JDBC INSERT with autonumbers

Here's the problem query:

int update = statement1.executeUpdate(
            "INSERT INTO diary(name,date,time,)
   VALUES ( " 
   + z.getName() + "','" + z.getDate() + "','" + z.geTime()")");

The problem is, in the database table diary preceeding 'name' there is an autonumber acting as the 'primary key', called diarykey.

What's the best way to include this in the query, because when i leave it out i get 'INSERT SYNTAX ERRORS'!

You shouldn't do. The problem is more likely to be with the way you're putting in the other params.

Which is not too surprising - you've reverted to your earliest code in http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_20805871.html. Why?

you are missing a ' before z.getName() ;

you have an extra "," after time

and you should use a preparedstatement;

Assiming all 3 fields are strings;

PreparedStatement ps = connection.prepareStatement( "INSERT INTO diary( name,date,time ) VALUES ( ?, ?, ? )" ) ;
ps.setString( 1, z.getName() ) ;
ps.setString( 2, z.getTime() ) ;
ps.setString( 3, z.getDate() ) ;
int update = ps.executeUpdate() ;

Ok, so I should have used a PreparedStatement, but the original problem
still remains.

If the first column in the table is an autonumber called diarykey how does this get handled?

Do you just ignore it from the java side?
