#1: SQL HELP PLEASE!! Cursor only returns part of the data

Posted on 2007-07-26 02:30:11 by Simon Barnett

Hi,



I would much appreciate some help with a work project that is due very soon.



I have used a cursor to return the required result from a db table in order
for me to use in an ASP/VBScript webpage. This is the first time I have
used a cursor and am having problems.



The problem is that instead of returning all the data as a single query
result that can be loaded into an ADO recordset and looped thru in my ASP
page, it is returned (when run in Query Analyser) as 3 individual query
results in 3 different frames (the same as if you ran 3 individual queries
in the QA window at the same time) - one for each of the rows that make up
the cursor. So when I loop through the recordset on my webpage it only
contains one of the query results and not all of the data I require.



Below is my representation of a chunk of the db table, the tsql as run in
MSSQL Query Analyser and a representation of the results returned.



I hope I have made this email clear enough, let me know if otherwise. Many
thanks in advance for your help.

Simon Barnett

Apologies - I only just noticed that this is a mySQL group not MSSQL.

Although I've always been led to believe that open source developers spit on
sn MS clones, if you can help with my problem I would be very grateful.

Many thanks
Simon
