Question : SQL query
I am writting a SQL query. Below is the sample table. The result i want is for each customer, difference of sum of by and sum of sell.
Table:
customer trtype amount
0001 by 10000
0001 by 2000
0001 by 500
0001 sl 3000
0001 sl 2000
0002 by 60000
0002 by 4000
0002 by 500
0002 sl 3000
0002 sl 2000
example:
0001 : (10000+2000+500) - (3000+2000) = 12500-5000 = 7500
0002 : (60000+4000+500)-(3000+200
0) = 64500-5000 = 59500
Result should be
0001 - 7500
0002 - 59500
