I am getting the following error in the database..
B-tree chain linkage mismatch
Keys out of order on page
I have run the DBCC Repair_rebuild with data_loss.
But this has not helped to resolve the issue. It is finding errors in the Primary Key Linkage.
Please assist.
Thanks for your help.

Probably not the best "Subject Title", but no the less what I am looking for is a way to get the order in which I should insert data into a table that has 10 FK's to it. I have queries that list them out for me, but they do that in what seems to be alphabetical order. You can also right click the table in question and select view dependencies, but that as well appears to be in alphabetical order.
Is there any query or any way to see what order I should be inserting and/or deleting data into FK tables?
lol, you still still didn't answer the most important questions about what you want the results to be, and whether the data is consistent.

hi guys,
the following test script works fine and displays a list of cars from the fairly small database, but if I specify the sort order in the querystring, the page takes ages to display and usually times out. Can someone look over it please and tell me where I can fine-tune it for performance or redundant code?

Hi,
I'm trying to look for an efficient way to select records from two tables, combine them (not just one set above the other) and also efficiently page the results as well as dynamically order by specific columns. So far I have this....
DECLARE @Temp TABLE
(
IDINTNOT NULL,
NameNVARCHAR(128)NOT NULL,
TypeCHAR(1)NOT NULL
)
INSERT INTO @Temp
SELECT i.ID, i.Name, Type = 'I' FROM Item i
UNION
SELECT p.ID, p.Name, Type = 'P'FROM Package p
SELECT * FROM @Temp
ORDER BY Name ASC
I was going to then implement some sort of of ROW_NUMBER like paging and ordering on the @Temp table variable. Problem is there could be potentially 1000's or more Items and Packages and they would all go in this single Temp table before having records 1 to 10 returned. Is there a more efficient way of doing this before I proceed any further?
Many thanks for any help! :)
Hello again,
I'm going through my tables and rewriting them so that I can create relationship-based constraints and create foreign keys among my tables. I didn't have a problem with a few of the tables but I seem to have come across a slightly confusing hiccup.
Here's the query for my Classes table:
Code:
CREATE TABLE Classes
(
class_id
INT
IDENTITY
PRIMARY KEY
NOT NULL,
teacher_id
INT
NOT NULL,
class_title
VARCHAR(50)
NOT NULL,
class_grade
SMALLINT
NOT NULL
DEFAULT 6,
class_tardies
SMALLINT
NOT NULL
DEFAULT 0,
class_absences
SMALLINT
NOT NULL
DEFAULT 0,
CONSTRAINT Teacher_instructs_ClassFKIndex1 FOREIGN KEY (teacher_id)
REFERENCES Users (user_id)
)
This statement runs without problems and I Create the relationship with my Users table just fine, having renamed it to teacher_id. I have a 1:n relationship between users and tables AND an n:m relationship because a user can be a student or a teacher, the difference is one field, user_type, which denotes what type of user a person is. In any case, the relationship that's 1:n from users to classes is that of the teacher instructing the class. The problem exists when I run my query for the intermediary table between the class and the gradebook:
Code:
CREATE TABLE Classes_have_Grades
(
class_id
INT
PRIMARY KEY
NOT NULL,
teacher_id
INT
NOT NULL,
grade_id
INT
NOT NULL,
CONSTRAINT Grades_for_ClassesFKIndex1 FOREIGN KEY (grade_id)
REFERENCES Grades (grade_id),
CONSTRAINT Classes_have_gradesFKIndex2 FOREIGN KEY (class_id, teacher_id)
REFERENCES Classes (class_id, teacher_id)
)
Query Analyzer spits out: Quote: Originally Posted by Query Analyzer There are no primary or candidate keys in the referenced table 'Classes' that match the referencing column list in the foreign key 'Classes_have_gradesFKIndex2'. Now, I know in SQL Server 2000 you can only have one primary key. Does that mean I can have a multi-columned Primary key (which is in fact what I would like) or does that mean that just one field can be a primary key and that a table can have only the one primary key?
In addition, what is a "candidate" key? Will making the other fields "Candidate" keys solve my problem?
Thank you for your assistance.
what the best practice is for creating indexes on columns that are foreign keys to the primary keys of other tables. For example:
[Schools] [Students]
---------------- -----------------
| SchoolId PK|<-. | StudentId PK|
| SchoolName | '--| SchoolId |
---------------- | StudentName |
-----------------
The foreign key above is as:
ALTER TABLE [Students] WITH CHECK ADD CONSTRAINT [FK_Students_Schools]
FOREIGN KEY([SchoolId]) REFERENCES [Schools] ([SchoolId])
What kind of index would ensure best performance for INSERTs/UPDATEs, so that SQL Server can most efficiently check the FK constraints? Would it be simply:
CREATE INDEX IX_Students_SchlId ON Students (SchoolId)
Or
CREATE INDEX IX_Students_SchlId ON Students (SchoolId, StudentId)
In other words, what's best practice for adding an index which best supports a Foreign Key constraint?

