I want to get daily data for this week
Question:
How to get it … ?
Answer:
We can use this query below:
SELECT time_create,DAYOFWEEK(time_create) as angka_hari, DAYNAME(time_create) as nama_hari, sum(quantity) as jumlah FROM `table_stock_in` WHERE time_create > DATE_SUB(DATE(NOW()),INTERVAL(DAYOFWEEK(NOW())-1) DAY) group by angka_hariExplain:
- DAYOFWEEK() returns the weekday index for a given date (a number from 1 to 7), 1=Sunday to 7=Saturday.
- DAYNAME() returns the day name
- DATE_SUB(DATE(NOW()),INTERVAL(DAYOFWEEK(NOW())-1) DAY) is for date subtraction “current date – ( the number day of week -1)”
Result:
| time_create | angka_hari | nama_hari | jumlah |
| 2019-09-15 20:28:10 | 1 | Sunday | 20 |
| 2019-09-16 20:28:10 | 2 | Monday | 20 |
| 2019-09-17 20:28:41 | 3 | Tuesday | 30 |
| 2019-09-18 20:28:41 | 4 | Wednesday | 40 |
| 2019-09-19 20:29:10 | 5 | Thursday | 50 |
