我如何计算使用wordpress从sql查询返回的行数？

Question

I am currently using:

$dup_donor_count = count($wpdb->get_results("SELECT * FROM ".$table_name." WHERE Donor = '".$donor."'"));

which is giving me back '61', the total number of elements in the entire array, the array is an array of std objects, each of which is a row corresponding to my specified query, namely, where the Donor column is equal to 'Dave'.

There are 6 instances where this is true, how would I return this number (6) and not 61?

This is driving me nuts.

$wpdb->get_results("SELECT FROM ".$table_name." WHERE Donor = '".$donor."'");

echo $wpdb->num_rows;