View 3 Replies View RelatedHi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.

Hello I have a project that uses a large number of MS Data access pages created in Access 2003 and runs on MS SQL2005.
When I am on lets say my client, (first page in a series) data access page and I have completed the fields in the (DAP), I am directing my users to the next step of the registration process by means of a hyperlink to another Data access page in the same web but in a linked or sometimes different table.
I need to pass data entered /created on the first page to the next page and populate the next page with some data from the first page / table. (like staying on the client name and ID when i go to the next page)
I also need the first data access page to open and display a blank or new record. Not an existing record. I will also be looking to creata a drop down box as a record selector.
Any pointers in the right direction would be appreciated.
I am some what new to data access pages so a walk through would be nice but anything you got is welcome. Thanks Peter��
In SQL Server 2000, I'm looking for input as to how to set up primary keys (PKs).
Is it safe to use the IDENTITY feature using AUTOINCREMENT as a setting for a PK, or is it best to generate my own and check for dups?
My concern is whether SQL Server at any point will taint the numbers used as the PK -- because as you know, these PKs are going to wind up linking into (relating into) other tables (e.g. client orders).
Certainly it's vital that the clientID not get lost/changed during any regular DB maintenance or use.
Any input would be appreciated.
Hi,
The way i generate my primary keys is to keep a table
PrimaryKeyTable
PrimaryKeyName : varchar (name of the primary key, for example UserID)
PrimaryKeyID : int (the next key should have the number stored in that
field, if it was 12 then next time i add a row the UserID will be 12)
After adding a row, i increment the value of primaryKeyID.
Is there a way to let SQL server to handle the primary key? To let SQL generate the key himself instead of me?
Thanks,
I'm creating an asymmetric key in SQL Server:
CREATE ASYMMETRIC KEY MY_KEY
WITH ALGORITHM = RSA_512
ENCRYPTION BY PASSWORD = 'password1@'
I'm then taking the public key...
SELECT public_key
FROM sys.asymmetric_keys
WHERE [name] = 'MY_KEY'
I'm trying to import this into VB.Net using RSACryptoServiceProvider.
Dim RSA As New
Security.Cryptography.RSACryptoServiceProvider(512)
RSA.ImportCspBlob(KeyBlobByteArray)
I have to add the following line to get it to not give me errors.
(Why?) But the data looks right when I look at the exponet and modulus
of the parameters that are exported and then immediately imported.
Something is obviously being thrown away when I do this, but I don't
know what. It's probably the key to the whole problem.
RSA.ImportParameters(RSA.ExportParameters(False))
I encrypt the message...
EncryptedMessageByteArray = RSA.Encrypt(MessageByteArray,
False)
And in SQL server I try to decrypt the message and I get NULL.
SET @DecryptedMessage =
DecryptByAsymKey (
AsymKey_ID('MY_KEY') ,
@EncryptedMessage ,
N'password1@')
I've noticed that the encrypted array is completely different in VB
than when I encrypt it in SQL (obviously), but I can't figure out how
to configure to the RSACryptoServiceProvider to match what SQL Server
is doing under the hood.
Any ideas?
Thanks,
Jerrill
As part of a project, I'm not allowed to use foreign keys, well can't. But I have a problem with this master detail relationship (and a very simple one too).
Tables to begin with:
Invoice:
invoiceid : bigint indentity autoincrement primarykey
Detail:
invoiceid: bigint - detailnumber:bigint - desc : char20
Okay - I want to set these two tables up such than when I create a new invoice, and subsequently get the new invoiceid, and I start to add detail records to the detail table, I want the detailnumber to autoincrement when I do an SQL Insert. Right now I have detailnumber as the primary key, so when you view the detail records, it looks like:
(invoiceid, detailnumber, desc) 1,1,text - 1,2,text - 1,3,text - 2,4, text on another invoice - 3,5, text
I want it to work like:
(invoiceid, detailnumber, desc) 1,1,text - 1,2,text - 1,3,text - 2,1, text on another invoice - 3,1, text
where the invoiceid and the detail number make up the primary key.
I seem to recall you could do this is PHP before it had foreign keys & such, and I'm completely drawing a blank on this. BTW - I'm using enterprise manager to set this up, but I can use QA with a sample script to acheive the same.
I realize this may be (and probably is) off-topic here, but I can't figure out where to ask.
Thanks in advance.
I think I did this before but how do you designate foreign keys in SQL Server Management Studio?

