Thank you Francescina.
Explanation:
table A,table B,table C.
First table A needs to be updated,then table B and then table C in sequence.
If any thing goes wrong at the stage of updating table B or C the whole updation process should rollback.
There by creating a transaction.
I know query properties in MS Access could be changed to transaction:yes.
But i wish to have the transaction to take place in said order and in DB and not in ASP-JScript/VBScript.
Is it possible?
