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.

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

Transact SQL :: Left Join Returns Too Many Rows Vertically

Jun 18, 2015

I have a query that based 2 tables. I wrote a query with a left join on the base table but the result set returns multiple rows for each occurrence in the second table because of the left join. I want but to return all records from on table A and only matching records from table B which id but I would wan tit to keep return them vertically as the because it make it difficult to read when put in a spreadsheet. It want it to return the values horizontally so the rows are not increasing for each occurrence on table b.

Condition In Left Outer Join

Jan 22, 2008

Hi,
I want to get join of two tables A and B in such a way that all the Data from A for a particular Date should be extracted and then from table B Reqired column should selected against that data (it can be null). But if i use the following query:
1) Select A.*,B.Reqired from A Left Outer Join B on A.Same=B.Same Where A.Date = '1/22/2008'
it first joins the Table A and B (A contains millions of records) which takes a lot of time and then where is applied which takes a lot of time.
And if I use the following query:
2)Select A.*,B.Reqired from A Left Outer Join B on A.Same=B.Same AND A.Date = '1/22/2008'
in this case A.Date = '1/22/2008' has no effect and all the data from the table A comes.
I have also tried first making the temp table for A.Date = '1/22/2008' and the joining with B but its cost is same as 1.
For this purpose Oracle allows the use of (+) operator like:
3)Select A.*,B.Reqired from A,B
Where A.Same=B.Same(+) AND A.Date = '1/22/2008' which means all data from A for '1/22/2008' Plus B.Required against it whether its null or not.
Please let me know if there is a way around in MS SQL SERVER 2005.
Thanx.

Some Question About Left Join On Condition?

Oct 31, 2007

Left join on condition has no effect in the left table itself?
I have two tables:
one named student

studentID studentName
-------------------------------------------------- --------------------------------------------------
1 Jom
2 Jim
3 Tom
4 Kate
5 LinDa
6 DaiAnna

The other is grade table

studentID subject grade
-------------------------------------------------- -------------------------------------------------- -----------
1 math 90
2 Chinese 90
1 Chinese 80
3 math 98
4 math 76

And I write two SQLs
1:
select students.studentName , grades.grade as math_grade
from student as students
left outer join grade as grades on students.studentID = grades.studentID and grades.subject = 'math'
2:
select students.studentName , grades.grade as math_grade
from grade as grades
left outer join student as students on students.studentID= grades.studentID and grades.subject = 'math'

After execute, the answer is
1:
studentName math_grade
-------------------------------------------------- -----------
Jom 90
Jim NULL
Tom 98
Kate 76
LinDa NULL
DaiAnna NULL

2:
studentName math_grade
-------------------------------------------------- -----------
Jom 90
NULL 90
NULL 80
Tom 98
Kate 76

The math_grade of the second answer is all the grade rows of the grade table. on grades.subjec='math' has no effect.
Why SQL will act it like this? I know it's not a bug. But I really wanna know the inside work.
Thanks in advance, with very appreciation.

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.

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 *

(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

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?

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.

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

T-SQL (SS2K8) :: Delete All Rows Satisfying Certain Condition From Table A And Related Records From B And C

Apr 14, 2015

I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.

What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.

Parent/Child Rows In Report, Nested Table, Textbox Value In Filter Condition

Mar 26, 2008

Hi All,

I am working on SQL server 2005 Reports.
I have one report, one dataset is assigned to it, and one table which displays it.
Now I come accros requirement that, the column value in the filter condition for the table is present in one textbox.

I can not use textbox i.e. reportItems in filter condition. Can someone suggest me how to use textbox value in filters?

I want to display parent/child records on report. I am not getting the proper solution.

The data is like this:

Sequence ItemCode IsParent

1 XYZ 0 'do not have child record

2 PQR 1 'have child records with sequence no 3

3 ASD 0

3 AFDGE 0

3 VDC 0

4 ASR 1 'have child records with sequence no 5
5 ASR 0

If IsParent = 1, that record has child records with sequence = parent sequenece + 1

I think u can understand the data I need to bind, and it is like:

XYZ

+ PQR

ASD

AFDGE

VDC

ASR

On + click we can do show/hide of child records.

