org.apache.derby.iapi.types.StringDataValue.concatenate()
The SQL concatenation '||' operator. @param leftOperand String on the left hand side of '||' @param rightOperand String on the right hand side of '||' @param result The result of a previous call to this method,null if not called yet. @return A ConcatableDataValue containing the result of the '||' @exception StandardException Thrown on error

            StringDataValue leftValue = (StringDataValue) leftOp.getValue();
            StringDataValue rightValue = (StringDataValue) rightOp.getValue();
