Hi!
Orders are in table
create table order (
dokumnr int primary key,
packno char(10)
);
insert into order dokumnr values (123);
One user sets pack number using
update order set packno='Pack1' where dokumnr=123
3 seconds later other user retrieves pack number using
select packno from order where dokumnr=123
However, other user gets null value, not Pack1 as expected. After some time later, correct value Pack1 is returned.
How to get updated data from other user immediately?
3 seconds is long time, it is expected that select suld retrieve update data.
There are lot of transactions running concurrently. Maybe update command is not written to database if second user retrieves it.
How to flush orders table so that current results are returned for second user select ?
