Hi

Is there anyway I can pass a variable in the array_to_string function ?




CREATE OR REPLACE FUNCTION test1 () RETURNS void AS $$
DECLARE
foo text;
foo1 text;
begin
execute
'select ARRAY( SELECT d.COLUMN_NAME::text  from information_schema.constraint_table_usage c,
information_schema.key_column_usaged ' 
||
'where c.constraint_name=d.constraint_name and c.table_name=d.table_name and c.table_schema='
||
quote_literal(‘myschema')
||
' and c.table_schema=d.table_schema and c.constraint_name like '
||
quote_literal('%_pkey%')
||
') ' into foo;
raise notice '%', foo;
foo1 :=ARRAY_TO_STRING(foo, ', ');
raise notice '%', foo1;
END;
$$ LANGUAGE plpgsql ;


The idea is that I want to slice and dice and not run the query x amount of times



Thank you

Armand
