Question about sql in java?

Hello,

Could anyone offer some advise, about adding records to mysql using java.

I managed all the connection, and understand some sql. The database has two tables:

table author:
authid
lastname
firstname

table isbn:
authid
isbn

When adding values to these tables, since they are linked by the authid field. Could I use one insert statement to add values to both tables.

Or would I need to use two insert statements, one for each table?

Thanks

Something like this: the values are not added for the example.

Statement statement = connection.createStatement();
String query = "INSERT INTO author(authid, lastname, firstname)VALUES
statement.executeUpdate(query);

query = "INSERT INTO isbn(authid, isbn)VALUES
statement.executeUpdate(query);

yes, this looks like you have the right idea.

Statement statement = connection.createStatement();
String query = "INSERT INTO author(authid, lastname, firstname)VALUES
statement.executeUpdate(query);

query = "INSERT INTO isbn(authid, isbn)VALUES
statement.executeUpdate(query);

prepared statement would be better (probably), as it gets round people entering ' into strings...

int id = 1 ;
String lastname = "Yates" ;
String firstname = "Tim" ;
PreparedStatement s = connection.prepareStatement( "INSERT INTO author( authid, lastname, firstname ) VALUES ( ?, ?, ? )" ) ;
s.setInt( 1, id ) ;
s.setString( 2, lastname ) ;
s.setString( 3, firstname ) ;
s.executeUpdate() ;
