Question

SQL WHERE with Multiple conditions

Asked by: garysamuels

I have a SQL statement that is working:
sql = "select * from tblOrderDetail Where tblOrderDetail.DetailID = (select MAX(DetailID) from tblOrderDetail)"

I would like to add an additional condition, the OrderID field must match.
dim oid as Long
oid = Me.OrderID.Value

I have tried the following but it's not working;
sql = "select * from tblOrderDetail Where tblOrderDetail.DetailID = (select MAX(DetailID) from tblOrderDetail) AND tblOrderDetail.OrderID = ('" & oid & "')"

Any suggestions?

Syntax is correct. Kindly explain what you meant by not working either not fetching results or error while executing or ...

And try this one out..

select * from tblOrderDetail
Where DetailID = (select MAX(DetailID) from tblOrderDetail)
AND OrderID = ('" & oid & "')"

The following did not work. I'm getting the same run time error: Data type mismatch.
So, I assume it's a syntax error. Please note that the final variable (oid) is a Long data type.

Dim oid As Long
oid = Me.OrderID.Value
 
 
sql = "select * from tblOrderDetail Where DetailID = (select MAX(DetailID) from tblOrderDetail)AND OrderID = ('" & oid & "')"
 
Set currentDetail = CurrentProject.Connection.Execute(sql)

your query is right i m not seem any wrong in your query

 

by: harfangPosted on 2009-10-22 at 06:26:38ID: 25633868

oid is a long, so you want to write OrderID=123, not Order='123'. But that is not the real problem.

You select the last DetailID, and then filter for a given OrderID. If perchance the last detail belongs to the order you want, you are fine, if not, you get no record.

You want the last Detail for a given order. That would be:

SELECT TOP 1 * FROM tblOrderDetail
WHERE OrderID=123
ORDER BY DetailID DESC

Or, in VB:

    sql _
        = " SELECT TOP 1 *" _
        & " FROM tblOrderDetail" _
        & " WHERE OrderID=" & oid _
        & " ORDER BY DetailID DESC"

Good luck!

sql = "select * from tblOrderDetail Where DetailID = (select MAX(DetailID) from tblOrderDetail)AND cast (OrderID as char) = ('" & oid & "')"

 

by: rrjegan17Posted on 2009-10-22 at 08:05:48ID: 25635078

>> Data type mismatch.

AND tblOrderDetail.OrderID = ('" & oid & "')"

Why are you appending a single quote ' before and after your oid variable.
Single quotes before and after '1' makes this as a string instead of 1

Kindly remove single quotes and Open and Close braces so that it look like

AND tblOrderDetail.OrderID = " & oid

Perfect, thanks for seeing what I really wanted
