IGNORE LIMBO

`IGNORE LIMBO`

This flag is used to signal that records created by limbo transactions are to be ignored.Transactions are left “in limbo” if the second stage of a two-phase commit fails.

Note	Historical Note `IGNORE LIMBO` surfaces the TPB parameter `isc_tpb_ignore_limbo`, available in the API since InterBase times and is mainly used by gfix.

`RESERVING`

The RESERVING clause in the SET TRANSACTION statement reserves tables specified in the table list.Reserving a table prevents other transactions from making changes in them or even, with the inclusion of certain parameters, from reading data from them while this transaction is running.

A RESERVING clause can also be used to specify a list of tables that can be changed by other transactions, even if the transaction is started with the SNAPSHOT TABLE STABILITY isolation level.

One RESERVING clause is used to specify as many reserved tables as required.
