> For example, there is a table with two columns ,which has two hundred rows
> ,and one of the column's data is all null .When the maxRows of sql query is
> 200 ,it will only return 100 rows.The cause is that the ColumnBuffer array
> ,only expands automatically when the inserted data size exceeds 100 , but
> does not expand if the one of column data is all null.
