Conformance
Version Introduced: ODBC 1.0, Deprecated

Summary
In ODBC 3.0, the SQLRemoveDefaultDataSource function has been replaced by a call to SQLConfigDataSource with an fRequest argument of ODBC_REMOVE_DEFAULT_DSN. If an ODBC 2*.x* installation program calls this function, the ODBC installer will map it to the following SQLConfigDataSource call:

SQLConfigDataSource (NULL, ODBC_REMOVE_DEFAULT_DSN, NULL, NULL)
