Date Range lookup between tables in asp 2.0
am 18.09.2006 15:36:02 von NickCR04Hi all,
I am (using ASP.net 2.0 in Visual Web developer 2005 Express Edit) trying to
set up an asp front end to a music DB which has 2 main tables:
1) MUSIC - containing music release information (eg label, artist, name,
date reviewed)
2) ISSUES - containing 3 columns - 1) a list of issue numbers and 2) issue
start date and 3) Issue end date columns
I am (a very novice programmer) having difficulty with presenting search
data in a gridview after a user enters the "date reviewed" details in a text
box and hits a button to perform the search.
user enters date and i am trying to get it to lookup the list of dates in
the second table and return the issue number
i create the textbox and button and then create a gridview connecting back
to the db and am getting stuck from here.
I have tried "ADD WHERE" with various SQL Queries/criteria and thought it
could be done in a "RangeValidator" but have had no joy as the upper and
lower ranges are dependent on what is entered in the textbox and must be
looked up from a separate table. can thios be done in RangeValidator?
one string i tried (which returns everything not just the week in Q) is as
follows:
select NEWMUSIC.MusicID, NEWMUSIC.MusicReleaseDate, NEWMUSIC.MusicTitle,
NEWMUSIC.MusicArtist, NEWMUSIC.MusicLabel, NEWMUSIC.MusicReviewedDate,
ISSUEDATES.Issue#
from NEWMUSIC INNER JOIN ISSUEDATES ON NEWMUSIC.MusicReleaseDate Between
ISSUEDATES.ISSUE_START_DATE and ISSUEDATES.ISSUE_END_DATE
I am really struggling here so would appreciate any assistance!
thanks in advance
Nick
