They are standard header files in the Windows SDK. Why you don't have them is impossible to guess, be sure to use a project template to get started. — Hans Passant, May 21 '15 at 08:03

sql.h and sqlext.h is part of Windows SDK. Windows SDK is installed after installation of Visual Studio or it's possible to download Windows SDK separately - SDK is free. For example, I have these files here - it depends on SDK version:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include\sqlext.h"

Also check whether your C++ project settings has correct reference to Win SDK

In my case, the folder was `C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include`, but this got me looking in the right place. Thanks. – rstackhouse Jan 06 '17 at 20:05

If you have Windows SDK installed under Windows 8.1 or 10, then take a look under

"C:\Program Files (x86)\Windows Kits\10\Include\..."

or

"C:\Program Files (x86)\Windows Kits\8.1\Include\..."

include the following:

#include <Windows.h>
#include <sql.h>
#include <sqlext.h>
#include <sqltypes.h>
