connect by

hi

I am trying to understand what 'connect by' is.


CREATE TABLE t (
rid NUMBER(12),
col1 VARCHAR2(30),
col2 VARCHAR2(300));

CREATE SEQUENCE seq_t_rid;

INSERT INTO t
SELECT seq_t_rid.NEXTVAL, dbms_crypto.randombytes(15), dbms_crypto.randombytes(150)
FROM DUAL
CONNECT BY LEVEL <= 1000;  -- what does CONNECT BY do ?

thanks
