Connecting
To create a connection, create an environment handle and a connection handle using SQLAllocHandle. You can then use SQLDriverConnect to provide a DSN or an ODBC connection string.
Connect to a DSN
SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv);
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0);
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"Dsn=CData Okta Source;", SQL_NTS, 0, 0, 0, 0);
Provide a Driver Connection String
SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv);
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0);
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"DRIVER={CData ODBC Driver for Okta};Domain=dev-44876464.okta.com;OAuthClientId=myId;OAuthClientSecret=mySecret;InitiateOAuth=GETANDREFRESH;", SQL_NTS, 0, 0, 0, 0);
