.SH "NAME"
SPI_prepare_extended \- prepare a statement, without executing it yet
.SH "SYNOPSIS"
.sp
.nf
SPIPlanPtr SPI_prepare_extended(const char * \fIcommand\fR,
                                const SPIPrepareOptions * \fIoptions\fR)
.fi
.SH "DESCRIPTION"
.PP
\fBSPI_prepare_extended\fR
creates and returns a prepared statement for the specified command, but doesn\*(Aqt execute the command\&. This function is equivalent to
\fBSPI_prepare\fR, with the addition that the caller can specify options to control the parsing of external parameter references, as well as other facets of query parsing and planning\&.
.SH "ARGUMENTS"
.PP
const char * \fIcommand\fR
.RS 4
command string
.RE
.PP
const SPIPrepareOptions * \fIoptions\fR
.RS 4
struct containing optional arguments
.RE
.PP
Callers should always zero out the entire
\fIoptions\fR
struct, then fill whichever fields they want to set\&. This ensures forward compatibility of code, since any fields that are added to the struct in future will be defined to behave backwards\-compatibly if they are zero\&. The currently available
\fIoptions\fR
fields are:
.PP
ParserSetupHook \fIparserSetup\fR
.RS 4
Parser hook setup function
.RE
.PP
void * \fIparserSetupArg\fR
.RS 4
pass\-through argument for
\fIparserSetup\fR
.RE
.PP
RawParseMode \fIparseMode\fR
.RS 4
mode for raw parsing;
RAW_PARSE_DEFAULT
(zero) produces default behavior
.RE
.PP
int \fIcursorOptions\fR
.RS 4
integer bit mask of cursor options; zero produces default behavior
.RE
.SH "RETURN VALUE"
.PP
\fBSPI_prepare_extended\fR
has the same return conventions as
\fBSPI_prepare\fR\&.
