plpgsql

First of all, yes I've read documentation for DO statement :) http://www.postgresql.org/docs/9.1/static/sql-do.html So my question: I need to execute some dynamic block of code that contains UPDATE statements and calculate the number of all affected rows. I'm using Ado.Net provider. In Oracle the solution would have 4 steps: add InputOutput parameter "N" to command add BEGIN ... END; to command add :N := :N + sql%rowcount after each statement. It's done! We can read N parameter from command, after execute it. How can I do it with PostgreSQL? I'm using npgsql provider but can migrate to devard

I have the following function in Postgres: CREATE OR REPLACE FUNCTION point_total(user_id integer, gametime date) RETURNS bigint AS $BODY$ SELECT sum(points) AS result FROM picks WHERE user_id = $1 AND picks.gametime > $2 AND points IS NOT NULL; $BODY$ LANGUAGE sql VOLATILE; It works correctly, but when a user starts out and has no points, it very reasonably returns NULL. How can I modify it so that it returns 0 instead. Changing the body of the function to that below results in an "ERROR: syntax error at or near "IF". SELECT sum(points) AS result FROM picks WHERE user_id = $1 AND picks

I query pg_stat_activity but the contents seem to stay the same after the first time I query it within a plpgsql function body, SERIALIZABLE or REPEATABLE READ transaction. Why does pg_stat_activity not follow the rules for READ COMMITTED in a plpgsql procedure? How do I get the current status? I want to loop over a query against pg_stat_activity in plpgsql until another query running on another backend finishes. PostgreSQL makes a per-backend (per-connection, effectively) cache of the data used by the pg_stat_get_activity() function used by both pg_stat_activity and pg_stat_replication . This

I have this function in my database: CREATE OR REPLACE FUNCTION "insertarNuevoArticulo"(nombrearticulo character varying, descripcion text, idtipo integer, idfamilia bigint, artstock integer, minstock integer, maxstock integer, idmarca bigint, precio real, marcastock integer) RETURNS boolean AS $BODY$ DECLARE articulo "Articulo"%ROWTYPE; BEGIN SELECT * INTO articulo FROM "Articulo" WHERE "Nombre" = $1 AND "idTipo"=$3 AND "idFamilia"=$4; IF NOT FOUND THEN INSERT INTO "Articulo" ("Nombre", "Descripcion", "idTipo", "idFamilia", "Stock", "MinStock", "MaxStock") Values ($1, $2, $3, $4, $5, $6, $7);

I have tables that use UUIDs. I want to be able to insert a new row with or without a UUID as sometimes the client will generate the UUID other times it won't. Each table has this at it's core: CREATE TABLE IF NOT EXISTS person ( id UUID PRIMARY KEY DEFAULT gen_random_uuid() ); I'm trying to use a function to insert rows. I'd like to be able to hand a NULL id and get a default value (a generated UUID). I have something like this: CREATE OR REPLACE FUNCTION create_person( id UUID ) RETURNS BOOLEAN LANGUAGE plpgsql SECURITY DEFINER AS $$ BEGIN INSERT INTO person( id ) VALUES ( COALESCE(id

Is there anyway from within a plpgsql function that you can get the name of the function? Or even the OID of the function? I know there are some "special" variables (such as FOUND) within plpgsql, but there doesn't seem to be any way of getting this. (Although, I've read where it seems to be possible if your function is written in C). It's not critical, but it would make something I'm doing a little nicer/less fragile. I'm using PostgreSQL v. 9.1.5 For triggers use TG_NAME to get the name of the trigger (not the trigger function) fired. You also have current_query() to get the top level query
