I have SQL code that throws up an error saying
Error: SQLCODE=-119, SQLSTATE=42803, SQLERRMC=WONUM
The code works fine until I add the group by:
select *
from workorder
left join labtrans on labtrans.refwo=workorder.wonum and labtrans.siteid=workorder.siteid
left join matusetrans on workorder.wonum=matusetrans.refwo and workorder.siteid=matusetrans.tositeid and linetype not in (select value from synonymdomain where domainid='LINETYPE' and maxvalue='TOOL')
left join locations on locations.location = workorder.location and locations.siteid=workorder.siteid
left join person on personid in (select personid from labor where laborcode = labtrans.laborcode)
left join po on workorder.wonum=po.hflwonum and workorder.siteid=po.siteid and workorder.orgid=po.orgid
left join companies on companies.company = po.vendor and companies.orgid=po.orgid
left join pluspcustomer on pluspcustomer.customer=workorder.pluspcustomer
where workorder.wonum='10192'
group by personid
;
if you only GROUP BY personid, you cannot select everything except personid, OR the fields used by aggregate functions such as SUM,MAX, etc
UPDATE
If you just want to see the duplicate personid, you could use:
select personid
from table
group by personid
But be careful here: If you write query like this, the only field that to determine the duplicate records is persionid, if you need to uniquely identify each persionid from different CompanyId, you need to group by persionid, CompanyId, otherwise, same personId from different company will be considered as the duplicate records.
But if you want to delete those duplicate records, you should use ROW_NUMBER()OVER (Partition by persionid Order by your_criteria) to delete the duplicate records. Try to do some searches to see how does that work, usually I prefer to use that function along with the CTE table expression.
if you just need to remove duplicates, use DISTINCT with your query like this:
your query:
SELECT * FROM .....
modify it:
SELECT DISTINCT * FROM .....
Hope it helps.

i have following sql in java project:
select distinct * from drivers inner join licenses on drivers.user_id=licenses.issuer_id
inner join users on drivers.user_id=users.id
where (licenses.state='ISSUED' or drivers.status='WAITING')
and users.is_deleted=false
And result i database looks like this:
And i would like to get only one result instead of two duplicated results.
How can i do that?
Solution 1 - That's Because one of data has duplicate value write distinct keyword with only column you want like this
Select distinct id, distinct creation_date, distinct modification_date from
YourTable
Solution 2 - apply distinct only on ID and once you get id you can get all data using in query
select * from yourtable where id in (select distinct id from drivers inner join
licenses
on drivers.user_id=licenses.issuer_id
inner join users on drivers.user_id=users.id
where (licenses.state='ISSUED' or drivers.status='WAITING')
and users.is_deleted=false )
Enum fields name on select, using COALESCE for fields which value is null.
usually you dont query distinct with * (all columns), because it means if one column has the same value but the rest isn't, it will be treated as a different rows. so you have to distinct only the column you want to, then get the data
I suspect that you want left joins like this:
select *
from users u left join
drivers d
on d.user_id = u.id and d.status = 'WAITING' left join
licenses l
on d.user_id = l.issuer_id and l.state = 'ISSUED'
where u.is_deleted = false and
(d.user_id is not null or l.issuer_id is not null);
I write this script in SQL server And I want get the food name with the Max of order count From this Joined Table . I can get Max value correct but when I add FoodName is select It give me an error.
