You mentioned "visual foxpro" in your initial post.

Is your visual foxpro frontend accessing simple (DBF)

or compound "foxpro native" databases?

If you can get the xBase data to the server, then you could use OPENROWSET, OPENQUERY to directly read the DBF data in T-SQL.

I use T-SQL & COM to...

Could this help....

-- Make Test "Data"

Select 1 as Num, 'Abc' as Data into #Temp

UNION ALL SELECT 1, 'xyz'

UNION ALL SELECT 1, 'PQr'

UNION ALL SELECT 2,...

Create Procedure sp_B as

Insert into #Temp Select 1

go

Create Procedure sp_a as

Create Table #Temp (ANumber Int)

Exec sp_B -- puts a rec in #Temp...

Create a #Temp table in sp_A, then fill it up in sp_B.

Sorry about that, I did not take the time to make the sample table(s)....

anyway...

Select TheLatest.project_code, Previous.launch_date as Previous, TheLatest.launch_date as Latest

From (Select project_code, Max(launch_date) as launch_date ...

I do not completely understand

Please clarify.

Is there a way to create a single user, non logging database that can be used for "temp" operations?

Something like...

Declare @sql varchar(1000)

SET @sql = 'Create Database...

What happens if you...

Select SUM( ROUND(TheFloatCol, 5) )....

Here is a quick (maybe inefficient) possibility...

Select TheLatest.project_code, Previous.launch_date , TheLatest.launch_date

From (Select project_code, Max(launch_date) as launch_date

from [Table] A Group by project_code) TheLatest

join (Select project_code,...
