I'm trying to do an sql_pvquery() and have PostgreSQL return the default value using COALESCE (if the other parts of the query return NULL) rather than placing the $null check on the return in the Kamailio script. I seem to be coming up on a parser issue, perhaps too many nested parentheses:
sql_pvquery("kamailio",
"SELECT COALESCE((SELECT value FROM usr_preferences WHERE
attribute='callee_rtp_transport'
AND (uuid='$sht(rtpengine=>$ci::$T_branch_idx::callee_ip)'
OR username='$rU') LIMIT 1), 'RTP/AVP')",
"$sht(rtpengine=>$ci::$T_branch_idx::callee_rtp_transport)");
<core> [cfg.y:3428]: yyerror_at(): parse error in config file
/etc/kamailio/kamailio.cfg, line 1444, column 14: syntax error
Is this query "too complex" for the parser, or is there something I've missed
above?
Thanks. -A
