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.
