I want to change the date from a field in a tuple in a trigger_function
create table example ( my_date datetime ...
);
int na;
char select[20];
na = SPI_fnumber(trigdata->tg_relation->rd_att, "my_date");
memset(select, 0, sizeof(select));
sprintf(select, "1/1/2002");
newval = DirectFunctionCall1(date_in, CStringGetDatum(select));
rettuple = SPI_modifytuple(trigdata->tg_relation, rettuple, 1, &na, &newval,
NULL);
if(rettuple == NULL) elog(ERROR, "my_function: %d returned by
SPI_modifytuple", SPI_result);
when i test that my server goes down. What I missed ?
Not my function is about, but date_in.
Have anybody worked with this function ?
Can somebody give me a sample to use date_in. Thanks.
