 SQL to Generate Random Numbers?

As part of a database-building project which I'm managing, I want to
enforce quality control standards for data-entry by selecting a
statistically-representative sample of records, which will be evaluated
against original, hardcopy documentation.  I've got a handle on things
like sample size and stratification, but, of course, in order to be a
representative sample, it must also consist of records selected randomly.
Is there any way to do this in SQL? (specifically, we're using SQL*PLUS in
ORACLE 6.0)  Is there, for example, a "random" number generator available
in SQL, which will allow the extraction of random records from the
database?  Any help would be much appreciated--thanks.

I don't know how to build a random number generator on Oracle 6.  But,
since Oracle 7 implements procedures, I was able to write one.
