Here is one approach I've used in the past. I think this will help you with the basics. I've only included 2 of the tables, adding the third should help you to understand the answer rather than copy/paste it.

(You'll need to change the first line to add references to sum(Costings), and add a 'union' 'select ... from bank_mobile_costing', in addition to adding a reference 'Costing' column to the 'Investments' and 'Earnings' select statements.)

select date,sum(Investments),sum(Earnings),sum(Investments+Earnings) as Balance from
select date,amount as 'Investments',0.0 as 'Earnings' from bank_mobile_investments
select date,0.0,amount from bank_mobile_earnings 

) mydata 
group by date
order by 1

It's worth my noting here that this will NOT display a list of calendar dates in the date column, but rather it displays a complete list of all the dates which exist in your 3 tables; I don't know if that's appropriate to your needs.

On the subject of your running total column at the end, this is a convoluted subject but a quick google search yields the following stack overflow result which gives a couple of methods of doing it, and there are some interesting points raised in the comments about the advantages or drawbacks of the methods.

  • Thanks for your quick response.. Before posting this problem.. I had try to resolve the problem from dba.stackexchange.com/questions/97773/… (solution of RolandoMySQLDBA) But I did not able to rearrange... It was perfect solution for me.... Can you please refix the Rolando query with my three table. KIndly appreicate
