I'm very new with talend. I want that talend updates data from excel into my db because of mistyping. For example I have columns year, name and number.
In the first run of my job in talend the excel data gets into my db. In the second run now I want that just the data with e.g. the same year (1. run: name= smith, year=2010, number=5; 2. run: name=smith, year=2010, number=6 get updated because I mistyped in excel. I don't want that talend truncate my table but steadily continue my table in the db every time I run the job. Sorry for my english and thank you for answers.
