Additional Information

The Heading Query Options Setup screen allows for the maintenance of the Authority Query Options table (used when conducting searches in the Authorities module.) Any 'suitable' Tag (for example: a Marc Tag defined as an Authority) may be used as an enquiry point.

COLUMN HEADING

EXPLANATION

Description

The description of the enquiry which appears on the Authority Enquiry

Stoplist (Y/N)

Whether this particular enquiry should have leading 'the' 'a' etc automatically removed

Where a.AUTH_TAG_NO

= nnn AND/OR a.AUTH_TAG_NO

The SQL program statement used in the enquiry. The SQL statements formulating the enquiry are added to the program at Runtime and almost any enquiry may be defined. The SQL statement is consistent in its format:

Single Tags

"Where a.auth_tag_no = nnn" (where nnn is the Tag number being queried)

Multiple Tags may be queried by repeating the statement and joining it with an OR clause:

"Where a.auth_tag_no = nn1 OR a.auth_tag_no = nn2"

Please Note: Whenever joining TAGS with an OR statement, place brackets around the statement, after Where to the last tag_no – for example: WHERE (A.Auth_tag_no = 440 OR A.Auth_tag_no = 245)

Authority enquiries may be used to browse the Authority files and subsequently viewing of associated catalogues where applicable.

The Catalogue module has a similar enquiry options facility. Both enquiries use the same base data. The essential difference between the two modules is that this enquiry always shows a list of matching Authority records, which may or may not have associated catalogue records, whereas the

catalogue enquiry always shows a list of matching catalogues. The search term in both cases is a ‘like’ Authority entry (except when the keyword option has been selected).

 Note: The keyword enquiry option is always present in the system and does not need to be defined (these options are defined by their presence in the Marc Keyword Restrictors table).
