SPI_rollback, SPI_rollback_and_chain — abort the current transaction
void SPI_rollback(void)
void SPI_rollback_and_chain(void)
SPI_rollback
rolls back the current transaction. It is approximately equivalent to running the SQL command ROLLBACK
. After a transaction is rolled back, a new transaction has to be started using SPI_start_transaction
before further database actions can be executed.
SPI_rollback_and_chain
is the same, but a new transaction is immediately started with the same transaction characteristics as the just finished one, like with the SQL command ROLLBACK AND CHAIN
.
These functions can only be executed if the SPI connection has been set as nonatomic in the call to SPI_connect_ext
.
