I am trying to find subdepartments where they link by description if one is their it should return the id of the one in the table I am using the following query.
SELECT DISTINCT Subdeptcode
,SubDepartment
FROM SkechersPricat
WHERE SubDepartment IN ( SELECT DISTINCT description
FROM SubDept )
AND processed = false
AND SubDeptCode = 0
I need To be able to return the subdeptcode from the sub dept table if one exists if one Doesnt exist create it so I need a query that can account for both condision im using vb.net
Main File looks like the following
Sub Debt table above
For starters lets look at your query
SELECT DISTINCT Subdeptcode
,SubDepartment
FROM SkechersPricat
WHERE SubDepartment IN ( SELECT DISTINCT description
FROM SubDept )
AND processed = false
AND SubDeptCode = 0
you are trying to say that SubDepartment column needs to be in one of the values of description from SubDept table. Unless your SubDepartment matches description exactly it will not return anything.
Proper syntax for your query would be using LEFT OUTER JOIN. By using LEFT OUTER JOIN you are saying to get all results from your left table and only records that match in your right table. Thus you still get all the records from main table even if there is no match in SubDept table.
Your query will be like this
SELECT DISTINCT s.Subdeptcode
,s.SubDepartment
FROM SkechersPricat s
LEFT OUTER JOIN SubDept sd
ON s.SubDepartment = sd.description
WHERE s.processed = false
AND s.SubDeptCode = 0
What I do see in your screenshot that GeminDepartmentID corresponds to DeptCode from SubDept table. I think you are not joining on correct value.

To begin with, I have a table in my db that is fed with SalesForce info. When I run this example query it returns 2 rows:
select * from SalesForce_INT_Account__c where ID_SAP_BAYER__c = '3783513'
When I run this next query on the same table I obtain one of the rows, which is what I need:
SELECT MAX(ID_SAP_BAYER__c) FROM SalesForce_INT_Account__c where ID_SAP_BAYER__c = '3783513' GROUP BY ID_SAP_BAYER__c
Now, I have another table (PedidosEspecialesZarateCabeceras) which has a field (NroClienteDireccionEntrega) that I can match with the field I've been using in the SalesForce table (ID_SAP_BAYER__c). This table has a key that consists of just 1 field (NroPedido).
What I need to do is join these 2 tables to obtain a row from PedidosEspecialesZarateCabeceras with additional fields coming from the SalesForce table, and in case those additional fields are not available, they should come as NULL values, so for that im using a LEFT OUTER JOIN.
The problem is, since I have to match NroClienteDireccionEntrega and ID_SAP_BAYER__c and there's 2 rows in the salesforce table with the same ID_SAP_BAYER__c, my query returns 2 duplicate rows from PedidosEspecialesZarateCabeceras (They both have the same NroPedido).
This is an example query that returns duplicates:
SELECT
cab.CUIT AS CUIT,
convert(nvarchar(4000), cab.NroPedido) AS NroPedido,
sales.BillingCity__c as Localidad,
sales.BillingState__c as IdProvincia,
sales.BillingState__c_Desc as Provincia,
sales.BillingStreet__c as Calle,
sales.Billing_Department__c as Distrito,
sales.Name as RazonSocial,
cab.NroCliente as ClienteId
FROM PedidosEspecialesZarateCabeceras AS cab WITH (NOLOCK)
LEFT OUTER JOIN
SalesForce_INT_Account__c AS sales WITH (NOLOCK) ON
cab.NroClienteDireccionEntrega = sales.ID_SAP_BAYER__c
and sales.ID_SAP_BAYER__c in
( SELECT MAX(ID_SAP_BAYER__c)
FROM SalesForce_INT_Account__c
GROUP BY ID_SAP_BAYER__c
)
WHERE cab.NroPedido ='5320'
Even though the join has MAX and Group By, this returns 2 duplicate rows with different SalesForce information (Because of the 2 salesforce rows with the same ID_SAP_BAYER__c), which should not be possible.
What I need is for the left outer join in my query to pick only ONE of the salesforce rows to prevent duplication like its happening right now. For some reason the select max with the group by is not working.
Maybe I should try to join this tables in a different way, can anyone give me some other ideas on how to join the two tables to return just 1 row? It doesnt matter if the SalesForce row that gets picked out of the 2 isn't the correct one, I just need it to pick one of them.
Your IN clause is not actually doing anything, since...
