Hi,
What is the correct syntax for updating an "existing" field in an SQL Table.
If Exist Update Else Insert
At the moment I am fetching the entire table from the Database and loop through all the rows and compare to the new data, which I would imagine will eventually slow down the application as database grows.
Thanks,
Aris

This is NOT a MATLAB related question. You have to check SQL syntax: http://www.w3schools.com/sql/sql_update.asp
