Dear MySQL users,

Please select the driver type you need based on the type of your application – Unicode or ANSI. Server-side prepared statements are enabled by default. It is suitable for use with the latest MySQL server version 8.0.

This release of the MySQL ODBC driver is conforming to the ODBC 3.8 specification. It contains implementations of key 3.8 features, including self-identification as a ODBC 3.8 driver, streaming of out for binary types only), and support of the SQL_ATTR_RESET_CONNECTION connection attribute (for the Unicode driver only).

Changes in MySQL Connector/ODBC 8.0.22 (2020-10-19, General Availability)

Functionality Added or Changed

  • For enhanced security of the existing ENABLE_LOCAL_INFILE connection string option, the new ENABLE_LOCAL_DIR option allows restricting LOCAL data loading to files located i this designated directory. Example usage:
 // LOAD LOCAL DATA DIR FROM /tmp
SQLRETURN rc =
  SQLDriverConnect(
    hdbc1,NULL,
     "DSN=myDSN;UID=root;PWD=pwd;DATABASE=test;LOAD_DATA_LOCAL_DIR=/tmp",
    SQL_NTS, conn_out, sizeof(conn_out), &conn_out_len,
    SQL_DRIVER_NOPROMPT);

// LOAD LOCAL DATA FROM EVERYWHERE
SQLRETURN rc =
  SQLDriverConnect(
    hdbc1,NULL,
    "DSN=myDSN;UID=root;PWD=pwd;DATABASE=test;ENABLE_LOCAL_INFILE=1;",
    SQL_NTS, conn_out, sizeof(conn_out), &conn_out_len,
    SQL_DRIVER_NOPROMPT);
  • Connections made using the MySQL Enterprise Edition SAS LDAP authentication plugin now are supported on Windows and Linux, but not on macOS. Connector/ODBC implement the SCRAM-SHA-1 authentication method of the SASL authentication protocol.

Bugs Fixed

  • Fixed an issue where a parameterized query could cause memory corruption. (Bug #31678876, Bug #100329)
  • Under some circumstances when using server-side prepared statements, the first row of a multi-row match was not returned with the result; while it was returned when using client-side prepared statements instead. (Bug #31373948, Bug #95423)
  • Inserting binary data (BLOBs) using SQLPutData() would report a syntax error. (Bug #31349038)
