Not working with CPT / Post_Id= 0

Dear Mister Sinaga,
i made a research to find the reason why i have search terms in my database which show the post_id=0 and i found this thread:

https://wordpress.org/support/topic/plugin-seo-searchterms-tagging-2-plugin-doesnt-work-properly-it-saves-post_id0-value

You are talking about a little trick to solve that:

But even the first line i am supposed to replace is not available in your file

You say i should look for and replace this:
$result = $wpdb->get_results( "SELECTmeta_value,meta_count,post_idFROM“.$wpdb->prefix.”stt2_metaORDER BYlast_modifiedDESC LIMIT ".$count.";" );

But the only line that comes close to it is:
$result = $wpdb->get_results( "SELECTmeta_value,meta_count,post_idFROM“.$wpdb->prefix.”stt2_metaWHEREpost_id!= 0 ORDER BYlast_modifiedDESC LIMIT ".$count.";" );

I am not good enough in PHP to estimate what to do now.
Can you please help?

regards axel
