Keep Order Of Left Table After Join

May 20, 2014

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?

Left Join Vs Left Outer Join Syntax Generates Different Execution Plans

Apr 16, 2008



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

Transact SQL :: Difference Between Inner Join And Left Outer Join In Multi-table Joins?

Oct 8, 2015

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.

Left Join Table

Jul 18, 2006

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.

SQL Server 2014 :: Left Join With A Large Partitioned Table?

Aug 3, 2015

I 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.

Transact SQL :: Left Join To Get Info From A Table With Foreign Keys

Sep 13, 2015

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)
P123     MED1   OP   A1499
P123     ACT4   OP   H39B 
P124     MED1   OP   C90009
P124     RAC    OP   99KKKK
P124     RAC    OP   99KKKK
P124     MED1   OP   C90009
P125     ARP    OP   G190
P126     BCB    OP   H88

Coverage_History (pat_id, hosp_status, copay_priority, effective_from, coverage_plan_id, effective_to)
P123   OP   1   20150102  MED1    NULL
P123   OP   2   20150102  ACT4    NULL
P124   OP   1   20150203  RAC     20150430
P124   OP   2   20150203  MED1    20150430
P124   OP   1   20150501  MED1    NULL
P124   OP   2   20150501  RAC     NULL
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() )
   
So I want to see:

P123  Monto  MED1  OP   20150102    NULL       1
P123  Monto  ACT4  OP   20150102    NULL       2
P124  Minto  MED1  OP   20150501    NULL       1
P124  Minto  RAC   OP   20150501    NULL       2
P125  Dento  ARP   OP   20150801    NULL       1
P126  Donto  BCB   OP   20150801    20160101    1

SQL Server 2014 :: 2 Tables Combined Left Join To Primary Key Of A 3 Third Table

Sep 1, 2014

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.

IF OBJECT_ID('dbo.[AllDates]', 'U') IS NOT NULL
DROP TABLE dbo.[AllDates]
CREATE TABLE dbo.[AllDates] (
[Date] date not null PRIMARY KEY
)
;WITH Dates AS

Three Table Join - Display Newest Comments Left On Photos Created By Members

Jul 6, 2014

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

Incorrect Order Result Set When Join Table

Mar 24, 2002

Hi all,
I faced a problem, I have two tables - part and partmaster
part : part_no, part_qty (no key)
partmaster : part_no, part_description (primary key : part_no )

I want to select table part.* and partmaster.part_description.

(run on mssql 2k)
select a.*, b.part_description
from part a, partmaster b where a.part_no *= b.part_no

I want to and expect to have the result order like table "part". However, after the join, the order is different. I try to run it on mssql 7.0, the order is ok.

Then I modify and run the statement select a.* from part a, partmaster b where a.part_no *= b.part_no on 2k again. The result order is ok.

can anyone tell me the reason?

Now I try to fix this problem is adding a sequence field "part_seq" into table "part" and run the statement by adding a order by part_seq.
It does work!

Regards,
Simon

How To Join 3 Tables Using Left Or Right Join Keyword?

Aug 17, 2007

Hi guys,

I'll appreciate any help with the following problem:

I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.

1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02

2. Master table TBCODE contain 5 records:

rcd 1. C1
rcd 2. C2
rcd 3. C3
rcd 4. C4
rcd 5. C5

3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR

rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR



I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.

Right Join method:


SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE

RIGHT JOIN TBLOC C ON A.LOC = C.LOC

GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE



When I use Non-ASNI method it work:



SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C

WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC

GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE

Result:

LOC CODE ITEM
-----------------------------
S01 C1 NULL
S01 C2 NULL
S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL


Please Help.

Thanks.

SQL LEFT JOIN Help

Jan 26, 2007

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.

How Many 'LEFT JOIN' Is Too Many?

Feb 26, 2004

Any one know any facts and figures about maximum Left Joins allowed (or recommended) in one query?

