Question

I try to do this, but it’s a syntax error, what am I doing wrong?

declare myid := insert into oameni values(default,'lol') returning id;

my table:

create table oameni
(
 id   serial primary key,
 name varchar(10)
);

Answer 1

You need to use the INTO clause in the RETURNING to set the value being returned into your variable:

DECLARE myid OAMENI.id%TYPE;

INSERT INTO oameni 
VALUES 
  (default,'lol') 
RETURNING id INTO myid;

You also need to specify the data type of your variable; I’m glad to see postgresql supports %TYPE and %ROWTYPE.
