Initializing unque_ptr

Question

ALL,

Here is my "naive" try:

std::unique_ptr<SQLWCHAR> ptr;
ptr = std::make_unique<SQLWCHAR>( "INSERT INTO mytable VALUES();" );

which results in the compilation error.

1>  c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.16.27023\include\memory(2539): error C2440: 'initializing': cannot convert from 'const char [380]' to '_Ty'
1>          with

1>              _Ty=SQLWCHAR
1>          ]
1>  c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.16.27023\include\memory(2539): note: There is no context in which this conversion is possible

What is a proper way of initializing it like this?

EDIT:

I tried to build the following on Linux with unixODBC and got the following:

Code:

std::unique_ptr<SQLWCHAR *> ptr;
ptr = std::make_unique<SQLWCHAR *>( L"INSERT INTO mytable VALUES();" );

The errors are:

EDIT2:

SINCE THE QUESTION IS INCORRECTLY CLOED I GURDS ILL CLOSE THIS BY EDITING AN OP...

I refactoring the code and so right now I don't need a smart pointer. The code looks much better and .ore maintainable

I just thought that someone will help me understand smart pointers, but unfortunately this is not the case.

Sorry for the noise...
