-- Why is the left table in a LEFT JOIN limited by the where clause on the right table?eg
DECLARE @LeftTable TABLE (LeftID INT NOT NULL IDENTITY(1, 1), LeftValue INT NULL)
INSERT @LeftTable (LeftValue)
VALUES (111)
INSERT @LeftTable (LeftValue)
VALUES (222)
[code]....
Anyone know why using
SELECT *
FROM a LEFT OUTER JOIN b
ON a.id = b.id
instead of
SELECT *
FROM a LEFT JOIN b
ON a.id = b.id
generates a different execution plan?
My query is more complex, but when I change "LEFT OUTER JOIN" to "LEFT JOIN" I get a different execution plan, which is absolutely baffling me! Especially considering everything I know and was able to research essentially said the "OUTER" is implied in "LEFT JOIN".
Any enlightenment is very appreciated.
Thanks
I am using stored procedure to load gridview but problem is that i am not getting all rows from first table[ Subject] on applying conditions on second table[ Faculty_Subject table] ,as you can see below if i apply condition :-
Faculty_Subject.Class_Id=@Class_Id
Then i don't get all subjects from subject table, how this can be achieved.
Sql Code:-
GO
ALTER Proc [dbo].[SP_Get_Subjects_Faculty_Details]
@Class_Id int
AS BEGIN
[code] ....
Now I have a table with the table design as following :
table cst_EmpProfile
intEmpId nvcEmpName nvcEmpAddress intEmployeeType bitActiv
1 Peter Null Null true
2 Juli 1, xxxx 2 true
3 Sam Null Null False
table cst_EmpType
intEmpType nvcEmployeeType
1 Free Enginner
2 Manager
3 Operator
To join the table but MUST follow the condition as bitActiv = TRUE:
select emp.nvcEmpName, emp.nvcEmpAddress, ety. nvcEmployeeType from cst_EmpProfile emp left join cst_EmpType on emp.intEmployeeTypee = ety.intEmpType and emp.bitActiv = 1.
But, the sql statement doesnt output the my expected result.
Because the data row return must be 1st and 2nd row as it bitActiv = true.
So, how's I going achieve what i want. tq.
I was writing a query using both left outer join and inner join. And the query was ....
SELECT
S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT
S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
LEFT OUTER JOIN Production.Categories AS C
ON C.categoryid = P.categoryid)
ON
S.supplierid = P.supplierid
WHERE
S.country = N'Japan';
The result i got was same,i.e
supplier country productid productname unitprice categorynameSupplier QOVFD Japan 9 Product AOZBW 97.00 Meat/PoultrySupplier QOVFD Japan 10 Product YHXGE 31.00 SeafoodSupplier QOVFD Japan 74 Product BKAZJ 10.00 ProduceSupplier QWUSF Japan 13 Product POXFU 6.00 SeafoodSupplier QWUSF Japan 14 Product PWCJB 23.25 ProduceSupplier QWUSF Japan 15 Product KSZOI 15.50 CondimentsSupplier XYZ Japan NULL NULL NULL NULLSupplier XYZ Japan NULL NULL NULL NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.
I have a problem when I Left Join this table:

How can I join that table to make the result just one record?
Can anybody help me?
I have an problem with the order of the results after a join.
My first query works fine and the order of field Name ist correct.
Select *
FROM
(SELECT * FROM
dtree A1
WHERE
A1.Subtype=31356
AND
A1.DataID IN
(select DataID from dtreeancestors where AncestorID=9940974)) t
When I do a join the order of the left table changes
Select *
FROM
(SELECT * FROM
dtree A1
WHERE
A1.Subtype=31356
AND
A1.DataID IN
(select DataID from dtreeancestors where AncestorID=9940974)) t, llattrdata A4
WHERE
t.DataID = A4.ID
How can I do a join and keep the order of the left table?
I have a query that include a single LEFT JOIN. I would like to be able to select at most 1 row of the second table (providing that the JOIN represents a one to many relationship).
Does anyone knows how to do that?
Thanks in advance,

I have tables A and B.
Table A has data, but B may have or not.
I have to get -- at least! -- the A table data.
It works when I dont have the where clause:
select * from A left outer join B on A.IDUser = B.IDUser
But it doesn't when I try to use the WHERE clause:
select * from A left outer join B on A.IDUser = B.IDUser
where A.IDUser = 2
Hello,
I have two tables:
tasks
idint
useridint
otherstuff int
sample rows:
1,11,2
2,11,2
times
idint
taskidint
startweekdatetime
statusint
sample rows:
1,1,'04/28/2008',1
2,1,'04/28/2008',1
2,2,'04/28/2008',1
I want to retrieve:
ALL [tasks] with [times].[status] for a specific user for a given week, whether rows exist in [times] or not.
Here's my query:
select tasks.id, times.status
from tasks
LEFT OUTER JOIN times ON tasks.id = times.taskid
where upt.userid=11 AND times.startweek='05/05/2008'
That just doesn't return any the records though for the 05/05/2008 date. Its as though I want to join with a WHERE clause on the [times] table. What can I do?
Thanks in advance,
Brian

