View Behaviour In Join

Jul 20, 2005

Hi Everybody,I have a complex view, that includes a "group by" clause. I'm tryingto join this view with a table, in a very simple query.The problem is that the optimizer is not using the table data as inputfor the view (I expect this because I have arguments for the table,but not for the view), but executing the view in a different step andthen joining to the table by a merge/hash join. This is obviously veryslow.I tried to force nested loops by using hints but it still doesn't usethe table data as input.Has anybody ever seen this?Thanks in advance...

Replace View By Join

May 23, 2007

Hi all,

I have a list of Clients like:
Table_Client

ID
Name

10
Bill

11
Frank

12
Carl

13
Rita

14
Jan

15
Bonny

16
Bart

17
George

18
Ann

Now I want to ad some variable data to each client, so I have created a second table like:

Table_Client_Data

ID
ClientID
FieldName
FieldDataString
FieldDataInt
FieldDataDate
FieldDateBoolean

2
10
CustomerNr
g146

4
11
CustomerNr
g121

5
12
CustomerNr
g147

6
13
CustomerNr
g236

7
15
CustomerNr
g245

9
10
Dog

yes

10
11
Dog

No

10
12
Dog

yes

10
13
Dog

No

10
15
Dog

yes

Now I want to have the next table as result in one query:

ID
Name
CustomerNr
Dog

10
Bill
g146
yes

11
Frank
g121
No

12
Carl
g147
yes

13
Rita
g236
No

14
Jan

15
Bonny
g245
yes

16
Bart

17
George

18
Ann

First I have made a VIEW to create, I had used a inner Join

SELECT Table_Client.ID,
Table_Client_Data.FieldDataString AS CustomerNr,
Table_Client_Data_1.FieldDataString AS Dog

FROM Table_Client_Data

INNER JOIN
Table_Client_Data ON Table_Client.ID = Table_Client_Data.ClientID
INNER JOIN
Table_Client_Data as Table_Client_Data_1 ON Table_Client.ID = Table_Client_Data_1.ClientID

WHERE (Table_Client_Data.FieldName = 'CustomerNr') AND (Table_Client_Data_1.FieldName = 'Dog')

View_CliuentData

ID
CustomerNr
Dog

10
g146
yes

11
g121
No

12
g147
yes

13
g236
No

15
g245
yes

Now I join View_CliuentData with Table_Client and I have the right result.

Now my question,
Is there any way to skip the View an do this all in a join. I have tried several things but ... no result.

Tks Bart

Join In A View - Simple Question

Jan 19, 1999

I've got a simple ( I think) question on views. I've got a view that has a table join in it.
With this view, we want to be able to perform updates, inserts, and deletes. At this time
we can do the updates and inserts, but not deletes. I've checked the permissions and
the users have SELECT, INSERT, UPDATE, and DELETE. Am I missing something or are
deletes just not possible in a view with a join?

CREATE VIEW update_bd_view
AS select
D.BD_ID, D.BD_DESC, T.BT_TYPE_TID, T.BT_TYPE_FID, T.BT_JOB_FID
FROM BILLING_DESC D JOIN BILLING_TIME T ON D.BD_ID=T.BT_ID
GO

thank you for your time!

SQL 2005 BUG - RIGHT OUTER JOIN On View

Oct 12, 2006

I am having no luck reporting this bug on the feedback link. I type in all information and click "Submit" and it just refreshes the page. So, here it is, I hope someone from MS will post this for me.

The problem appears to be a RIGHT OUTER JOIN on a VIEW causes the query to never return, or return very, very slowly. In 2000 SP4 the query returns in 2 seconds, in 2005 (2153) 64bit, it ran for 42 MINUTES before I killed it.

The is a duplication script to show a problem I have. This script uses the AdventureWorks database to demonstrate the problem. This is script is not the best, but shows the problem.

Please no comments on how to work around the problem. This query is generated by a user using and AdHoc reporting tool. I have NO control over how the user or the tool generates the SQL query.

The word "FAILURE" shows the original query which as far as I can tell never returns. The queries after, are different solutions, if I was able to change the user query, which I am not able to do.

Self Join Using Instead Of Update Trigger On A View

Jan 11, 2008

Hello all...I'd appreciate any help on this one.

I created a View...the view looks at four seperate tables.

Next, I created an Instead of Update trigger on that view. It works fine...for a regular UPDATE...SET.

However, it throws an error when I try an update and self join based on that view:

Update T1
Set RateUsed = T1.RateUsed
From Taxroll..Taxroll T1 Join
Taxroll..Taxroll T2 on
T1.Asmt = T2.Asmt and
T1.Taxyear = T2.Taxyear
Where T1.Asmt = '123456789012'
And T1.Taxyear = 2007
And T2.RollChgNum = ''
And T1.RollChgNum Like '%X'
And IsNull(T1.RateUsed,'') > ''

Msg 414, Level 16, State 1, Line 2
UPDATE is not allowed because the statement updates view "Taxroll..Taxroll" which participates in a join and has an INSTEAD OF UPDATE trigger.

There are a few caveats:
First, I thought the join issue was in the view itself. I re-created the view using no joins...all subqueries and still get the error. Second, I re-created the Instead of Update Trigger with no joins, and still get the error.

Thanks!

