A new table and streams are created with the following commands:

CREATE OR REPLACE TABLE LETTERS (ID INT, LETTER STRING) ;

CREATE OR REPLACE STREAM STREAM_1 ON TABLE LETTERS;

CREATE OR REPLACE STREAM STREAM_2 ON TABLE LETTERS APPEND_ONLY = TRUE;

The following operations are processed on the newly created table:

INSERT INTO LETTERS VALUES (1, 'A');

INSERT INTO LETTERS VALUES (2, 'B');

INSERT INTO LETTERS VALUES (3, 'C');

TRUNCATE TABLE LETTERS;

INSERT INTO LETTERS VALUES (4, 'D');

INSERT INTO LETTERS VALUES (5, 'E');

INSERT INTO LETTERS VALUES (6, 'F');

DELETE FROM LETTERS WHERE ID = 6;

What would be the output of the following SQL commands, in order?

SELECT COUNT (*) FROM STREAM_1;

SELECT COUNT (*) FROM STREAM_2;
