Predefined Constants
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
The following constants can be used when executing SQL statement. They can be passed to cubrid_prepare() and cubrid_execute().
| Constant | Description |
|---|---|
| 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. |
The following constants can be used when fetching the results to specify fetch behaviour. They can be passed to cubrid_fetch() and cubrid_fetch_array().
| Constant | Description |
|---|---|
| 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(). |
The following constants can be used when positioning the cursor in query results. They can be passed to or returned by cubrid_move_cursor().
| Constant | Description |
|---|---|
| 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. |
The following constants can be used when setting the auto-commit mode for the database connection. They can be passed to cubrid_set_autocommit() or returned by cubrid_get_autocommit().
| Constant | Description |
|---|---|
| CUBRID_AUTOCOMMIT_TRUE | Enable the auto-commit mode. |
| CUBRID_AUTOCOMMIT_FALSE | Disable the auto-commit mode. |
The following constants can be used when setting the database parameter. They can be passed to cubrid_set_db_parameter().
| Constant | Description |
|---|---|
| CUBRID_PARAM_ISOLATION_LEVEL | Transaction isolation level for the database connection. |
| CUBRID_PARAM_LOCK_TIMEOUT | Transaction timeout in seconds. |
The following constants can be used when setting the transaction isolation level. They can be passed to cubrid_set_db_parameter() or returned by cubrid_get_db_parameter().
| Constant | Description |
|---|---|
| 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. |
The following constants can be used when getting schema information. They can be passed to cubrid_schema().
| Constant | Description |
|---|---|
| CUBRID_SCH_CLASS | Get name and type of table in CUBRID. |

| 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 tow tables. |

Als je de moed voelt, kun je je vertaling aanbieden ;-)
