SPI_EXECUTE_PLAN(3)					  PostgreSQL 9.2.7 Documentation				       SPI_EXECUTE_PLAN(3)

NAME

       SPI_execute_plan - execute a statement 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 statement prepared by SPI_prepare or one of its siblings.  read_only and count have the same interpretation as
       in SPI_execute.

ARGUMENTS

       SPIPlanPtr plan
	   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.

       bool read_only
	   true for read-only execution

       long count
	   maximum number of rows to return, or 0 for no limit

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.
