SQL java get value assigned to auto increment primary key

java, jdbc, sql

Solution

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();

Problem

I have a primary key auto increment attribute in my table. I want to know the value assigned to it for a row that is inserted using statement.executeUpdate(). How to achieve this in the best possible manner?
