Conditional execution in Teradata Stored Procedure based on date value

I'm creating a stored procedure that checks the quality of the data loaded into our data warehouse on a daily basis.  Most of the table checks in the stored procedure run on a daily basis.  However, some of the table checks only need to run once a month as they are tables that are only loaded once a month.

I was curious if it was possible within the stored procedure to set some kind of condition that would permit that particular block of code to only execute when the date value equalled the first of the month?

Thank you!

Why not check the system date's day of month to see if it is equal to a 1?
Of course, the issue would be, what if the system is down on the first through 3rd of the month?  So, what I would suggest is a "cheat" that I use for various similar tasks that I have created.  Create a simle little controlling table that has the task name, a last run date, a RunInterval, and a NextRun date or .  Then you populate that table with the appropriate information and, in you process, you check to see if today is >= NextRunDate.  If it is, then you execute that step in the process and, upon successful completion, update the Last Run Date and set the NextRunDate (of course, on a failure, you don't touch the control table row ;-).  That way, you can see the date of the last successful run and then next scheduled Run Date.  (If you want to get fancy, you can have a column for Days, one for Months, and one for Years to increment the NextRunDate. ;-)