I m not getting how to achive this in SQL server report. Can u give some hint?

Thanks in advance

Left Join Not Returning Rows

SELECT

[tblSectionContents].[linkID],

LEFT JOIN [tblSectionContents] ON [tblSectionContents].[sectionID] = [tblSections].[id]
LEFT JOIN [tblCopy] ON [tblSectionContents].[articleID] = [tblCopy].[id]
LEFT JOIN [tblFiles] ON [tblSectionContents].[fileID] = [tblFiles].[id]

WHERE [tblSections].[id]=2
ORDER BY
[tblSectionContents].[articleID],
[tblSectionContents].[fileID],
[tblSectionContents].[linkID]

If I pass it the ID of a section that has files or copy or [stuff in other tables] attached, then I get a result set that makes sense.

But if I pass it a section ID that doesn't reference any other content tables (ie: the section just has a title and a link URL), I don't get anything back.

Shouldn't it should still get me the fields from the row in tblSections that matches the ID I'm passing it?

How can I make it so that it does?

Thanks :)

Transact SQL :: How To Select A Single Record In A Left Join

Sep 16, 2015

My tables look like this:

Users //
table
UserID // pk
UserName // varchar
UserFamilyName // varchar
User_Friends //
table
FriendsID // pk
UserID // fk
FamilyName // varchar

MY query:

SELECT
U.UserFamilyName, F.FamilyName
FROM
Users U LEFT
JOIN User_Friends
F ON U.UserID =
F.UserID
WHERE
U.UserName = ‘JOHN’

How do I adjust my query to select just the very first record from Users_friends, I want only the top first one.And if there are no friends how can I return an empty string instead of Null.

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

Display All Rows In Left Outer Join (was Would Be So Grateful For Sql Help)

Jan 20, 2005

This is what I want my results to look like

invoice wbs1 wbs2 amount
8060 000-333 500 0
8060 000-333 100 0
8060 000-333 140 0
8060 000-333 150 4335
8060 000-333 160 0
8267 000-333 500 0
8267 000-333 100 20500
8267 000-333 140 547.50
8267 000-333 150 2000
8267 000-333 160 5000

This is what I have so far:

SELECT PR.WBS1, PR.WBS2, ledgerar.invoice, SUM(CASE WHEN ledgerar.transtype = 'in' AND ledgerar.period = '200405' THEN ledgerar.amount * - 1 END) AS amount
FROM PR LEFT OUTER JOIN
LedgerAR ON LedgerAR.WBS1 = PR.WBS1 AND LedgerAR.WBS2 = PR.WBS2 AND LedgerAR.WBS3 = PR.WBS3
WHERE (LedgerAR.wbs1 = '001-333') AND ledgerar.period = '200405'
GROUP BY pr.wbs1, pr.wbs2, ledgerar.invoice

the above query gives me the following results:

invoice wbs1 wbs2 amount
8060 000-333 100 0
8060 000-333 140 0
8060 000-333 160 4335
8267 000-333 100 1320
8267 000-333 140 20912.5
8267 000-333 150 8363
8267 000-333 160 2650

But I don't know how to get the query to display all of wbs2 whether it is null or not. So, for each invoice number there should be five records according to the wbs2 codes (500, 100, 140, 150, 160)

Does anyone know how to do this?

Thanks,
Laura

Left Outer Join Not Returning All/null Rows

Dec 31, 2007

Need some join help...

Table 1 - Modules:
ID | Name
1 | A
2 | B
3 | C

Table 2 - CompanyModules
ModuleID | CompanyID
1 | 1
2 | 1
3 | 1
1 | 2

I'd like to return the following result set:
CompanyModules.CompanyID | Modules.Name | Present
1 | A | True
1 | B | True
1 | C | True
2 | A | True
2 | B | False
2 | C | False

What would be the query for this? Thanks.

