Question

We send mailouts every evening using SQL. For this in particular we’d like to send a reminder every 3 days, but I have absolutely no idea how to do this, or if it’s even possible?

Here’s my code:

SELECT *
FROM   table
WHERE  status = 'pending'
       AND ( date_created = sysdate - 3
              OR date_created = sysdate - 6
              OR date_created = sysdate - 9 )  

Something to that effect, but a nicer way of coding it and also a more effective one that won’t require me to go all the way into the hundreds! ^_^

Thanks

Try

SELECT *
FROM table
WHERE status = 'pending'
AND MOD(sysdate-date_created, 3) = 0
