In the case of an ASP application, using ADO and a client side cursor you
could just fetch the records, and then check the recorcount of the
recordset. That combines your first two steps into one. I don't understand
your third step.

You can probably wrap it all into 1 stored proc assuming you're using
SQL server. The first two parts can be done quite easily as BV
suggests, what is the third bit? Is it to do with grouping?

How about some sample results? And/Or the webpage?

Thanks BV

Basically what I was planning to do is to open a table 3 times to
retrieve the following:
1) Content list, which will be displayed on to the client screen
2) Count the number of records retrieved
3) Retrieve properties region (eg. Postcodes 43554, 5543…) (using the
DISTINCT function when querying the table to eliminate duplicate values)

The table that I’m querying has to be INNER JOINT with 3 different
tables.

My question was:
Is it better to:
a) query the tables three times or;
b) run the query one time and insert the results into a local temporary
table that will contain a maximum of 200 records, then access the
temporary table as many times as needed?

After some more research I think the answer to that question should be
(b).
If anybody know a better way or think that I’m wrong, please replay...

PS: In your previous email you have mention about client side cursor.
I have posted another message title: "CursorLocation: Client Side Cursor
(How does it work?)" if you would not mind to share a bit more
knowledge, I would really appreciates that...

So you want to get a bunch of columns, present them, get a count, and then
get a list of distinct values from the total data set? If I am understanding
you correctly, I'd use ADO, and get the data in a recordset. You can then
present it and count as I mentioned before to answer 1 & 2. The third option
can be answered by using the recordset and a quick loop to get your distinct
values. I think this would be better then hitting the database a second time
for the distinct values. You can use the recordset.sort property to quickly
sort and fetch the distinct values.
