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
is `NULL then
SPI_execp
assumes that no parameters are null. Otherwise, each entry of the `nullsarray 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 `valuesentry doesn’t matter.) Note that nulls
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
