PHP 8.5.0 RC 3 available for testing

    预定义常量

    下列常量由此扩展定义，且仅在此扩展编译入 PHP 或在运行时动态载入时可用。

    以下常量可在执行 SQL 语句时使用，可传递给 cubrid_prepare() 和 cubrid_execute()。

    CUBRID SQL 执行 flag
    常量 说明
    CUBRID_INCLUDE_OID Determine whether to get OID during query execution.
    CUBRID_ASYNC Execute the query in asynchronous mode.
    CUBRID_EXEC_QUERY_ALL Execute the query in synchronous mode. This flag must be set when executing multiple SQL statements.

    以下常量可在获取结果时用于指定获取行为，可传递给 cubrid_fetch() 和 cubrid_fetch_array()。

    CUBRID 获取 flag
    常量 说明
    CUBRID_NUM Get query result as a numeric array (0-default).
    CUBRID_ASSOC Get query result as an associative array.
    CUBRID_BOTH Get query result as both numeric and associative arrays (default value).
    CUBRID_OBJECT Get query result an object.
    CUBRID_LOB The constant CUBRID_LOB can be used when you want to operate the lob object. It can be passed to cubrid_fetch(), cubrid_fetch_row(), cubrid_fetch_array(), cubrid_fetch_assoc() and cubrid_fetch_object().

    以下常量可在查询结果中定位游标时使用，可传递给或由 cubrid_move_cursor() 返回。

    CUBRID 游标定位 flag
    常量 说明
    CUBRID_CURSOR_FIRST Move current cursor to the first position in the result.
    CUBRID_CURSOR_CURRENT Move current cursor as a default value if the origin is not specified.
    CUBRID_CURSOR_LAST Move current cursor to the last position in the result.
    CUBRID_CURSOR_SUCCESS Returned value of cubrid_move_cursor() function in case of success. This flag has been removed from 8.4.1.
    CUBRID_NO_MORE_DATA Returned value of cubrid_move_cursor() function in case of failure. This flag has been removed from 8.4.1.
    CUBRID_CURSOR_ERROR Returned value of cubrid_move_cursor() function in case of failure. This flag has been removed from 8.4.1.

    以下常量可在设置数据库连接的自动提交模式时使用，可传递给 cubrid_set_autocommit() 或由 cubrid_get_autocommit() 返回。

    CUBRID 自动提交 flag
    常量 说明
    CUBRID_AUTOCOMMIT_TRUE Enable the auto-commit mode.
    CUBRID_AUTOCOMMIT_FALSE Disable the auto-commit mode.

    以下常量可在设置数据库参数时使用，可传递给 cubrid_set_db_parameter()。

    CUBRID 参数 flag
    常量 说明
    CUBRID_PARAM_ISOLATION_LEVEL Transaction isolation level for the database connection.
    CUBRID_PARAM_LOCK_TIMEOUT Transaction timeout in seconds.

    以下常量可在设置事务隔离级别时使用，可传递给 cubrid_set_db_parameter() 或由 cubrid_get_db_parameter() 返回。

    CUBRID 事务级别 flag
    常量 说明
    TRAN_COMMIT_CLASS_UNCOMMIT_INSTANCE The lowest isolation level (1). A dirty, non-repeatable or phantom read may occur for the tuple and a non-repeatable read may occur for the table as well.
    TRAN_COMMIT_CLASS_COMMIT_INSTANCE A relatively low isolation level (2). A dirty read does not occur, but non-repeatable or phantom read may occur.
    TRAN_REP_CLASS_UNCOMMIT_INSTANCE The default isolation of CUBRID (3). A dirty, non-repeatable or phantom read may occur for the tuple, but repeatable read is ensured for the table.
    TRAN_REP_CLASS_COMMIT_INSTANCE A relatively low isolation level (4). A dirty read does not occur, but non-repeatable or phantom read may.
    TRAN_REP_CLASS_REP_INSTANCE A relatively high isolation level (5). A dirty or non-repeatable read does not occur, but a phantom read may.
    TRAN_SERIALIZABLE The highest isolation level (6). Problems concerning concurrency (e.g. dirty read, non-repeatable read, phantom read, etc.) do not occur.

    以下常量可在获取模式信息时使用，可传递给 cubrid_schema()。

    CUBRID 模式 flag
    常量 说明
    CUBRID_SCH_CLASS Get name and type of table in CUBRID.
    CUBRID_SCH_VCLASS Get name and type of view in CUBRID.
    CUBRID_SCH_QUERY_SPEC Get the query definition of view.
    CUBRID_SCH_ATTRIBUTE Get the attributes of table column.
    CUBRID_SCH_CLASS_ATTRIBUTE Get the attributes of table.
    CUBRID_SCH_METHOD Get the instance method. The instance method is a method called by a class instance. It is used more often than the class method because most operations are executed in the instance.
    CUBRID_SCH_CLASS_METHOD Get the class method. The class method is a method called by a class object. It is usually used to create a new class instance or to initialize it. It is also used to access or update class attributes.
    CUBRID_SCH_METHOD_FILE Get the information of the file where the method of the table is defined.
    CUBRID_SCH_SUPERCLASS Get the name and type of table which table inherites attributes from.
    CUBRID_SCH_SUBCLASS Get the name and type of table which inherites attributes from this table.
    CUBRID_SCH_CONSTRAINT Get the table constraints.
    CUBRID_SCH_TRIGGER Get the table triggers.
    CUBRID_SCH_CLASS_PRIVILEGE Get the privilege information of table.
    CUBRID_SCH_ATTR_PRIVILEGE Get the privilege information of column.
    CUBRID_SCH_DIRECT_SUPER_CLASS Get the direct super table of table.
    CUBRID_SCH_PRIMARY_KEY Get the table primary key.
    CUBRID_SCH_IMPORTED_KEYS Get imported keys of table.
    CUBRID_SCH_EXPORTED_KEYS Get exported keys of table.
    CUBRID_SCH_CROSS_REFERENCE Get reference relationship of two tables.

    以下常量可在报告错误时使用，可由 cubrid_error_code_facility() 返回。

    CUBRID 错误设施（facility）代码
    常量 说明
    CUBRID_FACILITY_DBMS The error occurred in CUBRID dbms.
    CUBRID_FACILITY_CAS The error occurred in CUBRID broker cas.
    CUBRID_FACILITY_CCI The error occurred in CUBRID cci.
    CUBRID_FACILITY_CLIENT The error occurred in CUBRID PHP client.
