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.

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

Red places is repeat but I need just one of them in result.
Try using DISTINCT

i have only one row with a lot columns in my table. I want to select columns with values greater than zero.
WHERE (col_1 > 0) and ... (col_99 > 0)
It will be too long query, if i want to write all statements. Does it possible to write query with selecting columns with values > 0 ?
Bro flow the method its lengthy by works.
First you unpivot the data and select values where column value > 0
secondly Pivot again and you will get you desire result.

From the above table, I want to remove the rows that have the duplicate CODE column. Out of the duplicate rows, the row with the smallest ID_CHECK should be retained.
Output:
If I understand correctly, this should be your SQL query:
Select Names, Code, ID_CHECK
FROM
(
Select Names, Code, ID_CHECK,
ROW_NUMBER() OVER(Partition by Name,Code Order By ID_CHECK) as rnk
FROM table
)tmp
WHERE tmp.rnk=1;
Let me know if this works.
