13.1.14 SPI_execute_plan

Name

SPI_execute_plan -- execute a plan prepared by SPI_prepare

Synopsis

int SPI_execute_plan(SPIPlanPtr plan, Datum * values, const
 char * nulls, bool read_only, long count)

Description

SPI_execute_plan executes a plan prepared by SPI_prepare. read_only and count have the same interpretation as in SPI_execute.

Arguments

SPIPlanPtr plan

execution plan (returned by SPI_prepare)

Datum * values

An array of actual parameter values. Must have same length as the plan's number of arguments.

const char * nulls

An array describing which parameters are null. Must have same length as the plan'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.

bool read_only

true for read-only execution

long count

maximum number of rows to process or return

Return Value

The return value is the same as for SPI_execute, with the following additional possible error (negative) results:

SPI_ERROR_ARGUMENT

if plan is NULL or invalid, 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_execute if successful.
