Hi Birgitta

I'm a little confused - seems to me that SQL doesn't store anything - it is a language for reporting and manipulating data from systems that store the data in various forms.

Perhaps a small distinction - to me, it is the DB component of any RDBMS that defines how data elements are stored physically. SQL is like a layer that converts that stored item into the several formats.

I don't know what the internal storage of things like Oracle or SQL Server are, that might be interesting to me.

(scaliger no) so the reported length is 4.
AFAIK there is no service or view that considers the "date format".

I'm playing around with these tables relating to some utility software.

I notice that if you have a date in a table that the reported length is 4 -
which while technically accurate is fundamentally useless as a program can
never see it as that length. The output from DSPFFD on the other hand shows
the length as 8 or 10 based on the date format.

Am I missing something? Is there another table or a column in either
SYSCOLUMNS or SYSCOLUMN2 that does accurately represent the size of the
column or do I have to calculate it?
