SqlServer 查看死锁的进程以及处理

在进程中的头阻塞显示了1，说明有死锁。

查看当前死锁

SELECT
    request_session_id spid,
    OBJECT_NAME(
        resource_associated_entity_id
    ) tableName
FROM
    sys.dm_tran_locks
WHERE
    resource_type = 'OBJECT'

查看死锁信息

exec master.dbo.sp_who_lock;--查看当前死锁进程
exec master.dbo.p_killspid ytsafety;--杀掉引起死锁的进程

查看进程信息

SELECT * FROM sys.dm_exec_connections;
SELECT * FROM sys.dm_exec_sessions;
SELECT
    spid,
    blocked,
    DB_NAME(sp.dbid) AS DBName,
    program_name,
    waitresource,
    lastwaittype,
    sp.loginame,
    sp.hostname,
    a.[Text] AS [TextData],
    SUBSTRING (
        A. TEXT,
        sp.stmt_start / 2,
        (
            CASE WHEN sp.stmt_end = - 1 THEN DATALENGTH (A. TEXT) ELSE sp.stmt_end END - sp.stmt_start
        ) / 2
    ) AS [current_cmd] FROM sys.sysprocesses AS sp OUTER APPLY sys.dm_exec_sql_text (sp.sql_handle) AS A WHERE spid > 50 ORDER BY blocked DESC,
    DB_NAME(sp.dbid) ASC,
    a.[text];

杀掉死锁进程

kill spid
