SPI_execp
SPI_execp
SPI_execp - execute a statement in read/write mode
Synopsis
int SPI_execp(SPIPlanPtrplan
, Datum *values
, const char *nulls
, longcount
)
Description
SPI_execp
is the same as
SPI_execute_plan
, with the latter's
read_only
parameter always taken as
false
.
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.
If
nulls
isNULL
thenSPI_execp
assumes that no parameters are null. Otherwise, each entry of thenulls
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 correspondingvalues
entry doesn't matter.) Note thatnulls
is not a text string, just an array: it does not need a'\0'
terminator. -
long
count
-
maximum number of rows to return, or
0
for no limit
Return Value
See
SPI_execute_plan

SPI_processed
and
SPI_tuptable

SPI_execute
if successful.
