Here's[^] some nice basic info about joins and how to do them. It even has pictures

Did you try to write query before you ask here? In your previous question you took good answers which are valid for your question which you are asking.

What you need is a common table expression[^] which is recursive processing of a table.
This may not be correct as your structure seems to be rigid (you know how many level to the top) and therefor you simply do a bunch of inner joins.
Select *
From Fruit
Inner join Category on Category.CategoryID = Fruit.CategoryID
Inner Join level2.ID = Category.Level2.ID
...

Dear Experts,
I am using MS SQL server 2005. I want to Query the records that are not same in two different table.
ie., I have 2 different tables TABLE1, TABLE2 which are having same columns. (and most of the row are same)
Q1 : I want to query the records of TABLE2 which are not avaliable in TABLE1
Q2 : I want to query the records of TABLE1 which are not avaliable in TABLE2
Needless to compare the primay key.
Thanks in advance!!

SELECT a.*
FROM table1 a left outer join table2 b
ON a.id = b.id
WHERE b.id IS NULL
That will show you a list of records that are not in table2.

the ON is what joins the two tables together is the second condition is more to restrict the results then you would put that in the WHERE clause.

Records of TABLE2 which are not avaliable in TABLE1
select * from table2 where ColumnName not in (select ColumnName from table1 )
TABLE1 which are not avaliable in TABLE2
select * from table1 where ColumnName not in (select ColumnName from table2 )

Hi
Is it possible to have 2 foreign keys that ae thesame in one table ?
Create table Product
(
productID int PK
)
Create table Category
(
CategoryID int PK ,
productID1 int fk references Product (productID) ,
productID2 int fk references Product (productID)
)

Yes, although your table name is misleading and it looks like a design nasty to me.
Do you ALWAYS have EXACTLY 2 products in the Category (name seems wrong) table.

What you are asking is possible; however, be sure that your design is right. Off the top of my head, I thing a Category can have 1 or several products.
If that is the case, then I would have my tables as follows
Product(ProductID, CategoryID, ProductDesc,...)
Category(CategoryID, CategoryDesc,......)
Category ID would be a foregn in the product table
|
|
|
|
|
What if the product can belong to more than one category? (as is true in a real world situation).
|
|
|
|
|
Based on the question, it would be impossible to tell.As you can see my answer was conditional. Of course if there were many products for category and vice-versa, then a many-to-many relationship would exist which would be decomposed to two one-to-many relationships. The idea was to get the author of the question to think about their design carefully. I was not saying the solution must necessarily be what wrote.

As has already been answered above, yes, it is possible. But your design is flawed. It accomodates only 2 products in a category. What if a category has more than two products?
In a real world situation, a category can have hundreds of products and a product can be classified under multiple categories. You should create what is called a bridge table to address this design question.
Create table Product
(
ProductID int PK
)
Create table Category
(
CategoryID int PK
)
Create table CategoryProductBridge
(
CategoryID int FK references Category (CategoryID),
ProductID int FK references Product (ProductID)
)
|

You're rather presumptuous. Although there are situations in which products and category have a many to many relationship, there are many real world situations in which a product belows to one category.

Only issue is the tables are on different servers.
What would be the best way? I tried looking at BULK INSERT, looks like you can insert into a file.
I tried - insert into A select * from B. It is taking for ever, after almost 3 hours of running the query, I had to kill it.
Any thoughts/ideas would be appreciated.

You've not mentioned which DB this is for, or if it is for two different vendors perhaps. But I would think for table replication involving 84 million rows, you should be investigating table export/import operations associated with the databases.

Apologise! It is sql server 2005.

Is this a one-time operation? If so, I'd simply backup the database, restore it on the other server, and do a "select into" in the night.
If the tables need to be in sync, I'd probably go for replication.

Backup and restore sounds like a good idea.
Why would I "select * into" again?
Also, I read that "select * into" is faster than "insert into select * from"?
I guess it would one way, since there will no indexes on the table, right?
thanks a lot!

I haven't compared them, just a habit of dumping new data in it's own table. If you want to speed up the copy further, then try to have the "source"-database on another diskdrive then the "destination" database.
