DDL is the language syntax used in SQL to define database tables (Data Definition Language). While the resulting file objects are nearly identical, the DDL file will be a bit more efficient with I/O buffering and data validation.
There are numerous redbooks, redpieces, and whitepapers that compare the operational efficiencies of DDL vs DDS objects, as well as a few dozen threads on this in the archives.

Well, if you convert your DB2 files from DDS to DDL, then you could
never load the bad data into the file in the first place. DDS validates
data when reading from DASD, where DDL validates data when writing to
DASD.
I am definitely NOT a fan of FIXNBR....

Subject: Handling decimal data errors at the field level
Hi,
Has anyone had any experience handling decimal data errors at the field
level? I know you can trap for the decimal data error that happens when
a record is read that contains a decimal data error in one of the field
values, and I know you can set the FIXNBR parameter on the RPG compile
to automatically fix numeric values that are bad. But I want to know
which specific field(s) in the record were bad. It's OK that the
compiler will fix them for me, but I want to know which field(s) in the
record were fixed.
Any ideas?
Best Regards,
Thomas Garvey