SELECT S.FoodName, MAX(S.OrderCount) FROM
(SELECT FoodName,
SUM(Number) AS OrderCount
FROM tblFactor
INNER JOIN tblDetail
ON tblFactor.Factor_ID = tblDetail.Factor_ID
WHERE FactorDate = '2020-10-30'
GROUP BY FoodName)S
Here is The Error Message
Column 'S.FoodName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
also I know I can use order by and top to achieve the food Name and Max order number but I want use the way I use in this script . Thank you for your answers
If I follow you correctly, you can use ORDER BY and TOP (1) directly on the result of the join query:
SELECT TOP (1) f.FoodName, SUM(d.Number) AS OrderCount
FROM tblFactor f
INNER JOIN tblDetail d ON f.Factor_ID = d.Factor_ID
WHERE f.FactorDate = '2020-10-30'
GROUP BY f.FoodName
ORDER BY OrderCount DESC
Notes:
I added table aliases to the query, and prefixed each column with the table it (presumably !) comes from; you might need to review that, as I had to make assumptions
If you want to allow top ties, use TOP (1) WITH TIES instead
You have an aggregation function in the outer query MAX() and an unaggregated column. Hence, the database expects a GROUP BY.
Instead, use ORDER BY and LIMIT:
SELECT FoodName, SUM(Number) AS OrderCount
FROM tblFactor f INNER JOIN
tblDetail d
ON fd.Factor_ID = d.Factor_ID
WHERE FactorDate = '2020-10-30'
GROUP BY FoodName
ORDER BY OrderCount DESC
LIMIT 1;
Note: In a query that references multiple tables, you should qualify all column references. It is not clear where the columns come from, so I cannot do that for this query.
I am currently working on an assignment for my SQL class and I am stuck. I'm not looking for full code to answer the question, just a little nudge in the right direction. If you do provide full code would you mind a small explanation as to why you did it that way (so I can actually learn something.)
Here is the question:
Write a SELECT statement that returns three columns: EmailAddress, ShipmentId, and the order total for each Client. To do this, you can group the result set by the EmailAddress and ShipmentId columns. In addition, you must calculate the order total from the columns in the ShipItems table.
Write a second SELECT statement that uses the first SELECT statement in its FROM clause. The main query should return two columns: the Client’s email address and the largest order for that Client. To do this, you can group the result set by the EmailAddress column.
I am confused on how to pull in the EmailAddress column from the Clients table, as in order to join it I have to bring in other tables that aren't being used. I am assuming there is an easier way to do this using sub Queries as that is what we are working on at the time.
Think of SQL as working with sets of data as opposed to just tables. Tables are merely a set of data. So when you view data this way you immediately see that the query below returns a set of data consisting of the entirety of another set, being a table:
SELECT * FROM MyTable1
Now, if you were to only get the first two columns from MyTable1 you would return a different set that consisted only of columns 1 and 2:
SELECT col1, col2 FROM MyTable1
Now you can treat this second set, a subset of data as a "table" as well and query it like this:
SELECT
*
FROM (
SELECT
col1,
col2
FROM
MyTable1
)
This will return all the columns from the two columns provided in the inner set.
So, your inner query, which I won't write for you since you appear to be a student, and that wouldn't be right for me to give you the entire answer, would be a query consisting of a GROUP BY clause and a SUM of the order value field. But the key thing you need to understand is this set thinking: you can just wrap the ENTIRE query inside brackets and treat it as a table the way I have done above. Hopefully this helps.
You need a subquery, like this:
select emailaddress, max(OrderTotal) as MaxOrder
from
( -- Open the subquery
select Cl.emailaddress,
Sh.ShipmentID,
sum(SI.Value) as OrderTotal -- Use the line item value column in here
from Client Cl -- First table
inner join Shipments Sh -- Join the shipments
on Sh.ClientID = Cl.ClientID
inner join ShipItem SI -- Now the items
on SI.ShipmentID = Sh.ShipmentID
group by C1.emailaddress, Sh.ShipmentID -- here's your grouping for the sum() aggregation
) -- Close subquery
group by emailaddress -- group for the max()
For the first query you can join the Clients to Shipments (on ClientId).
And Shipments to the ShipItems table (on ShipmentId).
Then group the results, and count or sum the total you need.
