Hi,
I would like to list records by subject (in a SQL report).
I can isolate the first subject in a record with
ExtractValue(biblioitems.marcxml,'//datafield[substring(@tag,1,1) =
"6"][1]/subfield[@code>="a"]')
But then I need to perform a UNION DISTINCT with another SELECT addressing
the second subject (with 2 replacing 1 between square brackets above),
etc, when records can have a much larger number of subjects (MARC field
starting with 6).
Any suggestion?
Thanks,
Giuseppe.
