Re: SQL dates and numeric columns

As I have previously recommended create a table using DDL with fields for
Date data type, date in ccyymmdd, numeric cyymmdd, mmddyy, mmddccyy and one
for century number, year number, month number and day number. Then write a
quick and dirty program to accept a range of dates to write.

Make sure you use DDL for high speed indexes. create the indexes when
creating the table.

Now you need a date converted just join to table and get converted to any
other format.

If you do with math SQL cannot optimize.

If you need example of table I can create one for you. Just let me know.

Hi,



Trying to do date operations on a physical file where the date is coded in
3 different numeric fields Y, M and D



1 - I created a view, can I do better than this :

date(trim(char(Y))!!'-'!!trim(char(M))!!'-'!!trim(char(D))) "MyDate"

?


2 – This works in an SQL session but the RPG compiler doesn’t seem to like
the ‘ !’ character. Any ideas ?
