Then I loop through the array and add the parameters. So i need to change all the query strings in the app (there are lots of them )

My other concern is that the company uses Small Business Server, which I understand also uses SSE, and I'm terrified I'm going to mess up the server when I install another instance of SSE....

..adding another instance of Sql Server would make the entire PC somewhat slower. Adding another server would be costly too.

Is at a large database? How many tables are we talking?

There are about 20 tables, some of the tables have about 4000 records (stock_qty)

In a month they added about 4000 rows to the Sales Order Detail table, each of which has a correspronding entry in a Stock History table

 

The Access db is about 4MB

I'd get someone who knows a bit more about servers to assist!

I was leaning towards them getting another PC on the network and put and instance of SSE (with different instance name to the default) on that... Perhaps a performance loss but less risk
