WAITFOR DELAY: How can I continue to delay and excute until process is complete?

Question

Hello my friends:
Is it possible to run a select statement an wait, then run again until the table has no data?
The following is an example code:
BEGIN
IF (SELECT COUNT(*) FROM MySchema.MyTable) > 1
BEGIN
WAITFOR DELAY '00:00:5';
SELECT COUNT(*) FROM MySchema.MyTable;
END
END
I want to repeat the code above with the delay until the table count is zero.
Is this possible?
Thanks!

I have several options:
Because this is a SSIS Task, I can use a loop and get the data as available with a pause
I can add the wait in TSQL in a stored procedure
Maybe I can put a pause in the program itself.
I'm not sure I understand what you mean about option 3 since this is an SSIS package. These options are easily doable. I could be inclined to implement the pause in an SSIS script task containing the code below, with the package controlling the loop.
System.Threading.Thread.Sleep(10000);

Hey Dan, with option 3: I was meaning to put a pause in the calling method which execute the stored procedure to the Dataset.
Moving on with your recommendation, there is one area which confuses me.
I found the follow article:
http://www.bidn.com/blogs/mikedavis/ssis/158/make-an-ssis-package-delay-or-wait-for-data
I need the task to execute (go to another task) if the count is not zero,  then pause.
Now do the whole thing over after a few seconds until the Count is zero.
Currently if the Count is not zero, the task execute and finishes but that's it, nothing else happens. I guess I am looking to repeat the entire process until the count is zero.
Step 1: If Count != 0 run task B
Step 2: Pause for 15 seconds
Step 3: Re-evaluate the count again if it is still not equals zero, run task B again.
Pause and reevaluate the count, if it is zero exit.
