i need to add two values from two subqueries and add it to third column.
i can write whole subqueries twice to produce sum, but is there better way to do it?
SELECT
d.id,
CONCAT(d.disease, '( ', d.disease_nepali, ' ) ') AS DISEASE,
IFNULL((SELECT
patients.D_O_M + patients.D_O_F
FROM
patients
WHERE
clinic = 22
AND patients.disease = p.disease),
0) AS 'district1',
IFNULL((SELECT
patients.D_O_M + patients.D_O_F
FROM
patients
WHERE
clinic = 21 AND disease = p.disease),
0) AS 'district2'
FROM
diseases d
LEFT JOIN
patients p ON (d.id = p.disease AND p.district = 9
AND p.status = 1
AND p.report_date LIKE '2014-03%')
GROUP BY disease
You can use a sub select
SELECT t.*,t.district1 + t.district2 `new_col`
FROM (
SELECT d.id, CONCAT(d.disease, '( ' ,d.disease_nepali, ' ) ') AS DISEASE,
IFNULL((SELECT patients.D_O_M+patients.D_O_F FROM patients WHERE clinic = 22 AND patients.disease = p.disease),0) AS `district1` ,
IFNULL((SELECT patients.D_O_M+patients.D_O_F FROM patients WHERE clinic = 21 AND disease = p.disease),0) AS `district2`
FROM diseases d
LEFT JOIN patients p ON
(d.id = p.disease AND p.district = 9 AND p.status = 1 AND p.report_date LIKE '2014-03%')
GROUP BY disease
) t

This is my SQL query I am trying to select the names of employees from the employee table 'T' as trainer and 'S' as student. Where each student is linked to a trainer.
SQL query:
SELECT
cc.CourseName,
FORMAT(cs.StartDate, 'dd/MM/yyyy') AS 'Start Date',
FORMAT(cs.EndDate, 'dd/MM/yyyy') AS 'End Date',
a.AcademyName,
r.RoomName,
(SELECT e.FirstName + ' ' + e.LastName WHERE e.EmployeeType = 'T') AS 'Trainer',
(SELECT e.FirstName + ' ' + e.LastName WHERE e.EmployeeType = 'S') AS 'Student'
FROM
Employees e
INNER JOIN
CourseScheduleTrainers cst ON e.EmployeeID = cst.EmployeeID
INNER JOIN
CourseScheduleAttendees csa ON cst.TrainerID = csa.TrainerID
INNER JOIN
CourseCatalog cc ON csa.CourseCatalogID = cc.CourseCatalogID
INNER JOIN
CourseSchedule cs ON cc.CourseScheduleID = cs.CourseScheduleID
INNER JOIN
Rooms r ON cs.RoomsID = r.RoomsID
INNER JOIN
Academies a ON r.AcademyID = a.AcademyID;
This is what it is returning:
And this is an ERD of the database I am am trying to create. Essentially Course Attendees can also be classed as employees and they are labelled using the Employee Type
Entity Relationship Diagram:
I thought it was a simple case of sub querying but that doesn't seem to work.
Consider joining Employees twice and re-order the FROM and JOIN clauses to start with the main granular table, CourseScheduleAttendees, where other tables serve as lookups in a hub-spoke fashion:
SELECT cc.CourseName
,FORMAT(cs.StartDate, 'dd/MM/yyyy') AS 'Start Date'
,FORMAT(cs.EndDate, 'dd/MM/yyyy') AS 'End Date'
,a.AcademyName
,r.RoomName
,t.FirstName + ' ' + t.LastName AS 'Trainer'
,s.FirstName + ' ' + s.LastName AS 'Student'
FROM CourseScheduleAttendees csa
INNER JOIN CourseScheduleTrainers cst
ON csa.TrainerID = cst.TrainerID
INNER JOIN Employees t
ON cst.EmployeeID = t.EmployeeID
AND t.EmployeeType = 'T'
INNER JOIN Employees s
ON csa.AttendeeID = s.EmployeeID
AND s.EmployeeType = 'S'
INNER JOIN CourseCatalog cc
ON csa.CourseCatalogID = cc.CourseCatalogID
INNER JOIN CourseSchedule cs
ON cc.CourseScheduleID = cs.CourseScheduleID
INNER JOIN Rooms r
ON cs.RoomsID = r.RoomsID
INNER JOIN Academies a
ON r.AcademyID = a.AcademyID;
I am trying to create a table the shows a booking summary for a rafting business. The EER diagram shows how everything is related. I am struggling with how to show only 1 row per trip (i am returning multiple rows and the numbers are multiplied). Here is my code so far.
