Hi Filip,

Thank you for your report and for the proposed patch.
Unfortunately, in many places we cannot accept the changes.

Especially the ones made in the unit tests like this one:

-    (SQLPOINTER)SQL_OV_ODBC3_80, 0));
+    (SQLPOINTER)SQL_OV_ODBC3, 0));

if using SQL_OV_ODBC3_80 causes compilation error it means that UnixODBC (or another ODBC Driver Manager) is an old an unsupported version. Same goes for SQL_PARAM_INPUT_OUTPUT_STREAM.

The ODBC 3.80 functionality and streaming input-output parameters are an important part of ODBC driver and they have to be tested. If the driver manager does not support them the driver cannot work.

Anyway, the main problem as we see it is use of the dynamic libmysqlclient library instead of the static.
Changes in libmysqlclient introduced by MySQL 8.0.19 require solving some compiling and linking problems.
Our ODBC developers are working on it at the moment.
