Re: Need help on updating an entire column with a list of values, I have. - Mailing list pgsql-general

Hello,

you could use an plpgsql function:

CREATE OR REPLACE FUNCTION update(numeric[])

  RETURNS void AS

$BODY$

declare

  data alias for $1;

  table_obj record;

  I integer;

Begin

    i:=0;

     for table_obj in execute select * from TABLENAME order by THE_ORDER loop

         update TABLENAME set A = data[i] where B = table_obj.B limit 1;

        I := I + 1;

     end loop;

end;

$BODY$

  LANGUAGE 'plpgsql' IMMUTABLE STRICT

And call it with:

Select update(‘{06959.0,15308.0,15968.0,18916.2,19961.0,26528.0,29553.0,29872.0,30631.0}‘)

PS: written code was not tested!
