【xp_sqlagent_enum_jobs】取得SQL Ser_sqlserver

xp_sqlagent_enum_jobs是微软未公开的存储过程，用于取得作业的相关信息，在自己进行调度处理多作业时，用它来判断作业的执行情况再合适不过了。
create table #help_job(
    job_id UNIQUEIDENTIFIER NOT NULL,
    last_run_date INT NOT NULL,
    last_run_time INT NOT NULL,
    next_run_date INT NOT NULL,

    next_run_time INT NOT NULL,
    next_run_schedule_id INT NOT NULL,
    requested_to_run INT NOT NULL, — BOOL
    request_source INT NOT NULL,
    request_source_id sysname NULL,
    running INT NOT NULL, — BOOL
    current_step INT NOT NULL,
    current_retry_attempt INT NOT NULL,
    job_state INT NOT NULL
)–判断作业是否正在运行
    while @job_run_flag = 1
    begin
        –删除临时表信息
        delete #help_job
        –添加信息
        INSERT INTO #help_job
        EXECUTE master.dbo.xp_sqlagent_enum_jobs 1, ‘sa’
       
        if exists (select * from  msdb.dbo.sysjobs a,#help_job b where a.job_id=b.job_id and a.name=’job1′ and b.job_state = 4 and b.request_source_id is null)
        begin
            set @job_run_flag = 0
        end
        else
        begin
            –延时一分钟
            waitfor delay ‘000:01:00’
        end

    end

    –执行其他作业
    exec msdb.dbo.sp_start_job @job_name = ‘job1’

    –更新服务器状态
    –update SYS_Server set UpdateFlag = 0 where PID = @PID
    set @job_run_flag = 1
b.request_source_id is null一定要加上，否则多次启动同一个作业的时候有可能报错。

我的存储过程，大家可以借鉴一下

CREATE PROCEDURE proc_pmis_main
AS

–更新准备
exec proc_pmis_updateready

–临时表
create table #help_job(
    job_id UNIQUEIDENTIFIER NOT NULL,
    last_run_date INT NOT NULL,
    last_run_time INT NOT NULL,
    next_run_date INT NOT NULL,
    next_run_time INT NOT NULL,
    next_run_schedule_id INT NOT NULL,
    requested_to_run INT NOT NULL, — BOOL
    request_source INT NOT NULL,
    request_source_id sysname NULL,
    running INT NOT NULL, — BOOL
    current_step INT NOT NULL,
    current_retry_attempt INT NOT NULL,
    job_state INT NOT NULL
)

–作业是否正在运行
 –1：正在运行;0:未运行
declare @job_run_flag int
set @job_run_flag = 1
declare @PID int
–循环提取数据
declare area_cursor cursor for
select PID from SYS_Server where UpdateFlag = 1 and UseFlag = 1 order by PID

open area_cursor
fetch next from area_cursor into @PID
while @@fetch_status =0
begin
    –判断作业是否正在运行
    while @job_run_flag = 1
    begin
        –删除临时表信息
        delete #help_job
        –添加信息
        INSERT INTO #help_job
        EXECUTE master.dbo.xp_sqlagent_enum_jobs 1, ‘sa’
       
        if exists (select * from  msdb.dbo.sysjobs a,#help_job b where a.job_id=b.job_id and a.name=’job_pmis_synch’ and b.job_state = 4 and b.request_source_id is null)
        begin
            set @job_run_flag = 0
        end
        else
        begin
            –延时一分钟
            waitfor delay ‘000:01:00’
        end

    end

    –执行同步作业
    exec msdb.dbo.sp_start_job @job_name = ‘job_pmis_synch’

    –更新服务器状态
    –update SYS_Server set UpdateFlag = 0 where PID = @PID
    set @job_run_flag = 1
    –print (@PID)

    fetch next from area_cursor into @PID
end
close area_cursor
deallocate area_cursor

drop table #help_job
GO
