Detect if table exists from within MySQL?

[Ryan Stille]

I am converting some code from MSSQL to MySQL.  In one place I need to
have a conditional query depending on if a table exists or not.  There
are different versions of this application and the table only exists in
some of them.  Here is how it was done in MSSQL:

IF OBJECT_ID('cfgbiz') IS NOT NULL
  SELECT notifyto FROM cfgbiz
ELSE
  SELECT '' as notifyto

Is there something similar in MySQL? I am running version 4.1.x.

Thanks,
