sql查詢鎖表

❶ 查看Oracle中是否有鎖表的sql

1、查看是否有鎖表的sql
代碼如下:
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、查看被鎖的表
代碼如下:
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$locked_object b,all_objects c
where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id ;
3、查看那個用戶那個進程造成死鎖，鎖的級別
代碼如下:
select b.owner,b.object_name,l.session_id,l.locked_mode fromv$locked_object l, dba_objects
4、查看連接的進程
代碼如下:
SELECT sid, serial#, username, osuser FROMv$session;
5、查看是哪個session引起的
代碼如下:
select b.username,b.sid,b.serial#,logon_time
from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time;
6、殺掉進程
代碼如下:
alter system kill session 'sid,serial#';

❷ 怎麼查看 sql server 資料庫有沒有鎖表

查看sql server資料庫被鎖表可以用用如下語句：

拓展資料：

SQL Server 是Microsoft 公司推出的關系型資料庫管理系統。具有使用方便可伸縮性好與相關軟體集成程度高等優點，可跨越從運行Microsoft Windows 98 的膝上型電腦到運行Microsoft Windows 2012 的大型多處理器的伺服器等多種平台使用。

Microsoft SQL Server 是一個全面的資料庫平台，使用集成的商業智能 (BI)工具提供了企業級的數據管理。Microsoft SQL Server 資料庫引擎為關系型數據和結構化數據提供了更安全可靠的存儲功能，使您可以構建和管理用於業務的高可用和高性能的數據應用程序。

❸ 如何查看SQL表死鎖

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)
用這個查詢兩次，如果兩次都有某個語句就是了，可以用kill結束它

❹ Oracle 鎖表情況查詢sql

select LOCK_INFO.OWNER || '.' || LOCK_INFO.OBJ_NAME as "已鎖物件名稱", --物件名稱(已經被鎖住)

LOCK_INFO.SUBOBJ_NAME as "已鎖子物件名稱", -- 子物件名稱(已經被鎖住)

SESS_INFO.MACHINE as "機器名稱", -- 機器名稱

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

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

SESS_INFO.SPID as "OS系統的SPID", -- OS系統的SPID

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

LOCK_INFO.ORA_USERNAME as "ORACLE用戶", -- ORACLE系統用戶名稱

LOCK_INFO.OS_USERNAME as "OS用戶", -- 作業系統用戶名稱

LOCK_INFO.PROCESS as "進程編號", -- 進程編號

LOCK_INFO.OBJ_ID as "對象ID", -- 對象ID

LOCK_INFO.OBJ_TYPE as "對象類型", -- 對象類型

SESS_INFO.LOGON_TIME as "登錄時間", -- 登錄時間

SESS_INFO.PROGRAM as "程式名稱", -- 程式名稱

SESS_INFO.STATUS as "會話狀態", -- 會話狀態

SESS_INFO.LOCKWAIT as "等待鎖", -- 等待鎖

SESS_INFO.ACTION as "動作", -- 動作

SESS_INFO.CLIENT_INFO as "客戶資訊" -- 客戶資訊

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 如何查詢鎖表的SQL

用下邊的語句查詢，如果想結束直接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)
