Hi, Yuri, 

I tried Sapphire and get a 'Undefiend' error when connect to my IRIS. the URL I used is : "jdbc:IRIS://LOCALHOST:9091/USER". I am not sure it's okay, because from container system, I can ping LOCALHOST, but I don't think this is the docker Host server, my MAC os, and I can't ping MAC OS's any ip address from docker. Any suggestion? thank you

Than you all for your replies. I heard the %STARTSWITH has better performance but I never know it is in the online document. However, I am a little confused: instead of recommending users to use something with which they are not familiar, why not make 'LIKE' faster?

I was told that before but I never know it written in document. Thanks.
