Hello All,
I have a column( Alert_Key) which needs to be populated as a sequence generator .The detail requirement is below.
1) If a key is generated then it should not be generated again.
2) Jobs are running parallel and each job will load key into the alert_key column.
3) Before loading the key ,it needs to checked if the key is there ,if so it should generate a unique key.
Many Thanks In Advance,
Sandeep.o
