i would like to do the following: there is a table in my database with several columns. i want to increase the value in one of them. Which one is not known, it depends on the value of one parameter of the function . i declare using preparedStatement.setString() which column is to be changed. My problem is that i dont know how to write the query so as to achieve this increament. something like update user_statistiks set ? = ?+1 where USER_ID = ? doesnt work.. the second questionmark is the problem.. does anyone know how i could write my query?
