Trying to Compare 2 Tables with Multiple Joins - mysql

I'm trying to compare 2 tables, but can't seem to get it to work. It's probably something very basic. Here's my code:
Select bin, partno, count(*) from
(SELECT parts.partno, location.bin
FROM inventory
INNER JOIN location
ON inventory.locid = location.locid
INNER JOIN parts
ON inventory.partid = parts.partid
WHERE loc = 'PnP'
UNION
select partno, bin from dlyfeedercontents) t
Group By t.bin, t.partno
HAVING COUNT(*) = 1
ORDER BY bin
Here are the results:
08-01 3052-93-7100-0C6 1
08-01 3052-93-7100-0C6 1
08-01 Test2 1
08-02 3052-90-7100-063 1
08-02 3052-90-7100-063 1
I can't seem to get the Group or Count to acknowledge that there are duplicates (for example, the first 2 lines). The results of the UNION are what I expected.

I'm not quite sure what you are trying to do, but I strongly suspect the problem is using union rather than union all. union removes duplicates. Does this version do what you want?
select bin, partno, count(*)
from ((SELECT parts.partno, location.bin
FROM inventory INNER JOIN
location
ON inventory.locid = location.locid INNER JOIN
parts
ON inventory.partid = parts.partid
WHERE loc = 'PnP'
) union all
(select partno, bin
from dlyfeedercontents
)
) t
Group By t.bin, t.partno
HAVING COUNT(*) = 1
ORDER BY bin;

The issue was a nonprinting character in some of the data (/r)! Thanks for all who helped!

MySQL Query to fetch Distinct Rows with latest status

I have 3 tables, namely - areas, works and jobs.
areas works jobs
----- ----- -----
area_id work_id area_id (FK)
area_name task work_id (FK)
area_type app_area status
updated_at
I'm trying to select the total list of areas cross joined with works such that I have all the permutations for areas vs works, then have the LATEST status of that combination, if it exists. I want distinct rows for each area_id-work_id combination.
I put together the below query statement but some rows have statuses displayed as NULL when they actually exist. My guess is there's something wrong with my inner SELECT statement but try as I may, I could not get it to work, any idea what's wrong with my statement?
SELECT area_name, works.task, jobs.status
FROM areas
CROSS JOIN works ON works.work_id = works.work_id
LEFT JOIN jobs ON jobs.status = (SELECT jobs.status FROM jobs ORDER BY jobs.updated_at DESC LIMIT 1) AND
(jobs.work_id = works.work_id AND jobs.area_id = areas.area_id)
WHERE works.app_area = 'zone' AND areas.area_type = 'zone'
ORDER BY areas.area_id, works.work_id, jobs.updated_at;
Your logic for the last status should be using the date not the status. The logic looks like this:
SELECT a.area_name, w.task, j.status
FROM areas a CROSS JOIN
works w LEFT JOIN
jobs j
ON j.work_id = w.work_id AND j.area_id = a.area_id AND
j.updated_at = (SELECT MAX(j2.updated_at)
FROM jobs j2
WHERE j2.work_id = w.work_id AND j2.area_id = a.area_id
)
WHERE w.app_area = 'zone' AND a.area_type = 'zone'
ORDER BY a.area_id, w.work_id, j.updated_at;
This also fixes some other problems, such as having an ON clause with CROSS JOIN.
If you want to solve it by your own query then please replace this line in the left join sub query
SELECT j.status FROM jobs j ORDER BY jobs.updated_at DESC LIMIT 1
Using Gordon Solution, I think this is another way you can do it. you'll have to test to see which way works faster for you.
SELECT a.area_name, w.task, (SELECT MAX(j2.updated_at)
FROM jobs j2
WHERE j2.work_id = w.work_id AND j2.area_id = a.area_id
) status
FROM areas a CROSS JOIN
works w LEFT JOIN
jobs j
ON j.work_id = w.work_id AND j.area_id = a.area_id
WHERE w.app_area = 'zone' AND a.area_type = 'zone'
ORDER BY a.area_id, w.work_id, j.updated_at;

