after my last post, i tried text type and got the same issue....varchar it is thank you for your time barand

one lastthing, i want to make user_agent_checksum a unique index, but cant as its a blob, is there away around this...or will i have to make it a text type.

now that is smart way of doing it :), i wouldt even need to create a cookie garbage collector thank you for helping me, again, barand

i suppose these fields, would overall determine if a cookie exists: SELECT DISTINCT(name) , value FROM cookies WHERE user_agent_checksum = '...' AND domain = 'http://mysite.uk' AND path = '/' AND expiry > NOW() ORDER BY created DESC

thank you for your reply barand, but.... cookie id is the only key in the table which isnt present during the insert causing there never to be a duplicate key and just inserts and not update. INSERT INTO cookies (name, value, path, domain, expiry, user_agent, user_agent_checksum, ip_address, ip_address_checksum) VALUES ('test', 1, '/', 'test', DATE_ADD(NOW(), INTERVAL 22 SECOND), 1, 1 , 1, 1) ON DUPLICATE KEY UPDATE value = 1 , expiry = DATE_ADD(NOW(), INTERVAL 22 SECOND) i could just insert a new cookie/row regardless if it cookie exists...and the cookies like so? SELECT DISTINCT(name) , value FROM cookies WHERE expiry > NOW() ORDER BY created DESC unless you have a better way

hey guys im trying to create a cookie storage database...i want to update a cookie/row, but if the cookie doesnt exist i want to insert it a row, like so: UPDATE cookies SET value = 1 , expiry = DATE_ADD(NOW(), INTERVAL 22 SECOND) WHERE user_agent_checksum = 'fffff' AND name = 'test' AND domain = 'test' AND path = '/' AND expiry > NOW() AND NOT EXISTS( INSERT INTO cookies (name, value, path, domain, expiry, user_agent, user_agent_checksum, ip_addess, ip_address_checksum) VALUES ('test', 1, '/', 'test', DATE_ADD(NOW(), INTERVAL 22 SECOND), 1, 1 , 1, 1) ) but i get a error: Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO cookies (name, value, path, domain, expiry, user_agent, user_agent_c' at line 8 so my question is how do i update a cookie/row, but if it doesnt exist then to create a new one please? here is the table structure: CREATE TABLE `cookies` ( `cookie_id` int(11) NOT NULL AUTO_INCREMENT, `name` blob NOT NULL, `value` blob NOT NULL, `path` varchar(45) NOT NULL, `domain` varchar(45) NOT NULL, `ip_address` blob NOT NULL `ip_address_checksum` blob NOT NULL, `user_agent` blob NOT NULL, `user_agent_checksum` blob NOT NULL, `expiry` timestamp NOT NULL, `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (`cookie_id`) ) thank you

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 a rookie? Thank you 👍

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 😊

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 these two problems out then i think im on my way...i'll need to add the annual leave to the task time also, which isnt a issue. set @days_work = NULL; set @minutes_remaining = NULL; SELECT t.task_id , times.day_working_hours , times.username , times.task_type , times.date , times.duration_hours , times.task_start_timestamp , times.task_end_timestamp , times.day_name , times.remaining_minutes , times.days_work , times.holiday_start_timestamp , times.holiday_end_timestamp , (times.duration_hours * 60) FROM tasks t LEFT JOIN ( SELECT date , t.task_id , u.username , tt.task_type , tt.duration_hours , ot.start_timestamp as task_start_timestamp , @day_working_hours := (timestampdiff(MINUTE, och.start_time, och.finish_time) - (timestampdiff(MINUTE, och.start_time, och.finish_time) DIV 270 ) * 30) / 60 as day_working_hours , DAYNAME(date) as day_name , oal.start_timestamp as holiday_start_timestamp , oal.end_timestamp as holiday_end_timestamp , @minutes_remaining := CASE WHEN @minutes_remaining IS NULL THEN TRUNCATE((tt.duration_hours * 60) - (@day_working_hours * 60), 0) ELSE TRUNCATE(@minutes_remaining - (@day_working_hours * 60), 0) END as remaining_minutes , @days_work := CASE WHEN @days_work IS NULL AND (@day_working_hours * 60) < @minutes_remaining THEN 1 WHEN @days_work IS NOT NULL AND (@day_working_hours * 60) < @minutes_remaining OR @days_work IS NOT NULL AND @minutes_remaining > 0 THEN @days_work + 1 END as days_work , CASE WHEN (@day_working_hours * 60) > @minutes_remaining AND @minutes_remaining > 0 THEN CONCAT(DATE_ADD(date(ot.start_timestamp), INTERVAL @days_work DAY), ' ', DATE_ADD(och.start_time, INTERVAL @minutes_remaining MINUTE)) ELSE NULL END as task_end_timestamp FROM dates d LEFT JOIN operative_contracted_hours och ON weekday(date) = och.week_day JOIN operatives_tasks ot USING (user_id) JOIN tasks t USING (task_id) JOIN task_types tt USING (task_type_id) JOIN users u USING (user_id) LEFT JOIN operatives_annual_leave oal ON oal.start_timestamp < CONCAT(date, ' ', och.finish_time) AND oal.end_timestamp > CONCAT(date, ' ', och.start_time) AND och.user_id = oal.user_id ORDER BY date ) as times ON times.task_id = t.task_id hope you can help further, thank you so far

