All SQL Folks...
The original script has MAJOR error....
--In PART2 --- where it runs to update the growth table...it tries to convert the DATE to CHAR...and then compares with GetDATE() -- which is not correct.
--- I have corrected the script...BELOW>..replace the script code with Following for your EXISTS condition....This works good for SQL 2000....Change your EXISTS condition accordingly for 2005 script too..
-PART 2 -- CORRECTED EXISTS Section below...Replace on original script.;-)
...
...
If Exists (Select Distinct DBName from #TempDBSize2
where DBName in (Select Distinct DBName from DBGrowthRate))
and GetDate() > (Select Distinct Max(MetricDate) from DBGrowthRate)

How do you get it to insert rather than update? I want to keep track of the changes in size weekly...

All...
I have corrected the code..As it has flaws dealing with date comparison...And hence you are not getting the GROWTH amount on weekly runs...
Here is the UPDATED code (works for 2005, 2008)....Also, I have converted the GrowthAMT to Numeric (instead of VARCHAR), --- Allowing you to export the results in EXCEL for further number crunching
Let me know if this works for your environments.

even it was not working for me too. as it is showing 0 mb growth rate.

Hi Dave J,
Thanks a lot for the script...
The script provides the current Db size. but I would like to know is there any way that we can store the the DB size details for our future reference. That will help us for capacity planning
Regards,
Gokl
