Selecting the first row out of many sql joins
- by IcedDante
Alright, so I'm putting together a path to select a revision of a particular novel:
SELECT Catalog.WbsId, Catalog.Revision, NovelRevision.Revision
FROM Catalog, BookInCatalog
INNER JOIN NovelMaster
INNER JOIN HasNovelRevision
INNER JOIN NovelRevision
ON HasNovelRevision.right = NovelRevision.obid
ON HasNovelRevision.Left=NovelMaster.obid
ON NovelMaster.obid = BookInCatalog.Right
WHERE Catalog.obid = BookInCatalog.Left;
This returns all revisions that are in the Novel Master for each Novel Master that is in the catalog.
The problem is, I only want the FIRST revision of each novel master in the catalog. How do I go about doing that? Oh, and btw: my flavor of sql is hobbled, as many others are, in that it does not support the LIMIT Function.
