Re: Using a Reference file in a SQL Table

Hi Rob;

Since SQL nicely has "correlation id's" - the same a RPG people will think
of as "qualified" keyword - the there is no need for prefixing
column names in tables.

And it is not very SQL'is the extra qualification.

In your example it would be:

Select item_number
from item_master_has_a_long_name itm
where itm.item_number > 0;

note the itm is the correlation id and the "dot" to qualify.

Curiosity questions about your field reference file...

Are you using the same column names in each of the tables or are you
prefixing them? For example, if your reference file has item_number are
you calling it itm_item_number in one file and ord_item_number in another?
Or are you allowing for more modern code like PREFIX

Are you putting the check constraints in your field reference file, in the
final tables, or just not using anything not in DDS? (check constraint)

Does anyone know how to use a Reference file when creating a SQL Table.
The reference file is not in the current library list. We don't want to
hard code the library.
