Function Calls are Evil Incarnate

The following queries look extremely innocent. However, they are all application killers once the target table grows to more than a couple thousand rows:

Select Count(*) From Person_Data Where Upper(Name_Last) = ‘SMITH’

Select Avg(Collar_Size) From Person_Data Where dbo.MyFunc(Person_Data_ID) > 500

In-Memory Databases (IMDBs)

Moore’s Law tells us that CPU’s get a LOT faster over time.  Unfortunately for the database professional, all of the secondary elements of our databases DO NOT get a lot faster over time.  Overall, the main methods of storing data since the 1960’s, magnetic tape and hard disks, have improved… Read more