View 3 Replies View RelatedI have a query that has a left join with a large partitioned table. The partitioned table has 10s of millions of records, and each partition has about 100,000 records.
The left join is part of an insert that gets a column from the partitioned table, if the column exists. The query contains the partition ID and all other joined columns are part of a non-clustered index.
Through the profiler, I found that there were millions of reads and the execution plan was giving me a table scan on the partitioned table.
I changed the query to do the insert followed by an update with inner join. That did the trick, but it worries me that SQL Server 2014 behaves differently from 2012 or 2008R2, which can make upgrading very time consuming.
I am still new to SQL and I am having trouble obtaining the results I need from a query. I have worked on this command for some time and searched the internet but cannot seem to still get it correct.
I have a table called Patient. It's primary key is pat_id.
I have a second table called Coverage. It has no primary key. The foreign keys are pat_id, coverage_plan_id, and hosp_status.
I have a third table called Coverage_History. It has a primary key consisting of pat_id, hosp_status, copay_priority, and effective_from.
I want to get the pat_id and all the coverage information that is current. The coverage table contains specific insurance policy information. The coverage_history table will indicate the effective dates for the coverage. So the tables could contain something like this:
Patient (pat_id and lname)
P123 Monto
P124 Minto
P125 Dento
P126 Donto
Coverage (pat_id, coverage_plan_id, hosp_status, policy_num)

P124 MED1 OP C90009

P124 MED1 OP C90009
P125 ARP OP G190

P125 OP 1 20150801 ARP NULL
P126 OP 1 20150801 BCB 20160101
select p.pat_id, p.lname, ch.coverage_plan_id, ch.hosp_status, ch.effective_from, ch.effective_to, ch.copay_priority,
from patient p
left join
( coverage_history ch left join coverage c on ch.coverage_plan_id = c.coverage_plan_id and ch.patient_id = c.patient_id and
(ch.effective_to is NULL or ch.effective_to >= getdate()
)
) on ch.patient_id = p.patient_id
where ( ch.effective_to is NULL or ch.effective_to >= getdate() )

P123 Monto ACT4 OP 20150102 NULL 2
P124 Minto MED1 OP 20150501 NULL 1

Looking to improve performance of the following code.
It basically generates future days for each dog. So there is a dog table and a day table with every day.
These 2 table cross join and then fill in missing rows. As time moves i will fill in further future dates but will need the initial insert to be a reasonable query.
All columns are covered by index's but the queries at the end take quite a long time. I would hope for index scan to just point out the missing rows especially on the final query.
How to make the last query as fast as possible.

I am trying to tweak some code which is used to display the newest comments left on photos created by my members.
The existing code is this:
SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC
So the latest comment left was for photo #210879 from user "Cla" (redacted user names). The 2nd newest comment would be for photo #211072 from a member named "mo". pdate is a date field
However for the script I have coded I don't want all of the photo comments to show up. This is because I use access levels based on the type of location (higher levels mean more restricted galleries). I check the access levels as I go through the recordsets.
I use this method to get the top 15 comments:
SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC
Now I have to use two other tables to determine the access level. Since PHOTOCOMMENTS is just a list of photo #'s and the people who left comments for those photos, I need to:
a) determine what location the photo is from and
b) determine the access level of that location
I use: select creator,access from locations where id=(select dir from photos where id="&pnumber&")"
This is a two step process as you can see. The first part is:
select dir from photos where id=(pnumber)
ID is the same value as pnumber seen in PHOTOCOMMENTS. That is to say PHOTOS.ID = PHOTOCOMMENTS.PNUMBER
If I haven't confused you yet, the executed code for the first example would be:
select dir from photos where id=210879
which would get me a value for DIR. DIR is the location number which would be:
select creator,access from locations where id=(dir value)
Just to simplify it a bit....
There are three tables (shown below)
PHOTOCOMMENTS
PHOTOS
LOCATIONS
I need to: SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC (first table shown)
but then also
select creator,access from locations (The last table shown)
where id=(select dir from photos where id="&pnumber&")"
So the first table PHOTOCOMMENTS has to also join PHOTOS table where PHOTOS.DIR = PHOTOCOMMENTS.PNUMBER in order to get the value of "DIR" and then DIR is joined to the LOCATIONS tables where PHOTOS.DIR = LOCATIONS.ID
Here is the actual code, which I am trying to make into a single SQL command
strSQL = "SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC"
set ors = oconn.Execute(strSQL)
tl = 0
do until ors.eof or tl > 15
' until we have 15 results because not every recordset will be of the proper security level
[Code] ....
Bonus points if you can also get it to select from LOCATIONS only WHERE userlevel >= 2

