Hi I am running the following query in access query builder. The name of the query is "qryTempRecEFTB ankedMaxDate": - SELECT Max(qryTempRecEFTBanked.Dt) AS MaxOfDt
-
FROM qryTempRecEFTBanked;
-
it returns a date which exactly what I wanted, but when I run this code in VBA: - strSqlMaxDate = "qryTempRecEFTBankedMaxDate"
-
rst.Open strSqlMaxDate, cnn, adOpenDynamic, adLockOptimistic
-
With rst
-
If rst.EOF And rst.BOF Then MsgBox "The recordset is blank"
-
dtBankMax = !MaxOfDt
-
End With
!MaxOfDt returns as Null, even though rst.EOF = false and also rst.BOF = False. I don't know whether it helps but "qryTempRecEFTB ankedMaxDate" is based on the query "qryTempRecEFTB anked" the Sql for "qryTempRecEFTB anked" is as follows: - SELECT Sum(tblBank.Amount) AS SumOfAmount, tblBank.Dt, Val(Right(nz([SerialID],0),1)) AS ConsID, nZ([RecID],0) AS ReconID, tblBank.Desc
-
FROM tblBank LEFT JOIN tblReconciled ON tblBank.BankID = tblReconciled.BankID
-
GROUP BY tblBank.Dt, Val(Right(nz([SerialID],0),1)), nZ([RecID],0), tblBank.Desc
-
HAVING (((Sum(tblBank.Amount))<>0) AND ((tblBank.Dt)>#6/30/2008#) AND ((Val(Right(nz([SerialID],0),1)))=4 Or (Val(Right(nz([SerialID],0),1)))=5 Or (Val(Right(nz([SerialID],0),1)))=7) AND ((nZ([RecID],0))=0) AND ((tblBank.Desc) Like "*HANDYWAY*"))
-
ORDER BY tblBank.Dt;
-
Many Thanks

Can't see much wrong there :(
Check out the rst.Open (line #2) for correct parameters, and make sure that rst is defined as DAO.Recordset if you need that or ADODB.Recordset otherwise.
It could simply be the .Open line not working as expected. Check it out in the debugger ( Debugging in VBA).

Just a thought.
Could it be synchronization problem?
Did you try to use MoveLast method to force record fetch in recordset object?
Did you try to break the code execution after recordset has been opened and:
a) run code in step mode?
b) inspect rst variable in Watch window?

Fish.

I don't know if you overlooked my earlier post, but checking up from work (where I now have easier access to the information required) it seems that the Open method is a specifically ADODB.Recordset method. This means that unless your rst variable has been defined as ADODB.Recordset (We can't tell as you haven't shared this information) this code will not work (as Access uses DAO generally by default - at least in the older versions). DAO & ADODB do behave differently. ADODB will have different characters for wildcards for instance. This will behave in a different way from the way you would expect Access to behave (For the standard Access ways use DAO).
When I checked the Help system for the Open method of an ADODB recordset the first parameter (Source) did not list a QueryDef as a possible value. Do you have any reason to suppose this is working as you intend?
Hi
Okay there are 2 posts I would like to attention Post 7 and Post 6:
Post 7:
"...This means that unless your rst variable has been defined as ADODB.Recordset (We can't tell as you haven't shared this information)... "
A: Please see line 2 of the code in Post 4, it shows that the rst variable has been defined as New ADODB.Recordset .
Post 6:
Q:Could it be synchronization problem?
Did you try to use MoveLast method to force record fetch in recordset object?
A: I used the query which "qryTempRecEFTB ankedMaxDate" is based on. The name of the query I used is "qryTempRecEFTB anked" (see post 1 for the Sql) but even before I could use the .movelast function, it was coming up as an empty recordset I.E. rst.bof =True and rst.eof =True.
Then I tried to use the actual Sql code but it is giving me the error "Query does not include xxx as part of an aggregate function"
My code is as follows: -
Public cnn As ADODB.Connection
-
Public rst As New ADODB.Recordset
-
Private Sub cmdMaxDate_Click()
-
strSqlMaxDate = "SELECT Sum(tblBank.Amount) AS SumOfAmount, tblBank.Dt, " & _
-
"Val(Right(nz([SerialID],0),1)) AS ConsID, nZ([RecID],0) AS ReconID, tblBank.Desc " & _
-
"FROM tblBank LEFT JOIN tblReconciled ON tblBank.BankID=tblReconciled.BankID " & _
-
"GROUP BY tblBank.Dt, Val(Right(nz([SerialID],0),1)), nZ([RecID],0), tblBank.Desc " & _
-
"HAVING ((((Sum(tblBank.Amount)) <> 0) And ((tblBank.Dt) > #6/30/2008#) And " & _
-
"((Val(Right(nZ([SerialID], 0), 1))) = 4 Or (Val(Right(nZ([SerialID], 0), 1))) = 5 " & _
-
"Or (Val(Right(nZ([SerialID], 0), 1))) = 7) And ((nZ([RecID], 0))=0) And ((tblBank.Desc) Like '* HANDYWAY *'))) " & _
-
"ORDER BY tblBank.Dt;"
-

-
