[SVN commits to the Asterisk project]

Author: seanbright
Date: Tue Jun  8 10:28:49 2010
New Revision: 269006

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=269006
Log:
Reduce startup time for cdr_tds with large CDR tables.

Since we are just checking for table existence, add a WHERE clause that will
return no rows but will raise an error if the table doesn't exist.

(closes issue #17380)
