Sum two results from SQL query - sql

Question

I just started learning SQL. I filtered the data I have and accordingly two results came out. I want to collect these results, but whatever I do, it throws an error.
Here is my code:
SELECT TOP (1000) [Sec_id]
,[Prc_date]
,[Mkt_Price]
,[Currency]
,[Pricing_factor]
FROM [EXAMPLE1].[dbo].[market]
WHERE Currency='INR' OR Currency='AUD';
SELECT SUM(Mkt_Price)* Pricing_factor as INR FROM market
where Currency='INR' and Mkt_Price>100 group by Pricing_factor ;
SELECT SUM(Mkt_Price)* Pricing_factor as AUD FROM market
where Currency='AUD' and Mkt_Price>100 group by Pricing_factor ;
SELECT SUM(Mkt_Price)* Pricing_factor as totalll FROM market
where Currency='AUD' or Currency='INR' and Mkt_Price>100 group by Pricing_factor
and I got these results:
How can I collect(SUM) and reflect the resulting data ("INR"," AUD")? (Using SMSS)

Answer 1

SELECT Currency, SUM(Mkt_Price * Pricing_factor) AS Total
FROM market
WHERE Currency IN ('AUD', 'INR') AND Mkt_Price > 100
GROUP BY Currency;
Be careful with operator precedence:
Currency = 'AUD' OR Currency = 'INR' AND Mkt_Price > 100
Currency = 'AUD' OR (Currency = 'INR' AND Mkt_Price) > 100 -- same thing
This is what you really wanted:
(Currency = 'AUD' OR Currency = 'INR') AND Mkt_Price > 100
To combine the totals with a grand total you could try a union:
SELECT Currency, SUM(Mkt_Price * Pricing_factor) AS Total
FROM market
WHERE Currency IN ('AUD', 'INR') AND Mkt_Price > 100
GROUP BY Currency
UNION ALL
SELECT 'All', SUM(Mkt_Price * Pricing_factor) AS Total
FROM market
WHERE Currency IN ('AUD', 'INR') AND Mkt_Price > 100;
One you progress past understanding the basic operations you'll want to check into "grouping sets" and "rollup".
