regex error

Hello,
I want to log all rysylog I configure and everything is fine.
I create a new template that is:
template(name="stdSQLformat" type="string" option.sql="on" string="insert into SystemEvents (Message, Message2, Facility, FromHost, Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag) values ('%msg%','%msg:R,ERE,0,DFLT,1:([0-9]+\.){3}[0-9]+[:]?([0-9]+)?"--end%', %syslogfacility%, '%HOSTNAME%', %syslogpriority%, '%timereported:::date-mysql%', '%timegenerated:::date-mysql%', %iut%, '%syslogtag%')")
but when I run rsyslog I get:
error during parsing file /etc/rsyslog.d/mysql.conf, on or before line 8: invalid character '"' in object definit
I know that the problem is with
%msg:R,ERE,0,DFLT,1:([0-9]+\.){3}[0-9]+[:]?([0-9]+)?"--end%
but I don't understand what I have to do !
thanks.
