Predefined Constants

Pdo\Firebird::ATTR_DATE_FORMAT
Sets the date format.
Pdo\Firebird::ATTR_TIME_FORMAT
Sets the time format.
Pdo\Firebird::ATTR_TIMESTAMP_FORMAT
Sets the timestamp format.
Pdo\Firebird::TRANSACTION_ISOLATION_LEVEL
Attribute to sets the transaction isolation level. This can be one of Pdo\Firebird::READ_COMMITTED, Pdo\Firebird::REPEATABLE_READ, or Pdo\Firebird::SERIALIZABLE.
Pdo\Firebird::READ_COMMITTED
Flag denoting the ANSI transaction isolation level is read commited. This is the default behavior.
Pdo\Firebird::REPEATABLE_READ
Flag denoting the ANSI transaction isolation level is repeatable read. This corresponds to Firebird's "snapshot" isolation level.
Pdo\Firebird::SERIALIZABLE
Flag denoting the ANSI transaction isolation level is serializable. This corresponds to Firebird's "snapshot table stability" isolation level.
Pdo\Firebird::WRITABLE_TRANSACTION
Boolean attribute used to toggle the transaction access mode between READ ONLY and READ WRITE. By default, it is true indicating READ WRITE.
