  1. I've had numerous amounts of help from this forum for something that I have alot of passion for. Infact it was the first job I wanted to do when I grew up, but now I'm 34 haha! I played with Geocities when I was 13 then grasped how to write raw. But now I'm confident in many languages and feel I can put things together (not as well as you gurus). Anyhow, I want a career change and want to follow my kiddish dreams and work as a programmer. Start as a junior for a company, gain necessary qualifications if required and do what it is I love. Can you guys please give some advise for
  2. baramd this is beyond help, wow, thank you indeed. such a shame theres no exit statergy with the query, well its late now, so when im back on tomorrow i'll run you code and have a good tinker and get back to you. once again thank you, you didnt need to go to such efforts, but its greatly appreciated 😊
  3. Barand, can i please get some further advise, i've managed to get the end timestamp when the task is more than 2 days. But i got 2 problems, other than cleaning up the query. as seen in the picture, https://ibb.co/cbYN6BC 1. the date 24/06/2020 is the first date to subtract the remaining minutes and i don't know why, the first date subtracting minutes should be on the 23/06/2020 (total task time 1800 mins - 540 mins = 1260) 2. how do i end the query once i have a task end date? so it doesnt go through all the dates in the dates table? if i can figure thes
  4. i like that idea, i looked at the old code you helped me with which had the same principle 😁 $db->exec("CREATE TEMPORARY TABLE date_range ( date DATE PRIMARY KEY )"); $stmt = $db->prepare("INSERT INTO date_range VALUES (?)"); foreach ($dp as $date) { $d = $date->format('Y-m-d'); $stmt->execute([$d]); } regarding the query i added a dates table and inserted a number of dates ands ran the query, thank you, i increased the task duration and increased the contracted working hours on a few days while testing and saw the query
  5. hi Barand, i've digested what it is you've done, but realised that the query would work of only that scenario, so ive had a little play for the last hour and this is what i've came up with SELECT ot.task_id , tt.duration_hours , ot.start_timestamp , @start_weekday := weekday(ot.start_timestamp) , @days_work := IF (@start_weekday = 0 AND monday.shift_hours > tt.duration_hours, 0, IF (@start_weekday = 1 AND monday.shift_hours + tuesday.shift_hours > tt.duration_hours, 1, IF (@start_weekday = 2 AND monday.shift_hours + tuesday.shift_hours + wedne
  6. ooook so your a mysql geneious 😄 jeeez, to be honest im gonna have to look at the manual with what your written here, but i just ran the query and the result is beautiful i'll get onto implimenting annual holidays and bank holidays tomorrow, i'll let you know what it looks like, when its done. thank you very much barand 😁😁😁
  7. no, a user can have different work patterns, for instance a user could work monday, wednesday, friday from 8-1 each day. day 1 is correct in your scenario, but day 2 is a new day therefor if the user/operative is working from 8-4 again he/she will only be entitled to a break for 30 mins at 12.30, but break times can change depending on the users contacted hours. ie (8-12 no break) but 30 mins every 4.5 hrs is rule of thumb (daily) if working from, 08:00- 19:00, 9 hrs work the user would be entitled to 2 breaks, break at 12.00 - 12:30 then break at 16:30 - 17:00 and ho
  8. @contacted_hours := TIMEDIFF(och.finish_time, och.start_time) AS `contracted_hours`, @hours := CONCAT('2020-01-01 ', @contacted_hours), @breaks := FLOOR(CAST(TIME_TO_SEC(@hours) / (60 * 60) AS DECIMAL(10, 1)) / 4.5) AS `breaks`, @break_duration := @breaks * 30 AS `break_duration`, CAST(TIME_TO_SEC(SUBSTRING( DATE_SUB(@hours, INTERVAL @break_duration MINUTE), 12, 19)) / (60 * 60) AS DECIMAL(10, 1)) AS `shift_hours`, IF (@breaks = 1, CONCAT("{[", DATE_ADD(och.start_time, INTERVAL 270 MINUTE), ":", DATE_ADD(och.start_time, INTERVAL 300 MINUTE),"]}"), IF (@br
  9. nice to hear from you again barand , the caluclations are based on 4 variables firsly though ive noticed that i missed @contacted_hours := TIMEDIFF(och.finish_time, och.start_time) AS `contracted_hours`, from my sql SELECT u.username, tt.task_type, tt.duration_hours `task_duration_hours`, ot.start_timestamp AS `task_start_timestamp`, @task_week_day_start := WEEKDAY(ot.start_timestamp) AS `task_week_day_start`, och.shift_hours, och.week_day, och.start_time AS `operatives_start_time`, och.finish_time AS `operatives_finish_time`,
  10. after along time away from trying to progamming, im trying to get back into the swing of things. I'm trying to complete a project i once started that @Barand helped me out with many moons ago. im trying to create a scheduling programme where a task is give to a operative and added to the operatives_tasks table, which stores the start timestamp of the task. Overall what im trying to achieve is to generate a finish timestamp for the task, based on the operatives, contracted days, hours, start time end time and any annual leave he/she man have in between aswell as the task durati
  11. i will give it ago...thank you for you post kicken ?
  12. i've been playing around with nodejs sodium, and im trying to make my js scipt compatable with my php script. Both are using xchacha20poly1305m but the problem is my php encryption looks like this: (whatever it is) ��Bd���||�%��AG�wU�Q��[�V���ȷ&6����_�Y:�q��T��X��e"v� and my js encrption look like that: Uint8Array {0: 195, 1: 119, 2: 234, 3: 247, 4: 236…} theres no way of testing the compatability of both scripts when both encodings differ. here is my php <?php CONST NONCE_LENGTH = SODIUM_CRYPTO_AEAD_XCHACHA20POLY1305_IETF_NPUBBYTES; c
  13. the first select fetches properties from my properties table by thier gas expiry date, ie gas service, which is listed as a pre-task (no property_task entry). when this task is assigned to a trade it will have a property_task_id. so im selecting tasks which exists and dont yet exist for a gas service. and the second select will select anything else for that particular deparment. eg. repair on boiler, fire etc. it pull all the rows together, giving me the full list of task/pre-tasks for a selected department.
  14. thank kicken for seeing my errors, what on earth was i donig with the regex! (head shaking) ive made the changes to my query now which gets the users assigned department and task type id's and compares it with the the ids from the appointments SELECT SUM(task_appointment.count) AS `count` FROM ((SELECT COUNT(pt.property_task_id) AS `count`, p.gas_service_expiry_date AS `priority_date`, d.department_id, tt.task_type_id, pt.status FROM property_tasks pt INNER JOIN properties p ON p.pro
  15. maybe i should post in the mysql section but i really feel this is a regex issue. my query is just to count unallocated/uncompleted tasks and appointments here is the query SELECT SUM(task_appointment.count) AS `count` FROM ((SELECT COUNT(pt.property_task_id) AS `count`, p.gas_service_expiry_date AS `priority_date`, d.department, GROUP_CONCAT(t.trade) AS `trades`, pt.status FROM property_tasks pt INNER JOIN properties p ON p.property_id = pt.property_id
