I would like to select the rows where OutgoingInvoice.TPP field not equals the SUM of Products.IncomingSUM where the OutgoingInvoice.ID = Products.OutgoingInvoice
I wrote this SQL query:
SELECT j.* FROM OutgoingInvoice AS j
WHERE (((j.TPP)<>(select sum (jj.IncomingSUM)
from Products as jj
where jj.OutgoingInvoice = j.ID )
));
It do not shows any rows, but there are some. What do I wrong?
You could try using WHERE NOT EXISTS instead of <>
SELECT j.* FROM OutgoingInvoice AS j
WHERE NOT EXISTS(((j.TPP) = (select sum (jj.IncomingSUM) from Products as jj where jj.OutgoingInvoice = j.ID ) ));

I am trying to create a query which returns the workout percentage completion...
Workout Percentage Completion =
((Sum of LogEntries WHERE date = IN list of dates and WorkoutID =1 ) /
(Sum of all set numbers WHERE WorkoutID = 1))
x 100
Below is what I currently have, at the moment it is only returning the result of the first query.
What should I change for the query to run correctly?
SELECT
(
(
SELECT COUNT(LogEntriesID)
FROM LogEntriesTable
LEFT JOIN ExerciseWorkoutJunctionTable
ON ExerciseWorkoutJunctionTable.ExerciseWorkoutJunctionID =
LogEntriesTable.JunctionID
WHERE LogEntriesTable.date IN (
"14-05-2020", "15-05-2020", "16-05-2020", "17-05-2020",
"18-05-2020", "19-05-2020", "20-05-2020"
)
AND ExerciseWorkoutJunctionTable.WorkoutID = 1
) / (
SELECT sum(SetNumber)
FROM ExerciseWorkoutGoalsTable
LEFT JOIN ExerciseWorkoutJunctionTable
ON ExerciseWorkoutJunctionTable.ExerciseWorkoutJunctionID =
ExerciseWorkoutGoalsTable.JunctionID
WHERE ExerciseWorkoutJunctionTable.WorkoutID = 1
)
)
Your first SELECT statement is doing an OUTER JOIN but then you have a WHERE clause that is selecting non-NULL values from the ExerciseWorkoutJunctionTable table, so I suspect you might as well be doing an INNER JOIN.
When you have two queries, try:
SET #sum = (SELECT SUM(SetNumber) etc ....);
SELECT (COUNT(LogEntriesID) * 100 / #sum) AS percentage
FROM etc.
If you are using MySQL >= 8.0 you should be able to use window functions like this which breakdown your query into more readable sections.
with entries as (
SELECT COUNT(LogEntriesID) as log_entry_count
FROM LogEntriesTable as l
LEFT JOIN ExerciseWorkoutJunctionTable as e ON
e.ExerciseWorkoutJunctionID = l.JunctionID
WHERE l.date IN ("14-05-2020","15-05-2020","16-05-2020","17-05-2020","18-05-2020","19-05-2020","20-05-2020")
AND e.WorkoutID = 1
),
sets as (
SELECT sum(SetNumber) as set_sum
FROM ExerciseWorkoutGoalsTable as eg
LEFT JOIN ExerciseWorkoutJunctionTable ej
ON ej.ExerciseWorkoutJunctionID = eg.JunctionID
WHERE ej.WorkoutID = 1
)
select ((select log_entry_count from entries) / (select set_sum from sets)) * 100 as workout_completion_pct
I need to set "dph" in this table "Strobjednavka", but i don´t know whats wrong there. Please help :).
Here is my SQL script:
UPDATE STRObjednavka as o SET dph = (
SELECT dph FROM STRCena WHERE
menuKodCode =
(SELECT menuKodCode FROM STRMenu WHERE
id = o.menuId
)
AND
skupinaId =
(SELECT stravGroupId FROM grups1 WHERE
PKey =
(SELECT SGroup FROM users1 WHERE
PKey = o.userId
)))
WHERE o.price > 0 AND `date` > '2015-01-28 13:52:36' AND dph = 0;
SQL say : SQL error 1242: Subquery returns more than 1 row
You can able to update with below script, but you need to check whether update is correct or not, If you give some sample data then it will be easy to track the problem.
UPDATE STRObjednavka as o SET dph = (
SELECT max(dph) FROM STRCena WHERE
menuKodCode =
(SELECT max(menuKodCode) FROM STRMenu WHERE
id = o.menuId
)
AND
skupinaId =
(SELECT max(stravGroupId) FROM grups1 WHERE
PKey =
(SELECT max(SGroup) FROM users1 WHERE
PKey = o.userId
)))
WHERE o.price > 0 AND `date` > '2015-01-28 13:52:36' AND dph = 0;
Unfortunately, MySQL doesn't allow you to LIMIT a subquery. Depending on your use case you can add MIN or MAX to your subqueries. Here it is with MINs in all the subqueries:
UPDATE STRObjednavka as o SET dph = (
SELECT MIN(dph) FROM STRCena WHERE
menuKodCode =
(SELECT MIN(menuKodCode) FROM STRMenu WHERE
id = o.menuId
)
AND
skupinaId =
(SELECT MIN(stravGroupId) FROM grups1 WHERE
PKey =
(SELECT MIN(SGroup) FROM users1 WHERE
PKey = o.userId
)))
WHERE o.price > 0 AND `date` > '2015-01-28 13:52:36' AND dph = 0;
Although you really only need to add it to the subquery that's returning more than one row.
