Hi, I am finding hard to load data from CSV to DB. I have a table with composite primary key, say column B and A in (columns A,B,C,D). We need to import the file every month, and some of the data in file just need updates to DB and some of them are new. If composite primary key already present in DB, We need to update data to DB otherwise, insert them. Could someone help me with the insert/insert_update command ?
