.SH "NAME"
SPI_keepplan \- save a prepared statement
.SH "SYNOPSIS"
.sp
.nf
int SPI_keepplan(SPIPlanPtr \fIplan\fR)
.fi
.SH "DESCRIPTION"
.PP
\fBSPI_keepplan\fR
saves a passed statement (prepared by
\fBSPI_prepare\fR) so that it will not be freed by
\fBSPI_finish\fR
nor by the transaction manager\&. This gives you the ability to reuse prepared statements in the subsequent invocations of your C function in the current session\&.
.SH "ARGUMENTS"
.PP
SPIPlanPtr \fIplan\fR
.RS 4
the prepared statement to be saved
.RE
.SH "RETURN VALUE"
.PP
0 on success;
SPI_ERROR_ARGUMENT
if
\fIplan\fR
is
NULL
or invalid
.SH "NOTES"
.PP
The passed\-in statement is relocated to permanent storage by means of pointer adjustment (no data copying is required)\&. If you later wish to delete it, use
\fBSPI_freeplan\fR
on it\&.
