Message-ID: <370FF843.4F119EE@mindspring.com> Date: Sat, 10 Apr 1999 21:17:55 -0400 From: "James E. Harrell" <james_harrell@mindspring.com> Subject: un-enforced "unique" indicesHaving a problem with unique indices... The index will enforce UNIQUE
when you attempt to insert *new* data, but when you update current data
in an indexed field, it allows non-unique data to be created... any
suggestions?
Basically, I'd like the database to kick back the update as invalid to
avoid doing the unique check manually. That's part of why unique indices
exist, no?
Table looks something like:
category_name char(30)
categoryID int
groupID int
The create index clause looks like this:
CREATE UNIQUE INDEX idx_cid on categories (categoryID)
CREATE UNIQUE INDEX idx_cid_gid on categories (category_name, groupID)
Shouldn't this allow duplicate categories ONLY if the groupID is
different? In other words, several different groups can have categories
by the same name. But a single group can not have 2 categories by the
same name.

Hi,
Is it possible to know the name of a page of redirection ?
And in this case they are nothing in http-referer :-(
The page of redirection is in phtml v.2
Thank you very much.
Patrick
