Hi, we just moved a database from SQL2000 to SQL2005 and for some reason, we are now getting a blank nested recordset. Here is the code:
SQLString = "SELECT rateID, startDate, endDate FROM Hotels_Room_Rates_Block WHERE roomID = 338 ORDER BY startDate"
recordSet.Open SQLString,,1
if not recordSet.EOF then
while not recordSet.EOF
SQLString = "SELECT a.netRate, a.markup, b.rateType, c.startAge, c.endAge FROM Hotels_Room_Rate a FULL JOIN AvailableRateTypes b on b.rateTypeID = a.rateTypeID FULL JOIN Hotels_ChildGroups c on c.childGroupID = a.childGroupID WHERE a.rateID = " & recordSet("rateID") & ORDER BY a.rateTypeID"
tempSet.open SQLstring,,1
Each recordset independently works fine if i put it into a query window. It's when I nest them like this that the second recordset (tempSet) is giving me an EOF problem. Any suggestions? The only variable that changed was moving from SQL2000 to SQL2005.
Thanks!

Hi David,
Thanks for your input, yes.. it was a copy/paste problem. It's actually correct in the code. I need 2 queries because recordset returns multiple rows and i need to be able to loop through the rows and pull the second recordset of rows based on the first. It's the stranges thing ever, because the code has worked fine for a year and we moved it to SQL2005 this morning and now it doesn't work. No errors, just no returned rows.
Thanks.
I was going through your query and there is a much better way to create this query in much more optimised and effiecient way using an OUTER JOIN.
SQLString = "SELECT RB.*, RR.netRate, RR.markup, RT.rateType, CG.startAge, CC.endAge FROM Hotels_Room_Rates_Block RB, Hotels_Room_Rate RR, AvailableRateTypes RT, Hotels_ChildGroups CG Where CC.childGroupID = RR.childGroupID(+) AND RR.rateID = " & recordSet("rateID") & ORDER BY RR.rateTypeID"
Let me know ;)

Hey AJKConcepts,
I don't see a problem with the code, except a missing " here:
& recordSet("rateID") & ORDER BY a.rateTypeID" should read:
& recordSet("rateID") & " ORDER BY a.rateTypeID"
Could just be a copy/paste error in your posting but just wanted to make sure! Make sure there's a space between the double-quote, and the word "ORDER".
Another suggestion/question - any reason why you don't simply use one query, by joining the nested query to the table referred to in the first query? Such as:
SELECT a.netRate, a.markup, b.rateType, c.startAge, c.endAge
FROM Hotels_Room_Rate a
FULL JOIN AvailableRateTypes b
ON b.rateTypeID = a.rateTypeID
FULL JOIN Hotels_ChildGroups c
ON c.childGroupID = a.childGroupID
INNER JOIN Hotels_Room_Rates_Block hrrb
ON a.rateID = hrrb.rateID
ORDER BY hrrb.startDate, a.rateTypeID
Let me know if either help - just some random thoughts, probably not a real solution!
Regards,
David.
