如何正确初始化存储SQL语句的std::unique_ptr<SQLWCHAR>？

我的初步尝试代码：

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

这段代码出现编译错误：

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>          [
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

请问正确的初始化方式是什么？

编辑补充：Linux环境下的尝试 #

我在Linux环境下使用unixODBC尝试了以下代码：

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

得到如下错误：

编辑补充2 #

由于问题被错误关闭，我将通过编辑原帖结束此问题。
我重构了代码，现在不需要智能指针了，代码更简洁易维护。
我本希望有人能帮我理解智能指针，但未能如愿，抱歉打扰大家。
