my table Muster contain following data
And final output I want is
How to query database to get required output
Having 4 identical names is confusing, Not 100 % sure what you mean, but if you want to update the current table with opposite values, this is how to do it. Status will remain the same if it has different values.
UPDATE Muster
SET status = CASE status WHEN 'present' THEN 'absent'
WHEN 'absent' THEN 'present'
ELSE status END
Select * From Muster order by Status
hope this will help you.

I have this code:
SELECT
ZONE_NAME,
ORG_ID,
ORG_SHORT_NAME,
XMSSN_USE
FROM TABLEZ
;
UPDATE TABLEZ
SET TABLEZ.BILL_CYCLE = '1-DEC-2020 4' WHERE (SELECT TABLEZ.XMSSN_USE WHERE TABLEZ.XMSSN_USE=224)
But it doesn't seem to execute. What could be the problem?
You have 2 different query sentences. You should use ; after first query and then write the update query.
Also you need to use some field on the where clause, your where is empty.

I have 2 columns called price and PID in database called seatinginfo.
Both columns will have multiple of the same values like
pid 1,1,1,1,2,2,2,2,2,2,2,3,3,3,3,3
price 10,10,30,40,60,80,70,90,90,90,90 etc
I'm looking to make a query that will give me a list of all unique prices and pick just 1 or the max connected pid.
So example I only want one price,pid like 10,1 30,1 40,1 60,2 etc
Thanks
This is probably as simple as basic aggregation. Something like this should work based on the pretty vague details.
select price
, max(pid)
from YourTable
group by price

i got this table, and i want to divide all the values on one of the columns except one.
I havent wrote any code about it just looking for an explanation on how to do it, if anyone could help out would appreciate.
In order to modify the content of one column in all rows except one, you can use the following query:
UPDATE tablename SET columName = columnName / 42 WHERE rowId !=42;
WHERE contains the condition that has to evaluate to true, in order for the update to take effect. My example modifies all rows except for those whose rowId column contains the value 42.
