Question

SELECT * FROM 
(
    SELECT trunc(start_ts) ,STATUS 
    FROM table1 
) 
PIVOT (
    COUNT(STATUS) FOR STATUS in ('ERROR' error, 'COMPLETED' Completed) 
); 

Answer 1

條件start_ts > sysdate-30將限制start_ts爲最後30天。

SELECT * FROM 
(
    SELECT trunc(start_ts) ,STATUS 
    FROM table1 where start_ts > sysdate-30 
) 
PIVOT (
    COUNT(STATUS) FOR STATUS in ('ERROR' error, 'COMPLETED' Completed) 
);
