Re: Help : Update and insert record based on several value in the parameter

[Tony Shelver <tshelver@xxxxxxxxx>]

I don't know what you are using as a front end to call this update, but I have been finding json/jsonb parameters passed into a function / procedure and then using postgres json functions to process the data as a good solution. 

If your data fits postgres array datatype, as others have mentioned, that is also a good (and possibly simpler) solution.

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
