   This place can ignore the subquery column, leading to the JDBC has returned 
to the query sequence, but ShardingResultSetMetaData. GetColumnCount method 
will only return a query sequence, has resulted in the result set in the 
program for less than the value of the query sequence, looking forward to 
sharding can support the query syntax as soon as possible.
   
   One more question：
   ShardingResultSetMetaData.getColumnCount() Can I return it directly 
((ResultSetMetaData) resultSetMetaData).fields.length To solve this 
problem。thank you
