Enumeration of transaction types
>Enumeration of transaction typesEnumeration of transaction types
These constants define the possible flags for the optional type parameter in WHILE TRANS and KI_BEGIN.
Read-only transactions feature the same isolation guarantees as serializable transactions but with updates forbidden. Specifying both _KDB_TRANS_READONLY and _KDB_TRANS_SERIALIZABLE on the same transaction when using an Oracle database will result in an ORA-24760 (invalid isolation level flags) error - specifying _KDB_TRANS_READONLY on its own is sufficient.
