Can I improve my SQL response times?

I am executing a query that gets some data from a remote server.

It is a simple select query say

select * from opendatasource(----).[Database].[dbo].[Table1]

Now Table1 (has 4 columns) contains 15 hundred-thousand records and is growing in size.

On my server where I get the result set of the query it takes around 6 seconds to get the data. It looks slow to me.

The Table1 has 开发者_如何学Ca primary key field of datatype char(28) and no other index of any kind is defined.

This seems to be the problem.

What might be a possible workaround to make the database do work faster?

Help is appreciated

Thanks

You are pulling whole table. I don't think you can make it faster.

Unless:

• you filter the number of pulled rows (where condition)
• add index covering you where condition
• limit the number of returned field (select field1, field2 vs select *)
• get faster connection between the client (wherever you run the script) and server
