SQL Processing in a Page

From a WordPress page. I want to be able to retrieve the Bible reference for a daily Bible reading from an SQL file I created that I will use to issue a call and format the data to be presented on the page. I have the call working with the passage parameter hard coded. The problem is I can’t get any code to access the SQL table I created.

To test the access to my table I am using the plug in insert-php to write the PHP code which is below.

[insert_php]

global $wpdb;

$myrows = $wpdb->get_results( “SELECT reading_date, reading_passage FROM 90DayGospelPlan” );

echo “my rows = ” $myrows;

[/insert_php]

When it runs I get nothing. I would appreciate it is someone would steer me in the right direction. Thanks in advance
