Apparently #define VERSION   does not simply replace the VERSION with literal 1.0.0 but the 1.0.0 is analyzed by GCC compiler.

1. You can use Visual Studio for writing C++ applications targetting the Windows platforms.
2. If you are using UNIX (or Linux) then you are NOT using Visual Studio (and you are using a UNIX or Linux compiler, e.g. gcc).
3. SQL commands are used to deal with databases, see, for instance the SQL Wikipedia page[^].
