[Koha] Subtitles

[Paul]

Could some kind person please help with subtitles MARC 245$b in mysql reports?

We're trying to improve a fully functional script, but for a SELECT neither

[other things],biblio.subtitle AS Subtitle,[other things]
nor
[other things],biblio.remainderoftitle AS Subtitle,[other things]

appears to function (the second comes from the Koha Wiki which suggests 
that it was introduced in/after 3.2 having been dropped in v3.)  The 
"SchemaSpy" also appears to be silent on this field.

Many thanks - Paul
