* Description
|

*
|

*
|
||||
*
|
||||
*
|
||||
* PARAM_ISOLATION_LEVEL
|
||||
* The transaction isolation level.
|
||||
*
|
||||
*
|
||||
* LOCK_TIMEOUT
|
||||
* CUBRID provides the lock timeout feature, which sets the waiting
|
||||
* time (in seconds) for the lock until the transaction lock setting is
|
||||
* allowed. The default value of the lock_timeout_in_secs parameter is
|
||||
* -1, which means the application client will wait indefinitely until
|
||||
* the transaction lock is allowed.
|
||||
*
|
||||
*
|
||||
*
|
||||
* PARAM_AUTO_COMMIT
|
||||
* In CUBRID PHP, auto-commit mode is disabled by default for
|
||||
* transaction management. It can be set by using
|
||||
* cubrid_set_autocommit.
|
||||
*
|
||||
*
|
||||
*
|
||||
*
|
||||
*
|
||||
*
|
||||
* The following table shows the isolation levels from 1 to 6. It consists of
|
||||
* table schema (row) and isolation level:

|
||||
* Levels of Isolation Supported by CUBRID

* Description
|
||||
*
|
||||
*
|
||||
*
|
||||
*
|
||||
* SERIALIZABLE (6)
|
||||
* In this isolation level, problems concerning concurrency (e.g.
|
||||
* dirty read, non-repeatable read, phantom read, etc.) do not
|
||||
* occur.
|
||||
*
|
||||
*
|
||||
* REPEATABLE READ CLASS with REPEATABLE READ INSTANCES (5)
|
||||
* Another transaction T2 cannot update the schema of table A while
|
||||
* transaction T1 is viewing table A.
|
||||
* Transaction T1 may experience phantom read for the record R that was
|
||||
* inserted by another transaction T2 when it is repeatedly retrieving a
|
||||
* specific record.
|
||||
*
|
||||
*
|
||||
* REPEATABLE READ CLASS with READ COMMITTED INSTANCES (or CURSOR STABILITY) (4)
|
||||
* Another transaction T2 cannot update the schema of table A while
|
||||
* transaction T1 is viewing table A.
|
||||
* Transaction T1 may experience R read (non-repeatable read) that was
|
||||
* updated and committed by another transaction T2 when it is repeatedly
|
||||
* retrieving the record R.
|
||||
*
|
||||
*
|
||||
* REPEATABLE READ CLASS with READ UNCOMMITTED INSTANCES (3)
|
||||
* Default isolation level. Another transaction T2 cannot update
|
||||
* the schema of table A while transaction T1 is viewing table A.
|
||||
* Transaction T1 may experience R' read (dirty read) for the record that
|
||||
* was updated but not committed by another transaction T2.
|
||||
*
|
||||
*
|
||||
* READ COMMITTED CLASS with READ COMMITTED INSTANCES (2)
|
||||
* Transaction T1 may experience A' read (non-repeatable read) for
|
||||
* the table that was updated and committed by another transaction T2
|
||||
* while it is viewing table A repeatedly. Transaction T1 may experience
|
||||
* R' read (non-repeatable read) for the record that was updated and

* committed by another transaction T2 while it is retrieving the record
|
||||
* R repeatedly.
|

*
|

* READ COMMITTED CLASS with READ UNCOMMITTED INSTANCES (1)
