INTERVIEW QUESTIONS DATA WAREHOUSING DATASTAGE DETAILS

Question: How can you do incremental load in datastage?

Answer: Incremental load means daily load.

when ever you are selecting data from source, select the records which are loaded or updated between the timestamp of lastsuccessful load and todays load start date and time.

for this u have to pass parameters for those two dates.

store the last rundate and time in a file and read the parameter through job parameters and state second argument as currentdate and time.
