Restrictions on transaction management
                     
                   
                
             Restrictions on transaction management are as follows:
            
               
                  - Savepoints are not propagated to remote servers.
- If nested BEGIN TRANSACTION and COMMIT TRANSACTION statements are included in a transaction that involves remote servers,
                     only the outermost set of statements is processed. The innermost set, containing the BEGIN TRANSACTION and COMMIT TRANSACTION
                     statements, is not transmitted to remote servers.