Edit: This is the query I have tried:

select CompanyModules.CompanyID, Modules.Name, count(Modules.ID) as Present from

CompanyModules RIGHT outer Join Modules on CompanyModules.ModuleID = Modules.ID

group By CompanyModules.CompanyID, Modules.Name

Order by CompanyID

However, it only returns a partial result set:

CompanyModules.CompanyID | Modules.Name | Present
1 | A | 1
1 | B | 1
1 | C | 1
2 | A | 1

Transact SQL :: Left Outer Join And Transaction Isolation Level

Nov 30, 2015

We have a service that inserts some rows into a parent table (P) and child table (C). This operation is atomic and performed within a transaction.

We also have a service that queries these tables such that rows are (should only be) returned from P where there are no children for that parent.

The SQL that performs this is simplified below:

SELECT P.SomeCol
FROM P
LEFT OUTER JOIN C ON P.PKofP_Value = C.PkofP_Value
WHERE
C.PkofPValue IS NULL
AND P.SomeOtherCol=0

Our expectation is that the query service should only return rows from P where there are no rows in C.

However, this seems not to be the case, and occasionally we find that rows from P are returned where there are matching rows in C.

We are sure that the process that inserts rows into P and C does so within a single transaction.

We have traced this with SQLTrace and can see the txn stag and committing and all operations using the same transactionid within the transaction.

We are running the default isolation level committed.

In SQLTrace we can see the query process start, the inserter process start and complete and then the query process continue (after presumably being blocked).

So how can the query process "miss" the child rows and return the parent from the above query?

Is it possible that, in this isolation level, the inserter process can block the query process such that when the inserter process commits and when the query process continues it does not see the child rows inserted because they were inserted in the table/index "behind" where the query process has already read - some kind of phantom phenomenon?

Transact SQL :: Condition Failed Rows Count

Jul 3, 2015

I am using SQL Server 2008.Each stock item will have default 4 document type (1, 5, 6, 7) and each will have 3 zone's (1, 2, 3) to qualify. Each zone will be updated to 1 for that document type if the item successfully pass through it. If all zone are NULL means no transaction. How to retrieve only the failed rows which means not all zone are 1 or NULL.In the image GJ-00064 has one row failed. So how to get the count of failed rows for each item

Expected result:

Uniid <-> Stockcode <-> FailedRows
1670 <-> GJ-00064 <-> 1

Transact SQL :: Using Join With Part Of A Table

Jul 14, 2015

I have a table like this :

reg.no | description | start_date | end_date | load_date

I want to join this table with itself on reg. no. But not all the rows in table must be joined.

But for example, rows with load_date 01-07-2015 to be joined with rows with load_date 02-07-2015. And the rest of the rows should not used in join (for example, rows having other load_dates)

Is this possible ? and how?

Transact SQL :: Get Min Date Row From Join Table

Sep 10, 2015

I have the following 2 tables:

Location:

Policy:

1 Location can be attached to many policies.

I need to create a query to get 1 row per location and get the minimum PolicyBookingDt and RowUpdateDt from the policy table. All the attributes from the Location table should also be from the Policy that has the minimum PolicyBookingDt.

So from the above example, i need to get the following:

Getting a little confused on how to create the syntax for this.

INNER JOIN Between A CLR-TVF And A Table Returns No Rows

Feb 24, 2007

I have the following query:

select sq.*, p.numero, p.nombre
from paf p right outer join dbo.GetListOfSquaresForShippingLot(@lot) sq on sq.number = p.numero and sq.version = p.numero

The @lot parameter is declared at the top ( declare @lot int; set @lot = 1; ). GetListOfSquaresForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.

If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.

I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.

What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.

PLEASE HELP!!!!

Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:

CREATE FUNCTION [dbo].[GetTabListOfSquaresForShippingLot]
(
@ShippingLot int
)
RETURNS
@result TABLE
(
Number int, Version int, Position smallint,
SubModel smallint, Quantity smallint,
SquareId nvarchar(5),
ParentSquareId nvarchar(5),
IsSash smallint,
IsGlazingBead smallint,
Width float,
Height float,
GlassNumber smallint,
GlassWidth float,
GlassHeight float
)
AS
BEGIN
INSERT INTO @result
SELECT *
FROM dbo.GetListOfSquaresForShippingLot(@ShippingLot)

RETURN
END
