SPI_execp

Name

SPI_execp -- executes a plan prepared by SPI_prepare

Synopsis

int SPI_execp(void * plan, Datum * values, const char * nulls, int count)

Description

SPI_execp executes a plan prepared by SPI_prepare. tcount has the same interpretation as in SPI_exec.

Arguments

void * plan

execution plan (returned by SPI_prepare)

Datum *values

actual parameter values

const char * nulls

An array describing which parameters are null. 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_execp assumes that no parameters are null.

int count

number of row for which plan is to be executed

Return Value

The return value is the same as for SPI_exec or one of the following:

SPI_ERROR_ARGUMENT

if plan is NULL or count is less than 0

SPI_ERROR_PARAM

if values is NULL and plan was prepared with some parameters

SPI_processed and SPI_tuptable are set as in SPI_exec if successful.

Notes

If one of the objects (a table, function, etc.) referenced by the prepared plan is dropped during the session then the result of SPI_execp for this plan will be unpredictable.
