Problem with this statement:
sSQL = "SELECT * FROM Projects;"
Set oDbe = CreateObject("D AO.DBEngine.36" )
oDbe.SystemDB = "myworkgrupfile .MDW"
Set oWS = oDbe.CreateWork space("", "me", "")
Set oDB = oWS.OpenDatabas e("mydb", , True)
Set oRs = oDB.OpenRecords et(sSQL)
Debug.Print oRs.RecordCount
It only returns 1 record.
But if I change this line to
Set oRs = oDB.OpenRecords et("Projects", dbOpenTable),
I get all my records. What is it about this db that would cause this?
thanks,

RecordCount is not the number of records in a recordset, it is the number of
records that have been read from the recordset. It will only be guaranteed to
equal the number of records returned after a .MoveLast.

Well, it can only be guaranteed to be accurate after a .MoveLast --
it may very well be accurate before that point:
1. if the recordset returns 0 records, the recordcount will always
accurately reflect that, even without the .MoveLast.
2. if there is only one record, it will be correct.
I don't rely on .RecordCount for anything except to see if there
are records returned by a recordset. If I want a count of records,
I do a Count() query.
It's only occasionally that I'll open a recordset for one purpose
and also use it to get a count of records. And that's only when I'm
using the recordset for some other purpose already.

Thus, my use of "only guaranteed to be". Of course, not knowing if its

If the recordset is a non-forwardonly snapshot (meaning it's a result suitably
small for a snapshot), I'll often use it for counting as well as for reading
rows. That's about the only time. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

The Object class has five non final methods namely equals, hashCode, toString, clone, and finalize.
These were designed to be overridden according to specific general contracts. Other classes that make use of these methods assume that the methods obey these contracts so it is necessary to ensure that if your classes override these methods, they do so correctly.
In this article I'll take a look at the equals and hashCode methods.

For Each tdf In dbs.TableDefs

it prints the correct name but the RecordCount is off on 8 out of 30
