Notable Changes

  • ODBC-66 - Support ODBC 3.8 standard The driver is now compliant with ODBC standard version 3.8. Mainly that means implementation of SQLCancelHandle API function and SQL_ATTR_RESET_CONNECTION connection attribute support.
  • ODBC-397 - Add Prepared Statement Cache to the Connector. The driver now uses cache for server side prepared statements, that allows not to re-prepare statements, but use them from the cache. Application can configure the cache with PSCACHESIZE and MAXCACHEKEY connection string options. The former sets the size of the cache, i.e. the number of statements that will be cached, the latter is the maximal size of the cache key, that effectively limits the maximum query length, that will be the value of MAXCACHEKEY - length of the current schema name - 1.

Bug Fixes

  • ODBC-389 - alloc-dealloc-mismatch in MADB_DbcFree
  • ODBC-394 - Transaction Isolataion with 11.1.1 server
  • ODBC-395 - Tansaction Isolation Level is not applied if set before connect
  • ODBC-401 - SQLCancel won't work in case of encrypted connection, and in some other cases
