2008 R3.1 Release This release is a major release. CUBRID 3.1 Stable has been released. Several new features have been added to this version including new BLOB and CLOB data types and new APIs in JDBC/CCI which can get foreign key information. Accordingly new features are added in this CUBRID PDO version, and some bugs have been fixed. Features Added: - Add LOB (BLOB/CLOB) data support: The LOB in PDO is represented as a stream, so you can insert LOBs by binding a stream, and get LOBs by reading a stream returned by CUBRID PDO. Known issue: If column data type is CLOB, binding parameter will fail. This bug will fixed later. - Add Multipy-Query support: Now you can execute multiple queries and get results using PDOStatement->nextRowset. - Add three new schema type integer constants for cubrid_schema, which can be used to get foreign key information: CUBRID_SCH_IMPORTED_KEYS CUBRID_SCH_EXPORTED_KEYS CUBRID_SCH_CROSS_REFERENCE Features changed: - In version 8.3.0, the default value of autocommit mode is false. In this release it is changed to true. Features removed: - Remove constant CUBRID_INCLUDE_OID, because there is no methods in PDO using OID; Fixed bugs: - Fix a bug in cubrid_handle_preparer which makes user can change cursor type to scrollable cursor when preparing SQL; - Fix a bug in cubrid_handle_prepare: when binding parameter is named parameter, there will be memory leak; - Fix a bug in cubrid_handle_quoter: when escaping single quote in string, it should use double single quotes, not backslash; - Fix a bug in cubrid_handle_begin, cubrid_handle_commit and cubrid_handle_rollback: when beginning a transaction, it should commit un-commited transaction, turn off autocommit_mode, after commit or rollback, then restore the autocommit_mode; - Fix a bug in cubrid_stmt_param_hook: when the value of binding parameter is NULL, it will covert the value to empty string; - Fix a bug about cursor type: the cursor type (forward only or scrollable) should be statement attribute, not connection attribute. - Fix a bug in cubrid_schema: After array_init(return_value), when error occures, it should destroy array before return false.