use www;
SELECT
d.destination_name,
tt.trip_type_name,
t.trip_number,
t.trip_date,
(e.first_name + e.last_name) AS guide_name,
t.trip_capacity,
COUNT(r.guest_id) AS guests_booked,
(COUNT(r.guest_id)-t.trip_capacity) AS positions_available
FROM
employees e,
destination d,
trip_type tt,
trips t,
reservation r
GROUP BY d.destination_name , tt.trip_type_name , t.trip_number , t.trip_date , guide_name , t.trip_capacity
ORDER BY d.destination_name , tt.trip_type_name , t.trip_date , t.trip_number;
OK so I have figured out the JOINs I am now struggling with concatenating the GUIDE NAME, it shows up as the number 0(zero). I have the same issue with another table that needs to show the guest name from a concatenated first and last name that corresponds to an id and trip number.
here is my code:
use www;
SELECT
d.destination_name,
tt.trip_type_name,
t.trip_number,
t.trip_date,
t.trip_capacity,
CONCAT(e.nick_name+' '+e.last_name AS guide_name
COUNT(r.guest_id) AS guests_booked,
(t.trip_capacity - COUNT(r.guest_id)) AS positions_available
FROM
trip_type tt
JOIN
trips t ON tt.trip_type_code = t.trip_type_code
JOIN
destination d ON t.destination_code = d.destination_code
JOIN
reservation r ON t.trip_number = r.trip_number
GROUP BY trip_number;
Second SQL query
use www;
SELECT
d.destination_name,
tt.trip_type_name,
t.trip_number,
t.trip_date,
CONCAT(e.last_name + ', ' + e.first_name) AS guide_name,
CONCAT(g.last_name + ', ' + g.first_name) AS guest_name,
ex.exp_name AS guest_experience,
g.age AS guest_age,
g.weight AS guest_weight,
g.swimmer AS guest_is_swimmer,
g.mobile_phone AS guest_mobile_phone
FROM
trip_type tt
JOIN
trips t ON tt.trip_type_code = t.trip_type_code
JOIN
destination d ON t.destination_code = d.destination_code
JOIN
reservation r ON t.trip_number = r.trip_number
JOIN
guests g ON r.guest_id = g.guest_id
JOIN
experience ex ON ex.exp_code = g.exp_code
JOIN
employees e ON t.guide_employee_id = e.employee_id
ORDER BY d.destination_name , tt.trip_type_name , t.trip_date , g.last_name , e.employee_id
You need condition on relation otherwise you obtain a cartesian product between the tables .
SELECT
d.destination_name,
tt.trip_type_name,
t.trip_number,
t.trip_date,
(e.first_name + e.last_name) AS guide_name,
t.trip_capacity,
COUNT(r.guest_id) AS guests_booked,
(COUNT(r.guest_id)-t.trip_capacity) AS positions_available
FROM trips t
inner join employees e on e.employee_id = t.employee_employee_id
inner join destination d on d.destination_code = t.destination_code
inner join trip_type tt on tt.trip_type_cde = t.trip_type_cde
inner join reservation r on r.trip_number = t.reservation_trip_number
GROUP BY d.destination_name , tt.trip_type_name , t.trip_number , t.trip_date , guide_name , t.trip_capacity
ORDER BY d.destination_name , tt.trip_type_name , t.trip_date , t.trip_number;
i have this script.. first i run query 1 and store into array then query 2,
using a foreach, i combine them and create a list of urls..but this takes time.. is there a way i can do this just in mysql by combining the table even do they have no common column?
query 1
SELECT
c.id,
c.city_name,
r.region_name,
cr.country_name
FROM city AS c, region AS r, country AS cr
WHERE r.id = c.id_region
AND cr.id = c.id_country
AND cr.id IN
(SELECT id FROM country WHERE used = 1)
query 2
SELECT id, title FROM param WHERE active = 1
loop
foreach ($arrayCity as $city) {
foreach ($arrayParam as $param ) {
$paramTitle = str_replace(' ', '+', $param['title']);
$url = 'http://url/city/'. $city['id'] .'/paramId/'. $param['id'] .'/'.
$paramTitle .'/'. $city['region_name'] .'/'. $city['city_name'];
}
}
You don't have to join on a condition. Not doing so is called a CROSS JOIN. The CROSS keyword is optional. In fact, you are already doing this because , is a synonym.
FROM city AS c, region AS r, country AS cr, param
How about
Select 'http://url/city/' + c.id + '/paramId/' + p.id + '/' +
Replace(title, ' ', '+') + '/' + r.region_Name + '/' + c.city_Name
From city c
Join region r On r.id = c.id_region
Join country n On n.id = c.id_country
cross join param p
Where n.Uused = 1
And p.active = 1
Something like this. You can select a concatenated string with results from your base table.
SELECT
c.id,
c.city_name,
r.region_name,
cr.country_name,
('http://url/city/' + c.city_name + '/' + p.param + '/' + c.id) AS URL
FROM city AS c, region AS r, country AS cr
JOIN param p ON c.id = p.id
WHERE r.id = c.id_region AND cr.id = c.id_country AND cr.id IN (SELECT id FROM country WHERE used = 1)
My experience is in TSQL, but it'll be close in my SQL
Edit: Sorry, forgot the join
The following query on my MySQL tables returns rows from the purchaseorder table that have corresponding entries in the deliveryorder table. How do I construct this query so that I get rows from the purchaseorder table even if no corresponding rows exist in the deliveryorder table? If the users want to see sql table CREATE statements, I can post those, but I'm not posting now as it really makes the question too big.
