Very helpful, good explanation and I can develop my incremental job now.
Great thanks
very useful
but in your case created_date and modified _date are same at the time of insert.Your are taking max of modified _date in context ,I think it should take max of max( modified _date) and max(created_date) .then only it will be 100 % perfect
Crisp and clear , Thanks for the Videos
Thank you very much
Very nice explanation 👍
This video save me Today.. Thanks :)
Hi Rohan,when do you start making videos?why did you stop making videos? it's helping alot for the learners.please make videos.

Thank you Rohan!!
Could you please create a job to compare two strings and get greater one?
Thank you..
Can you make a video to do incremental load using sequence key. Because surrogate key scenario will work for new records. How to handle updated records because for the the prod id value will not change.
what if we have only created_on row with modified_on as 'Null' on next day ?..It will assign 'Null' value to last_run context right ? How we handle such situation then?
Nice and helpful
Glad it is helping many!
very useful, How to get modified date..?
It’s the max date from table.. it’s covered in the video and you may want to check again.. thanks.
If it is possible to make video on Generic schema
If we didn't insert any dummy records in Target table then will it work? If not then how to handle that?
If dummy is not there, the first time data load will have issues. Alternatively You can try handling null value using nvl or case statements
@@LearningwithRohan Thanks will try this.
Hi, Rohan in my case my sap table has no Id, dates for max selection! How can we perform? delta load for sap to impala output.
You may want to request your sap source system contacts to include that info. It must be there but not exposed to etl. Sap tracks all history of changes
Please make a video on thmap and it's datamapper
Thmap is present only in the enterprise product.. it’s not in open studio
@@LearningwithRohan yes, but if possible make a video on it, it would be great help!! Thanks
