在PL/SQL中如何用SQL语句查询数据库中所有表的数据数量？
参考技术A select tablespace_name,sum(bytes)/1024/1024from dba_extents where tablespace_name='数据表空间名' group by tablespace_name;
单位：M本回答被提问者和网友采纳 参考技术B 这个可以先收集数据库表的统计信息然后从数据字典中查询数据库表的数据量相关信息。 参考技术C select all table from database 呵呵 参考一下
SQL SERVER 中如何用脚本管理作业
在SQL SERVER中用脚本管理作业，在绝大部分场景下，脚本都比UI界面管理作业要高效、简洁。打个简单的比方，如果你要查看作业的运行时长，如果用UI界面查看，100个作业，你就得在历史记录里面至少查看一百次甚至更多，还要记录、统计作业各个步骤的执行时间。而用脚本，一个查询就OK了。这篇文章分享一些我在数据库管理过程中积累的一些常用脚本。 如有不足或需要完善的地方，也请多多指教。
1：业务场景：你想了解一下所有作业的Schedule信息，方便你作出调整或分析。例如作业的执行频率；例如你想查询那些作业是一小时执行一次的，那些是间隔几分钟执行一次的，使用下面脚本来查看吧。
DECLARE @ManyTimes TABLE
(
freq_relative_interval INT,
times NVARCHAR(12)
)
INSERT INTO @ManyTimes
SELECT 1 ,N‘第一个‘ UNION ALL
SELECT 2 ,N‘第二个‘ UNION ALL
SELECT 4 ,N‘第三个‘ UNION ALL
SELECT 8 ,N‘第四个‘ UNION ALL
SELECT 16 ,N‘最后一个‘
DECLARE @WeekDays TABLE
(
freq_interval INT,
weekdays NVARCHAR(120)
)
INSERT INTO @WeekDays
SELECT 1 ,N‘星期日 ‘ UNION ALL

INNER JOIN msdb.dbo.sysjobschedules d ON s.schedule_id=d.schedule_id
INNER JOIN msdb.dbo.sysjobs j ON d.job_id = j.job_id
ORDER BY j.name
如下测试案例，非常的清晰明了，一目了然。
2：业务场景：你想查看这个数据库实例有多少作业。
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,l.name AS JOB_OWNER
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,[description] AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
INNER JOIN sys.syslogins l ON l.sid = j.owner_sid
ORDER BY j.name
在这个SQL上可以引申出跟多的SQL，例如查询某段时间内创建的作业等等
3：业务场景： 你想查看、统计哪些作业被禁止了。
--查看实例下被禁用的作业
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,l.name AS JOB_OWNER
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,[description] AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
INNER JOIN sys.syslogins l ON l.sid = j.owner_sid
WHERE j.enabled =0
ORDER BY j.name
4： 业务场景： 你想查看有那些账号在运行那些作业，例如某个同事离职了，但是他的那个NT账号在运行一些作业，你需要修改作业的Owner，否则当系统管理员禁用这个NT账号后，这些作业就会出错。
--查看某个Owner的作业
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,l.name AS JOB_OWNER
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,[description] AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
INNER JOIN sys.syslogins l ON l.sid = j.owner_sid
WHERE l.name=‘Domain\\UserName‘
ORDER BY j.name
5：业务场景：你需要查看作业的具体步骤，例如作业执行的某个存储过程，或者有个同事想了解作业的运行情况，但是他不记得作业的名称，只知道这个作业执行了某个存储过程，那么就可以在下面SQL的基础上进行扩展。
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,s.step_id AS Step_Id
,s.command AS Command
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,[description] AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
INNER JOIN msdb.dbo.sysjobsteps s ON j.job_id = s.job_id
ORDER BY j.name, s.step_id
--查询那个作业执行了某个存储过程（因为有时候，忘记了作业名称,但是知道那个作业调用了某个存储过程，此时开发人员找你帮忙找到对应的作业,就可以通过下面SQL查找）
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,s.step_id AS Step_Id
,s.command AS Command
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,[description] AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
INNER JOIN msdb.dbo.sysjobsteps s ON j.job_id = s.job_id
WHERE s.command LIKE ‘%procedure_name%‘
6：业务场景：数据库迁移时，你想把属于这个数据库的作业也迁移走，但是那些作业是在这些数据库上面运行呢？ 可以通过下面SQL来查找。
---查看属于某个数据库的作业(根据作业脚本执行的数据库判定)
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,[description] AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
WHERE job_id IN( SELECT job_id
FROM msdb.dbo.sysjobsteps
WHERE database_name = ‘YourSQLDba‘ )
ORDER BY j.name
7：业务场景：需要查看那些作业类型为“操作系统（CmdExec)"的作业。
--查看作业类型为“操作系统（CmdExec)"的作业
SELECT j.job_id AS JOB_ID
,j.name AS JOB_NAME
,CASE WHEN [enabled] =1 THEN ‘Enabled‘
ELSE ‘Disabled‘ END AS JOB_ENABLED
,j.category_id AS JOB_CATEGORY_ID
,c.name AS JOB_CATEGORY_NAME
,description AS JOB_DESCRIPTION
,date_created AS DATE_CREATED
,date_modified AS DATE_MODIFIED
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.syscategories c ON j.category_id = c.category_id
WHERE EXISTS
(SELECT 1 FROM msdb.dbo.sysjobsteps s WHERE
j.job_id = s.job_id AND s.subsystem=‘CmdExec‘)
8： 业务场景： 需要查看今天或某个时间段内出错的作业。
--查询那些作业在今天出错（如果要查询历史出错作业，去掉查询时间条件即可）
SELECT j.name AS JOB_NAME
,j.description AS JOB_Description
,j.date_created AS Date_Created
,j.date_modified AS Date_Modified
FROM msdb.dbo.sysjobs j
WHERE enabled = 1
AND EXISTS (
SELECT 1
FROM Msdb.dbo.sysjobhistory h
WHERE run_status = 0
AND j.job_id = h.job_id
AND run_date = CAST(CONVERT(VARCHAR(8), GETDATE(), 112) AS INT) )
---查看某个或所有作业的出错的历史记录信息
SELECT j.name AS job_name
, h.step_id AS step_id
, h.step_name AS job_step_name
, h.sql_severity AS sql_severity
, h.[message] AS error_message
, h.run_date AS run_date
, h.run_time AS run_time
, h.run_duration AS run_duration
FROM msdb.dbo.sysjobhistory h
LEFT JOIN msdb.dbo.sysjobs j ON h.job_id =j.job_id
WHERE run_status=0
--AND j.job_name =‘‘
ORDER BY j.name, h.run_date, h.run_time, h.step_id
9： 业务场景： 查看作业的执行时间信息。
--查询作业的运行时间，检查作业是否正常运行或存在问题。
SELECT j.name AS Job_Name ,
h.step_id AS Step_Id ,
h.step_name AS Step_Name ,
h.message AS Message ,
h.run_date AS Run_Date ,

