SQL java get value assigned to auto increment primary key [duplicate]

Answer 1

Use Statement#getGeneratedKeys() and Statement#executeUpdate(String, int) (this is a JDBC 3.0 feature, your database has to support JDBC 3.0).

Here's an example that returns a ResultSet with values for auto-generated columns in TABLE1:

Statement stmt = conn.createStatement();
int rows = stmt.executeUpdate("INSERT INTO TABLE1 (C11, C12) VALUES (1,1)", Statement.RETURN_GENERATED_KEYS);
ResultSet rs = stmt.getGeneratedKeys();
