Bryan Pendleton commented on DERBY-5235:
----------------------------------------

Can't do "SELECT DISTINCT" if the distinct list contains a CLOB, I think.

> The original Cloudscape limit for the length of VARCHAR values was java.lang.Integer.MAX_VALUE.
That is the limit in Cloudscape 5.1. Nothing in Derby should break if we restore the original
limit. The current limit is an artificial bound introduced to make Derby agree with DB2. 32672
is the upper bound on the length of a DB2 VARCHAR: http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/admin/r0001029.htm
