A transaction isolation level indicating that dirty reads are prevented; non-repeatable reads and phantom reads can occur.
A transaction isolation level indicating that dirty reads are prevented; non-repeatable reads and phantom reads can occur. This level only prohibits a transaction from reading a row with uncommitted changes in it.
A transaction isolation level indicating that dirty reads, non-repeatable reads and phantom reads can occur.
A transaction isolation level indicating that dirty reads, non-repeatable reads and phantom reads can occur. This level allows a row changed by one transaction to be readby another transaction before any changes in that row have been committed (a "dirty read"). If any of the changes are rolled back, the second transaction will have retrieved an invalid row.
A transaction isolation level indicating that dirty reads and non-repeatable reads are prevented; phantom reads can occur.
A transaction isolation level indicating that dirty reads and non-repeatable reads are prevented; phantom reads can occur. This level prohibits a transaction from reading a row with uncommitted changes in it, and it also prohibits the situation where one transaction reads a row, a second transaction alters the row, and the first transaction rereads the row, getting different values the second time (a "non-repeatable read").
A transaction isolation level indicating that dirty reads, non-repeatable reads and phantom reads are prevented.
A transaction isolation level indicating that dirty reads, non-repeatable reads and phantom
reads are prevented. This level includes the prohibitions in
TRANSACTION_REPEATABLE_READ and further prohibits the situation where one
transaction reads all rows that satisfy a WHERE condition, a second transaction
inserts a row that satisfies that WHERE condition, and the first transaction
rereads for the same condition, retrieving the additional "phantom" row in the second read.
