What are the known issues with KB5021235 ?

After installing this update, there may be issues with applications that use an ODBC connection to access databases through the Microsoft ODBC SQL Server driver (sqlsrv32.dll).

These apps may fail to connect and you may receive an error message from within the app or from SQL Server, such as “The EMS system encountered a problem” Message:

[Microsoft][ODBC SQL Server Driver] Protocol error in TDS stream” or “Message: [Microsoft][ODBC SQL Server Driver]Received unknown token from SQL Server”.

It is important to note that for developers, apps affected by this issue may fail to fetch data, for example when using the SQLFetch function.

This issue may arise when the SQLBindCol function is called before SQLFetch or when the SQLGetData function is called after SQLFetch, and a value of 0 (zero) is given for the ‘bufferlength’ argument for a fixed datatype larger than 4 bytes (such as SQL_C_FLOAT).

If you are uncertain whether an app you are using is affected, you can open any app that uses the database, then open a command prompt by selecting Start, typing “command prompt” and selecting it

Then, enter the following command: tasklist /m sqlsrv32.dll. This will show you if there are any issues with the Microsoft ODBC SQL Server driver (sqlsrv32.dll). This should help you determine if any of your apps are affected by this issue.