Mysql Query modify

This is my Query I want to get latest record in each group.I have two table t_service_request and t_request_chkpoint
t_service_request
------------
LTS,JFT,CUS_NO,REQUETST_ID...
t_request_chkpoint
------------
LTS ,REQUETST_ID...
Both table match by REQUETST_ID.
I want to group by cus_no in table t_service_request
SELECT S.*, A.ID as CID, A.ENTRY_ID, A.LTS
FROM maintenance.t_service_request S
WHERE JFT IN (
SELECT MAX(JFT)
FROM maintenance.t_service_request
GROUP BY CUS_NO
) LEFT OUTER JOIN maintenance.t_request_chkpoint A
ON S.REQUEST_ID = A.REQUEST_ID where S.COMPANY_ID = '0002' AND S.STATE >= 3 AND A.STATE >= 3
but didn't work any suggestions ?
t_service_request
------------
LTS|JFT|CUS_NO|REQUETST_ID|
t_request_chkpoint
------------
|LTS|REQUETST_ID|
Join above two table(Request_id) and select latest JFT in each CUS_NO
Try this, maybe works;)
SELECT DISTINCT
S.*,
A.ID AS CID,
A.ENTRY_ID,
A.LTS
FROM maintenance.t_service_request S
LEFT JOIN maintenance.t_request_chkpoint A ON A.REQUETST_ID = S.REQUETST_ID AND A.STATE >= 3
WHERE S.JFT = (SELECT MAX(B.JFT)
FROM maintenance.t_service_request B
WHERE B.CUS_NO = S.CUS_NO
GROUP BY B.CUS_NO)
AND S.COMPANY_ID = '0002' AND S.STATE >= 3
I think your sql may have some syntax errors and I am not sure I've misunderstood your requirement or not.
I must admit, I still don't understand what you are asking. Your query, however, is incomplete, and maybe fixing it solves your problem already.
You say you want "to get latest record in each group" and in your query you are looking for the maximum JFT per CUS_NO. Then, however you are only comparing the JFT and not the CUS_NO.
Moreover, your query is syntactically incorrect, as it has two WHERE clauses. Last but not least, (outer) join criteria (state >= 3 here) belongs in the ON clause, not in the WHERE clause.
Here is the corrected query:
select
sr.*,
rc.id as cid,
rc.entry_id,
rc.lts
from maintenance.t_service_request sr
left outer join maintenance.t_request_chkpoint rc on rc.request_id = sr.request_id
and rc.state >= 3
where sr.company_id = '0002' and sr.state >= 3
and (sr.cus_no, sr.jft) in
(
select cus_no, max(jft)
from maintenance.t_service_request
group by cus_no
);