SELECT MAX(ID_SAP_BAYER__c)
FROM SalesForce_INT_Account__c
GROUP BY ID_SAP_BAYER__c
... returns all possible IDSAP_BAYER__c values. (The GROUP BY says you want to return one row per unique ID_SAP_BAYER__c and then, since your MAX is operating on exactly one unique value per group, you simply return that value.)
You will want to change your query to operate on a value that is actually different between the two rows you are trying to differentiate (probably the MAX(ID) for the relevant ID_SAP_BAYER__c). Plus, you will want to link that inner query to your outer query.
You could probably do something like:
...
LEFT OUTER JOIN
SalesForce_INT_Account__c sales
ON cab.NroClienteDireccionEntrega = sales.ID_SAP_BAYER__c
and sales.ID in
(
SELECT MAX(ID)
FROM SalesForce_INT_Account__c sales2
WHERE sales2.ID_SAP_BAYER__c = cab.NroClienteDireccionEntrega
)
WHERE cab.NroPedido ='5320'
By using sales.ID in ... SELECT MAX(ID) ... instead of sales.ID_SAP_BAYER__c in ... SELECT MAX(ID_SAP_BAYER__c) ... this ensures you only match one of the two rows for that ID_SAP_BAYER__c. The WHERE sales2.ID_SAP_BAYER__c = cab.NroClienteDireccionEntrega condition links the inner query to the outer query.
There are multiple ways of doing the above, especially if you don't care which of the relevant rows you match on. You can use the above as a starting point and make it match your preferred style.
An alternative might be to use OUTER APPLY with TOP 1. Something like:
SELECT
...
FROM PedidosEspecialesZarateCabeceras AS cab
OUTER APPLY(
SELECT TOP 1 *
FROM SalesForce_INT_Account__c s1
WHERE cab.NroClienteDireccionEntrega = s1.ID_SAP_BAYER__c
) sales
WHERE cab.NroPedido ='5320'
Without an ORDER BY the match that TOP 1 chooses will be arbitrary, but I think that's what you want anyway. (If not, you could add an ORDER BY).
New to SQL but I want to be able to optimize my query by bringing just the right amount of data. I am doing a left join on CS Rep Name and WE, which are two columns present in both tables. I find that if I don't bring in CS Rep Name and WE in the TECDR table, the query would error. Is there a workaround to this? Since it is a left join, I don't need redundant data.
SELECT *
FROM Tish_Email_CSAT_Dump AS TECD
LEFT JOIN (SELECT CS_Rep_Name,
Team_Leader,
Operations_Manager,
Tenure,
WE,
FileName
FROM Tish_Email_CSAT_Dump_Roster) AS TECDR
ON TECD.CS_Rep_Name = TECDR.CS_Rep_Name
AND TECD.WE = TECDR.WE
When you embed a SELECT inside a query in place of a table, the result of a select (projection) behave like a table visible only inside the query.
In your case, the join is the same as if there were a table called TECDR with the columns that you select. Hence, if you leave out some columns of Tish_Email_CSAT_Dump_Roster from your SELECT, these columns would not be available for joining or selection.
However, in your case this is unnecessary: all you need to do is joining to the underlying table, like this:
SELECT
TECD.*
, TECDR.Team_Leader
, TECDR.Operations_Manager
, TECDR.Tenure
, TECDR.FileName
FROM Tish_Email_CSAT_Dump AS TECD
LEFT JOIN Tish_Email_CSAT_Dump_Roster AS TECDR
ON TECD.CS_Rep_Name = TECDR.CS_Rep_Name AND TECD.WE = TECDR.WE
select
<place the columns you want here>
from
Tish_Email_CSAT_Dump as TECD
Left join Tish_Email_CSAT_Dump_Roster as TECDR
On TECD.CS_Rep_Name = TECDR.CS_Rep_Name and TECD.WE = TECDR.WE
Hope the following helps or else please share the query that errors:
select TECD.Column1, TECD.Column2, TECDR.Column1, TECDR.Column2
from Tish_Email_CSAT_Dump as TECD
Left join Tish_Email_CSAT_Dump_Roster as TECDR
On TECD.CS_Rep_Name = TECDR.CS_Rep_Name and TECD.WE = TECDR.WE
I've got a table of products and a table of widgets.
A product is built from a number of widgets and I've got a linking table which shows which widgets are linked to which products.
Widgets can be marked as expired, which means they are not eligible to be added to any new products.
Schema and sample data in the following sqlFiddle -
I want a query that shows all the eligible widgets for a particular product given the following rules:
A widget should not be shown if it is marked as expired.
