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.
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.
Server-side prepared statements are now enabled by default. To revert to the former behavior, using client-side emulation for prepared statemnts, specify the
NO_SSPSoption when configuring the DSN. (WL #5849)
The implementation of the
SQLBindParameter()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
Improved error handling for bad input data, such as an incorrect
SQLSetConnectAttrlength. This fix improves reliability in cases such as an ANSI application using a Unicode driver. (Bug #14620420)
The string returned by the
SQLNativeSqlfunction was not null-terminated as it should be. (Bug #14559721)
After executing a stored procedure returning a combination of resultsets and
OUTparameters, Connector/ODB would be disconnected from the server. The issue occurred after fetching the result sets and executing a subsequent query. (Bug #14512187)
Specifying certain values for the
CHARSEToption in the connection string could cause a serious error when a query was executed. (Bug #14363601)
