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

[Rajan, Pavithra]

Yes thanks -I am trying to figure writing out a script that will do the update 
than doing  individual inserts or update.I'll try this idea.

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!

 

Mit freundlichen Grüßen
