Am trying to append the data using replacement variables but when the query is run the result is not the corect one.
(eg)
Scenario 1:
Query used:
Select * from t1
where time_stamp>'!{lastvalue:time_stamp}!'
order by time_stamp asc
time stamp value is null for the first run and hence all the records are loaded
After the inital run ,i see the time_stamp value has been updated in the curent value column of the replacement variable which is the last value found in the table.
Now when i run the job am expecting the Query to return no rows but the entire data is returned and true duplicate data is appened.
Scenario 1:
Select * from t1
where time_stamp>'!{lastvalue:time_stamp}!'
order by time_stamp desc
time stamp value is null for the first run and hence all the records are loaded
Ater the first run i see the time_stamp value has been updated in the curent value column of the replacement variable which is the first value found in the table.
Now when i run the job am expecting the Query to return the entire data but there are no rows returned.
I find this logically incorect as
Select * from t1 where time_stamp> max_time_stamp order by time_stamp asc , should return any result..
I think this is a bug , please advise other wise.
My aim is to use the replacement variable to capture only the incremental records.
