Oracle查询可以有多种方法,下面为您介绍的是如何Oracle查询被锁的表及Oracle查询连接的进程的方法,希望对您能够有所帮助. 一.查看被锁的表 select p.spid,a.serial#, c.object_name,b.session_id,b.oracle_username,b.os_user_name from v$process p,v$session a, v$locked_object b,all_objects c where p.addr=a.paddr and a

1.Oracle查询数据库中所有表的记录数,但是有可能不准建议用第二种方式进行查询 select t.table_name,t.num_rows from user_tables t 2.创建oracle函数,通过函数中查询词表记录数显示当前记录数 create or replace function count_rows(table_name in varchar2, owner in varchar2 default null) return number authid current_us

--查询已锁的表 select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName ,* from sys.dm_tran_locks where resource_type='OBJECT' --解锁表(@spid) declare @spid int Set @spid = 62 --锁表进程 declare @sql varchar(1000) set @sql='kill '+cast(

-- 查询字段在什么表 select * from all_tab_cols t where t.column_name='ABC'; -- 查询字段在什么表并且 判断是否是主键 select * from all_tab_cols t left join ( select a.table_name, a.constraint_name, a.column_name, b.constraint_type -- 字段约束类型(P:主键) from user_cons_columns a inner

查看被锁的表 select p.spid,a.serial#, c.object_name,b.session_id,b.oracle_username,b.os_user_name from v$process p,v$session a, v$locked_object b,all_objects c where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id ; 查看那个用户那个进程照成死锁,锁的级别se

Oracle数据库,查询某表中包含在子表中的数据,子表中数据按特定条件来源于该父表,SQL命令如 ) a_table父表,b_table子表,a和b表都有commandId列,a表的commandId主键关联b表中的外键commandId,要求a表中commandId包含在b表commandId中,且b表的type黑白名单类型为1的数据 (即查出b表存在的关联的a表的数据) 也可以用:(仅限于一对一的情况,一对多会出现主表重复的情况) ; 如(一对多出现的问题): 或者是 select * fr

1.数据库锁表查询语句: SELECT SESS.SID, SESS.SERIAL#, LO.ORACLE_USERNAME, LO.OS_USER_NAME, AO.OBJECT_NAME 被锁对象名, LO.LOCKED_MODE 锁模式, sess.LOGON_TIME 登录数据库时间, 'ALTER SYSTEM KILL SESSION ''' || SESS.SID || ','||SESS.SERIAL#||'''' FREESQL FROM V$LOCKED_OBJECT LO,

在oracle 上面查看别锁定的表,以及解锁表的sql: select t3.object_name,t3.owner,t2.machine,t2.sid,t2.serial# from v$locked_object t1,v$session t2,dba_objects t3 where t1.session_id = t2.sid and t1.object_id = t3.object_id; alter system kill session'101,1507'; # sid , se