I am running a MS SQL 2000 my database is full of relational data and most of my foreign keys (INT data type) are a Clustered Indexed, Usually I will only be pulling one record from collection of about a dozen tables, but the Database is expected to grow fast and become big.

Right now I have a Stored Proc that has eight(8) LEFT JOINs in it. My worry is that this query will kill me as the database approaches 50,000 records.

Left Join

Mar 6, 2007

Hi all. My query works fine, it generates reports but not my expected result.

select d.fullname, p.nickname, p.birthdate, p.birthplace,
p.gender, p.civilstatus, p.religion, p.nationality, p. weight, p.height,
p.haircolor, p.eyecolor, p.complexion, p.bodybuilt, p.picture, p.dialectspoken,
d.mobilephone, d.prprovince,[Age] = dbo.F_AGE_IN_YEARS( birthdate, getdate() ),
c.name, c.address, c.telno, c.email, c.occupation, ed.year1, ed.year2, ed.degree, sch.schname
from hremployees as e
inner join psdatacenter as d on e.empdcno = d.dcno
inner join pspersonaldata as p on e.empdcno = p.dcno
left join hrappempcharrefs as c on e.empdcno = c.empdcno
left join hrappempeducs as ed on e.empdcno = ed.empdcno
left join hrsetschools as sch on ed.schoolcode = sch.schcode

the above query gives a 77 records

if i ran "select * from hremployees" generates 60 records

i think the error is in the left joining.
hrappempcharrefs, hrappempeducs and hrsetschools must be left joined to hremployees.

thanks

Left Outer Join-please Help!

Jan 7, 2002

Hello!
I need to write a query using left outer join and I'm having trouble with it.
I have 2 tables:customer and cust_info.
I want to pull all records from customer table and cust_info table even if there is no related data in cust_info table.
But I need one condition in this query:only records from customer table where cus_type in ("A","B","C").
I don't need all other types ("D","E").

So my query looks like this:

select customer.cus_name,customer.cus_address,customer.cu s_type,cus_info.status
from customer
left outer join cus_info ON customer.sxdat_pk = cus_info.sxdat_pk
and cus_type in ("A","B","C")
AND cus_info.cus_table = 'CUSTOMER'

The result should be like this:

cus_name cus_address cus_type status
Amoco 457 bent A new
Bingo 47 lone oak C NULL
Sears 1020 Magic dr. B exist


But my query pulls records for customers with type "D" and "E" that I'm trying to exclude from result.


Please help.
Thanks,
lena

LEFT JOIN Problem

Apr 18, 2008

Hello everybody!!!

I have to left join 2 tables. The first consists of columns:id, description, descr_num.
The second table: id, descr_num, value.

I need to extract description from table1 where descr_num is in the range , say, 1-10.

LEFT JOIN

extract value from table2 ,descr_num should be in the same range. in table2 some values from (1,10) and desc_num could be not present.
BUT i want this left join to be limited as i said.

Is there any solution to this prob. without creating temp tables. Or actually can i do such a join?
Thank you

Stumped - LEFT JOIN

Jan 10, 2007

Hi, I'm getting the error Syntax error (missing operator) in query expression 'dbPWork.id = dbPWorkWord.work_id LEFT JOIN words ON dbPWorkWord.word_id = words.id'." on the query below. Everything looks in place to me. Do you see anything that shouldn't work?

Query:

Code:

Code:

SELECT DISTINCT dbPWork.id, description_e as description, w_id , dateStart, dateEnd FROM dbPWork
LEFT JOIN dbPWorkW ON dbWork.id = dbPWorkW.work_id
LEFT JOIN words ON dbPWorkW.word_id = words.id



Everything works fine until I add the second LEFT JOIN statement. Any ideas? I'm stumped.

I have a left join that doesn't suit my request.

select * from A
left join B

The problem is that for a specific record in A we can find 1 or more entries in B. What I want is to return only the 1st entry found on B.
