It's an ODBC function:

SQLConnect       (
              SQLHDBC           ConnectionHandle,       /* hdbc */
              SQLCHAR           *ServerName,             /* szDSN */
              SQLSMALLINT       ServerNameLength,       /* cbDSN */
              SQLCHAR           *UserName,               /* szUID */
              SQLSMALLINT       UserNameLength,         /* cbUID */
              SQLCHAR           *Authentication,         /* szAuthStr */
              SQLSMALLINT       AuthenticationLength);


I'm needing to turn the server name that is a string object
into a char* to cast it to SQLCHAR* and I didn't find any other
function that takes const SQLCHAR* instead of SQLCHAR*. Thanks again ; )

OK. I have to ask.... what function are you calling that takes a char*? Is
there an equivalent that takes const char*?

Cheers,