Your first problem is that you're writing '.... = (SELECT .... )'. Since you're using the equality operator, you're asking SQL to assign an entire column of values to a single cell. Change your equality operators before your subqueries to IN operators.
You probably should use a different query pattern.
You have this sort of thing in your query, in several places.
WHERE menuKodCode = /* !! might generate error 1242 */
(SELECT menuKodCode FROM STRMenu WHERE id = o.menuId)
There's no guarantee that your inner query won't return more than one row, and when it does, MySQL throws error 1242.
SQL works wiith sets of values. If you used IN instead of =, your query would work.
WHERE ... menuKodCode IN
(SELECT menuKodCode FROM STRMenu WHERE id = o.menuId)
But you should figure out whether that logic is correct. If I were you I'd do a whole bunch of SELECT operations to test it before doing UPDATE.
I would like to update a column from a table, and the data i want to put in is the result of a mathematical operation using subquerys that references the update table.
The problem is I want to update every row using data from the same row in the mathematical operation mentioned above.
Here's the example:
UPDATE licenses as lic
SET lic.numSessions =
(
select difference from
(select
(
select (p.numSessions * p.numMonth) as num from products p
inner join licenses l on p.idProduct = l.idProduct and l.idpatient = lic.idPatient and l.currentLicense = 1
)
-
(
SELECT COUNT(distinct s.idSession) as num
FROM sessions s
WHERE s.idPatient = lic.idPatient
AND s.dateValue >= (select l.dateCreated from licenses l where l.idPatient = lic.idPatient and l.currentLicense = 1) AND s.status = 2
)
as difference
)
x
);
EDIT:
Example of what i want:
Every row of 'licenses' has a 'idPatient'. Let's call it 'X'.
I want to see how many sessions X has done (for example 10) and then substract this number from the total number of sessions of 'X's' product have (for example 50). So the result in the update for X will be: 50 - 10 = 40.
The subqueries alone work perfectly, I'have the value of 50, then the value of 10, and then when I try to substract I have the value 40 as a column named 'difference'.
The problem I've got is that the query can't recognize the value 'lic.idPatient' inside the first subquery in the substract operation:
/* SQL Error (1054): Unknown column 'lic.idPatient' in 'on clause' */
Thanks in advance and sorry for my writing, I'm not native English.
You have to write query like this
UPDATE licenses AS licNew
SET licNew.numSessions =
(
SELECT x.difference FROM
((SELECT
(
SELECT (p.numSessions * p.numMonth) AS num FROM products p
INNER JOIN licenses l ON p.idProduct = l.idProduct AND l.idpatient = lic.idPatient AND l.currentLicense = 1
)
-
(
SELECT COUNT(DISTINCT s.idSession) AS num
FROM sessions s
WHERE s.idPatient = 6361
AND s.dateValue >= (SELECT l.dateCreated FROM licenses l WHERE l.idPatient = 6361 AND l.currentLicense = 1) AND s.status = 2
))
AS difference, lic.idPatient
FROM licenses lic
)
X WHERE licNew.idPatient = x.idPatient
);
In general, you cannot modify a table and select from the same table in a subquery.

I'm bogged in trying to figure out why query a is returning different records than query b. Both queries have seemingly same purpose yet a is returning 500 and b 3500.
this is query a:
SELECT DISTINCT ODE.OrderBillToID
FROM APTIFY.dbo.vwVwOrderDetailsKGExtended ODE
WHERE ProductID IN (2022, 1393)
AND LTRIM(RTRIM(ODE.OrderStatus)) <> 'Cancelled'
AND LTRIM(RTRIM(ODE.OrderType)) <> 'Cancellation'
AND LTRIM(RTRIM(ODE.cancellationStatus)) <> 'FULLY CANCELLED'
UNION
SELECT DISTINCT ID
FROM APTIFY.dbo.vwPersons WHERE City = 'A'
UNION
SELECT DISTINCT RecordID
FROM APTIFY.dbo.vwTopicCodeLinks WHERE TopicCodeID = 16 AND Value = 'Yes, Please'
query b:
SELECT
APTIFY..vwPersons.ID
FROM
APTIFY..vwPersons
WHERE
( APTIFY..vwPersons.ID IN (
SELECT
vwMeetingRegistrants.ID
FROM
APTIFY.dbo.vwMeetings vwMeetings
INNER JOIN APTIFY.dbo.vwMeetingRegistrants vwMeetingRegistrants
ON vwMeetings.ID=vwMeetingRegistrants.ActualMeetingID WHERE
vwMeetings.ProductID = 2022
)
OR
APTIFY..vwPersons.ID IN (
SELECT
vwMeetingRegistrants.ID
FROM
APTIFY.dbo.vwMeetings vwMeetings
INNER JOIN APTIFY.dbo.vwMeetingRegistrants vwMeetingRegistrants
ON vwMeetings.ID=vwMeetingRegistrants.ActualMeetingID WHERE
vwMeetings.ProductID = 1393
)
OR
APTIFY..vwPersons.City = N'Albany' )
OR
((
APTIFY..vwPersons.ID IN (
SELECT
RecordID
FROM
APTIFY.dbo.vwTopicCodeLinks vwTopicCodeLinks
WHERE
vwTopicCodeLinks.TopicCodeID = 16
)
AND
APTIFY..vwPersons.ID IN (
SELECT
RecordID
FROM
APTIFY.dbo.vwTopicCodeLinks vwTopicCodeLinks
WHERE
vwTopicCodeLinks.Value = N'Yes, Please'
) )
)
vwMeetingsRegistrants from the b query are producing the same records as orderkgdetailsextended from query. I cannot see ANY difference in those queries - which perhaps shows my lack of understanding the query behaviour.
