An intersting mix of commentary unfortunately mostly negative .

I bought  a license for the older incarnation as PromptSQL and loved it . It too had the quoted memory implications .

Having loaded and used the new SQLPrompt version much of the slowness has been overcome , I work with it a 512Mb Laptop and a 768Mb desktop and do notice the difference but only just. Add more memory and i suspect it would go away totally.

For those who have condemned SQLPropmt , it maybe they didn't spend sufficient time setting up the options.

In my experience any slowness of response is on the initial load of the db schema as you initially change to a new Db. In my work I have to support upwards of 10 db daily and I see this regularly. Once the schema is there its seamless.

You gather I am a Vast Fan , maybe I just type slowly or I am a lousy typist but as with intellisence in vs2005 I would be without it for productivity reasons. Add SQLprompt to the query designer in VS2005 and what more do you want ??
