 * 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.
 *

 * In CUBRID PHP, auto-commit mode is disabled by default for
 * transaction management. It can be set by using

 * 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

 * while it is viewing table A repeatedly.  Transaction T1 may experience
