I have 2 query:
SELECT CustomerID,count(b.BookingStatus) as 'NotComplete'
FROM Booking b, Customer c
WHERE c.CustomerID=b.BookingCustomerID
AND(b.BookingStatus='Pending'
OR b.BookingStatus='OTW')
GROUP BY c.CustomerID
SELECT c.CustomerID, r.*
FROM Customer c,Regular r
WHERE c.CustomerID=r.RegularCID
Result:
How to combine these 2 result together?
also, display the zero(count) as well.
Thanks!
this is what I get after few hours of trying..obviously it's not what I want..
SELECT c.CustomerID,count(b.BookingStatus) as 'NotComplete',r.RegularID
FROM Booking b, Customer c
JOIN Regular r on r.RegularCID=c.CustomerID
WHERE c.CustomerID=b.BookingCustomerID
AND (b.BookingStatus='Pending'
or b.BookingStatus='OTW'
or b.BookingStatus='Started'
or b.BookingStatus='Unclaimed'
or b.BookingStatus='Confirmed')
GROUP by r.RegularID

You can JOIN
to the Regular
table and then LEFT JOIN
to a derived table of counts in the Booking
table. We do it this way to avoid having to GROUP BY
all the columns in the Regular
table:
SELECT c.CustomerID, r.*, b.NotComplete
FROM Customer c
JOIN Regular r ON r.RegularCID = c.CustomerID
LEFT JOIN (SELECT BookingCustomerID, COUNT(*) AS NotComplete
FROM Booking
WHERE BookingStatus IN ('Pending', 'OTW', 'Started', 'Unclaimed', 'Confirmed')
GROUP BY BookingCustomerID) b ON b.BookingCustomerID = c.CustomerID

Use join on regular
table, and subquery
on your first select
SELECT t1.*, r.RegularCID FROM (
SELECT CustomerID,count(b.BookingStatus) as 'NotComplete',
FROM Booking b
INNER JOIN Customer c ON c.CustomerID=b.BookingCustomerID
WHERE (b.BookingStatus='Pending' OR b.BookingStatus='OTW')
GROUP BY c.CustomerID) t1
LEFT JOIN Regular r on r.CustomerID = t1.CustomerID
