sql查询锁表

❶ 查看Oracle中是否有锁表的sql

1、查看是否有锁表的sql
代码如下:
select 'blocker('||lb.sid||':'||sb.username||')-sql:'|| qb.sql_text blockers,
'waiter ('||lw.sid||':'||sw.username||')-sql:'|| qw.sql_text waiters
from v$lock lb,
v$lock lw,
v$session sb,
v$session sw,
v$sql qb,
v$sql qw
where lb.sid=sb.sid
and lw.sid=sw.sid
and sb.prev_sql_addr=qb.address
and sw.sql_address=qw.address
and lb.id1=lw.id1
and sw.lockwait is not null
and sb.lockwait is null
and lb.block=1 ;
2、查看被锁的表
代码如下:
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$locked_object b,all_objects c
where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id ;
3、查看那个用户那个进程造成死锁，锁的级别
代码如下:
select b.owner,b.object_name,l.session_id,l.locked_mode fromv$locked_object l, dba_objects
4、查看连接的进程
代码如下:
SELECT sid, serial#, username, osuser FROMv$session;
5、查看是哪个session引起的
代码如下:
select b.username,b.sid,b.serial#,logon_time
from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time;
6、杀掉进程
代码如下:
alter system kill session 'sid,serial#';

❷ 怎么查看 sql server 数据库有没有锁表

查看sql server数据库被锁表可以用用如下语句：

拓展资料：

SQL Server 是Microsoft 公司推出的关系型数据库管理系统。具有使用方便可伸缩性好与相关软件集成程度高等优点，可跨越从运行Microsoft Windows 98 的膝上型电脑到运行Microsoft Windows 2012 的大型多处理器的服务器等多种平台使用。

Microsoft SQL Server 是一个全面的数据库平台，使用集成的商业智能 (BI)工具提供了企业级的数据管理。Microsoft SQL Server 数据库引擎为关系型数据和结构化数据提供了更安全可靠的存储功能，使您可以构建和管理用于业务的高可用和高性能的数据应用程序。

❸ 如何查看SQL表死锁

SELECT SPID=p.spid,
DBName = convert(CHAR(20),d.name),
ProgramName = program_name,
LoginName = convert(CHAR(20),l.name),
HostName = convert(CHAR(20),hostname),
Status = p.status,
BlockedBy = p.blocked,
LoginTime = login_time,
QUERY = CAST(t.TEXT AS VARCHAR(MAX))
FROM MASTER.dbo.sysprocesses p
INNER JOIN MASTER.dbo.sysdatabases d
ON p.dbid = d.dbid
INNER JOIN MASTER.dbo.syslogins l
ON p.sid = l.sid
CROSS APPLY sys.dm_exec_sql_text(sql_handle) t
WHERE p.blocked = 0
AND EXISTS (SELECT 1
FROM MASTER.dbo.sysprocesses p1
WHERE p1.blocked = p.spid)
SELECT SPID=p.spid,
DBName = convert(CHAR(20),d.name),
ProgramName = program_name,
LoginName = convert(CHAR(20),l.name),
HostName = convert(CHAR(20),hostname),
Status = p.status,
BlockedBy = p.blocked,
LoginTime = login_time,
QUERY = CAST(t.TEXT AS VARCHAR(MAX))
FROM MASTER.dbo.sysprocesses p
INNER JOIN MASTER.dbo.sysdatabases d
ON p.dbid = d.dbid
INNER JOIN MASTER.dbo.syslogins l
ON p.sid = l.sid
CROSS APPLY sys.dm_exec_sql_text(sql_handle) t
WHERE p.blocked = 0
AND EXISTS (SELECT 1
FROM MASTER.dbo.sysprocesses p1
WHERE p1.blocked = p.spid)
用这个查询两次，如果两次都有某个语句就是了，可以用kill结束它

❹ Oracle 锁表情况查询sql

select LOCK_INFO.OWNER || '.' || LOCK_INFO.OBJ_NAME as "已锁物件名称", --物件名称(已经被锁住)

LOCK_INFO.SUBOBJ_NAME as "已锁子物件名称", -- 子物件名称(已经被锁住)

SESS_INFO.MACHINE as "机器名称", -- 机器名称

LOCK_INFO.SESSION_ID as "会话ID", -- 会话SESSION_ID

SESS_INFO.SERIAL# as "会话SERIAL#", -- 会话SERIAL#

SESS_INFO.SPID as "OS系统的SPID", -- OS系统的SPID

(SELECT INSTANCE_NAME FROM V$INSTANCE) "实例名SID", --实例名SID

LOCK_INFO.ORA_USERNAME as "ORACLE用户", -- ORACLE系统用户名称

LOCK_INFO.OS_USERNAME as "OS用户", -- 作业系统用户名称

LOCK_INFO.PROCESS as "进程编号", -- 进程编号

LOCK_INFO.OBJ_ID as "对象ID", -- 对象ID

LOCK_INFO.OBJ_TYPE as "对象类型", -- 对象类型

SESS_INFO.LOGON_TIME as "登录时间", -- 登录时间

SESS_INFO.PROGRAM as "程式名称", -- 程式名称

SESS_INFO.STATUS as "会话状态", -- 会话状态

SESS_INFO.LOCKWAIT as "等待锁", -- 等待锁

SESS_INFO.ACTION as "动作", -- 动作

SESS_INFO.CLIENT_INFO as "客户资讯" -- 客户资讯

from (select obj.OWNER as OWNER,

obj.OBJECT_NAME as OBJ_NAME,

obj.SUBOBJECT_NAME as SUBOBJ_NAME,

obj.OBJECT_ID as OBJ_ID,

obj.OBJECT_TYPE as OBJ_TYPE,

lock_obj.SESSION_ID as SESSION_ID,

lock_obj.ORACLE_USERNAME as ORA_USERNAME,

lock_obj.OS_USER_NAME as OS_USERNAME,

lock_obj.PROCESS as PROCESS

from (select *

from all_objects

where object_id in (select object_id from v$locked_object)) obj,

v$locked_object lock_obj

where obj.object_id = lock_obj.object_id) LOCK_INFO,

(select SID,

SERIAL#,

LOCKWAIT,

STATUS,

(select spid from v$process where addr = a.paddr) spid,

PROGRAM,

ACTION,

CLIENT_INFO,

LOGON_TIME,

MACHINE

from v$session a) SESS_INFO

where LOCK_INFO.SESSION_ID = SESS_INFO.SID

order by LOCK_INFO.SESSION_ID;

❺ 如何查询锁表的SQL

用下边的语句查询，如果想结束直接kill
SELECT SPID=p.spid,
DBName = convert(CHAR(20),d.name),
ProgramName = program_name,
LoginName = convert(CHAR(20),l.name),
HostName = convert(CHAR(20),hostname),
Status = p.status,
BlockedBy = p.blocked,
LoginTime = login_time,
QUERY = CAST(t.TEXT AS VARCHAR(MAX))
FROM MASTER.dbo.sysprocesses p
INNER JOIN MASTER.dbo.sysdatabases d
ON p.dbid = d.dbid
INNER JOIN MASTER.dbo.syslogins l
ON p.sid = l.sid
CROSS APPLY sys.dm_exec_sql_text(sql_handle) t
WHERE p.blocked = 0
AND EXISTS (SELECT 1
FROM MASTER.dbo.sysprocesses p1
WHERE p1.blocked = p.spid)
