About data inconsistency in the same data table

1 
       I used the same table to query in two ways, one is user-defined query, the other is native query. Most of the data of the query results are accurate, but there are differences between the two values in a data point, please guide! 
                                                                                                                     
                                                                                                             Metabase rookie

You need to explain more.

  1. Post "Diagnostic Info" from Admin > Troubleshooting, and which database type you are querying.
  2. Post the query
