How to query for Double with Spring JDBC template query

Question

How do one query for a double with the Spring JDBC temple?

For example:

public double getAverageScore() {
    return jdbctemplate.queryFor???("select avg(score) from test");
}

There are queryForInt and queryForLong, but no queryForDouble

Answer 1

I haven't tested this, but queryForObject with Double.class as the last parameter might work.

public double getAverageScore() {
    return jdbctemplate.queryForObject("select avg(score) from test", Double.class);
}

Answer 2

public double getAverageScore() {
    return jdbctemplate.queryForObject("select avg(score) from test", Double.class);
}
