kalvan2019 opened a new issue #3006: 4.0.0-RC2 ResultSetMetaData  data was lost
URL: https://github.com/apache/incubator-shardingsphere/issues/3006
 
 
    
   
   ### version 4.0.0-RC2
   
   ###  question

   org.apache.shardingsphere.shardingjdbc.jdbc.core.resultset.EncryptResultSetMetaData#getLogicColumn
   
   org.apache.shardingsphere.shardingjdbc.jdbc.core.resultset.ShardingResultSetMetaData#getLogicColumn
   ```
    private String getLogicColumn(final String actualColumn) throws SQLException {
           for (Entry<String, String> entry : logicAndActualColumns.entrySet()) {
               if (entry.getValue().contains(actualColumn)) {
                   return entry.getKey();
               }
           }
           throw new SQLException(String.format("Can not get logic column by %s.", actualColumn));
       }
   ```
   
   ```
   entry.getValue().contains(actualColumn)  
   ``` 
   
   ***desc***
   
   When there are two fields in a table, one field is the content of another field, such as
   
   address
   
   certificate_address
   
   It is possible to match the columnName of certificate_address when looking up the columnName of the field address again, which results in the loss of the address field in the result set.
