To whoever may know,
I have a couple of questions about Oracle v7 and I hope that some of you will
take the time to answer them. Please do and THANX when you do!
- Does Oracle7 support fieldtypes for "free tekst of undefined length", like
- Same question for "pictures" (bitmaps, tiffs, gifs or whatever)?
- Is it possible to randomly select a number of records from a sub-set of
records? Suppose I had a DB with 1000 employees (with fields like: gender,
age, name) and I wanted to randomly select 10 males older than 25 (and
there were 400 males older than 25).
- Is it possible to change the "structure" of a DB-table containing data,
like inserting new fields or making a field longer?
