PostgreSQL
Description
SPI_rollback
rolls back the current transaction. It is approximately equivalent to running the SQL command ROLLBACK
. After the transaction is rolled back, a new transaction is automatically started using default transaction characteristics, so that the caller can continue using SPI facilities.
SPI_rollback_and_chain
is the same, but the new transaction is 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
.
