https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=33081 --- Comment #1 from Janusz Kaczmarek <januszop@gmail.com> --- In 22.11, apparently after applying bug 31314 (perhaps in conjunction with Bug 31306), placing a hold (from OPAC: opac-reserve.pl) on a serial record (i.e. a MARC 21 record with 942 $s set) generates runtime error and produces in opac-error.log the following info: DBI Exception: DBD::mysql::st execute failed: Column 'biblionumber' in where clause is ambiguous It seems that this is caused by the presence of 'serialid.publisheddate' in the line: order_by => [ 'serialid.publisheddate', 'me.enumchron' ] in Koha::Items::search_ordered. -- You are receiving this mail because: You are the assignee for the bug.
