.SH "NAME"
SPI_returntuple \- prepare to return a tuple as a Datum
.\" SPI_returntuple
.SH "SYNOPSIS"
.sp
.nf
HeapTupleHeader SPI_returntuple(HeapTuple \fIrow\fR, TupleDesc \fIrowdesc\fR)
.fi
.SH "DESCRIPTION"
.PP
\fBSPI_returntuple\fR
makes a copy of a row in the upper executor context, returning it in the form of a row type
Datum\&. The returned pointer need only be converted to
Datum
via
\fBPointerGetDatum\fR
before returning\&.
.PP
Note that this should be used for functions that are declared to return composite types\&. It is not used for triggers; use
\fBSPI_copytuple\fR
for returning a modified row in a trigger\&.
.SH "ARGUMENTS"
.PP
HeapTuple \fIrow\fR
.RS 4
row to be copied
.RE
.PP
TupleDesc \fIrowdesc\fR
.RS 4
descriptor for row (pass the same descriptor each time for most effective caching)
.RE
.SH "RETURN VALUE"
.PP
HeapTupleHeader
pointing to copied row;
NULL
only if
\fIrow\fR
or
\fIrowdesc\fR
is
NULL