BIG Thanks for any points guys! :)
As it came out, incorrectly structured query is a result of badly configured application, Aptify.
I have a master table called "parent" and a related table called "childs"
Now I run a query against the master table to update some values with the sum from the child table like this.
UPDATE master m SET
quantity1 = (SELECT SUM(quantity1) FROM childs c WHERE c.master_id = m.id),
quantity2 = (SELECT SUM(quantity2) FROM childs c WHERE c.master_id = m.id),
count = (SELECT COUNT(*) FROM childs c WHERE c.master_id = m.id)
WHERE master_id = 666;
Which works as expected but is not a good style because I basically make multiple SELECT querys on the same result. Is there a way to optimize that? (Making a query first and storing the values is not an option.
I tried this:
UPDATE master m SET (quantity1, quantity2, count) = (
SELECT SUM(quantity1), SUM(quantity2), COUNT(*)
FROM childs c WHERE c.master_id = m.id
) WHERE master_id = 666;
but that doesn't work.
Update: Here is the solution, thanks to everbody:
You can do something like this:
UPDATE master m
INNER JOIN childs c ON m.master_id = c.master_id
SET master.quantity1 = c.quantity1,
master.count = 1
If you have only one child record at a time. However if you want to use a group function like SUM() in the joined table that doesn't work. Either you get a "Invalid use of group function" if you leave the "group by" part or a "You have an error in your sql syntax if you use "GROUP BY c.master_id"
-- This doesnt work :(
UPDATE master m
INNER JOIN childs c ON m.master_id = c.master_id
SET master.quantity1 = SUM(c.quantity1),
master.count = COUNT(c.*)
GROUP by c.master_id
The solution is to use JOIN with a subquery:
UPDATE master m
INNER JOIN
(
SELECT master_id,
SUM(quantity1) as quantity1,
COUNT(*) as count
FROM childs c
GROUP BY master_id
) c
ON c.master_id = m.master_id
SET m.quantity1 = c.quantity1,
m.count = c.count
WHERE m.master_id = 666;
But since this pulls every row from the childtable the overhead would likely be bigger than using more subqueries like in the original sql. So you should add a WHERE clause to the joined table to get only the rows you need.
Another interesting approach is this syntax, which does the same as the JOIN with the WHERE clause but you should only use if if you want to update all rows with the same values and your subquery only returns one row, since the result from the subquery gets appended to the result and can be used like any column.
UPDATE master m,
(
SELECT SUM(c.quantity1) as sum_of_quantity,
COUNT(*) as rowcount FROM child c WHERE c.master_id = 666
) as c
SET m.quantity1 = c.sum_of_quantity,
m.count = c.rowcount
WHERE m.master_id = 666;
Rewriting Lieven's solution to MySQL:
UPDATE master m
JOIN (
SELECT master_id
, SUM(quantity1) as quantity1
, SUM(quantity2) as quantity2
, COUNT(*) as count
FROM childs c
GROUP BY
master_id
) c
ON c.master_id = m.master_id
SET
m.quantity1 = c.quantity1
,m.quantity2 = c.quantity2
,m.count = c.count
WHERE m.master_id = 666;
I don't know if it is allowed in MySQL, but SQL Server allows you to use the result of a select in an update.
UPDATE master m SET
quantity1 = c.quantity1
, quantity2 = c.quantity2
, count = c.count
FROM master m
INNER JOIN (
SELECT master_id
, quantity1 = SUM(quantity1)
, quantity2 = SUM(quantity2)
, count = COUNT(*)
FROM childs c
WHERE master_id = 666
GROUP BY
master_id
) c ON c.master_id = m.master_id
You could select your data into a temporary table, and then update using that data.
If you also want to insert "new" data in the same roundtrip, look into INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE ...
If you already are doing inserts if row doesn't exist, then that would be redundant with this example.
example:
INSERT INTO master m (id, quantity1, quantity2, count)
SELECT master_id, SUM(quantity1) q1, SUM(quantity2) q1, COUNT(*) c
FROM childs
GROUP BY master_id
ON DUPLICATE KEY UPDATE
m.quantity1 = q1,
m.quantity2 = q2,
m.count = c
NOTE! This is untested code, but I think it should be possible to backreference the select result in the UPDATE.
