set value var via execute

[Peter Kroon <plakroon@xxxxxxxxx>]

Is it possible to set the value of a var via execute?

drop table if exists __test;

create unlogged table __test(

id int

);

DO $$

DECLARE

v_holder int;

v_table text = 'table';

v_record_0 text[];

v_id int;

BEGIN

execute '

insert into __test(id)

select id from '||v_table||' order by random() limit 2

';

v_id = (select id from __test limit 1);

 --begin this fails------------------------------------------------------------------------------------------

        v_holder = execute 'select id from '||v_table||' order by random() limit 1';

        --end this fails-------------------------------------------------------------------------------------------

v_record_0 := array(

SELECT id FROM table order by random() --limit 2

);

raise notice '%', v_record_0;

END;

$$ LANGUAGE plpgsql;
