Creating EVENTS in SQL Server - sql

I want to execute a query at a specific time. In MySQL we use events for that, example is as follows:
CREATE EVENT myevent
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 HOUR
DO
UPDATE myschema.mytable SET mycol = mycol + 1;
Please let me know how to do the same in SQL Server. Thanks.
PS : Sorry if its a repeated question. I tried searching for some time but didn't get it in SQL Server

You can use Sql server agent for this task and you can schedule there. Its easy way.
Another one is "waitfor time" check this link http://msdn.microsoft.com/en-IN/library/ms187331.aspx
(and you need to create a trigger with while loop logic and there wait for time is useful)
Another one create a bat file and schedule that in windows scheduler (if you are using sql sever express edition)

How to calculate the next run date for a SQL Server agent job

I am developing a custom system for scheduling task & I am following Microsoft SQL Server Agent approach to schedule task.
I have replicated sysschedules table for capturing users scheduling occurrences and timings.
Now I need to know how SQL Server get the Next_run_date and time from this table.
I have found a solution on the internet which are using sysjobhistory table to get the next run date, but in my case, I have an only sysschedules table. So, what is the formula to calculate the next_run_date and time for any job?
Note: I am looking for entire code, concept/algorithm will work for me.

How to change a column value based on date (every year)

I am working on a leave management system, and this is my first web application. I have a LocalDB sql server in visual studio 2010 and I need some columns to be updated every year.
For example, I have SickLeave column (int), I need this column to be updated with the value (15) in a specific date (every year), the date will be different from one employee to another based on his joining date.
I have searched a lot, there is something called scheduled event in mySQL that can do something similar, but it doesn't work for sql server.
So anyone has an idea how to do it? Your help will be appreciated.
Thanks in advance.
You can use a SQL Agent Job.
SQL Agent: https://msdn.microsoft.com/en-us/library/ms189237.aspx
Create a Job: https://msdn.microsoft.com/en-us/library/ms190268.aspx
We use these for all sorts of scheduled tasks.
In your case you could create Job that runs Daily, the job can execute a StoredProc (or simple Update statement).
UPDATE Employee SET SickLeave = 15 WHERE DAY(JoinedDate) = DAY(GETDATE()) AND MONTH(JoinedDate) = MONTH(GETDATE())

How to automatically update database SQL Server?

I need a field (column) of my database to update automatically. For example, the field NUMBER for each record incrementing every minute. How can I do it? I am using SQL Server.
You're probably looking for something called SQL Server Agent jobs
here is a good starting point reference:
http://technet.microsoft.com/en-us/library/ms181153(v=sql.105).aspx
This allows you to run some sql code on a schedule of your choosing.
P.S.
If you have access to sql server management studio, the GUI is much nicer.
You can set up a SQL Agent job to run an update statement once a minute:
UPDATE tablename
SET NUMBER = NUMBER + 1
Job Agent is only for full SQL Server. Then best choise. If you using SQL express then can't. You can solve with update
UPDATE TABLE-NAME SET
VALUE = VALUE + 1

create ms sql server job schedule from datetime database

I'm using microsoft SQL server management studio 2005
I'm trying to run a job at a specific time and that time is stored in a database.
I can't insert the schedule manually because it is up to the user to decide what date and time the job(s) has to be done. php collects the time and date and sends it to a database.
I thought about runing a job every min and in my execution I have an if statement that only activates when the datetime stored in the database is one minute greater or lower than the current datetime. but doing it like this would be inaccurate and very inefficient. would it be possible to create a schedule directly from a query or job?
You can create and modify both jobs and schedules programmatically using SMO or TSQL. That means you can use an external application, a stored procedure or a trigger to create or update a job schedule based on the table data. SMO is probably the best way to go if you want to build an application to manage jobs, but on the other hand it's .NET only.

How to run a stored procedure in sql server every hour?

I have a table on which I want to perform some operations every hour. For this I created a Stored Procedure but don't know how to call it every hour. I know there are some kind of scheduled jobs, but how to use them.
Is there some kind of service also that keeps on running continuously, every second, where I can place my piece of code to be executed ?
In SSMS navigate to SQL Server Agent-->Jobs
Right click on the Job Folder and select new job
on the dialog that pops up, give the job a name
click on steps, then on new, you will see a dialog like the following, pick correct DB and type your proc name
after that click on schedule, pick new and you will see something like the image below, fill all the stuff you need and click ok, click ok on the job and you should be set
1) Use the SQL Server Agent (open MS Management Studio)
2) New Job
3) Add Step
4) Choose Transact SQL
5) EXEC MyStroredProc
6) Choose database
7) Add schedule
8) Occurs every hour
Add notification to know that process is doing well (or bad).
In the properties of SQL Server Agent check that all Auto restart options are switch ON
Set up a SQL Server agent job to execute the stored procedure at 1 hour intervals
