Are there any method where I can upsert into a SQL datawarehouse table ?
Suppose I have a Azure SQL datawarehouse table :
col1 col2 col3 
2019 09 10
2019 10 15

I have a dataframe 
col1 col2 col3
2019 10 20
2019 11 30

Then merge into the original table of Azure data warehouse table 

col1 col2 col3
2019 09 10 
2019 10 20 
2019 11 30 

Thanks for everyone idea
