xuchaoguo1983 opened a new issue #1857: pagination is not working well after 3.1.0
URL: https://github.com/apache/incubator-shardingsphere/issues/1857
 
 
   I have a table with no sharding configuration, if I try to ask a page request with certain offset (not zero), it will always return the first page.
   
   I took a look at class DQLMergeEngine, and found that some weird code below.
   `@Override
       public MergedResult merge() throws SQLException {
           if (1 == queryResults.size()) {
               return new IteratorStreamMergedResult(queryResults);
           }
           selectStatement.setIndexForItems(columnLabelIndexMap);
           return decorate(build());
       }`
       
   it will always return IteratorStreamMergedResult instance even it's a select request with limit.
   
   It's working at 3.0.0 with different logic, please take a look.
