[EP-tech] Re: Possible bug in title_duplicates script?

[George Mamalakis]

Ah,

And of course the obvious solution would be to change the location of 
the first AND statement, so a patch similar to this:

     $sql .= " $Q_eprint_status=" .  $db->quote_value( "archive" ) . " 
AND ";

      $db->sql_LIKE() .


Before opening a bug report in EPrints' github, please someone do 
confirm that what I'm suggesting is not breaking things instead of 
fixing them.

Cheers,

George.
