Yes, an index would be needed.

Subject: Re: Best method using SQL to combine date fields (day, month,
year)


Create a UDF (download Alan's(?) iDate UDF)...
Create a view that uses the UDF...

Now the problem, if you're intending to use this date as a selection
criteria, an index will not be used even if one exists over the three
columns. (Unless you're at v6r1, then you can build an index with the
calculated value)

Do you need the index for performance?

Ok, building some dynamic SQL statements.

Got to a file that has date separated into year, month and day
fields. Ugh.

So, wondering the best/easiest way to combine these so I can
use them in an
SQL statement? Hopefully some magical SQL command that I can
use inline?

Thanks!
