Home -> Community -> Mailing Lists -> Oracle-L -> RE: [***SPAM***] - Cobol redefine in SQL - Found word(s) to be removed remove list error e-mail in the Text body.
I went thru a conversion like this many moons ago but was to DB2 and not Oracle but in the end was the same.
We looked at each and decided what needed to be defined as a seperate table ( ie the key and redefined portion became a table) and others where we had the key and a large binary field that contained the redefined data. The basic rule was if the data in the redefined could be joined to other data to make the application more functional and give us long term benefit for being able to access the columns via SQL then we broke it out. If the redefined portion was mainly used for internal processing and would not be joined to and would only be accessed via the COBOL programs we left them as is.
Now, that was the easy part. Getting and defining and setting up each table and getting agreement on what went where wasnt as simple. In the end it worked out and worked out pretty well.

Hi all,
We'll do a conversion from IMS to Oracle (817). The conversion team wants to move data on Oracle then processed it.
Off course, in the file format, the cobol redefine command is used on a filler field (20 times). There is also a redefine command in a redefine command.
For the younger ones, it means a zone (50 caracters) that can be defined in many ways depending on a key : 2 fields of 25 char or 5 fields of 10 char or ....
The programmers can always use substring to death to work this out but I was wandering if there was a more elegant and a less error prone solution, maybe using a record type or a function ...
