Hi Paul,
Thanks very much for this. Your query actually helped me to identify my syntax problem. I was using "IS NOT NULL" in my WHERE clause, which includes the XML for 001, when I should have been using "= 0", as in:
SELECT biblionumber FROM biblioitems WHERE EXTRACTVALUE(marcxml,'//controlfield[@tag="001"]') = 0
The above query successfully returns all biblionumbers with no 001s.
Perhaps accidental serendipity? It's highly unlikely that you have any 001s with 0 as value, so it works... In fact my query looks for the COUNT, so "= 0" (no records) can be replaced by "> 1" and find duplicate records ;=} Warmest regards -- Paul
Thanks for your time on this!
All best,

Hi all,
Koha 16.05 o Ubuntu 14.04 LTS Package install
Would a kind soul help me with a basic SQL report which compiles a list of all bibliographic records that have a blank 001, but which have a biblionumber? Columns selected for the report = biblionumber, title, author.
I have tried a number of queries but can't seem to get the syntax correct.
We have one that just gives you "clickable links" to allow editing the biblio:
SELECT GROUP_CONCAT('<a target="_blank" href=\"/ cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=',biblionumber,'\">',biblionumber,'</a>' SEPARATOR ', ') AS BibNums, EXTRACTVALUE(marcxml,'//controlfield[@tag="001"]') AS Id FROM biblioitems GROUP BY Id HAVING count(Id) = 0;
Best -- Paul
