This job already has one schedule that runs on the first of the month. However, we need to run the job on a different schedule if the first of the month falls on a Sunday. It appears to me that the SQL Server Agent Job Properties Scheduler GUI is not flexible enough to handle this type of schedule. I am continuing to research this items. Any thoughts or examples (if powerhell is needed) would be appreciated. We are running SQL Server 2019 on Windows Server 2019.

You could schedule a job to run on the first of the month, but immediately exit the job if that day is a Sunday. Add a second sched to that same job that runs on, say, the first Monday of the month, but immediately exit the job unless the previous day was Sunday / it is the second day of the month. And so on, to get the specific schedule you need.

So the job must run on its original schedule and also if 1st of month is Sunday.

So you don’t want to change out the existing schedule or make changes to the job steps?

I would keep it relatively simple and have a 2nd agent job

“RunJob<name>FirstOfMonthWhenSunday” and do a schedule of the 1st of the Month at the needed time.

Then the contents would be in pseudo code

IF DATENAME(weekday,getdate()) = ‘Sunday’

BEGIN

EXEC msdb.dbo.sp_start_job (<jobname>)

END

ELSE

PRINT ‘1st wasn’t a Sunday’

Strongly suggest that you calculate the dates beforehand, insert the dates in a table and have the job check if the date exists in the table.

😎

From now until the 1st of May 2050, there are only 46 dates where the first of the month lands on a Sunday, there is no need to calculate this every day.

USE TEEST;
GO
SET NOCOUNT ON;
GO
DECLARE @START_DATE DATE = '20230101';
DECLARE @DURATION   INT  = 10000;
;WITH T(N) AS (SELECT X.N FROM (VALUES (0),(0),(0),(0),(0),(0),(0),(0),(0),(0)) X(N))
,  NUMS(N) AS (SELECT TOP(@DURATION) ROW_NUMBER() OVER (ORDER BY @@VERSION) AS N 
               FROM T T1,T T2,T T3,T T4,T T5,T T6,T T7,T T8,T T9)
,DATE_TABLE AS
(
    SELECT
        DATEADD(DAY,NM.N,@START_DATE) AS TDATE
    FROM NUMS NM
)
SELECT
    DT.TDATE
   ,DATENAME(WEEKDAY,DT.TDATE)
FROM DATE_TABLE DT
WHERE (DATEDIFF(DAY,0,DT.TDATE) % 7) = 6
AND   DATEPART(DAY,DT.TDATE) = 1;

I don't believe you need a date table for this. It would just be another thing to worry about. I'd use a method similar to what Ant-Green used.

you made it clear that you do not wish the job to run on the first of the month if it it is on a Sunday - but what do you do you EXACTLY wish to do if the first of the month is a Sunday? run it as part of another set of jobs? run it on following Monday?

you were not clear on that side of the requirements other than stating you wish it to run on different schedule.

I do agree with you Jeff that given the sparse requirements posted, a date table might be an overkill. But what will happen if someone decides that the job cannot run on Friday the 13th?

😎

Other factors that can tilt the table, like execution frequency haven't been disclosed, is this a job that runs 100.000.000 times every day or does it only run on the first day of every month? A single data page table lookup might not be such a bad solution after all 😉

My suggestion is that a date table isn't needed for any of that. It's real easy to detect things like Friday the 13th in code and uses fewer resources.

Do you have two different schedules? What are those schedules like? Does it run multiple times per day or does it run once, but at a different time if it's Sunday? It's simple to discontinue the process if today is Sunday, but if you need the process to run at different times, you might need to create two schedules and another job that runs at midnight on the 1st to activate and deactivate the appropriate schedule. There's probably a cleaner way, but it depends on the nature of the different schedules.

Very simple example:

sqlcmd -S <ComputerName>\<InstanceName> -i <MyScript.sql> -o <MyOutput.rpt>

Just use a sqlcmd SQL script with the function below using a windows scheduled task in a batch file:

If datepart(dw,getdate()) = 7

...

Just as a bit of a sidebar... I've been burned in the distant past by the "dw" datepart, especially with inter-country code. The same holds true with the "wk" date part. It only recognizes Sunday for DATEDIFF and DATEDIFF_BIG. Works fine for DATEADD but I've simply gotten out of the habit of using either.

In response to frederico_fonseca

This job already has one schedule that runs on the first of the month. However, we need to run the job on a different schedule if the first of the month falls on a Sunday. The job runs on the first of the starting at 5 A.M. If the first of the month falls on a Sunday, we need the job to start at 6:15 A.M. (We have 7 jobs that need this requirement. One of the jobs has 29 job steps. So, just duplicating the Jobs with a different job name and adding the second schedule may not be wise. If changes need to made they would have to be made in two places or jobs.)

I would create a second schedule that runs at 6:15 on the first and assign it to all seven jobs. The jobs will now have two active schedules.

Create another job that runs before 5am on the first and give that job a step that activates and deactivates the appropriate schedule based on whether it is a Sunday.

Make sure both schedules are clearly named and don’t assign them to any other jobs. Maybe add some kind of alert if either schedule is changed or a new job is assigned to one of them.