msdb.dbo.agent_datetime(h.run_date, h.run_time)
AS ‘RunDateTime‘ ,
CAST(run_duration / 10000 AS VARCHAR(2)) + N‘小时‘
+ CAST(( run_duration - run_duration / 10000 * 10000 ) / 100 AS VARCHAR(2)) + N‘分钟‘
+ SUBSTRING(CAST(run_duration AS VARCHAR(10)),
LEN(CAST(run_duration AS VARCHAR(10))) - 1, 2) + N‘秒‘
AS run_duration
FROM msdb.dbo.sysjobhistory h
LEFT JOIN msdb.dbo.sysjobs j ON h.job_id = j.job_id
ORDER BY Job_Name, h.Step_Id
SELECT j.name AS Job_Name ,

WHERE Run_Date = CAST(CONVERT(VARCHAR(8), GETDATE(), 112) AS INT) --今天执行的作业
AND h.run_status = 1 --执行成功
ORDER BY h.run_duration DESC
10： 业务场景： 查询作业运行时间超过某个阀值的所有作业。例如作业执行时间超过一分钟的作业
查询今天执行时间大于一分钟的作业
SELECT j.name AS Job_Name ,
h.step_id AS Step_Id ,
h.step_name AS Step_Name ,

+ SUBSTRING(CAST(run_duration AS VARCHAR(10)),
LEN(CAST(run_duration AS VARCHAR(10))) - 1, 2) + N‘秒‘
AS run_duration
FROM msdb.dbo.sysjobhistory h
LEFT JOIN msdb.dbo.sysjobs j ON h.job_id = j.job_id
WHERE Run_Date = CAST(CONVERT(VARCHAR(8), GETDATE(), 112) AS INT) --今天执行的作业
AND h.run_status = 1 --执行成功
AND h.run_duration > 100 --大于一分钟的作业
ORDER BY Job_Name, h.Step_Id
11：业务场景，查看正在执行的作业。
SELECT job.job_id,
job.name ,
sa.run_requested_date,
sa.start_execution_date
FROM msdb.dbo.sysjobs_view job
INNER JOIN msdb.dbo.sysjobactivity sa ON job.job_id = sa.job_id
-- get only the current session
INNER JOIN msdb.dbo.syssessions s ON s.session_id = sa.session_id
INNER JOIN ( SELECT MAX(agent_start_date) AS max_agent_start_date
FROM msdb.dbo.syssessions
) session_max ON s.agent_start_date = session_max.max_agent_start_date
WHERE sa.run_requested_date IS NOT NULL
AND sa.stop_execution_date IS NULL;
12：业务场景，查看某个作业的详细信息。
EXEC msdb.dbo.sp_help_job @Job_name = ‘YourSQLDba_LogBackups‘
还有一些零零散散的关于作业的脚本没有整理，以后有时间再做补充。