Is it possible to do a cross database join in a report services data source view? It doesn't look like it.

If not I was thinking of linking the table into the other database.

(SQL 2000) Incorrect Results When Using An Outer Join And A View!

Mar 29, 2008

Hi,
I have a query written in SQL 2000 which returns incorrect result. The query uses left outer join and a view. I read an issue related to this in one of microsoft bug report in this article http://support.microsoft.com/kb/321541.

However, there's a slight difference in the sympton second bullet wherein instead of a expression the query returns a fixed string for one of the column value.

Although the issue mentioned in article seems to be fixed. The later one still seems to be reproducible even with Service Pack 4. However, this issue doesn't appear in SQL Server 2005.

Here's the query to reproduce this error.

Code Snippetcreate table t1 (pk1 int not null,primary key (pk1))
create table t2 (pk1 int not null,label1 varchar(10) not null,primary key (pk1))
go
insert into t1 values (1)
insert into t2 values (2, 'XXXXX')
go
create view V as
select pk1, 'ZZZZ' as label1 from t2
go
select A.pk1 as A_pk1, B.pk1 as B_pk1, B.label1 as B_label1
from t1 as A left outer join V as B on A.pk1 = B.pk1
go

This query is similar to the one mentioned in the article except that in the SELECT clause of CREATE VIEW statement I am passing a fixed value for column "label1".

I just want to confirm that this is an issue and no fix is available for this so far.

Regards,
Naresh Rohra.

Speed/efficiency Of View Vs. Common/nested Table Expression In A Join

Mar 2, 2008

i have been trying to determine which is the most efficient, with regards to speed and efficiency, between a view and a common/nested table expression when used in a join.

i have a query which could be represented as index view or a common table expression, which will then be used to join against another table.

the indexed view will use indexes when performing the join. is there a way to make the common table expression faster than an indexed view?

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 Outer Merge Join' Failing To Join Valid Row

Aug 10, 2007

Scenario:

OLEDB source 1
SELECT ...
,[MANUAL DCD ID] <-- this column set to sort order = 1
...
FROM [dbo].[XLSDCI] ORDER BY [MANUAL DCD ID] ASC

OLEDB source 2
SELECT ...
,[Bo Tkt Num] <-- this column set to sort order = 1
...
FROM ....[dbo].[FFFenics] ORDER BY [Bo Tkt Num] ASC

These two tasks are followed immediately by a MERGE JOIN

All columns in source1 are ticked, all column in source2 are ticked, join key is shown above.
join type is left outer join (source 1 -> source 2)

result of source1 (..dcd column)
...
4-400-8000119
4-400-8000120
4-400-8000121
4-400-8000122 <--row not joining
4-400-8000123
4-400-8000124
...

result of source2 (..tkt num column)
...
4-400-1000118
4-400-1000119
4-400-1000120
4-400-1000121
4-400-1000122 <--row not joining
4-400-1000123
4-400-1000124
4-400-1000125
...

All other rows are joining as expected.
Why is it failing for this one row?

Multi-table JOIN Query With More Than One JOIN Statement

Apr 14, 2015

I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.

For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.

The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.

The number of rows returned should be the same as the number of rows in OrderDetails.

Select Command - Left Join Versus Inner Join

Aug 9, 2013

Why would I use a left join instead of a inner join when the columns entered within the SELECT command determine what is displayed from the query results?

Merge Join (Full Outer Join) Never Finishes.

Jun 5, 2006

I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?

Why Does My Query Timeout Unless Force Join To Hash Join?

Jul 25, 2007

I'm using SQL Server 2005.

A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).

The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).

If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.

If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.

So, this works:

SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC

and this works:

SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC

But this does't:

SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC

What should I be looking for here to understand why this is happening?

Thanks,

john

Changing From Implicit Join To Explicit Join

Dec 24, 2013

We are trying to migrate from sql 2005 to 2012. I am changing one of the implicit join to explicit join. As soon as I change the join, the number of rows returned are fewer than before.

Below is my Implict join query

INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date)
SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date
FROM #RIF_TEMP0 currow , #RIF_TEMP0 prevrow

[Code] ....

and below is explict join query

INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date)
SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date
FROM #RIF_TEMP0 currow LEFT JOIN #RIF_TEMP0 prevrow
ON (currow.rf0_row_no = prevrow.rf0_row_no + 1)

[Code] ....

the count returned from both the queries is different.

I am not sure what am I doing wrong. The count of #RIF_TEMP0 is always 32, it never changes, but the variable @countTemp is different for both the queries.

Right Join Returns Same Results As Left Join

Feb 5, 2015

Why does this right join return the same results as using a left (or even a full join)?There are 470 records in Account, and there are 1611 records in Contact. But any join returns 793 records.

select Contact.firstname, Contact.lastname, Account.[Account Name]
from Contact
right join Account
on Contact.[Account Name] = Account.[Account Name]
where Contact.[Account Name] = Account.[Account Name]

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.

Super Join - Is Merge Join The Answer?

Nov 7, 2006

Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like ��for every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.

This is the simple sql (no join on the tables):

select 1.code, 2.rowdetail
from tblcodes 1, tblelements 2

But how to do this in SSIS?

Thanks - Ken

Alter View / Create View

Aug 14, 2000

I had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.

I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.

If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.
