Re: Use of non-standard LIMIT keyword in JDBC tableExists code

Granted the 1=0 thing is ugly and assumes constant-folding support or reads way too much data. Submitted JIRA SPARK-9078 (thanks for pointers) and expounded on possible solutions a little bit more there. Cheers, and thanks, Bob -- View this message in context: http://apache-spark-developers-
