Only the source code and Windows binaries are available with this release.
The 64-bit MSI installer no longer contains 32-bit and 64-bit builds of the driver, like it did in previous versions. It now only includes 64-bit support.
The binaries for this distribution of Connector/ODBC can now connect to MySQL server accounts that use the PAM or Windows Native Authentication Plugins for authentication. See PAM Pluggable Authentication, and Windows Pluggable Authentication. These capabilities result from linking the Connector/ODBC binaries against the MySQL 5.5.16
libmysqlclient
rather than the MySQL 5.1libmysqlclient
used previously. The newerlibmysqlclient
includes the client-side support needed for the server-side PAM and Windows authentication plugins.
Some catalog functions (such as
SQLColumns()
,SQLStatistics()
, andSQLPrimaryKeys()
) would only return one row, when called after pre-execution failed. (Bug #12824839)The CLI installer script
mysqlodbc-installer
was missing documentation about how to configure the optional data source parameters. (Bug #12810058)The
Install.bat
script contained leftover3.51
information, and did not properly install the5.1
Connector/ODBC connector. (Bug #12781039)-
With the option
charset=cp1251
specified in the connection string, the results could be returned asCP1251
or asUTF8
depending on the query. For example, these queries could give results in different code pages:select if(1=1,'string in cp1251 code page',0) as 'string in cp1251 code page'; select 'string in cp1251 code page' as 'string in cp1251 code page';
(Bug #11765110, Bug #58038)
An off-by-one error, where
sqlwcharchr
might read oneSQLWCHAR
after the end of a string. (Bug #61586)SQLExecute
would returnSQL_SUCCESS_WITH_INFO
instead ofSQL_ERROR
, when column parameter binding was enabled. (Bug #59772)The Connector/ODBC driver did not call
mysql_thread_end()
when a thread ended, which caused error messages like:Error in my_thread_global_end(): 1 threads didn't exit
. (Bug #57727)When using Connector/ODBC to fetch data, if a
net_write_timeout
condition occurred, the operation returned the standard "end of data" status, rather than an error. (Bug #39878)MS Access fields with
VARCHAR NOT NULL
columns could not be altered. (Bug #31067)