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 would only work a maximum of two days, so i had a little play around, and came up with this set @days_work = NULL; set @minutes_remaining = NULL; SELECT t.task_id , times.day_working_hours , times.username , times.task_type , times.date , times.duration_hours , times.task_start_timestamp , times.task_end_timestamp , times.day_name , times.remaining_minutes , times.days_work , times.holiday_start_timestamp , times.holiday_end_timestamp FROM tasks t LEFT JOIN ( SELECT date , t.task_id , u.username , tt.task_type , tt.duration_hours , ot.start_timestamp as task_start_timestamp , @day_working_hours := (timestampdiff(MINUTE, och.start_time, och.finish_time) - (timestampdiff(MINUTE, och.start_time, och.finish_time) DIV 270 ) * 30) / 60 as day_working_hours , DAYOFWEEK(date) as day_name , oal.start_timestamp as holiday_start_timestamp , oal.end_timestamp as holiday_end_timestamp , @days_work := IF (@day_working_hours > @minutes_remaining, IF (@days_work IS NULL, 1, @days_work + 1), NULL) as days_work , @minutes_remaining := IF (@minutes_remaining IS NULL, ((tt.duration_hours * 60) - (@day_working_hours * 60)), @minutes_remaining - (@day_working_hours * 60)) as remaining_minutes , CONCAT(IF ((@day_working_hours * 60)> @minutes_remaining , DATE_ADD(date, INTERVAL @days_work DAY), ''), ' ', IF ((@day_working_hours * 60) > @minutes_remaining, DATE_ADD(och.start_time, INTERVAL @remaining_minutes MINUTE), '')) as task_end_timestamp FROM dates d LEFT JOIN operative_contracted_hours och ON weekday(date) = och.week_day JOIN operatives_tasks ot USING (user_id) JOIN tasks t USING (task_id) JOIN task_types tt USING (task_type_id) JOIN users u USING (user_id) LEFT JOIN operatives_annual_leave oal ON oal.start_timestamp < CONCAT(date, ' ', och.finish_time) AND oal.end_timestamp > CONCAT(date, ' ', och.start_time) AND och.user_id = oal.user_id ) as times ON times.task_id = t.task_id ORDER BY task_id, date; the results are here: https://i.ibb.co/Zzn3C9z/Untitled4.png what im trying to do is caluclate the number of days work it is for the task and the minutes remaining and add them to task start date, but the problem lies with days_work and hours_remaining not corresponding with the correct date and is all muddled up. i feel if i can get the @days_work and @remaining_minutes in the right dates i can get a task end timestamp working for all different task durations thank you for your help once again barand

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 😁😁😁

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 home for 19:00 it probably make more sense to have a break on the 4th hour if entitled to breaks. would it be best for me to create a lof of if statements in the query? how is the best way for me to get the end results (task esistmated completion timestamp)? thank you again barand

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.

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.property_id = pt.property_id INNER JOIN task_types tt ON tt.task_type_id = pt.task_type_id INNER JOIN trade_task_types ttt ON ttt.task_type_id = tt.task_type_id INNER JOIN trades t ON t.trade_id = ttt.trade_id INNER JOIN departments d ON d.department_id = pt.department_id INNER JOIN property_appointments pa ON pa.property_task_id = pt.property_task_id WHERE tt.task_type = "Gas Service" AND d.department = "Gas Servicing" AND IF(pa.completed_timestamp, pa.completed_timestamp, pa.end_date) < NOW() ) UNION ALL (SELECT COUNT(pt.property_task_id) AS `count`, DATE_FORMAT(DATE_ADD(pt.created_timestamp, INTERVAL pt.priority_days DAY), "%Y-%m-%d") AS `priority_date`, d.department_id, tt.task_type_id, pt.status FROM property_tasks pt INNER JOIN properties p ON p.property_id = pt.property_id INNER JOIN task_types tt ON tt.task_type_id = pt.task_type_id INNER JOIN trade_task_types ttt ON ttt.task_type_id = tt.task_type_id INNER JOIN trades t ON t.trade_id = ttt.trade_id INNER JOIN departments d ON d.department_id = pt.department_id INNER JOIN property_appointments pa ON pa.property_task_id != pt.property_task_id WHERE tt.task_type != "Gas Service" AND d.department != "Gas Servicing" )) task_appointment INNER JOIN (SELECT u.user_id, GROUP_CONCAT(d.department_id) AS `department_ids`, GROUP_CONCAT(tt.task_type_id) AS `task_type_ids` FROM users u INNER JOIN trade_departments td ON td.user_id = u.user_id INNER JOIN departments d ON d.department_id = td.department_id INNER JOIN user_trades ut ON ut.user_id = u.user_id INNER JOIN trades t ON t.trade_id = ut.trade_id INNER JOIN trade_task_types ttt ON ttt.trade_id = t.trade_id INNER JOIN task_types tt ON tt.task_type_id = ttt.task_type_id ) user WHERE status = "Active" AND task_appointment.department_id IN (user.department_ids) AND task_appointment.task_type_id IN (user.task_type_ids) AND user.user_id = 1 ORDER BY task_appointment.priority_date ASC it comes back with the correct count which is good...any final thouhts? thank you again

