This is the first GA release for the Connector/ODBC 5.2.x series. Now the available downloads include both a Unicode driver and an ANSI driver based on the same modern codebase. Server-side stored procedures are enabled by default.
Functionality Added or Changed
The download page now offers choices of a Unicode driver or an ANSI driver. Now users can get an ANSI driver with the combination of high performance and the latest standard-compliant behavior, rather than staying on the older 3.51 codebase.
The implementation of the
function was enhanced to support “out” and
“inout” parameters when calling stored procedures.
Designate the bind parameters intended to hold output values
from stored procedures using the type specifiers
Server-side prepared statements are now enabled by default. To
revert to the former behavior, using client-side emulation for
prepared statemnts, specify the
option when configuring the DSN.
Improved error handling for bad input data, such as an incorrect
SQLSetConnectAttr length. This fix improves
reliability in cases such as an ANSI application using a Unicode
The string returned by the
function was not null-terminated as it should be.
After executing a stored procedure returning a combination of
OUT parameters, Connector/ODB

fetching the result sets and executing a subsequent query.
Specifying certain values for the
option in the connection string could cause a serious error when
a query was executed.
