.SH "NAME"
SPI_execp \- execute a statement in read/write mode
.SH "SYNOPSIS"
.sp
.nf
int SPI_execp(SPIPlanPtr \fIplan\fR, Datum * \fIvalues\fR, const char * \fInulls\fR, long \fIcount\fR)
.fi
.SH "DESCRIPTION"
.PP
\fBSPI_execp\fR
is the same as
\fBSPI_execute_plan\fR, with the latter\*(Aqs
\fIread_only\fR
parameter always taken as
false\&.
.SH "ARGUMENTS"
.PP
SPIPlanPtr \fIplan\fR
.RS 4
prepared statement (returned by
\fBSPI_prepare\fR)
.RE
.PP
Datum * \fIvalues\fR
.RS 4
An array of actual parameter values\&. Must have same length as the statement\*(Aqs number of arguments\&.
.RE
.PP
const char * \fInulls\fR
.RS 4
An array describing which parameters are null\&. Must have same length as the statement\*(Aqs number of arguments\&.
.sp
If
\fInulls\fR
is
NULL
then
\fBSPI_execp\fR
assumes that no parameters are null\&. Otherwise, each entry of the
\fInulls\fR
array should be
\*(Aq\ \&\*(Aq
if the corresponding parameter value is non\-null, or
\*(Aqn\*(Aq
if the corresponding parameter value is null\&. (In the latter case, the actual value in the corresponding
\fIvalues\fR
entry doesn\*(Aqt matter\&.) Note that
\fInulls\fR
is not a text string, just an array: it does not need a
\*(Aq\e0\*(Aq
terminator\&.
.RE
.PP
long \fIcount\fR
.RS 4
maximum number of rows to return, or
0
for no limit
.RE
.SH "RETURN VALUE"
.PP
See
\fBSPI_execute_plan\fR\&.
.PP
\fISPI_processed\fR
and
\fISPI_tuptable\fR
are set as in
\fBSPI_execute\fR
if successful\&.
