SPI_execp — execute a statement in read/write mode
int SPI_execp(SPIPlanPtrplan
, Datum *values
, const char *nulls
, longcount
)
SPI_execp
is the same as
SPI_execute_plan
, with the latter's
read_only
parameter always taken as
false
.
plan
prepared statement (returned by SPI_prepare
)
values
An array of actual parameter values. Must have same length as the statement's number of arguments.
nulls
An array describing which parameters are null. Must have same length as the statement's number of arguments.
If nulls
is NULL
then
SPI_execp
assumes that no parameters
are null. Otherwise, each entry of the nulls
array should be ' '
if the corresponding parameter
value is non-null, or 'n'
if the corresponding parameter
value is null. (In the latter case, the actual value in the
corresponding values
entry doesn't matter.) Note
that nulls
is not a text string, just an array:
it does not need a '\0'
terminator.
count
maximum number of rows to return,
or 0
for no limit
See SPI_execute_plan
.
SPI_processed
and
SPI_tuptable
are set as in
SPI_execute
if successful.
