2.查询原字段内容
select contact
from pbx_agents
where contact ~ 'effective_caller_id_name=' limit 2
"{sip_append_audio_sdp=a=fmtp:18 annexb=no,call_timeout=60,effective_caller_id_name=051066824513,effective_caller_id_number=051066824513,cti_account=9,cti_agent_id=1102441276,cti_account_sid=5be394c3f8754bd89b9618937c687068,absolute_codec_string=\'OPUS,G729 (...)"
"{sip_append_audio_sdp=a=fmtp:18 annexb=no,call_timeout=60,effective_caller_id_name=051066824824,effective_caller_id_number=051066824824,cti_account=9,cti_agent_id=1103211003,cti_account_sid=4f3fae0e71b74bdaa3824e6ec7771815,absolute_codec_string=\'OPUS,G729 (...)"
3.查询语句验证替换
select regexp_replace(contact, '(effective_caller_id_name=\d+,)+?','','g')
from pbx_agents
where contact ~ 'effective_caller_id_name='
"{sip_append_audio_sdp=a=fmtp:18 annexb=no,call_timeout=60,effective_caller_id_number=051066824513,cti_account=9,cti_agent_id=1102441276,cti_account_sid=5be394c3f8754bd89b9618937c687068,absolute_codec_string=\'OPUS,G729\'}sofia/gateway/agentProxy/1102441276"
