 The string is of the form "State:%s,Native:%ld,Origin:%s", where the format codes, in order, are replaced by values that describe:
 
-- The SQLSTATE, a null-terminated string containing a five-character error code returned in the *szSqlState* parameter of the ODBC function `SQLError`. SQLSTATE values are listed in Appendix A, [ODBC Error Codes](/previous-versions/windows/desktop/ms714687(v=vs.85)), in the *ODBC Programmer's Reference*. Example: "S0022".
+- The SQLSTATE, a null-terminated string containing a five-character error code returned in the *szSqlState* parameter of the ODBC function `SQLError`. SQLSTATE values are listed in Appendix A, [ODBC Error Codes](/sql/odbc/reference/appendixes/appendix-a-odbc-error-codes), in the *ODBC Programmer's Reference*. Example: "S0022".
 
 - The native error code, specific to the data source, returned in the *pfNativeError* parameter of the `SQLError` function. Example: 207.
 
 - The error message text returned in the *szErrorMsg* parameter of the `SQLError` function. This message consists of several bracketed names. As an error is passed from its source to the user, each ODBC component (data source, driver, Driver Manager) appends its own name. This information helps to pinpoint the origin of the error. Example: [Microsoft][ODBC SQL Server Driver][SQL Server]
 
 The framework interprets the error string and puts its components into `m_strStateNativeOrigin`; if `m_strStateNativeOrigin` contains information for more than one error, the errors are separated by newlines. The framework puts the alphanumeric error text into `m_strError`.
