Merging SELECT statements

Hi,

There is probably a simple solution to this but I need to resolve very urgently. Unfortunately I'm not too good with SQL!

I have a T-SQL query for SQL 2008

DECLARE @thismonth varchar(7)

SET @thismonth = CONVERT(varchar(4),GETDATE(),120) + '-' + CONVERT(varchar(2),GETDATE(),101)

SELECT [Target] AS [Budget GP] FROM dbo.tblTarget
WHERE [SalesChannel] = 'HR' AND [Period] = @thismonth

SELECT
SUM(ISNULL(CASE WHEN [Trx Type]='credit' THEN (GP * -1) WHEN [Trx Type]='invoice' THEN (GP) END , 0)) AS [Billing] , 

SUM(ISNULL(CASE WHEN [Trx Type]='booking' THEN GP END , 0)) AS [Booking] 

FROM  dbo.tblTransactions 

WHERE [Sales Channel] = 'HR' AND [Doc Date YYYY-MM] = @thismonth

Open in new window

How can I merge the two select statements into one so I see the Budget / Billing / Booking columns in the same result?

Thanks

SELECT Target AS 'Budget GP', SUM(ISNULL(CASE WHEN [Trx Type]='credit' THEN (GP * -1) WHEN [Trx Type]='invoice' THEN (GP) END , 0)) AS 'Billing' , SUM(ISNULL(CASE WHEN [Trx Type]='booking' THEN GP END , 0)) AS 'Booking'
FROM dbo.tblTarget T1
INNER JOIN dbo.tblTransactions T2
ON T1.SalesChannel=T2.SalesChannel AND T1.Period=T2.[Doc Date YYYY-MM]
WHERE T1.SalesChannel='HR'

Something like this? Notice that, because of the INNER join, if there are no matches between the two tables, you won't get results. To get them, you'd need a LEFT, RIGHT or FULL OUTER JOIN.

You dont need merge ... what you need is join for two select statements

Can you paste the results for both of your select statements?

One thing I forgot, since you're using SUM for two of the fields, you'll have to add:
GROUP BY Target

Thanks all!

Cluskitt's solution worked (once the GROUP BY clause was added). I needed to change the line ON T1.SalesChannel=T2.SalesChannel AND T1.Period=T2.[Doc Date YYYY-MM] to ON T1.[SalesChannel]=T2.[Sales Channel] AND T1.Period = @thismonth AND T2.[Doc Date YYYY-MM] = @thismonth as it was showing all targets and sales info rather than for the current month. But it works so thanks for your help as it got me out of a jam!

You should leave the on clause as it was. It was my bad that you should have added:
AND T1.Period=@thismonth
to the WHERE clause (you could also compare to the doc date. Either would be fine but only one is necessary because of the join).
