I want to get data from last month day by day, I can get the last 30 days but I just want the month as it may be less or more than 30 days,
this is the query for getting the last 30 days
SELECT trunc(timestamp) , count(*) FROM table1 where trunc(timestamp) > trunc(sysdate -30) group by trunc(timestamp) order by 1;
Also, I am using it in a shell script if I can make a variable in the script and put it the query
CodePudding user response:
To get data from the start of the current month until today:
SELECT TRUNC(timestamp) AS day,
COUNT(*)
FROM table1
WHERE timestamp >= TRUNC(SYSDATE, 'MM')
AND timestamp < TRUNC(SYSDATE) INTERVAL '1' DAY
GROUP BY TRUNC(timestamp)
ORDER BY day
To get data from the same day last month until today:
SELECT TRUNC(timestamp) AS day,
COUNT(*)
FROM table1
WHERE timestamp >= ADD_MONTHS(TRUNC(SYSDATE), -1)
AND timestamp < TRUNC(SYSDATE) INTERVAL '1' DAY
GROUP BY TRUNC(timestamp)
ORDER BY day
