Can MySQL detect the columns created using AS?
Example;
SUM( Mark1 + Mark2) AS '2022_SUM'
SUM( Mark3 + Mark4) AS '2021_SUM'
(2022_SUM + 2021_SUM) AS 'SUM1'
It hits unknown column in field list.
Just write:
SELECT
SUM(Mark1 + Mark2) as '2022_SUM',
SUM(Mark3 + Mark4) as '2021_SUM',
SUM(Mark1 + Mark2) + SUM(Mark3 + Mark4) as 'SUM1'
FROM someTableName
OR
SELECT
2022_SUM,
2021_SUM,
2022_SUM + 2021_SUM as 'SUM1'
FROM (
SELECT
SUM(Mark1 + Mark2) as '2022_SUM',

where the total(sum of all columns) of the colums are miscalculated, i think some of it are not in the computation, i've been wondering why and what is causing this. Please help.
try this:
(spa1+spa2+spa3+spa4)
else try this also:
sum(spa1+spa2)
instead of this:
(sum(sp1) + sum(sp2) + sum(sp3) + sum(sp4) + sum(fsg) + sum(fgg) + sum(ffg) + sum(fsg) + sum(fgf)
+ sum(fff) + sum(g1) + sum(g2) + sum(g3) + sum(gb35) + sum(gb452mm) + sum(gb453mm) + sum(gb454mm)) total

and this code doesn't give me sort order. if I remove the "'ORDER BY (rel6 * 1000)+ (rel7 * 1000) + (rel8 * 90) + (rel9 * 80) + (rel10 * 70) + (rel11 * 60) DESC '" it also give the same result as previous. what's wrong with my SQL code?
Once I set an a column name like this SUM(someColumn) AS [ColumnName], how can I use it afterwards ?
Let's say I build a query like this :
SELECT SUM(foo.A + foo.B + foo.C + foo.D + foo.E) AS [TotalFoo],
SUM(bar.A + bar.B + bar.C + bar.D + bar.E) AS [TotalBar],
-- I need [TotalFooBar]
And in the same select I want the total of [TotalFoo] and [TotalBar]. Is it possible to refere to these columns ? I could do it the long way :
SELECT SUM(foo.A + foo.B + foo.C + foo.D + foo.E) AS [TotalFoo],
SUM(bar.A + bar.B + bar.C + bar.D + bar.E) AS [TotalBar],
SUM((foo.A + foo.B + foo.C + foo.D + foo.E) +
(bar.A + bar.B + bar.C + bar.D + bar.E)) AS [TotalFooBar]
It's ok in this exemple but I have way more columns and it's hard to follow. And then what if I have to use this column ([TotalFooBar])? I'll have to rewrite the whole SUM everytime ?
What I'm looking for is something like this :
SELECT SUM(foo.A + foo.B + foo.C + foo.D + foo.E) AS [TotalFoo],
SUM(bar.A + bar.B + bar.C + bar.D + bar.E) AS [TotalBar],
SUM([TotalFoo] + [TotalBar]) AS [TotalFooBar]
Is it even possible ?
No, you can't do this in the same SELECT statement, but you can use subquery:
SELECT
TotalFoo,
TotalBar,
TotalFoo + TotalBar AS TotalFooBar
FROM
(
SELECT SUM(foo.A + foo.B + foo.C + foo.D + foo.E) AS [TotalFoo],
SUM(bar.A + bar.B + bar.C + bar.D + bar.E) AS [TotalBar],
...
FROM ...
) AS sub
...
or a CTE:
WITH CTE
AS
(
SELECT SUM(foo.A + foo.B + foo.C + foo.D + foo.E) AS [TotalFoo],
SUM(bar.A + bar.B + bar.C + bar.D + bar.E) AS [TotalBar],
...
FROM ...
)
SELECT
TotalFoo,
TotalBar,
TotalFoo + TotalBar AS TotalFooBar
FROM CTE

I just can't manage to make this work under MySQL !
Thanks in advance !
All of the columns used in the joins, where clause and the order by should probably be indexed. You cannot expect any kind of decent performance in any database without indexes. There is nothing very complex about your query, so this is the most likely problem.
Do not return any columns you don't need. For instance why are you returning T_Supr.Suppression when the value will always be nulll based on your where clause?
In mysql you should look at the Explain Plan to see where the problem is with a slow query. In SQL Server look at the Execution PLan. You need to learn how to read these to effectively program in SQL.
