Changes in MySQL Connector/ODBC 8.0.20 (2020-04-27, General Availability)

  • Functionality Added or Changed
  • Bugs Fixed

Functionality Added or Changed

  • On Debian, DEB packages are now released instead of TGZ
    files. The file base names are mysql-connector-odbc-*
    (driver package) and mysql-connector-odbc-setup (setup
    package). The setup package contains the GUI
    configuration widget library ( and depends
    on the driver package. The driver package depends on the
    unixODBC libraries (libodbc, libodbcinst); and does not
    conflict with the official Debian package (libmyoodbc).

Bugs Fixed

  • When using SQL_C_WCHAR with SQLGetData, binary data was
    not returned correctly as its hexacecimal representation.
    Related, using SQL_C_CHAR with SQLGetData did return
    binary data as hex. (Bug #28864788, Bug #92429)
  • When binding an SQL_BIT type column to the SQL_C_CHAR
    type, SQLFetchScroll would return the values as an
    integer instead of a char. (Bug #28484784, Bug #91904)