Using aliases for the tables is usefull, certainly when you select fields from the joined tables that have the same column name.
select
c.EmailAddress,
i.ShipmentId,
SUM((i.ShipItemPrice - i.ShipItemDiscountAmount) * i.Quantity) as TotalPriceDiscounted
from ShipItems i
join Shipments s on (s.ShipmentId = i.ShipmentId)
left join Clients c on (c.ClientId = s.ClientId)
group by i.ShipmentId, c.EmailAddress
order by i.ShipmentId, c.EmailAddress;
Using that grouped query in a subquery, you can get the Maximum total per EmailAddress.
select EmailAddress,
-- max(TotalShipItems) as MaxTotalShipItems,
max(TotalPriceDiscounted) as MaxTotalPriceDiscounted
from (
select
c.EmailAddress,
-- i.ShipmentId,
-- count(*) as TotalShipItems,
SUM((i.ShipItemPrice - i.ShipItemDiscountAmount) * i.Quantity) as TotalPriceDiscounted
from ShipItems i
join Shipments s on (s.ShipmentId = i.ShipmentId)
left join Clients c on (c.ClientId = s.ClientId)
group by i.ShipmentId, c.EmailAddress
) q
group by EmailAddress
order by EmailAddress
Note that an ORDER BY is mostly meaningless inside a subquery if you don't use TOP.
I have found a few good resources that show I should be able to merge a select query with an update, but I just can't get my head around of the correct formatting.
I have a select statement that is getting info for me, and I want to pretty much use those results to Update an account table that matches the accountID in the select query.
Here is the select statement:
SELECT DISTINCT SUM(b.workers)*tt.mealTax as MealCost,b.townID,b.accountID
FROM buildings AS b
INNER JOIN town_tax AS tt ON tt.townID = b.townID
GROUP BY b.townID,b.accountID
So in short I want the above query to be merged with:
UPDATE accounts AS a
SET a.wealth = a.wealth - MealCost
Where MealCost is the result from the select query. I am sure there is a way to put this into one, I just haven't quite been able to connect the dots to get it to run consistently without separating into two queries.
First, you don't need the distinct when you have a group by.
Second, how do you intend to link the two results? The SELECT query is returning multiple rows per account (one for each town). Presumably, the accounts table has only one row. Let's say that you wanted the average MealCost for the update.
The select query to get this is:
SELECT accountID, avg(MealCost) as avg_Mealcost
FROM (SELECT SUM(b.workers)*tt.mealTax as MealCost, b.townID, b.accountID
FROM buildings AS b INNER JOIN
town_tax AS tt
ON tt.townID = b.townID
GROUP BY b.townID,b.accountID
) a
GROUP BY accountID
Now, to put this into an update, you can use syntax like the following:
UPDATE accounts
set accounts.wealth = accounts.wealth + asum.avg_mealcost
from (SELECT accountID, avg(MealCost) as avg_Mealcost
FROM (SELECT SUM(b.workers)*tt.mealTax as MealCost, b.townID, b.accountID
FROM buildings AS b INNER JOIN
town_tax AS tt
ON tt.townID = b.townID
GROUP BY b.townID,b.accountID
) a
GROUP BY accountID
) asum
where accounts.accountid = asum.accountid
This uses SQL Server syntax, which I believe is the same as for Oracle and most other databases. Mysql puts the "from" clause before the "set" and allows an alias on "update accounts".
I have 3 tables, where the first one's primary key, is the foreign key in the other 2.
I want to extract one field from the first table, and then a count from the other 2, all joined using the pk and fk. This is what I have so far:
SELECT MBDDX_STUDY.STUDY_NAME, COUNT(MBDDX_EXPERIMENT.STUDY_ID) AS NUMBER_OF_EXPERIMENTS
FROM MBDDX_STUDY
INNER JOIN MBDDX_EXPERIMENT
ON MBDDX_STUDY.ID=MBDDX_EXPERIMENT.STUDY_ID
INNER JOIN (SELECT COUNT(MBDDX_TREATMENT_GROUP.GROUP_NO) AS NUMBER_OF_GROUPS
FROM MBDDX_TREATMENT_GROUP)
ON MBDDX_TREATMENT_GROUP.STUDY_ID = MBDDX_STUDY.ID
group by MBDDX_STUDY.STUDY_NAME, MBDDX_TREATMENT_GROUP.STUDY_ID
But, i get an error saying that the MBDDX_TREATMENT_GROUP.STUDY_ID , in the penultimate line is an invalid indentifier. It is a correct table.
