Explanation:
Table A: Auto_update statistics off
Table A does not change much. There is no need to update the statistics on this table.
Table B: SET AUTO_UPDATE_STATISTICS_ASYNC ON
You can set the database to update statistics asynchronously:
ALTER DATABASE YourDBName
SET AUTO_UPDATE_STATISTICS_ASYNC ON
If you enable this option then the Query Optimizer will run the query first and update the outdated statistics afterwards. When you set this option to OFF, the Query Optimizer will update the outdated statistics before compiling the query. This option can be useful in OLTP environments References: https://www.mssqltips.com/sqlservertip/2766/sql-server-auto-update-and-auto-create- statistics-options/
