Question : SQL Query
Hello,
Have a table that is based on a report - it creates a record for each new version of the report so you could conceivably get 1 - 10+ versions of a report. I need to eliminate all the older versions and show just the most recent. The table is set up as:
Report_Amendment
Report_Root_ID (original (first)report created)
Report_New_ID
Report_OLD_ID
CREATED_DATE
ex of data below:
46 47 46 2009-04-16 09:37:33.123
46 48 47 2009-04-16 09:38:13.477
46 1167 48 2009-08-03 13:29:53.653
So I want to isolate just the most recent record but my query below does not do this, it gives me all the records except the first - I`ve tried several things but am not sure that I am thinking about this logically - can anybody give me direction...Thank you
SELECT dbo.Report_Amendment.Repor
t_Root_ID,
dbo.Report_Amendment.Repor
t_New_ID,
dbo.Report_Amendment.Repor
t_OLD_ID,d
bo.Report_
Amendment.
CREATED_DA
TE
FROM dbo.Report_Amendment
WHERE dbo.Report_Amendment.Repor
t_OLD_ID <> dbo.Report_Amendment.Repor
t_Root_ID
AND dbo.Report_Amendment.Repor
t_Root_ID = 46
GROUP BY dbo.Report_Amendment.CREAT
ED_DATE,db
o.Report_A
mendment.R
eport_Root
_ID,
dbo.Report_Amendment.Repor
t_OLD_ID,d
bo.Report_
Amendment.
Report_New
_ID
HAVING dbo.Report_Amendment.Repor
t_New_ID = MAX(dbo.Report_Amendment.R
eport_New_
ID)
Answer : SQL Query
hmmm...not really. what are you concerned of? it should be a descriptive name, but you can always use restore filelistonly to get the logical names in the backup.