Any advise please.
Thanks.
You're getting the error because that column is not in your SELECT, so it can't GROUP BY a field it doesn't have.
The subquery syntax doesn't seem to make any sense to me. You've made a query that counts all rows of MBDDX_TREATMENT_GROUP, independently of the STUDY_ID, and then tries to join it into the table with a join condition that doesn't refer to anything in the subquery's results (and can't, without an alias).
Why not use a simple join? Assuming MBDDX_EXPERIMENT also has a primary key ID, you can do it with a COUNT-DISTINCT:
SELECT
MBDDX_STUDY.ID, MBDDX_STUDY.STUDY_NAME,
COUNT(DISTINCT MBDDX_EXPERIMENT.ID) AS NUMBER_OF_EXPERIMENTS
COUNT(DISTINCT MBDDX_TREATMENT_GROUP.GROUP_NO) AS NUMBER_OF_GROUPS
FROM
MBDDX_STUDY
INNER JOIN MBDDX_EXPERIMENT ON MBDDX_EXPERIMENT.STUDY_ID=MBDDX_STUDY.ID
INNER JOIN MBDDX_TREATMENT_GROUP ON MBDDX_TREATMENT_GROUP.STUDY_ID=MBDDX_STUDY.ID
GROUP BY
MBDDX_STUDY.ID, MBDDX_STUDY.STUDY_NAME
(MBDDX_STUDY.STUDY_NAME technically shouldn't be necessary to include in the GROUP BY expression according to ANSI SQL as it has a functional dependency on STUDY_ID. However it is necessary on Oracle, which can't spot the dependency.)
You don't need to group by this field (MBDDX_TREATMENT_GROUP.STUDY_ID). It should be just group by MBDDX_STUDY.STUDY_NAME
If my understanding is correct,You need a record from first table and have the count of related records in the other two tables.Here is the answer
SQL:Getting count from many tables for a user record in USER table.Whats the best approach?
It looks like you need to alias the second subquery and need to include something to join on.
It also looks like you aren't using the count you have in the subquery as well.
Try this out:
SELECT MBDDX_STUDY.STUDY_NAME
, COUNT(MBDDX_EXPERIMENT.STUDY_ID) AS NUMBER_OF_EXPERIMENTS
FROM MBDDX_STUDY
INNER JOIN MBDDX_EXPERIMENT
ON MBDDX_STUDY.ID=MBDDX_EXPERIMENT.STUDY_ID
INNER JOIN (SELECT STUDY_ID, COUNT(MBDDX_TREATMENT_GROUP.GROUP_NO) AS NUMBER_OF_GROUPS
FROM MBDDX_TREATMENT_GROUP GROUP BY MBDDX_TREATMENT_GROUP.STUDY_ID) xx
ON xx.STUDY_ID = MBDDX_STUDY.ID
GROUP BY MBDDX_STUDY.STUDY_NAME, xx.STUDY_ID
For what you really want to do, you want OUTER JOINs.
WITH number_of_experiments
AS ( SELECT study_id
, count ( * ) CNT
FROM MBDDX_EXPERIMENT
group by study_id )
, number_of_groups
as ( select study_id
, count ( * ) CNT
FROM mbddx_treatment_group
group by study_id )
select study_name
, coalesce(noex.cnt,0)
, coalesce(notr.cnt,0)
from mbddx_study
outer join number_of_experiments
as noex
using ( study_id )
outer join number_of_groups
as nogr
using ( study_id )
