Help : Update and insert record based on several value in the parameter - Mailing list pgsql-general
Hi,
I want to create a function to update my table (flag='9') and insert new record (flag='0') with the rfidnumber specified in a parameter.
This parameter may have several value seperated by space (ie. 11 22 33 44)
CREATE OR REPLACE FUNCTION public.fcreate_rfid (
znumber varchar
)
RETURNS boolean AS
$body$
BEGIN
--update old record which has the same rfid number and flag='0' if exists
update tblrfid set flag='9' where flag='0' and rfidnumber in (znumber);
-- generate new record
insert into tblrfid(tanggal, flag, rfidnumber)
select localtimestamp, '0', regexp_split_to_table(znumber, ' ');
return true;
END;
$body$
LANGUAGE 'plpgsql';
when i called this function using command :
select fcreate_rfid('11 22 33 44');
This function fail to update the old record, but success to insert the new record.
Please help me how to fixed this problem. I know the problem is the update command, but i don't know the correct it. Googling anywhere didn't find any solution.
Thank you
