may be you can use IN clause:
SELECT SUM(price)*0.5 AS price1, SUM(price)*0.65 AS price2 FROM table
WHERE partner IN ('A', 'B');

Because these are two quite distinct queries, I don't see an immediate way of
joining them that would make them more efficient. Something that comes to mind
are sub-select statements for example, but that would make this more complex
than it needs to be.
Like Robert said, you aren't giving us
What I'm looking for is to SUM the price from partner A and B with each
result. So the result I expect is like "Partner A total's price 123,
Partner B total's price 456". Can you give me the query example? TIA.

It's not clear what exactly you are looking for. Two possible solutions:
1) use a union
2) use a join with another table containing partner and factor fields.
Can you give a short example of what the input looks like and what you
would like the output to look like?

On Thu, S
I have these query:
SELECT SUM(price)*0.5 AS price1 FROM table WHERE partner = 'A';
SELECT SUM(price)*0.65 AS price2 FROM table WHERE partner = 'B';
Is it possible to make the queries into 1 single query? How to make it
happen? Many thanks for helps.

You can do this using a variable. Set the variable starting value with
a "query":
set @runningTotal := 0
Then add the calculation to your total:
SELECT a. trans_id ,a.tran_date,b.cat_type,a.payee,a.amnt,
@runningTotal := @runningTotal+a.amnt AS rollingTotal from
transactions a join categories b on
Hi,
Hoping someone can help me with this little issue! It seems really
simple but my brain is refusing to work.
We have a transactions tables like so...
mysql> desc transactions;
+---+--+--+-+-++
| Field | Type | Nul
Well said Darren. Its not magic :)
Christos, you can download and run mysqlreport from
http://hackmysql.com/mysqlreportguide
it will give you more idea about DB serve performance.

Hi Christos,
Performance optimization is very subjective, and if you are experiencing low
performance it can be a million different things. The description you
provided didn't mention any of your current my.cnf settings, nor did it
mention what kind of tables your database contains, size of data,
