发帖数: 1275 | 1 is there any difference between these two datatypes in oracle?
ibm websphere doesn't support long in CMP and suggested us to
convert to CLOB.. while weblogic says long support is part of
ejb 2.0 and that they support it.
so what's the difference? thanks | r*********t
发帖数: 4 | 2 Long is a legacy datatype of Oracle and being replaced by CLOB and BLOB. Long
can store up to 2G data and CLOB can store 4G. You can't use WHERE, GROUP BY,
DISTINCT and some other SQL clause for Long datatype. IMHO It's reasonable
that WAS doesn't provide backward compatibility to Long. But I am sure about
he ejb2.0 standard thingy, you sure the 'long' in it is the same thing of Long
in Oracle?
