hahaha the windows sound at 5:52 scared me!! well explained video though thank you
Great. Nice & simple explanation..!
Thank you...
Please upload video on CDC.
Cmg soon!!
It doesn't seem too efficient to keep updating all rows... In source table you should have a column: RevisionDate and set a trigger on this to auto update. Then filter on this column.
and if you dont have any column modified date, you can compare all columns with except command of sql ? do you have any better idea for me :) ?
Please put a video on : How do we add parameter for the ADO source, like using variables to filter the records. select * from table1 where date > ? I am connecting to a DB2 source and retrieving data, it already got 20million records on it, i just what to upload it incrementally on last modified date. need to query the DB2 using the date modified.
super well explained
Thank you..
Love it!
Thanks a lot..
Thank you for this informative video. Can you also explain how we could create Fact Table by extracting data from DB after generating this dim packages?
Thanx..Fact table generation is the time consuming one.. will do one soon along with different deployment ways..
Error: OLE DB error occurred while populating internal cache. Check SQLCommand and SqlCommandParam properties.". I get this when i execute, should i execute DROPCLEANBUFFERS and if so will this create any data loss.
Hope you have figured it out by now. I would need to chat in detail on this or you can do delete insert rather than update.. let me.know if you need a video on this.. I can upload one..
Also consider cleaning cache like yours aid if it's your local host.. if its upper environments avoid that, as those may be from other parallel processes
but the update will keep updating all the records rite whether there is any modification or not ?
What program did you use to draw the flow chart?
How to if i use ODBC Destination pls?
Create odbc connection manager use that in destination. Make sure the ETL deployment server has the ODBC for this destination as well
@@dataexplained7305 but u used ole db command for updating, how to use that in case odbc destination?
