Join two sql queries
SELECT Activity, arat.Amount "Total Amount 2008", abull.Amount AS "Total Amount 2009"FROM Activities aLEFT OUTER JOIN ( SELECT ActivityId, SUM(Amount) AS Amount FROM Incomes ibull GROUP BY ibull.ActivityId ) abullON abull.ActivityId = a.ActivityIDLEFT OUTER JOIN ( SELECT ActivityId, SUM(Amount) AS Amount FROM Incomes2008 irat GROUP BY irat.ActivityId ) aratON arat.ActivityId = a.ActivityIDWHERE a.UnitName = ?ORDER BY Activity
I would just use a Union
In your second query add the extra column name and add a '' in all the corresponding locations in the other queries
Example
//reverse order to get the column namesselect top 10 personId, '' from Telephone//No Column name assigned Union select top 10 personId, loanId from loan
