.SH "NAME"
COMMIT \- commit the current transaction
.SH "SYNOPSIS"
.sp
.nf
COMMIT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
.fi
.SH "DESCRIPTION"
.PP
\fBCOMMIT\fR
commits the current transaction\&. All changes made by the transaction become visible to others and are guaranteed to be durable if a crash occurs\&.
.SH "PARAMETERS"
.PP
WORK
.br
TRANSACTION
.RS 4
Optional key words\&. They have no effect\&.
.RE
.PP
AND CHAIN
.RS 4
If
AND CHAIN
is specified, a new transaction is immediately started with the same transaction characteristics (see
SET TRANSACTION (\fBSET_TRANSACTION\fR(7))) as the just finished one\&. Otherwise, no new transaction is started\&.
.RE
.SH "NOTES"
.PP
Use
\fBROLLBACK\fR(7)
to abort a transaction\&.
.PP
Issuing
\fBCOMMIT\fR
when not inside a transaction does no harm, but it will provoke a warning message\&.
\fBCOMMIT AND CHAIN\fR
when not inside a transaction is an error\&.
.SH "EXAMPLES"
.PP
To commit the current transaction and make all changes permanent:
.sp
.if n \{\
.RS 4
.\}
.nf
COMMIT;
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
The command
\fBCOMMIT\fR
conforms to the SQL standard\&. The form
COMMIT TRANSACTION
is a PostgreSQL extension\&.
.SH "SEE ALSO"
\fBBEGIN\fR(7), \fBROLLBACK\fR(7)
