.SH "NAME"
SPI_commit, SPI_commit_and_chain \- commit the current transaction
.SH "SYNOPSIS"

.SH "DESCRIPTION"
.PP
\fBSPI_commit\fR
commits the current transaction\&. It is approximately equivalent to running the SQL command
\fBCOMMIT\fR\&. After the transaction is committed, a new transaction is automatically started using default transaction characteristics, so that the caller can continue using SPI facilities\&. If there is a failure during commit, the current transaction is instead rolled back and a new transaction is started, after which the error is thrown in the usual way\&.
.PP
\fBSPI_commit_and_chain\fR
is the same, but the new transaction is started with the same transaction characteristics as the just finished one, like with the SQL command
\fBCOMMIT AND CHAIN\fR\&.
.PP
These functions can only be executed if the SPI connection has been set as nonatomic in the call to
\fBSPI_connect_ext\fR\&.
