SPI_prepare_params - prepare a statement, without executing it yet
SPIPlanPtr SPI_prepare_params(const char * command,
void * parserSetupArg,
SPI_prepare_params creates and returns a prepared statement for the specified command, but doesn't execute the command. This function is
equivalent to SPI_prepare_cursor, with the addition that the caller can specify parser hook functions to control the parsing of external
const char * command
Parser hook setup function
void * parserSetupArg
passthrough argument for parserSetup
integer bit mask of cursor options; zero produces default behavior
SPI_prepare_params has the same return conventions as SPI_prepare.

SPI_EXECUTE_PLAN(3) PostgreSQL 9.2.7 Documentation SPI_EXECUTE_PLAN(3)NAME
SPI_execute_plan - execute a statement prepared by SPI_prepare
int SPI_execute_plan(SPIPlanPtr plan, Datum * values, const char * nulls,
bool read_only, long count)
SPI_execute_plan executes a statement prepared by SPI_prepare or one of its siblings. read_only and count have the same interpretation as
prepared statement (returned by SPI_prepare)
Datum * values
An array of actual parameter values. Must have same length as the statement's number of arguments.
const char * nulls
An array describing which parameters are null. Must have same length as the statement's number of arguments. n indicates a null value
(entry in values will be ignored); a space indicates a nonnull value (entry in values is valid).
If nulls is NULL then SPI_execute_plan assumes that no parameters are null.
true for read-only execution
maximum number of rows to return, or 0 for no limit
The return value is the same as for SPI_execute, with the following additional possible error (negative) results:
if plan is NULL or invalid, or count is less than 0
if values is NULL and plan was prepared with some parameters
SPI_processed and SPI_tuptable are set as in SPI_execute if successful.