Subquery for SQL

I need assistance in joining the two query statements together using subquery. I am confused on how I can combine the two together. I appreciate the help.
SELECT * FROM MEDICAL_PROCEDURE
JOIN PROCEDURE_CATEGORY ON medical_procedure.procedure_category_id = PROCEDURE_CATEGORY.PROCEDURE_CATEGORY_ID;
SELECT
Medical_procedure.medical_procedure_id,
COUNT(procedure_tool_supply.medical_procedure_id) AS Supply_Needed
FROM Procedure_tool_supply
JOIN Medical_Procedure on Procedure_tool_supply.medical_procedure_id = Medical_procedure.medical_procedure_id
GROUP BY Procedure_tool_supply.medical_procedure_id
HAVING COUNT(Procedure_tool_supply.medical_procedure_id) < 3;
Can't really test without test data, but this should work. Hopefully I figured out correctly what you're trying to do:
SELECT *
FROM
MEDICAL_PROCEDURE P
JOIN PROCEDURE_CATEGORY C ON
P.procedure_category_id = C.PROCEDURE_CATEGORY_ID
cross apply (
SELECT
COUNT(T.medical_procedure_id) AS Supply_Needed
FROM
Procedure_tool_supply T
where
T.medical_procedure_id = P.medical_procedure_id
GROUP BY
T.medical_procedure_id
HAVING
COUNT(T.medical_procedure_id) < 3
) T
It's not clear what you are trying to achieve. But if your intent is to include the derived Supply_Needed column from the second query on each row from the first query, and to restrict the rows returned to those that have a medical_procedure_id value returned by the second query, then...
you could do something like this:
SELECT mp.*
, pc.*
, ct.Supply_Needed
FROM MEDICAL_PROCEDURE mp
JOIN PROCEDURE_CATEGORY pc
ON mp.procedure_category_id = pc.PROCEDURE_CATEGORY_ID
JOIN ( SELECT pr.medical_procedure_id
, COUNT(ts.medical_procedure_id) AS Supply_Needed
FROM Procedure_tool_supply ts
JOIN Medical_Procedure pr
ON ts.medical_procedure_id = pr.medical_procedure_id
GROUP BY ts.medical_procedure_id
HAVING COUNT(ts.medical_procedure_id) < 3
) ct
ON ct.medical_procedure_id = mp.medical_procedure_id

MySql subselect havning where clause with value from main select

there's select which i'm trying to make work
SELECT DISTINCT a.client_key, client_name
FROM Bloggers AS a
LEFT JOIN BloggersPosts AS b
ON a.client_key = b.client_key
WHERE a.status = 1 AND
0 NOT IN (SELECT MIN(STATUS) FROM BloggersPosts AS c WHERE c.client_key=a.client_key)
For some reason 0 NOT IN (SELECT MIN(STATUS) FROM BloggersPosts AS c WHERE c.client_key=a.client_key) is not working, any ideas how to make it work?
EDIT: by not working i mean that if i delete the susbelect - my query gives result rows. But as soon as I add it - there is empty result. At the same time when i execute the subselect alone SELECT MIN(STATUS) FROM BloggersPosts - it returns 1, which means that putting it as subselect - should return results too, but it doesn't.
Thank you
I hope this will do your job. Trying different solution for your problem.
SELECT DISTINCT a.client_key, client_name
FROM Bloggers AS a
JOIN (SELECT client_key, MIN(STATUS) minstatus FROM BloggersPosts GROUP BY client_key) b
ON a.client_key = b.client_key AND minstatus <> 0
WHERE a.status = 1
Use JOIN instead, something like similar:
SELECT DISTINCT a.client_key, client_name, MIN(c.STATUS) blog_status
FROM Bloggers AS a
LEFT JOIN BloggersPosts AS b ON a.client_key = b.client_key
LEFT JOIN BloggersPosts AS c ON c.client_key = a.client_key
WHERE a.status = 1
HAVING blog_status <> 0

MySQL Inner Join with where clause sorting and limit, subquery?