Hi,
There alot of talk about Service Master and DB Master keys and the importance of backing them up seperately.
What about the DPAPI keys used to protect the Service Master keys. What procedures to I take to back those up during my database backup.
If I understand correctly, if I do a backup on one machine, and then try to restore in a different machine, I won't be able to decrypt data becuase the DPAPI keys don't "match".
This is assumming I don't use a password to protect my DB Master keys, I just rely on the service master to protect them.
Thanks for any help,

I've been trying to re-install VS2005 & MS SQL Server express, and I've hit a snag trying to install SQL Server express.
I started by trying to use the automatic uninstaller for VS and had problems so I tried manually uninstalling it (bad idea), which didn't work either, so I re-installed VS completely, then uninstalled it using the automatic uninstaller. I then tried installing, which worked for VS2005, but it didn't work for SQL Server. I've tried 3 times now, and each time it says SQL Server 2005 failed to install.
I checked the summary.txt log found in C:Program FilesMicrosoft SQL Server90Setup BootstrapLOG and from what I understand, it seems that I don't have priveledges to change some registry keys. This has me really lost because I'm installing as Administrator, as you can see from the log below, so I should have access to the registry. Administrator is the only account on the computer so I know I haven't messed up priveledges from another account.
I've included the contents of the summary log below if anyone can make any sense of it and has any ideas I can try.

In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
How shall I achieve this?
I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?
I have a query that calculate the total amount of order details based on a particular order:
Select a.OrderID,SUM(UnitPrice*Quantity-Discount)
From [Order Details]
Inner Join Orders a
On a.OrderID=[Order Details].OrderID
Group by a.OrderID
My question is what if I wanted to create a formula to something like:
UnitPrice * Quantity - DiscountAmount Where DiscountAmount = UnitPrice Quantity * Discount
Do I need to create a function for that? Also is it possible to have m y query as a table variable?

I researched this for a bit but found no straight answers. My table has no PK, but an identiy column.

AS
BEGIN
INSERT INTO PurchaseOrder (PurchaseOrderDate, SupplierID) VALUES(@date, @SupplierID)
END
SET @POno = @@IDENTITY
RETURN
However, how do i make it that it will automatically adds item under the POno being gernerated? can i use a trigger so that whenever a Insert for PO is success, it automaticallys proceed to adding the items into the table PurcahseOrderItem?
CREATE TRIGGER trgInsertPOItem
ON PurchaseOrderItem
FOR INSERT
AS
BEGIN
'What do i entered???'
END
RETURN
help is needed asap! thanks!
