|
READ_UNCOMMITTED
A constant indicating that dirty reads, non-repeatable reads and phantom reads can occur. |
|
REPEATABLE_READ
A constant indicating that dirty reads and non-repeatable reads are prevented; phantom reads can occur. |
|
SERIALIZABLE
A constant indicating that dirty reads, non-repeatable reads and phantom reads are prevented. |
