org.apache.derby.impl.sql.compile.Predicate.binaryRelOpColRefsToString()
Get a string version of the column references for this predicate IF it's a binary relational operator. We only print out the names of the operands if they are column references; otherwise we just print a dummy value. This is for debugging purposes only--it's a convenient way to see what columns the predicate is referencing, especially when tracing through code and printing assert failure.

      {
        pred = (Predicate)storeRestrictionList.getOptPredicate(i);
        if (pred.isInListProbePredicate())
        {
          SanityManager.THROWASSERT("Found IN-list probing " +
            "(" + pred.binaryRelOpColRefsToString() +
            ") while generating HASH join, which should " +
            "not happen.");
        }
