You must also set the classpath to include the sqljdbc4file.
What I have been taught is to create a connection object, from which I create a statement, and then create a result Set from that using a string containing an SQL query.If you are not sure or don’t know exactly the index of column, so passing a column name would be useful: String sql = "UPDATE Users SET password=? I have quite a few examples on this website, just see the "Related" section for those.The value is casted to a String because we know that the username field is of type VARCHAR based on the database schema mentioned previously. "; Prepared Statement statement = conn.prepare Statement(sql); String(1, "123456789"); String(2, "William Henry Bill Gates"); String(3, "[email protected]"); String(4, "bill"); int rows Updated = statement.execute Update(); if (rows Updated String sql = "DELETE FROM Users WHERE username=?
Keep in mind that the column index here is 1-based, the first column will be at index 1, the second at index 2, and so on. To update the SQL tables, I was shown to use code like this: Result Set rset = stmt.execute Query("select * from airline_agents"); rset.update Int(1,1); rset.update String(2,"Agent 2"); rset.insert Row(); To add a new row we put To Insert Row() before this code.
