Thanks for your help. You code works but it should read l.key1 = c1.key1 and l.key1 = c2.key2 (the child table doesn't contain a code field).
Now I do want to display records from the master table that have no child entry or only have one child put I can't quite seem to figure out the right places to put the (+) signs.

Good catch. I thought it was odd that the code would be in the child table, too. Guess I got ahead of myself when writing the SQL. It's kinda hard to write that stuff when you don't have the tables to play with in front of you.
The plus sign represents an outer join. You typically do an outer join to a foreign key column that might be null. So, since the p.code column is the primary key, that comparison should be p.code = l.code(+). I don't think you need one on the key comparisons. If so, they probably go on the l.key1 column. I'd have to play with it to be sure.
Also, just to make things easier on people who read your SQL, I'd suggest you put the outer join columns on the right side of the operator. Not that it's a huge deal, but I personally find it a bit easier to read that way. Maybe that's just because it's the way I'm used to it, tho.

First of all: HAPPY NEW YEAR TO YOU ALL.
The following code executed ONCE and it works just fine. But it fails for subsequent calls, given the following error msg: “No Transaction in Active”.
Private Sub Update_Account()
Dim T_OwnRec, A_OwnRec, P_OwnRec As Boolean
T_OwnRec = Data.Get_TCount
A_OwnRec = Data.Get_ACount
P_OwnRec = Data.Get_PCount
Try
'****ERROR
Data.Con.BeginTrans()
'****ERROR
If Update_All(T_OwnRec, A_OwnRec, P_OwnRec) = True Then
Data.Con.CommitTrans()
Trigger_Thread2LoadTags()
Else
Data.Con.RollbackTrans()
MiniMe = False
MsgBox("The Account could not be updated!!!", MsgBoxStyle.Information, "Unexpected error at:" & t_Str)
MiniMe = True
End If
Catch
Data.Con.RollbackTrans()
Handle_Error(Err, "Update_Account")
End Try
End Sub
The error is generated at the "Data.Con.BeginTrans". CAN ANYBODY OFFER SOME HELP. THANKS A LOT GUYS/GIRLS

I'm confused. What technologies are you using?

I am "trying" to code using VB.Net and ADO.

That's what is confusing. ADO.NET has BeginTransaction, not BeginTrans. (I'm assuming SQL Server on the back end, because you didn't fully answer my question)

Hi Guys, first of all Thanks for offering help. I found out what was causing the error (still do not understand why). The three top variables are being loaded by running queries and each function is supposed to return TRUE/FALSE (they do). I understood that Local Variables (within subs or functions) were automatically disposed off, once the focus leaves the sub or function. But my Local Recordsets are not being disposed off, and for some reason that goes beyond my little knowledge is preventing me from starting a Transaction.
this is weird. Because I am not hardcoding the dispossal of any of my local variables at all, and this is the only piece of code that generates this error.
Once again. Thank you guys for offering your help. HAVE A VERY HAPPY NEW YEAR.

Check the state of the connection. A transaction cannot be initiated with the state of the connection other than OPEN.
Happy new year to all of u

Unfortunately the Connection is OPEN, I am able to execute other commands through my app.

ADO.NET does not have recordsets. Classic ADO does. You should be using ADO.NET. This may be an incompatibility issue.

As Colin said, you should be using ADO.NET, not classic ADO. The reason your recordsets are not being disposed is that they are not managed objects, but wrappers around COM objects (whose lifetime you must manage yourself). ADO.NET is supported by the System.Data.Oledb namespace in .NET.

What do u mean by recordset here. Is it traditional recordset of ADO or u r talking abt DataReader of ADO.Net.
Plz give the details of "Data" or atleast "Data.Get_TAccount"

PASCAL? Do you mean Delphi or TurboPASCAL? In tp it is imho impossible. With Delphi Prof you can use Access-DBs with die ADO-components.

aspnet_22 wrote: do you mean we can use delfi utilities in tp7
No, you can't do this. If you want to use PASCAL buy Delphi 2006 or if you prefer PASCAL for .NET u should buy VS2005 >= standard (standard, prof, team suite) and Chrome 1.5[^].

Isn't that what the query optimiser in SQL Server already does?

Could you elaborate on what you need? Mr. Mackay's advise is probably the best. Only other optimization tool that could work, according to Michael Abrash's Zen of Code Optimization, is right between your ears

No problem about opinion, which we all are entitled to as humans. However, be careful about trying to teach someone about professionalism when you wrote:

I guess if this does not say it all then I am asking the wrong people.
But since I've googled and Dave googled and no results came up that sounds like what you are looking for, then maybe you could come up with a tool that suits your requirements and share with your fellow IT professionals (whether it be by FEE or FREE).
Happy coding

After Googling for this for about 30 minutes, what you want doesn't exist.
All I found were tools that do the same thing that the Analyzer does in 2005.
