Thread: calling elog possibly causing problem in DirectFunctionCall1
Hi ,<br />In certain C trigger function following code snippet causes ERROR:<br />---------------------------------------------------<br/>elog (NOTICE , "before calling DirectFunctionCall1");<br /> data->time_stamp= <br /> DirectFunctionCall1(timestamptz_in, CStringGetDatum("now"));<br />elog (NOTICE , "after callingDirectFunctionCall1");<br />----------------------------------------------------<br /><br />begin work;INSERT INTO audittest.test_table (name,foo) values ('test','test'); rollback;<br />BEGIN<br />NOTICE: before calling DirectFunctionCall1<br/>ERROR: timestamp(-1073748880) precision must be between 0 and 6<br />ROLLBACK<br /><br />If theelog before DirectFunctionCall1 is removed the code works fine. <br /><br />begin work;INSERT INTO audittest.test_table(name,foo) values ('test','test'); rollback;<br />BEGIN<br />NOTICE: after calling DirectFunctionCall1<br/>INSERT 0 1<br />ROLLBACK<br /><br />Can anyone please explain how removing a elog makes a difference?<br /><br />Regds<br />Mallah.<br /><br /><br /><br /><br /><br /><br />

Dear Sir,
thanks for the kind reply.
field time_stamp of data is declared as:
Datum time_stamp;
it is supposed to be populated with current timestamp , (now())
can you please tell me what should be passed as the third argument?

replaced it with:
data->time_stamp = DirectFunctionCall3(timestamptz_in,
CStringGetDatum("now"),
ObjectIdGetDatum(InvalidOid),
Int32GetDatum(-1))
now it works fine. (code lifted from contrib/spi/moddatetime.c(line 73)
hopefully its correct.
