A SCHEMABINDING view locks the columns it uses and leaves the other columns of the table free. This post tests which changes SQL Server blocks, shows the messages and lists the bound columns with a query. It also shows how to change a bound column inside one transaction.
What is SCHEMABINDING in SQL Server Views? – Interview Question of the Week #245

Memory-Optimized Files: List Logical and Physical Names
To list memory-optimized files, join sys.dm_db_xtp_checkpoint_files to sys.database_files. This post builds a small memory-optimized database, shows the container’s logical and physical name and counts its checkpoint files by type and state. It also explains why a container holds far more disk space than its data uses.
Drop Multiple Columns in One ALTER TABLE Statement
To drop multiple columns, list them after one DROP COLUMN in one ALTER TABLE statement. This post tests the syntax on a table with a default, a check constraint and an index, shows the error that a dependent object causes and drops the constraints and columns together. It also explains why the disk space doesn’t return until a rebuild.
MAXDOP Query Hint: Override the Server Setting for One Query

This post proves it in both directions on a test table, shows that the hint can’t force a parallel plan and adds the database scoped setting between the two. Every step leaves the server setting alone.
Columnstore Indexes Without Aggregation: Do They Still Help?
Columnstore indexes without aggregation still help when a query reads many rows but only a few columns. This post builds a rowstore table and a columnstore copy of one million rows and compares reads, size and execution mode. It also shows the case where a plain b-tree index wins.