Is there any difference between left join and left outer join in sql server 2000?please reply with example if any?
Thanks in advance
Hi,
Whats the diference between a left join and a left outer Join
Hi there,
I'm using the SQL 2005 Express Edition and i would like to know if there's any way to change the Table alignment to Right To Left.
Please if you can, send me your reply to my E-Mail address: zaki666@zahav.net.il

I have a table PLACE with a character column CODE
[Code] [nchar](4) NULL
I need to left pad the column with 0 if it is less than 4 characters long and extract the first 2 characters on the left into a new column COUNTY_CODE.
How can I do that in transact SQL?
I tried:
SELECT RIGHT(RTRIM('0000'+ISNULL([Code],'')),4)
FROM [Place]
WHERE [Place Code]='B' and [Code]='627'
And I got 0627. And how do I extract the first 2 characters?
I have a table that lists states that I need to see order info from. I am attempting to create a SQL query that displays the production data for those states. So if the state is in my saleState table I want it to show in my query result even if there were 0 sales to that state. Below is the syntax I am trying, but if the count is 0, it is not returning the sales state it is omitting it.
Code:
Select a.state, COUNT(b.recordID)
From saleState a left outer join tblSales b
On a.state = b.state
And b.orderDate between '01/01/2012' AND '12/31/2012'
Need to point out the error in my query syntax?
I have two xml source and i need only left restricted data.
how can i perform left restricted join?
Until today, I was always under the impression that left vs. right was determined by which side of the comparison operator the table was located.
In other words:
LEFT JOIN LeftTable.ID = RightTable.ID
would pull all the records from LeftTable and those that matched from from RightTable and that:
RIGHT JOIN RightTable.ID = LeftTable.ID
would pull exactly the same result set but I was wrong. So, if it is not the table position in relation to the comparison operator, is it simply that the tables listed first in the FROM clause aren the ones "Left" of those subsequently entered?
I'm trying to write a 3 table query using two LEFT JOINs. Originally, I only had one LEFT JOIN and prior to the addition of the the third table (parts) this query worked. Now it doesn't. I think it has to do with my GROUP BY.

Good afternoon,
I'm trying to use a parameterin a way that RS seems to think is unnatural, and I'm wondering about a work around...
Normally I can use parameters like so:
select *
from foo
where fooValue > @myParameter
What I'd like to do instead is use a constant on the right of the predicate, and a parameter to define the column to measure against, like so:
select *
from foo
where @myParameter > 10
Or
select *
from foo
where @myParameter is not null
Any assist with this is greatly appreciated...
Thanks,
Brian
I'm trying to join 2 tables. I thought I was getting the correct results but it turns out I'm not.
My Query:
SELECT IVINVA, IVORDN, IVCSLN, IVRESR, IVCITM, CONVERT(varchar(12),CAST(IVIAMT as money),1) AS ExtPrice, CONVERT(varchar(12),CAST(IVPIVC as money),1) AS DistPrice, IVCSUM, IVQYCS, IVDESC, OIRESR, OIDPCT, CONVERT(varchar(12),CAST(IVPIVC - (OIDPCT / 100 * IVPIVC) as money),1) AS NetPrice FROM INVDET1_TBL LEFT JOIN ORDDIS_TBL ON ORDDIS_TBL.OIORDN = INVDET1_TBL.IVORDN AND ORDDIS_TBL.OIRESR = INVDET1_TBL.IVRESR WHERE IVORDN = '0859919' AND IVINVA = '00324024'
Basically, my problem lies in the seonc condition of the LEFT JOIN. I needed to set the two tables equal my item number, because in some situations I need that logic to get the correct result. It most other cases, that item column in the ORDDIS_TBL is NULL, thus giving me the wrong results. In that case, I would want the JOIN to only be ORDDIS_TBL.OIORDN = INVDET1_TBL.IVORDN, and not include the second part. Is there a way I can condition this with an If statement, If ORDDIS_TBL.OIRESR is Null then do this join, if not, then do this? I'm confused how to get the proper result here.
