Bugs fixed:
Security Enhancement:
Accessing a parameer with the type of
SQL_C_CHAR
, but with a numeric type and a
length of zero, the parameter marker would get stropped from the
query. In addition, an SQL injection was possible if the
parameter value had a nonzero length and was not numeric, the
text would be inserted verbatim.
(Bug#34575)
Important Change:
In previous versions, the SSL certificate would automatically be
verified when used as part of the MySQL Connector/ODBC connection. The
default mode is now to ignore the verificate of certificates. To
enforce verification of the SSL certificate during connection,
use the SSLVERIFY
DSN parameter, setting the
value to 1.
(Bug#29955, Bug#34648)
When using ADO, the count of parameters in a query would always return zero. (Bug#33298)
Using tables with a single quote or other nonstandard characters in the table or column names through ODBC would fail. (Bug#32989)
When using Crystal Reports, table and column names would be truncated to 21 characters, and truncated columns in tables where the truncated name was the duplicated would lead to only a single column being displayed. (Bug#32864)
SQLExtendedFetch()
and
SQLFetchScroll()
ignored the rowset size if
the Don't cache result
DSN option was set.
(Bug#32420)
When using the ODBC SQL_TXN_READ_COMMITTED
option, 'dirty' records would be read from tables as if the
option had not been applied.
(Bug#31959)
When creating a System DSN using the ODBC Administrator on Mac OS X, a User DSN would be created instead. The root cause is a problem with the iODBC driver manager used on Mac OS X. The fix works around this issue.
ODBC Administrator may still be unable to register a System
DSN unless the /Library/ODBC/odbc.ini
file has the correct permissions. You should ensure that the
file is writable by the admin
group.
Calling SQLFetch
or
SQLFetchScroll
would return negative data
lengths when using SQL_C_WCHAR
.
(Bug#31220)
SQLSetParam()
caused memory allocation errors
due to driver manager's mapping of deprecated functions (buffer
length -1).
(Bug#29871)
Static cursor was unable to be used through ADO when dynamic cursors were enabled. (Bug#27351)
Using connection.Execute
to create a record
set based on a table without declaring the cmd option as
adCmdTable
will fail when communicating with
versions of MySQL 5.0.37 and higher. The issue is related to the
way that SQLSTATE
is returned when ADO tries
to confirm the existence of the target object.
(Bug#27158)
Updating a RecordSet
when the query involves
a BLOB
field would fail.
(Bug#19065)
With some connections to MySQL databases using MySQL Connector/ODBC, the connection would mistakenly report 'user cancelled' for accesses to the database information. (Bug#16653)
