Re: PF Compiled Files with Dictionaries vs. SQL-Created Tables

You can continue to use a "dictionary" file even with SQL created tables...

Simply use the
create table MYNEWTBL as
(SELECT fld1, fld2 from DATADICT)
with no data
syntax.

optionally adding "copy options" such as
INCLUDING IDENTITY COLUMN ATTRIBUTES
INCLUDING COLUMN DEFAULTS
ect...

There's been articles done about this, google
SQL "Field reference files"

Hi All,

For years (prior to my arrival), the programs written around here were all based on physical file definitions.  However, these definitions were never really consistent - a field of one type may not be the same type and length in another file.  We then began moving to creating tables with SQL statements, keeping in mind the importance of creating fields that were the same type and length regardless of the table in which they were used.  However, this was cumbersome because we always had to keep a running list of field definitions along with their sizes and types.

We're now looking to move back to physical file definitions with a twist - all definitions will be contained in a single dictionary file that lists all of the fields, their types and their lengths.  Even though we will have to do a lot of data table conversion, I am hoping this will allow us to centralize the definitions and not have to worry that a field in one table may not be the same in another.

Has anyone had any experience similar to our current conundrum and if so, did you solve it using a similar method?  If not, what worked best for you?

Thanks!
