Re: An easy (I think) SQL question

there is little talk about taking a date input (such as current date) and

IBM provides a LAST_DAY function but does not provide a FIRST_DAY
function. Yes, everyone knows that the first day of the month is 1. But
whip up a 'simple' sql function which returns the date of the first day of
the month from 3 months ago.



​Using the CURRENT_DATE - (DAY(CURRENT_DATE) - 1) days - 3 months
works

But I usually use
last_day(current_date) + 1 day - 4 months

It'd be nice if IBM added a FIRST_DAY
