Hello,
In a SPI function I have this code snippet:
double startprice = *DatumGetFloat64(SPI_getbinval(
auction_tt->vals[i], auction_tt->tupdesc,
SPI_fnumber(auction_tt->tupdesc, "startprice"), &isnull));
To extract a value from the startprice column. It only works if
"startprice" is not NULL, otherwise the backend crashes.
In the provided example SPI functions I couldn't determine a good way of
testing for NULL on columns. Should I first try to return the Datum,
test it for NULL, then run DatumGetFloat64() on it? Isn't there a
simpler way?
Thanks in advance for your help, cheers,
