non-working days and all days specified in the second in clause (ie. up to 27 December 2011) also marked as non-working days.
The drawback of this method (or any method where the holiday dates are hardcoded into the query) is that each time new holiday dates are defined, every single query that uses this approach will have to have those dates added.

If you can't use a calendar table in Oracle, you might be better off exporting to Excel. Brute force always works.
Networkdays() "returns the number of whole working days between start_date and end_date. Working days exclude weekends and any dates identified in holidays."
Excluding weekends seems fairly straightforward. Every 7-day period will contain two weekend days. You'll just need to take some care with the leftover days.
Holidays are a different story. You have to either store them or pass them as an argument. If you could store them, you'd store them in a calendar table, and your problem would be over. But you can't do that.
So you're looking at passing them as an argument. Off the top of my head--and I haven't had any tea yet this morning--I'd consider a common table expression or a wrapper for a stored procedure.
