SPI_prepare_extended
SPI_prepare_extended
SPI_prepare_extended - prepare a statement, without executing it yet
Synopsis
SPIPlanPtr SPI_prepare_extended(const char *command
, const SPIPrepareOptions *options
)
Description
SPI_prepare_extended
creates and returns a prepared
statement for the specified command, but doesn't execute the command.
This function is equivalent to
SPI_prepare
,
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.
Arguments
-
const char *
command
-
command string
-
const SPIPrepareOptions *
options
-
struct containing optional arguments
Callers should always zero out the entire
options
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
options
fields are:
-
ParserSetupHook
parserSetup
-
Parser hook setup function
-
void *
parserSetupArg
-
pass-through argument for
parserSetup
-
RawParseMode
parseMode
-
mode for raw parsing;
RAW_PARSE_DEFAULT
(zero) produces default behavior -
int
cursorOptions
-
integer bit mask of cursor options; zero produces default behavior
Return Value
SPI_prepare_extended
has the same return conventions as
SPI_prepare
.
