SQL Trivia – What are Niladic functions in SQL Server?
Niladic functions are functions that do not accept any parameters, are specified without parentheses, and return only one result.
Following is the list of Niladic functions:
| Niladic function (SQL-92) | Value returned |
|---|---|
| CURRENT_TIMESTAMP | Current date and time. |
| CURRENT_USER | Name of user performing an insert. |
| SESSION_USER | Name of user performing an insert. |
| SYSTEM_USER | Name of user performing an insert. |
| USER | Name of user performing an insert. |
Execution of below query with these functions gives following results:
SELECT CURRENT_TIMESTAMP AS 'CURRENT TIMESTAMP' ,CURRENT_USER AS 'CURRENT USER' ,SESSION_USER AS 'SESSION USER' ,SYSTEM_USER AS 'SYSTEM USER' ,USER AS 'USER'

Microsoft PSS – SQL 2016 Series: It just runs faster | Feb-March updates
Microsoft PSS Engineers have built a series on “It Just Runs Faster”!
“In the Sep 2014 the SQL Server CSS and Development teams performed a deep dive focused on scalability and performance when running on current and new hardware configurations. The SQL Server Development team tasked several individuals with scalability improvements and real world testing patterns. You can take advantage of this effort packaged in SQL Server 2016. – https://www.microsoft.com/en-us/server-cloud/products/sql-server-2016/”
SQL 2016 will run faster in many ways, without changing code.
The series kickoff is here:

The first article in this series came out the end of February:

Custom Query to check Frequency, Interval and Time of multiple Job’s in SQL Server
In my [previous post] I discussed about the system SPs that we can use to get details of a SQL Job, like its Name, ID, Description, Schedule, etc. But what if you need to check these details of various SQL Jobs?
Here in this post we will see how we check the Job Schedule of various SQL Jobs, like:
1. Enable/Disable
2. Frequency (Once, Daily, Weekly, Monthly, etc.)
3. Interval (Specific time, Seconds, Minutes, Hours, etc.)
4. Start Date and Time
5. Description
… by using some system views, like:
– sysJobs
– sysJobsShedules
– sysSchedules
select
'Job ID' = j.job_id
,'Job Name' = j.name
,'Job Enabled' = case j.enabled
when 1 then 'Yes'
else 'No'
end
,'Frequency' = case s.freq_type
when 1 then 'One time only'
when 4 then 'Daily'
when 8 then 'Weekly'
when 16 then 'Monthly'
when 32 then 'Monthly, relative to freq_interval'
when 64 then 'Runs when the SQL Server Agent service starts'
when 128 then 'Runs when the computer is idle'
end
,'Interval' = case s.freq_subday_type
when 1 then 'At specified time'
when 2 then CAST(freq_subday_interval AS VARCHAR(3)) + ' Seconds'
when 4 then CAST(freq_subday_interval AS VARCHAR(3)) + ' Minutes'
when 8 then CAST(freq_subday_interval AS VARCHAR(3)) + ' Hours'
end
,'Start_Date' = substring(convert(varchar(15),active_start_date),1,4)
+ '/' + substring(convert(varchar(15),active_start_date),5,2) + '/'
+ substring(convert(varchar(15),active_start_date),7,2)
+ ' ' +
case len(active_start_time)
when 1 then cast('00:00:0' + right(active_start_time,2) as char(8))
when 2 then cast('00:00:' + right(active_start_time,2) as char(8))
when 3 then cast('00:0'
+ left(right(active_start_time,3),1)
+':' + right(active_start_time,2) as char (8))
when 4 then cast('00:'
+ left(right(active_start_time,4),2)
+':' + right(active_start_time,2) as char (8))
when 5 then cast('0'
+ left(right(active_start_time,5),1)
+':' + Left(right(active_start_time,4),2)
+':' + right(active_start_time,2) as char (8))
when 6 then cast(Left(right(active_start_time,6),2)
+':' + Left(right(active_start_time,4),2)
+':' + right(active_start_time,2) as char (8))
end
,'Schedule Enabled' = case s.enabled
when 1 then 'Yes'
else 'No'
end
,'Schedule Desc' = s.name
from msdb.dbo.sysjobs j
inner join msdb.dbo.sysjobschedules js
on j.job_id = js.job_id
inner join msdb.dbo.sysschedules s
on s.schedule_id = js.schedule_id
order by j.name
GO

I’ve created the above query by collating references form forums and MSDN BoL, you can tweak and modify this query as well as per your requirements.
Using system SPs to get details of SQL Jobs, Steps, Commands, Schedule, Last run details, etc
Sometimes it get difficult or time-taking to get each and every SQL Job details, its schedule and other information. Also checking all these information in SSMS is time taking specially when your machine is running a client, and the server is located in some remote place. On the other side if you get some handy system Queries you can fire them in SSMS and get the desired results immediately, without browsing too much on heavy GUI tools.
Here are some of the System Stored Procedure queries that can be used to check the SQL Job details, like:
1. Job Details:
– Job ID/Name/Description
– Category
– Date Created/Modified
– Last/Next run Date/Time
– Current execution status
2.Job Steps
– Step ID/Names
– SQL Commands in each step
– On Success/Fail action
– Last run Duration/Retries/Date/Time
3. Job Schedule:
– Schedule ID/Name/Description
– Enable/Disable Status
– Job Frequency/Interval
– Job Start Date/Time
– Next run Date/Time
–> sp_help_job: system SP gives you all these information in 4 different result sets as shown in the image below. You can pass Job-Name or Job-ID as parameter to the system SP.
exec msdb.dbo.sp_help_job @job_name = 'Acquire_Source_Data' -- OR -- exec msdb.dbo.sp_help_job @job_id = 'ad8252d8-35d8-4c1f-b603-db0dfebd5e27'

–> sp_help_jobstep & sp_help_jobschedule: these 2 SPs also gives similar information provided by above SP (sp_help-job), but with single result-set. So you can execute them independently and use them in your logic.
exec msdb.dbo.sp_help_jobstep @job_id = 'ad8252d8-35d8-4c1f-b603-db0dfebd5e27' exec msdb.dbo.sp_help_jobschedule @job_id = 'ad8252d8-35d8-4c1f-b603-db0dfebd5e27' --

View Dependencies of a Table from SSMS and T-SQL script used internally by SSMS
Here we will see how to check the Table level dependencies, means what all Database Objects a Table is related to, like Views, Stored Procedures (SPs), Functions (UDFs), Triggers, etc.
Go to Object Explorer, and expand the Databases -> Tables and Right click on the Table that you want to see dependencies.
Select View Dependencies, you will get a popup listing all objects that depends upon this table.
–>1. The below image shows the Objects that depend on Customer table:

–>2. Once you select the second radio-button it shows the Objects on which Customer table depends:

–> And here is a very lengthy (~900 lines) T-SQL Code that I generated from SSMS & SQL Profiler to check the same Dependencies of a Table in SQL Server 2014. You can also create a Stored Procedure and apply the Table & Schema as parameters.
You can just replace the Table & Schema in the first 2 lines and execute the code to check table dependencies:
DECLARE @Table_name NVARCHAR(1000) = N'Customer' -- replace your table here
DECLARE @Schema_name NVARCHAR(1000) = N'Sales' -- replace the schema here
