Question

I am learning MySQL with JAVA, and don’t understand prepared statements. Abstracting from I shall learn it, I want to ask for help in finishing this code to be “prepared stated” 🙂

String stringQuery = "INSERT INTO banlist (name, reason, admin, time, temptime, IP) VALUES (testNick, testPowod, testAdmin, CURRENT_TIMESTAMP, NOW(), NULL);=?";

PreparedStatement statement = this.connection.prepareStatement( stringQuery );
statement.setString( 1,  ); // after ' 1, ' we define what we want to get
ResultSet resultSet = statement.executeUpdate(); 

Answer 1

String stringQuery = 
    "INSERT INTO banlist (name, reason, admin, time, temptime, IP)"
    + " VALUES (?, ?, ?, CURRENT_TIMESTAMP, NOW(), NULL)";

PreparedStatement statement = this.connection.prepareStatement(stringQuery);
statement.setString(1, testNick);
statement.setString(2, testPowod);
statement.setString(3, testAdmin);
int inserted = statement.executeUpdate();
