Faster return of large recordset
Hi,

I remember reading somewhere that there is a faster way to retrieve a large recordset to display it in a table, could anyone point me in the right direction.

Thanks,

Sanjay

Your right, I'm using Dreamweaver to extract 1000 records but it takes a long time to display,

The query is:
PHP Code:
 SELECT *
FROM tick_tbl
WHERE monthentry = MMColParam 


I just wanted to know the most effeicient method for displaying these results (1000 - 1500) records with approx. 25 fields.

Thanks,

Sanjay

You can specify the column names individually rather than use *. Generally this is a bit faster.

Look at indexing the monthentry column if it isn't.

I'm retriving all the fields, should I still specify each column?

I'm looking at trying to optimise the DB,

Is there any reason why I should not index say 10 columns rather than one?

Also, should I increase the MaxBufferSize or MaxScanRows (not sure what they do) in the ODBC setup dialog?

Thanks,

Sanjay

Even if you need all the columns, specifying the column names saves the db server some work. I've read it's faster, but I don't work in heavily loaded environments often so I can't say for sure.

Indices put extra load on the server when inserting or updating, I try to index only what's necessary.

If it's your server you can try tweaking the ODBC properties.

Thanks Doug,

We are on a dedicated server, I just wanted some help in what options I could set to maximise performance for the DB, I've not seen anything around - any help would be welcome.

Regards,

Sanjay
