Re: Converting a numeric date value to a DATE in SQL

Alan,
Unfortunately, iDate is not an option for this customer (need to get
permission to install *any* 3rd party software -including- utilities)
I have tried to use SELECT DATE(field) from my file (where field is
20140905), but SQL did not like that and it returned ++++++++.
Is there an easy way to do this?

Using SQL, how do I convert a numeric value of a database field in ISO

I think we all agree that the "right" way to do dates is with date
fields. However, if all you need is to check for equality, probably
the fastest thing to do is to convert your input to numeric ISO and do
a direct comparison with that.

And in your case, even if you had to check for earlier-than,
later-than, or between, you could still use the numeric ISO dates
as-is (this would not be the case for MDY, USA, or EUR numeric-field
dates).

That said, it is probably still worth having iDate. :)
