Why there is separate package for SQL Native Client (SNAC) on cumulative update download page?

If you are wondering that Cumulative Update download page has a package for SNAC, should you download and install or not? Then probably you will find your answer below.


Everything about SNAC is clearly explained at following link,



Just to brief it out,


What is SNAC?

SNAC stands for SQL Native Client


Why separate package is there on download page?

It is a package only to apply updates to native client (majorly if you are using Linked Sever queries) and its size is comparatively less from whole package.


Do I need to install SNAC as well and Cumulative update package?

Answer is NO, because main cumulative update package contains SNAC updates as well


Where do I need to install SNAC?

You can install SNAC update on servers which uses this feature and don’t have either SQL Client or SQL Server installed


You can download and install SNAC components from main package as well; SNAC package comes separate just to save you some download bandwidth and time to copy the package from one server to another.


If you have SQL client or SQL server installed then better to download full cumulative update and apply.


Hope it helps!
