You may think that the lack of auto update statistics for Memory-Optimized tables is a Microsoft oversight, but after you read this tip you will understand why it was done this way.

When you create a Memory-Optimized table, SQL Server creates statistics on index key columns.

Due to the fact that for Memory-Optimized tables statistics are not automatically updated, we must manually update statistics in order to take advantage of new statistics for In-Memory OLTP.

But this is not so simple and as you may know, even when statistics are manually updated Natively Compiled Stored Procedures seem to ignore them.

ORG_NAME = @ORG_NAME from table1 A inner join table2 B on B. SQL JOINS But this is a really hacky parlor trick, use the transaction and multiple updates, it's much more intuitive. You can update a table based on a join, you just can't have the update affect multiple tables.
