Making a view that shows the results of several different queries.

Hello,

I am trying to create a view that shows the following

Field1: Sum of Amounts from Table A
Field2: Count of Amounts from Table A

Field3: Sum of of Amounts from Table B
Field4: Count of Amounts from Table B
..
..
..
Field3: Sum of of Amounts from Table H
Field4: Count of Amounts from Table H
..
..
..
Things are a bit more complex but this is the gist.

I am using SQL 2000.

I know how to do this pretty easily using a stored procedure. But how
can I do it in a view? A SQL server won't meet my needs in this
situation.

I tried OpenQuery ('myserver', 'exec myprocedure') but get the message
that my server is not configured for data access. I tried the system
stored procedure to set data access to true but nothing seemed to
happen.

I also tried Select * from (

Select Statement1, select statement2

)

but got syntax error at the comma between statement1 and statement2.

Trying to use select Statement1 as ABC to does not seem to work either.

Is there a way to do what I want without making 15 views and then a
final view that shows them all together? I know I could probably do
something by creating a ton of functions, but it really seems this
should not be that hard...

I am definitely open to any easy suggestions!

Thanks,
Ryan

Hi Ryan,

This can be done in a single query. You can of course encapsulate that
in a view, stored procedure, or whatever.

To prevent double table-scanning, here's a query that will scan each
table only once:

SELECT Field1, Field2, Field3, ..., Field16
FROM (SELECT SUM(Amount) AS Field1, COUNT(Amount) AS Field2
FROM TableA) AS A
CROSS JOIN (SELECT SUM(Amount) AS Field3, COUNT(Amount) AS Field4
FROM TableB) AS B
.....
CROSS JOIN (SELECT SUM(Amount) AS Field15, COUNT(Amount) AS Field16
FROM TableH) AS H

(untested - see www.aspfaq.com/5006 if you prefer a tested reply)

Best, Hugo

I have tried what you suggested but it seems to snag with Syntax
errors. SQL accepts my Select .... AS A, B, C if I use it with the
Select * construct but it does not accept the CROSS JOIN STATEMENT

Select * FROM
(
SELECT count(Amount) as count1, sum(Amount) as sum1
FROM mytable1
WHERE x="1" and y="2"....
)
AS A

CROSS JOIN

Select * FROM
(
SELECT count(Amount) as count1, sum(Amount) as sum1
FROM mytable1
WHERE x="1" and y="2" and some other stuff....
)
AS B

Any ideas? I am not sure why the CROSS JOIN won't work actually. It
error out as soon as it hits the SELECT statement that follows CROSS
JOIN...

Hi Ryan,

You didn't use the correct syntax. Check my previous replly and compare
it carefully with your query.

Remove the line below!
