Hi Rogan,
After following your advice to have same filters for both queries, I now are 
able to get the results I desire.
I also removed the join for biblioitems and indeed it was not necessary.
No words can express my sincere appreciation for the time you took to help me 
out. I can only say a big big thank you.
Thank you to everyone who tried in their own ways in finding me a solution.

Hi James,
A few thoughts from skimming it.
1) I don't see where you're using biblioitems anywhere in the report unless I'm 
just not seeing it so you probably don't need it for a join.  I don't think 
it'll hurt anything other than slow the report less than  you'll even notice 
but still ... if not needed I'd cut it out.
2) you're going to want the same filters in the second query as the first to 
make sure you get the same numbers
3) you are using a SUM on the statistics type but you can only sum numbers you 
probably want a COUNT there, which you do in the first query but not the second

Hi Rogan,
I reintroduced two filters date abd itemtype. So that i can sekect any date be 
it weekly monthly or quarterly etc. I also have different itemtypes sone of 
which do not start wih a digit and I need to filter them out yo get accurate 
results. (Your advice on whether the filters might be sn issue is verywelcome)
Below is my query.

SELECT CONCAT(SUBSTRING(itemcallnumber,1,1), '00') AS "CLASS", 
count(statistics.type) AS 'NUMBER'
FROM borrowers
  LEFT JOIN statistics ON (statistics.borrowernumber=borrowers.borrowernumber)
  LEFT JOIN items ON (items.itemnumber = statistics.itemnumber)
  LEFT JOIN biblioitems ON (biblioitems.biblioitemnumber = 
items.biblioitemnumber)
WHERE statistics.type IN ('issue', 'renew')
AND date(datetime) BETWEEN <<Date BETWEEN (yyyy-mm-dd)|date>> AND <<and 
(yyyy-mm-dd)|date>>
AND items.itype = <<Item type|itemtypes>>
GROUP BY SUBSTRING(itemcallnumber,1,1)
UNION ALL
SELECT "TOTAL" AS "CLASS", SUM(statistics.type) AS 'NUMBER'
FROM borrowers
  LEFT JOIN statistics ON (statistics.borrowernumber=borrowers.borrowernumber)
  LEFT JOIN items ON (items.itemnumber = statistics.itemnumber)
  LEFT JOIN biblioitems ON (biblioitems.biblioitemnumber = 
items.biblioitemnumber)
WHERE statistics.type IN ('issue', 'renew')

Hi James,
The query I posted worked with my quick test.  Could you post your query as it 
is now?

Hi Rogan and All,

I cant thank you enough for the tremendous effort you have put towards helping 
me solve my problem.
You do indeed understand well what I need.
The UNION ALL is working well by adding a new row below the last class group. 
However the SUM function is returning a 0 (zero). It seems its not adding up 
the numbers.
Please dont give up but help me find out the last remaining bit. We are almost 
there.
Most appreciated
James

Hi James,
If I'm understanding correctly you want an additional row giving a sum of all 
the numbers in addition to the per class one?  The simplest way  it occurs to 
me to do that is with a UNION ALL statement.  I've taken some filters out for 
brevity but this illustrates the approach:
SELECT CONCAT(SUBSTRING(itemcallnumber,1,1), '00') AS "CLASS", 
count(statistics.type) AS 'NUMBER'
FROM borrowers
  LEFT JOIN statistics ON (statistics.borrowernumber=borrowers.borrowernumber)
  LEFT JOIN items ON (items.itemnumber = statistics.itemnumber)
  LEFT JOIN biblioitems ON (biblioitems.biblioitemnumber = 
items.biblioitemnumber)
WHERE statistics.type IN ('issue', 'renew')
GROUP BY SUBSTRING(itemcallnumber,1,1)
UNION ALL
SELECT "All Classes" AS "CLASS", SUM(statistics.type) AS 'NUMBER'
FROM borrowers
  LEFT JOIN statistics ON (statistics.borrowernumber=borrowers.borrowernumber)
  LEFT JOIN items ON (items.itemnumber = statistics.itemnumber)
  LEFT JOIN biblioitems ON (biblioitems.biblioitemnumber = 
items.biblioitemnumber)
WHERE statistics.type IN ('issue', 'renew')

Basically with UNION ALL you can create other queries that don't have to be 
tied to the data of the previous queries so long as the columns line up.

Hi Rogan and Team,
I really appreciate your assistance towards my problem. The query does indeed 
work to answer my need. Another query was also pushed to me towards the same. 
I'm now looking for a way to SUM my answer to get the total number of books 
issued. Any suggestions would be most welcome for any of the 2 queries. The 
other SQL query is as below: -
SELECT CONCAT(SUBSTRING(itemcallnumber,1,1), '00') AS "CLASS", 
count(statistics.type) AS 'NUMBER'
FROM borrowers
  LEFT JOIN statistics ON (statistics.borrowernumber=borrowers.borrowernumber)
  LEFT JOIN items ON (items.itemnumber = statistics.itemnumber)
  LEFT JOIN biblioitems ON (biblioitems.biblioitemnumber = 
items.biblioitemnumber)
WHERE statistics.type IN ('issue', 'renew')
  AND date(statistics.datetime) BETWEEN <<Date BETWEEN (yyyy-mm-dd)|date>> AND 
<<and (yyyy-mm-dd)|date>>
  AND statistics.itemtype = 'BK'
GROUP BY SUBSTRING(itemcallnumber,1,1)
ORDER BY items.itemcallnumber ASC

N.B My desire is to SUM the NUMBER column as TOTAL.
Please assist team
Warm Regards. JAMES

Hi James,
One simple way to handle it is with a case statement.  The following example 
has a static between filter for the dates but it illustrates this approach. You 
can also do some cleaning to make sure there aren't spaces in front and it 
assumes that all of your DDC numbers in fact start with a digit.  
SELECT
COUNT(*),
CASE 
    WHEN LEFT(it.itemcallnumber,1) = '0' THEN '000s'
    WHEN LEFT(it.itemcallnumber,1) = '1' THEN '100s'
    WHEN LEFT(it.itemcallnumber,1) = '2' THEN '200s'
    WHEN LEFT(it.itemcallnumber,1) = '3' THEN '300s'
    WHEN LEFT(it.itemcallnumber,1) = '4' THEN '400s'
    WHEN LEFT(it.itemcallnumber,1) = '5' THEN '500s'
    WHEN LEFT(it.itemcallnumber,1) = '6' THEN '600s'
    WHEN LEFT(it.itemcallnumber,1) = '7' THEN '700s'
    WHEN LEFT(it.itemcallnumber,1) = '8' THEN '800s'
    WHEN LEFT(it.itemcallnumber,1) = '9' THEN '900s'
    ELSE 'OTHER'
    END
from (SELECT * FROM issues UNION ALL SELECT * FROM old_issues) i 
JOIN items it ON it.itemnumber = i.itemnumber
WHERE DATE(i.timestamp) BETWEEN '2020-02-01' AND '2020-02-29'
GROUP BY 2 ORDER BY 2;

Dear All,



My library uses DDC scheme of classification and we are looking for a

report that will count items checked out allowing us to select day(s) of

issue, select itemtype and group the statistics by DDC 10 broad classes.



*EXAMPLE*



IN a date range say 1st-31st March 2020.



*DDC Class  | NO. of books issued*

000           -               12

100           -               26

200           -               157

.

.

.

900          -               230



The report can generate statistics for a day, month, quarter, e.t.c.



Any assistance however close will be greatly appreciated.



Thank you as you prepare to help



James
