Dear community,
I am sharing my node with you. I would like to pass three parameters to a stored procedure. Unfortunately, this fails with a syntax error. Can you please help me out? It concerns the part of the node shown in the screenshot.
### Procedure
```sql
CREATE OR REPLACE FUNCTION "Berger".update_(at_ numeric, waermebedarf_ numeric, flag_ character varying)
RETURNS character varying
LANGUAGE sql
AS $function$
update "Berger".messwerte
set waermebedarf = waermebedarf_, flag = flag_
where (at = at_ and flag = 'd')
or (at = at_ and flag = 'm' and waermebedarf_ > waermebedarf);
select 'ok';
;
$function$
;
```

I would create 2 separate flows. Flow 1 - creates the function, flow 2 calls the function
See the README for that node to understand how to pass parameters via the msg object.
PS, please also provide link to the PG node you are using in the [flow library](https://flows.nodered.org/search?term=postgre&type=node)
