How to get query plan information from Postgres into JDBC

Question

I want to capture the cost numbers from the query plan you get when you \'Explain\' a query. Is there any way to get at this data inside of a Java ResultSet(or similar obje

Answer 1

An other example with PreparedStatement, this time.

Like this:

PreparedStatement preparedStatement = connection.prepareStatement("EXPLAIN (ANALYZE true , VERBOSE true , BUFFERS true)" +
                "SELECT * FROM Table");

ResultSet resultSet = preparedStatement.executeQuery();
while (resultSet.next()) {
System.out.println(resultSet.getString(1));
}

Or with a bind parameter:

PreparedStatement preparedStatement = connection.prepareStatement("EXPLAIN (ANALYZE true , VERBOSE true , BUFFERS true)" +
                "SELECT * FROM Player WHERE id = ?");

preparedStatement.setLong(1, 1);

ResultSet resultSet = preparedStatement.executeQuery();
while (resultSet.next()) {
      System.out.println(resultSet.getString(1));
}
