i have an scenario where I am sending data from jdbc adapter(oracle DB) to RFC ,now it is asynchronous,the problem is zhe sender adpter may updater more data than we want ,
my sender adapter :
the query sql ---- 'select * from ztable where flag = 0',
update sql ------''updater ztable set flag = 1 where flag = 0
firstly execute the query sql,at the same time new data with flag = 0 were putted in the table,but i dont get it,and then secondly,execute update sql,make its flag back 1,and I will never get it .
what can i do to solve this problem? make the interface synchronous ? .
thank you very much~
