Hi,
I have a question concerning the xxxTransactionValidate procedure within the SDO.
I need a "direct" database access to get the last record - because the last record have effects to the actual record.
So can I make a FIND LAST ... to a buffer within the beginTransactionValidate procedure?
And does this also work within SingleTier environment (with applicationServer)????
I wrote (long time ago), that the sdo´s transactionValidate statements are executed against the database - ist this right

Thanx
andi

Andi,

The TransactionValidate procedures run on the server-side section of your SDO. So, to answer your question, yes you will have access to the database in a distributed environment. You will need to be careful when you choose which TransactionValidate procedure you use, depending on what you're trying to achieve.

I'm hoping that I'm reading your question correctly, because there wouldn't be an appserver involved with a single-tier system. Do you mean n-tier?

Hope this helps,

Andy Smith
