If you quote backslash, you corrupt data for databases that follow the SQL standard and don’t use backslash. <snarky MySQL comment elided> This is really more a problem with using a “quote” function instead of proper parameterized queries. I don’t believe it’s possible to accommodate both escaping methods with the same function. If parameterized queries aren’t possible to do in FS (or too much work), there should probably be some switch that controls backslash handling. -Michael From: freeswitch-dev-bounces@lists.freeswitch.org [mailto:freeswitch-dev-bounces@lists.freeswitch.org] On Behalf Of Seven Du Sent: Wednesday, February 08, 2012 6:55 AM To: freeswitch-dev Subject: [Freeswitch-dev] backslash in call-id Hi, I have a sip client which generates call-id with backslashes which causing error: ERR: [insert into sip_registrations ............. values ('<c)X/Iz\' I looked into http://sofia-sip.sourceforge.net/refdocs/sip/group__sip__call__id.html looks like backslash '\' is valid in call-id so is it ok to to let switch_mprintf %q also quote backslash ? should I report a jira?
