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_VCLASS | Get name and type of view 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. |