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 INNER JOIN task_types tt ON tt.task_type_id = pt.task_type_id INNER JOIN trade_task_types ttt ON ttt.task_type_id = tt.task_type_id INNER JOIN trades t ON t.trade_id = ttt.trade_id INNER JOIN departments d ON d.department_id = pt.department_id INNER JOIN property_appointments pa ON pa.property_task_id = pt.property_task_id AND tt.task_type = "Gas Service" AND d.department = "Gas Servicing" AND IF(psa.completed_timestamp, psa.completed_timestamp, psa.end_date) < NOW() ) UNION ALL (SELECT COUNT(pt.property_task_id) AS `count`, DATE_FORMAT(DATE_ADD(pt.created_timestamp, INTERVAL pt.priority_days DAY), "%Y-%m-%d") 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 INNER JOIN task_types tt ON tt.task_type_id = pt.task_type_id INNER JOIN trade_task_types ttt ON ttt.task_type_id = tt.task_type_id INNER JOIN trades t ON t.trade_id = ttt.trade_id INNER JOIN departments d ON d.department_id = pt.department_id INNER JOIN property_appointments pa ON pa.property_task_id != pt.property_task_id AND tt.task_type != "Gas Service" AND d.department != "Gas Servicing" )) task_appointment INNER JOIN (SELECT GROUP_CONCAT(d.department) AS `departments`, GROUP_CONCAT(t.trade) AS `trades` FROM users u INNER JOIN trade_departments td ON td.department_id = u.user_id INNER JOIN departments d ON d.department_id = td.user_id INNER JOIN user_trades ut ON ut.user_id = u.user_id INNER JOIN trades t ON t.trade_id = ut.trade_id WHERE u.user_id = 1 ) user WHERE user.departments REGEXP REPLACE(task_appointment.department, ',', '|') > 0 AND user.trades REGEXP REPLACE(task_appointment.trades, ',', '|') > 0 AND status = "Active" ORDER BY task_appointment.priority_date ASC note the unions are almost simular but draw different rows 1st being gas servicing under certian conditions and 2nd anything else thank you

i have two CONCAT_GROUPS in my sql query, 1 being the users trades and the other being the trades required for the a particular task. What im tyring to do is to find if the user has the correct trade for a particular task. here is what ive got so far which does work, but doesnt match the words as i want, for instance if @user_trades = REPLACE('plumb,electrician', ',', '|'), it will still match for plumb SELECT @user_trades := REPLACE('plumber,electrician', ',', '|'), // regex @task_trades := 'painter,plumber', // string @task_trades REGEXP @user_trades how can i make the regex match a trade 100% or nothing thank you

i can pass the relevant ID's over infact, i don't know what i didnt do that instead of complicating things! the simpliest ways are always the best. thank you for the insight on how i could of done the query also.

im unable to find an example when it comes to select and insert in my particular case, so any help would be greatly appreciated. here is my 2 select queries which retrieve the department_id and task_type_id. what i want to do it is use those two values inside an insert as well as adding additional values. SELECT department_id FROM departments WHERE department = "Gas Servicing" SELECT task_type_id FROM task_Types WHERE task_type = "Gas Service" INSERT INTO property_appointments (property_id, department_id, task_type_id, notes, priority_days) VALUES (:property_id, ?, ?, :notes, 1) is this possible please? thank you

Beautiful stuff barand, although I've dropped the task statuses and added status, start time stamp and end timestamp to my tasks tablet and did it that way. Ps. I've still used what you've done for me previosuly but adding this will alter task times depending on task start and end, making things more accurate. Thank you again for your efforts
