Re: Why are joins between tables in dif db so slow?

Both times seem a bit long, even if you database has millions of rows. Can you post and explain of your query? That they are in different databases should have minimal effect on your query. Brent On Oct 3, 2008, at 12:14 PM, mos wrote: I have two indexed MyISAM tables, each in a separate da

That seems like a nice trick. I suppose the flag would just be an int and not an enum in this case. 2008/10/3 Mr. Shawn H. Corey <[EMAIL PROTECTED]>: > On Fri, 2008-10-03 at 09:58 -0700, Rob Wultsch wrote: >> On Fri, Oct 3, 2008 at 9:49 AM, Alex K <[EMAIL PROTECTED]> wrote: >> > Hello, >> > >> > I

Hi, Personally I would do #3 as well. Have an exact copy (structurally) of your original table, when the record is deleted then move the account's details to your deleted_users table so it doesn't appear in users but you still have all the details. Not sure if it's possible in MySQL but in

Why are joins between tables in dif db so slow?
