updating table RRS feed

  • Question

  • Suppose I have one hello.csv file in the data lake and I have created table inside the SQL database from that file.

    Now I made the copy of same hello.csv file and changed to the hello1.csv and add a row of extra data in that .

    now if I want to update the same table in SQL with only extra row from hello1.csv so how can we do it ? But it shouldn't truncate the table and put all the data again because if some table have millions of records then it will be a problem .  please help me
