Hi.I have 2 tables with this join
dbo.tbl_product_prop INNER JOIN
dbo.tbl_product ON dbo.tbl_product_prop.product_id = dbo.tbl_product.product_id
all the product_id on tbl_product_prop has to be change.
how can I update the product_id of tbl_product-prop with the Product_id of the tbl_product,so when it replace the related information dont change.thanks

I need to construct a database that only has certain elements of another db. I would like to write one batch of commands to either create the tables or update them if the table already exists. I've found examples to update sections of a table, but not the entire thing. Any assistance or relavent links are greatly appreciated.
Thanks,

Here's my update statement:UPDATE Item1SET reviewloop = 1, currentreviewstate=5WHERE itemid in(SELECT itemid FROM Item2)The thing is: the table Item2 DOES NOT HAVE a field called itemid.So, I should receive an error, right? Not so.Instead, every singlerecord in Item1 was updated.Does anyone know why SQL Serverr does not trown an error???Thanks guys,-Silvio Souza

Can any one tell me the difference between Cross Join, inner join and outer join in laymans language
by just taking examples of two tables such as Customers and Customer Addresses
Thank You
I have two xml source and i need only left restricted data.
how can i perform left restricted join?
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 two select statements, in between select statement taking UNION ALL . I need to avoid the error
Warning: The join order has been enforced because a local join hint is used.

All other rows are joining as expected.
Why is it failing for this one row?
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.
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?
View 4 Replies View RelatedI 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?
View 3 Replies View RelatedI'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,

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.
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]
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.
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 €œfor 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
I read that merge joins work a lot faster than hash joins. How would you convert a hash join into a merge join? (Referring to output on Execution Plan diagrams.)

There is a table called "tblvZipCodes" that contain a zipcode of all cities, area code that are located in that zip code.
The problem I have with the inner join is that there are more than 1 cities in one zipcode code. Is there a way to just return only the 1st row and not return the rest of the rows from the tblvZipCodes in the INNER JOIN query?
Thanks..

hello, i am running mysql server 5 and i have sql syntax like this:
select
sales.customerid as cid,
name,
count(saleid)
from
sales
inner join
customers
on
customers.customerid=sales.customerid
group by
sales.customerid
order by
sales.customerid;
it works fine and speedy. but when i change inner join to right join, in order to get all customers even there is no sale, my server locks up. note: there is about 10000 customers and 15000 sales.
what can be the problem?

View 3 Replies View RelatedHi,Just curious. Would you use ANSI style table joining or the 'oldfashion' table joining; especially if performance is the main concern?What I meant is illustrated below:ANSI Styleselect * from a join b on a.id = b.idOld Styleselect * from a, b where a.id = b.idI noticed that in some SQL, the ANSI is much faster but sometimes, theold style looks much better.It's ridiculous to try out both styles to see which is better wheneverwe want to write an SQL statement.Please comment.Thanks in advance.

View 12 Replies View RelatedGiven a table of building components e.g. floors, walls, etc, etc:
create table component_multiplier_table
(
system_code char(4),
system_component_code char(3),

Where function_code is the function of the area e.g. Auditorium, Classrom, etc, etc. And not all components are available for all functions e.g. Carpeting is available for Classrooms but not Power Plants or Warehouses.
I need to self join the above table to itself on system_code and system_component_code and find out which rows are missing from each side.
A query that I've been banging away at with no success is:

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
Take the following scenario:
We have two tables that have somewhat of a parent-child relationship. We are trying to use a SQL-92 outer join that returns the same results as a TSQL *= outer join. The difficulty we are having is that some of the parent records do not have any corresponding child records, but we still want to see those parent records with 0 (zero) for the count. How can we accomplish this with a SQL-92 compliant join (if it is even possible)? In the query results below, we would like the first set of results.
Thanks in advance for any help.

join officedata OD on OD.pk = UO.OFFICE_ID
left join usertitle1 UT on UT.PK = UD.fk_user_title1

I understand that the joins are just brining data that is related the a particular filed but why the LEFT JOIN???

Hello,
I have this table called "Playlist_Items". It has different "media types" in it. An MP3 is "1", a video is "2", etc.
I want to make a query that gets all the items in the playlist and gets common properties between them, like the name, user, etc.
The only problem is that the tables aren't normalized, so I have to do something like, if the "MediaType" is 1 then look in the MP3 table and get this column, otherwise if its 2 then look in the video table. Etc.
I have no idea how to do this in SQL... :/
Here is a diagram of my tables:

Hi,
This is a sample database table
TableA
============================
aID int identity(1,1) primary key
aName varchar(30)
TableB
===========================
bID int identity(1,1) primary key
bTitle varchar(30)
aID int references TableA(aID)
TableC
===========================
cID int indentity(1,1) primary key
cCategory varchar(30)
bID int references TableB(bID)
Here I got two query, are them the same?
Select A.aName, B.bTitle, C.cCategory
From TableA A, TableB B, TableC C
Where A.aID = B.aID And B.bID = C.cID
and
Select A.aName, B.bTitle, C.cCategory
From TableA A Join TableB B On A.aID=B.aID
Join TableC On B.bID=C.cID
Are those two the same?
And what is the different of JOIN and LEFT OUTER JOIN? Any other JOIN?
Millions Thanks!