Everything in the following query results in one line for each invBlueprintTypes row with the correct information. But I'm trying to add something to it. See below the codeblock.
Select
blueprintType.typeID,
blueprintType.typeName Blueprint,
productType.typeID,
productType.typeName Item,
productType.portionSize,
blueprintType.basePrice * 0.9 As bpoPrice,
productGroup.groupName ItemGroup,
productCategory.categoryName ItemCategory,
blueprints.productionTime,
blueprints.techLevel,
blueprints.researchProductivityTime,
blueprints.researchMaterialTime,
blueprints.researchCopyTime,
blueprints.researchTechTime,
blueprints.productivityModifier,
blueprints.materialModifier,
blueprints.wasteFactor,
blueprints.maxProductionLimit,
blueprints.blueprintTypeID
From
invBlueprintTypes As blueprints
Inner Join invTypes As blueprintType On blueprints.blueprintTypeID = blueprintType.typeID
Inner Join invTypes As productType On blueprints.productTypeID = productType.typeID
Inner Join invGroups As productGroup On productType.groupID = productGroup.groupID
Inner Join invCategories As productCategory On productGroup.categoryID = productCategory.categoryID
Where
blueprints.techLevel = 1 And
blueprintType.published = 1 And
productType.marketGroupID Is Not Null And
blueprintType.basePrice > 0
So what I need to get in here is the following table with the columns below it so I can use the values timestamp and sort the entire result by profitHour
tablename: invBlueprintTypesPrices
columns: blueprintTypeID, timestamp, profitHour
I need this information with the following select in mind. Using a select to show my intention of the JOIN/in-query select or whatever that can do this.
SELECT * FROM invBlueprintTypesPrices
WHERE blueprintTypeID = blueprintType.typeID
ORDER BY timestamp DESC LIMIT 1
And I need the main row from table invBlueprintTypes to still show even if there is no result from the invBlueprintTypesPrices. The LIMIT 1 is because I want the newest row possible, but deleting the older data is not a option since history is needed.
If I've understood correctly I think I need a subquery select, but how to do that? I've tired adding the exact query that is above with a AS blueprintPrices after the query's closing ), but did not work with a error with the
WHERE blueprintTypeID = blueprintType.typeID
part being the focus of the error. I have no idea why. Anyone who can solve this?
You'll need to use a LEFT JOIN to check for NULL values in invBlueprintTypesPrices. To mimic the LIMIT 1 per TypeId, you can use the MAX() or to truly make sure you only return a single record, use a row number -- this depends on whether you can have multiple max time stamps for each type id. Assuming not, then this should be close:
Select
...
From
invBlueprintTypes As blueprints
Inner Join invTypes As blueprintType On blueprints.blueprintTypeID = blueprintType.typeID
Inner Join invTypes As productType On blueprints.productTypeID = productType.typeID
Inner Join invGroups As productGroup On productType.groupID = productGroup.groupID
Inner Join invCategories As productCategory On productGroup.categoryID = productCategory.categoryID
Left Join (
SELECT MAX(TimeStamp) MaxTime, TypeId
FROM invBlueprintTypesPrices
GROUP BY TypeId
) blueprintTypePrice On blueprints.blueprintTypeID = blueprintTypePrice.typeID
Left Join invBlueprintTypesPrices blueprintTypePrices On
blueprintTypePrice.TypeId = blueprintTypePrices.TypeId AND
blueprintTypePrice.MaxTime = blueprintTypePrices.TimeStamp
Where
blueprints.techLevel = 1 And
blueprintType.published = 1 And
productType.marketGroupID Is Not Null And
blueprintType.basePrice > 0
Order By
blueprintTypePrices.profitHour
Assuming you might have the same max time stamp with 2 different records, replace the 2 left joins above with something similar to this getting the row number:
Left Join (
SELECT #rn:=IF(#prevTypeId=TypeId,#rn+1,1) rn,
TimeStamp,
TypeId,
profitHour,
#prevTypeId:=TypeId
FROM (SELECT *
FROM invBlueprintTypesPrices
ORDER BY TypeId, TimeStamp DESC) t
JOIN (SELECT #rn:=0) t2
) blueprintTypePrices On blueprints.blueprintTypeID = blueprintTypePrices.typeID AND blueprintTypePrices.rn=1
You don't say where you are putting the subquery. If in the select clause, then you have a problem because you are returning more than one value.
You can't put this into the from clause directly, because you have a correlated subquery (not allowed).
Instead, you can put it in like this:
from . . .
(select *
from invBLueprintTypesPrices ibptp
where ibtp.timestamp = (select ibptp2.timestamp
from invBLueprintTypesPrices ibptp2
where ibptp.blueprintTypeId = ibptp2.blueprintTypeId
order by timestamp desc
limit 1
)
) ibptp
on ibptp.blueprintTypeId = blueprintType.TypeID
This identifies the most recent records for all the blueprintTypeids in the subquery. It then joins in the one that matches.
