What is the limit of rows in a table for SQL Server 2005, when SQL query starts getting slower? Is there any way to find out the limit?
I understand it will depend upon the data length of a row. This will also depend on how many more data in other tables and the hardware available.
I think you are asking the wrong question.
If you have the ‘right’ indexes to cover your query workload, the number of rows won’t make much difference until you reach 10’s or 100’s millions of rows.
Make sure your server has enough RAM.
