Re: Question on buffer lengths vs SQL reported lengths

The physical storage method for a date is to store it as a 4 byte count of the number of days since ... (Can't recall).

BUT you can really not easily ever see it like that. The operating system always surfaces it in its edited 8 or 10 character form.

Even the compilers can't see the "raw" 4 bytes - but nevertheless that is how it is physically stored/

Anyone have any ideas why if I do a "select * from qsys2.syscolumns where table_schema='yourschema' and table_name='tablename'" and you look at the STORAGE or LENGTH columns for a DATE field it says "4"

But when you do a DSPFFD against the same file you will see the field length is 10.

I've noticed a discprency on TIME fields as well. Where the qsys2.syscolumns STORAGE and LENGTH columns say "3", but DSPFFD shows 8