SELECT
`purchaseorder`.`id` AS `po_id`,
`purchaseorder`.`order_quantity` AS `po_order_quantity`,
`purchaseorder`.`applicable_approved_unit_rate` AS `po_unit_rate`,
`purchaseorder`.`applicable_sales_tax_rate` AS `po_tax_rate`,
`purchaseorder`.`order_date` AS `po_order_date`,
`purchaseorder`.`remarks` AS `po_remarks`,
`purchaseorder`.`is_open` AS `po_is_open`,
`purchaseorder`.`is_active` AS `po_is_active`,
`purchaseorder`.`approved_rate_id` AS `po_app_rate_id`,
`supplier`.`name` AS `sup_name`,
SUM(`deliveryorder`.`quantity`) AS `total_ordered`
FROM `purchaseorder`
LEFT JOIN `deliveryorder` ON (`deliveryorder`.`purchase_order_id` = `purchaseorder`.`id`)
INNER JOIN `approvedrate` ON (`purchaseorder`.`approved_rate_id` = `approvedrate`.`id`)
INNER JOIN `supplier` ON (`approvedrate`.`supplier_id` = `supplier`.`id`)
WHERE (
`purchaseorder`.`is_active` = 1
AND `purchaseorder`.`is_open` = 1
AND `deliveryorder`.`is_active` = 1
AND `approvedrate`.`material_id` = 2
)
HAVING `purchaseorder`.`order_quantity` >= `total_ordered` + 1
You have an aggregating function but no GROUP BY clause, which is wierd, but anyway - something like this? Oops - edited...
SELECT po.id po_id
, po.order_quantity po_order_quantity
, po.applicable_approved_unit_rate po_unit_rate
, po.applicable_sales_tax_rate po_tax_rate
, po.order_date po_order_date
, po.remarks po_remarks
, po.is_open po_is_open
, po.is_active po_is_active
, po.approved_rate_id po_app_rate_id
, s.name sup_name
, SUM(do.quantity) total_ordered
FROM purchaseorder po
LEFT
JOIN deliveryorder do
ON do.purchase_order_id = po.
AND do.is_active = 1
LEFT
JOIN approvedrate ar
ON ar.id = po.approved_rate_id
AND ar.material_id = 2
LEFT
JOIN supplier s
ON s.id = ar.supplier_id
WHERE po.is_active = 1
AND po.is_open = 1
HAVING po.order_quantity >= total_ordered + 1
I couldn't work out how to get the desired results all in one query, but ended up using the following two queries to fulfill my requirements: -
1st query
SELECT
pot.`id` AS `po_id`,
pot.`order_quantity` AS `po_order_quantity`,
pot.`applicable_approved_unit_rate` AS `po_unit_rate`,
pot.`applicable_sales_tax_rate` AS `po_tax_rate`,
pot.`is_open` AS `po_is_open`,
pot.`is_active` AS `po_is_active`,
st.`id` AS `sup_id`,
st.`name` AS `sup_name`,
SUM(dot.`quantity`) AS `total_ordered`
FROM `purchaseorder` pot
INNER JOIN `deliveryorder` dot ON (dot.`purchase_order_id` = pot.`id`)
INNER JOIN `approvedrate` art ON (pot.`approved_rate_id` = art.`id`)
INNER JOIN `supplier` st ON (art.`supplier_id` = st.`id`)
WHERE (
pot.`is_active` = 1
AND pot.`is_open` = 1
AND art.`material_id` = #materialid
AND art.`in_effect` = 1
AND art.`is_active` = 1
AND dot.`is_active` = 1
AND st.`is_active` = 1
)
HAVING pot.`order_quantity` >= `total_ordered` + #materialquantity
2nd query
SELECT
pot.`id` AS `po_id`,
pot.`order_quantity` AS `po_order_quantity`,
pot.`applicable_approved_unit_rate` AS `po_unit_rate`,
pot.`applicable_sales_tax_rate` AS `po_tax_rate`,
pot.`is_open` AS `po_is_open`,
pot.`is_active` AS `po_is_active`,
st.`id` AS `sup_id`,
st.`name` AS `sup_name`,
0 AS `total_ordered`
FROM `purchaseorder` pot
INNER JOIN `approvedrate` art ON (pot.`approved_rate_id` = art.`id`)
INNER JOIN `supplier` st ON (art.`supplier_id` = st.`id`)
WHERE (
pot.`is_active` = 1
AND pot.`is_open` = 1
AND art.`material_id` = #materialid
AND art.`in_effect` = 1
AND art.`is_active` = 1
AND st.`is_active` = 1
AND pot.`order_quantity` >= #materialquantity
AND pot.`id` NOT IN
(
SELECT dot.`purchase_order_id`
FROM `deliveryorder` dot
WHERE dot.is_active = 1
)
)
