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

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(‘{06959.0,15308.0,15968.0,18916.2,19961.0,26528.0,29553.0,29872.0,306
31.0}‘)

PS: written code was not tested!

Mit freundlichen Grüßen