As an exception to the above rule - If a widget is marked as expired, but is already linked to a product, then it should be shown.
If a widget has already been linked to the product, it should be marked as 'selected'
I've got the following query which works, and satisfies all the above rules:
select
data.WidgetName,
data.expired,
case
when data.ID in (select data_id from Widget_link where productId = 1)
then 1
else 0
end as selected
from Widget_data data
left outer join Widget_link link
on data.ID = link.data_id and data.expired = 1
where (data.expired = 0 or (data.expired = 1 and link.productId = 1))
I'd like to find a way to refactor the sub-query within the select part of the query to some kind of join. I'm trying to create a view which I can filter using just a where clause, rather than having the productId in two places. Is this possible?
On simplification your query can solely be evaluated based on JOIN like below, and there is no need for inner query at all.
select data.WidgetName,
case when link.id is not null then 1 else 0 end as selected
from Widget_data data
left outer join Widget_link link
on data.ID = link.data_id and link.productId = 1
where data.expired=0 or link.id is not null

You can use SQL CTE (Common Table Expression) to cover the results from a SELECT list, and use in a single SQL statement
You can even create SQL statements with multiple CTE's in your code
What I suggest is can be summarized visually as follows
WITH cte AS (
SELECT ..... FROM .....
),
other_cte AS (
SELECT ..... FROM .....
)
SELECT *
FROM cte
INNER JOIN other_cte ON...
My code is such:
SELECT COUNT(*)
FROM earned_dollars a
LEFT JOIN product_reference b ON a.product_code = b.product_code
WHERE a.activity_year = '2015'
I'm trying to match two tables based on their product codes. I would expect the same number of results back from this as total records in table a (with a year of 2015). But for some reason I'm getting close to 3 million.
Table a has about 40,000,000 records and table b has 2000. When I run this statement without the join I get 2,500,000 results, so I would expect this even with the left join, but somehow I'm getting 300,000,000. Any ideas? I even refered to the diagram in this post.
it means either your left join is using only part of foreign key, which causes row multiplication, or there are simply duplicate rows in the joined table.
use COUNT(DISTINCT a.product_code)
What is the question are are trying to answer with the tsql?
instead of select count(*) try select a.product_code, b.product_code. That will show you which records match and which don't.
Should also add a where b.product_code is not null. That should exclude the records that don't match.
b is the parent table and a is the child table? try a right join instead.
Or use the table's unique identifier, i.e.
SELECT COUNT(a.earned_dollars_id)
Not sure what your datamodel looks like and how it is structured, but i'm guessing you only care about earned_dollars?
SELECT COUNT(*)
FROM earned_dollars a
WHERE a.activity_year = '2015'
and exists (select 1 from product_reference b ON a.product_code = b.product_code)
I am having some problem when trying to perform a SQLite query to get the records which does not exist from another table. Basically I have two database tables:
My exercise table stored all the exercises available whereas the bookedExercise table store the exercises booked by each users. What I am trying to do is, for example if the exercise does exist in the bookedExercise, it should be filtered out.
Here is the SQLite query which I used:
SELECT exercise.exerciseID, exercise.exerciseType, exercise.amout FROM exercise LEFT JOIN bookedExercise WHERE exercise.exerciseID = bookedExercise.exerciseID AND bookedExercise.exerciseID IS NULL
However, it returned me empty records. Any ideas?
Thanks in advance.
If you're fine with not using joins you could use
SELECT * FROM exercise WHERE exerciseID not in (SELECT exerciseID FROM bookedExercise)
When you are using LEFT JOIN, you must put the join condition into the ON clause:
SELECT exercise.exerciseID,
exercise.exerciseType,
exercise.amout
FROM exercise /* !! */
LEFT JOIN bookedExercise ON exercise.exerciseID = bookedExercise.exerciseID
WHERE bookedExercise.exerciseID IS NULL
Your SQL looked okay... I think the problem might be you have a datatype mismatch. You have exercise ID as an integer in one table and text in another.
Also, if you have huge data volumes, you may want to consider an anti-join:
select
e.*
from
exercise e
where not exists (
select 1
from bookedExercise be
where
e.excerciseId = be.exerciseID
)
-- edit --
On second glance, your SQL was not okay. You had your join condition in the where clause. This little change would fix your existing SQL:
SELECT exercise.excerciseId , exercise.exerciseType , exercise.amout
FROM exercise LEFT JOIN bookedExercise on
exercise.excerciseId = bookedExercise.exerciseID
WHERE bookedExercise.exerciseID IS NULL
