c++ - const char 到 SQLCHAR 错误

Question

SELECT 语句是一个 const char，“query”必须是一个 SQLCHAR* 我试过重新解释转换，但这似乎不起作用。代码运行，即使有这个错误，但我想摆脱这个错误。线路:

SQLCHAR* query = "SELECT tblIP.[IPAddress], tblIP.[IPStatus], tblIP.[IPType] FROM tblIP ORDER BY tblIP.[IPAddress] ASC;";

错误:

IntelliSense: a value of type "const char *" cannot be used to initialize an entity of type "SQLCHAR *"

Answer 1

SQLCHAR* query = (SQLCHAR *)"SELECT tblIP.[IPAddress], tblIP.[IPStatus], tblIP.[IPType] FROM     tblIP ORDER BY tblIP.[IPAddress] ASC;";
