这篇文章主要介绍了Oracle中获取会话信息的两个函数分享,本文分别讲解了USERENV和两个函数sys_context,并对可以获取哪些信息作了介绍,需要的朋友可以参考下
1、 USERENV(OPTION) 返回当前的会话信息. OPTION='ISDBA'若当前是DBA角色,则为TRUE,否则FALSE. OPTION='LANGUAGE'返回数据库的字符集. OPTION='SESSIONID'为当前会话标识符. OPTION='ENTRYID'返回可审计的会话标识符. OPTION='LANG'返回会话语言名称的ISO简记. OPTION='INSTANCE'返回当前的实例. OPTION='terminal'返回当前计算机名 SELECT USERENV('LANGUAGE') FROM DUAL; 2、sys_context
复制代码代码如下: select SYS_CONTEXT('USERENV','TERMINAL') terminal, SYS_CONTEXT('USERENV','LANGUAGE') language, SYS_CONTEXT('USERENV','SESSIONID') sessionid, SYS_CONTEXT('USERENV','INSTANCE') instance, SYS_CONTEXT('USERENV','ENTRYID') entryid, SYS_CONTEXT('USERENV','ISDBA') isdba, SYS_CONTEXT('USERENV','NLS_TERRITORY') nls_territory, SYS_CONTEXT('USERENV','NLS_CURRENCY') nls_currency, SYS_CONTEXT('USERENV','NLS_CALENDAR') nls_calendar, SYS_CONTEXT('USERENV','NLS_DATE_FORMAT') nls_date_format, SYS_CONTEXT('USERENV','NLS_DATE_LANGUAGE') nls_date_language, SYS_CONTEXT('USERENV','NLS_SORT') nls_sort, SYS_CONTEXT('USERENV','CURRENT_USER') current_user, SYS_CONTEXT('USERENV','CURRENT_USERID') current_userid, SYS_CONTEXT('USERENV','SESSION_USER') session_user, SYS_CONTEXT('USERENV','SESSION_USERID') session_userid, SYS_CONTEXT('USERENV','PROXY_USER') proxy_user, SYS_CONTEXT('USERENV','PROXY_USERID') proxy_userid, SYS_CONTEXT('USERENV','DB_DOMAIN') db_domain, SYS_CONTEXT('USERENV','DB_NAME') db_name, SYS_CONTEXT('USERENV','HOST') host, SYS_CONTEXT('USERENV','OS_USER') os_user, SYS_CONTEXT('USERENV','EXTERNAL_NAME') external_name, SYS_CONTEXT('USERENV','IP_ADDRESS') ip_address, SYS_CONTEXT('USERENV','NETWORK_PROTOCOL') network_protocol, SYS_CONTEXT('USERENV','BG_JOB_ID') bg_job_id, SYS_CONTEXT('USERENV','FG_JOB_ID') fg_job_id, SYS_CONTEXT('USERENV','AUTHENTICATION_TYPE') authentication_type, SYS_CONTEXT('USERENV','AUTHENTICATION_DATA') authentication_data from dual 3.与系统视图v$session组合使用可以获得更多信息(客户端所使用的应用程序等) 复制代码代码如下: select * from v$session se, (select SYS_CONTEXT('USERENV', 'TERMINAL') terminal, SYS_CONTEXT('USERENV', 'LANGUAGE') language, SYS_CONTEXT('USERENV', 'SESSIONID') sessionid, SYS_CONTEXT('USERENV', 'INSTANCE') instance, SYS_CONTEXT('USERENV', 'ENTRYID') entryid, SYS_CONTEXT('USERENV', 'ISDBA') isdba, SYS_CONTEXT('USERENV', 'NLS_TERRITORY') nls_territory, SYS_CONTEXT('USERENV', 'NLS_CURRENCY') nls_currency, SYS_CONTEXT('USERENV', 'NLS_CALENDAR') nls_calendar, &网站seo优化nbsp; SYS_CONTEXT('USERENV', 'NLS_DATE_FORMAT') nls_date_format, SYS_CONTEXT('USERENV', 'NLS_DATE_LANGUAGE') nls_date_language, SYS_CONTEXT('USERENV', 'NLS_SORT') nls_sort, SYS_CONTEXT('USERENV', 'CURRENT_USER') current_user, SYS_CONTEXT('USERENV', 'CURRENT_USERID') current_userid, SYS_CONTEXT('USERENV', 'SESSION_USER') session_user, SYS_CONTEXT('USERENV', 'SESSION_USERID') session_userid, SYS_CONTEXT('USERENV', 'PROXY_USER') proxy_user, SYS_CONTEXT('USERENV', 'PROXY_USERID') proxy_userid, SYS_CONTEXT('USERENV', 'DB_DOMAIN') db_domain, SYS_CONTEXT('USERENV', 'DB_NAME') db_name, SYS_CONTEXT('USERENV', 'HOST') host, SYS_CONTEXT('USERENV', 'OS_USER') os_user, SYS_CONTEXT('USERENV', 'EXTERNAL_NAME') external_name, SYS_CONTEXT('USERENV', 'IP_ADDRESS') ip_address, &nbseo网站关键词优化sp; 网站建设制作SYS_CONTEXT('USERENV', 'NETWORK_PROTOCOL') network_protocol, SYS_CONTEXT('USERENV', 'BG_JOB_ID') bg_job_id, SYS_CONTEXT('USERENV', 'FG_JOB_ID') fg_job_id, SYS_CONTEXT('USERENV', 'AUTHENTICATION_TYPE') authentication_type, SYS_CONTEXT('USERENV', 'AUTHENTICATION_DATA') authentication_data from dual) base where se.AUDSID = base.sessionid;声明: 本文由我的SEOUC技术文章主页发布于:2023-05-22 ,文章Oracle中获取会话信息的两个函数分享建站知识主要讲述函数,两个,Oracle中获取会话信息的两个函数分享建网站建设源码以及服务器配置搭建相关技术文章。转载请保留链接: https://www.seouc.com/article/web_4364.html
