If you ever want to find out which SQL Server Agent jobs that are currently running on your server without using Management Studio, just run the code below.
SELECT ja.job_id, j.name AS job_name, ja.start_execution_date, ISNULL(last_executed_step_id,0)+1 AS current_executed_step_id, Js.step_name FROM msdb.dbo.sysjobactivity ja LEFT JOIN msdb.dbo.sysjobhistory jh ON ja.job_history_id = jh.instance_id JOIN msdb.dbo.sysjobs j ON ja.job_id = j.job_id JOIN msdb.dbo.sysjobsteps js ON ja.job_id = js.job_id AND ISNULL(ja.last_executed_step_id,0)+1 = js.step_id WHERE ja.session_id = ( SELECT TOP 1 session_id FROM msdb.dbo.syssessions ORDER BY agent_start_date DESC ) AND start_execution_date is not null AND stop_execution_date is null order by 2 desc
To secure AWS properly, you need to do some initial steps within IAM (Identity Access Management). These steps are used to make it harder for hackers to take control of your AWS Cloud System.
You need to make sure that when you go into IAM, you go through all the steps and make sure that your IAM screen has all the green ticks like the following image.
These are just some basic things you need to do before you start to implement any design you think about doing within AWS.
Once you have set up individual user accounts, make sure you stop using the root account and start to use an IAM User. This is because if somebody manages to gain access to your root account, then they will be able to destroy your entire cloud environment. Make sure that your root account password with multifactor authentication is kept secure with limited access to others.
Has it finished? is a question you will ask yourself many times when you are running something within SQL Server. If you are backing up a database, restoring a database or you just want to find out how long a task on your server will take to complete, then just run the code below to return information about each request that is executing within SQL Server.
CONVERT(NUMERIC(6,2),dmr.percent_complete)AS [Percent Complete],
CONVERT(VARCHAR(20),DATEADD(ms,dmr.estimated_completion_time,GetDate()),20) AS [ETA Completion Time],
CONVERT(NUMERIC(10,2),dmr.total_elapsed_time/1000.0/60.0) AS [Elapsed Min],
CONVERT(NUMERIC(10,2),dmr.estimated_completion_time/1000.0/60.0) AS [ETA Min],
CONVERT(NUMERIC(10,2),dmr.estimated_completion_time/1000.0/60.0/60.0) AS [ETA Hours]
CASE WHEN dmr.statement_end_offset = -1 THEN 1000
ELSE (dmr.statement_end_offset-dmr.statement_start_offset)/2 END)
FROM sys.dm_exec_requests dmr
where CONVERT(NUMERIC(6,2),dmr.percent_complete) > 0

I have been in a position where I wanted to know the status of my databases at regular intervals and I would want this information in a script. Well here is a script that I have used in the past that once placed in a job, I could monitor if the database changes its state then of this information, it could send me an email.
It is handy to track to see if your database goes into a funny state during the day.
select name as DBNAME,getdate() as RUNDATE, STATUS, STATUS2,
CASE WHEN (STATUS & 1) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [AUTOCLOSE],
CASE WHEN (STATUS & 4) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [SELECT_INTO_BULKCOPY],
CASE WHEN (STATUS & 8) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [TRUNC_LOG_ON_CHKPT],
CASE WHEN (STATUS & 16) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [TORN_PAGE_DETECTION],
CASE WHEN (STATUS & 32) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [LOADING],
CASE WHEN (STATUS & 64) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [PRE_RECOVERY],
CASE WHEN (STATUS & 128) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [RECOVERING],
CASE WHEN (STATUS & 256) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [NOT_RECOVERED],
CASE WHEN (STATUS & 512) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [OFFLINE],
CASE WHEN (STATUS & 1024) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [READ_ONLY],
CASE WHEN (STATUS & 2048) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [DBO_USE_ONLY],
CASE WHEN (STATUS & 4096) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [SINGLE_USER],
CASE WHEN (STATUS & 32768) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [EMERGENCY_MODE],
CASE WHEN (STATUS & 4194304) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [AUTOSHRINK],
CASE WHEN (STATUS &1073741824) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [CLEANLY_SHUTDOWN],
CASE WHEN (STATUS2 & 16384) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [ANSI_null_default], –This one
CASE WHEN (STATUS2 & 65536) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [concat_null_yields_null],
CASE WHEN (STATUS2 & 131072) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [recursive_triggers], — This one
CASE WHEN (STATUS2 & 1048576) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [default_to_local_cursor], –This one
CASE WHEN (STATUS2 & 8388608) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [quoted_identifier],

CASE WHEN (STATUS2 & 67108864) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [ANSI_nulls],
CASE WHEN (STATUS2 & 268435456) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [ANSI_warnings],
CASE WHEN (STATUS2 & 536870912) = 0 THEN ‘FALSE’ ELSE ‘TRUE’ END AS [full_text_enabled]

I thought I would write this article for people who have no experience in SQL Server or know what a database is.
A database is a method of storing information where that information can be accessed to answer or to solve questions. There are many types of databases that you can use from many different companies like
• IBM DB2
With every database, you have to ability to insert, delete, update and search information that is stored within them.
Here are some examples that you would use a database
• Storing your music collection information
• Storing a sports team activity
• Storing pupils attendance at a school.
A vast amount of things that you use today will have some built-in database system for them to store data, i.e. your mobile phone.
Microsoft have a database software called SQL Server which they have been developing since 1989 and the current version of SQL Server is called SQL Server 2017.
There are many different versions of SQL Server 2017 that are designed for different people and different solutions. The main versions that people use are
• SQL Server Enterprise Edition
• SQL Server Standard Edition
• SQL Server Business Intelligence Edition
• SQL Server Developer Edition
• SQL Server Express
SQL Server Enterprise, SQL Server Standard and SQL Server Business Intelligence Edition all cost money to use in a production/business environment
SQL Server Developer Edition is free and can only be used on test systems and cannot be used in production/business environment
SQL Server Express can be used in a test environment and production environment for free.
SQL Server Enterprise and SQL Server Developer have all the features enabled and SQL Server Express has limited features enabled.
Within SQL Server, you can create a database and a database is a collection of tables that store the data. You access this data by using a special database language called T-SQL or you can use a frontend application as well.

If you want to monitor the performance of your queries within SQL Server 2017, you can with a feature called Query Store. Query Store monitors changes to your queries to see if performance deteriorates or improves when the query plan changes.
When you create a new database, is disabled by default; you need to enable this feature.
To enable Query Store, do the following steps
1. In Object Explorer, right-click a database, and then click Properties.
2. In the Database Properties dialogue box, select the Query Store page.
3. In the Operation Mode (Requested) box, select On.
You would use Query Store when you want to
• Find queries that have become slow over time and fix them by forcing the queries to use a different query plan.
• Find out how many times a query was run in a set period.
• Find out how many times the query plan was changed.
• Analysis why your query plan changes.
The best way to learn about
is to play around with it so just enable it and refresh the database, so it looks like this
Then just double click on each item in the query store to see what they do. It is better to enable Query Store on a database that has many transactions so you will be able to see results appear fast. I would suggest using a development server to test this feature as turning on this feature can have a minor effect on performance on your server.

SQL Server has a lot of useful information that you need to administrate or develop solutions. Here is a great SQL Script to find out information about your SQL Server Instance and operating system.
