Hi everyone, I am trying to upgrade a 2000 DB to 2005 with SSIS Database Transfer.
I finally got it to work with an online transfer but the destination database has no primary keys, indexes or identity columns from the source DB.
What am I missing?
What other ways are there to upgrade a SS2000 DB to 2005?
Thank you.
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?
I set up a task to do a transfer of a SQL 2000 db to SQL 2005 in Integration Services (selected my servers, dbs, and chose DatabaseOnline method). In debug mode it processes for a little while and finally errors with:
[2] Progress: Starting database transfer.. Step 1 out of 2 complete
Error: The Execute method on the task returned error code 0x80131500 (An exception occurred while executing a Transact-SQL statement.). The Execute method must succeed, and indicate the result using an "out" parameter.
Task Transfer Database Task failed
Finished, 4:01:24 PM, Elapsed time: 00:10:39.422
I set up a basic Transfer Database task (online, copy) to copy a DB. It works great except for the fact that it isn't transferring the PK's and FK's. It also looks like it did not transfer the views. Any idea why? Anything else the Transfer Database task doesn't actually transfer?
View 2 Replies View RelatedI have a 3rd party app which had a primary key with about 5 fields. The last field of this was a trantype. This app had a posting process which uses this in it's sql. Ran rather slow. We added an individual index to this field and cut processing down 90%. It almost seemded like sl server was ignoring this index. Is this because it was the last field in the primary key index?
View 1 Replies View RelatedAll of the 3 books I've read say it is not a good idea to create a clustered index on the primary key but it is created as the default. My question is has this changed in 2005? My understanding is to create the clustered index on columns used first in join clauses and then in where clauses, what is the answer?

Reguarding indexes, should i make the auto # colm my pk and make that the clustered index? and put another index on the Deal Colmn? Any suggestions welcomed

I wanted to find all occurrences of ADRSCODE in a Database where ADRSCODE is in either an Index or a Primary Key.
I know how to get all of the occurences of ADRSCODE in a database and the table associated with it, I just want to tack on the Index and/or primary key.
SELECTOBJECT_NAME(object_id)FROMsys.columns
WHEREname
='foo'
How can I get the other bit of information ?

Hi,
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 table which has a composite primary key consisting of four columns, one of them being a datetime called Day.
The nice thing afaik with this composite key is that it prevents duplicate entries in the table for any given day. But the problem is probably two-fold
1. multiple columns need to be used for joins and I think this might degrade performance?
2. in client applications such as asp.net these primary keys must be sent in the query string and the query string becomes long and a little bit unmanagable.
A possible solutions I'm thinking of is dropping the existing primary key and creating a new identity column and a composite unique index on the columns from the existing composite key.
I would like to have some tips, recommendations and alternatives for what I should do in this case.
Hello,
I created ssis package to transfer tables from one DB to another.
However, I don't find the option where I can make that the transfer with the indexes and pks of the tables. in sql2000 I had this option.
appriciate your help.

We are currently running sql 2000 and are moving our database onto sql 2005 running on a different box.
We have managed to move the entire database, with users however the users permissions on specific tables/views/stored procedures have not been transferred, does anyone know a way of transferring user permissions rather then doing them all by hand?
The system is a large (over 500 table/views/stored procedures) and a very active one and therefore downtime is not optional.
any suggestions would be appreciated

Hi!
I have seen two approaches to primary keys. First one - and it is like
default - is to use surrogate key as primary key. For each table I will
create some autonumeric field hat cannot be changed once it has value.
Some materials refer to this key also as technical primary key. I
design my databases this way usually.
The other approach is to create primary key of fields that make primary
key on database logical model. This approach is not so popular and has
some side effects like a little bit clumpsy looking joins and
unconvenient use in applications.
Question: What is the main idea behind second approach? Or how explain their preference database designers who are using second approach?
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.
Pls let me know How I generate script for All primary keys and foreign keys in a table. Thereafter that can be used to add primary keys and foreign keys in another databse with same structure.
Also how I script default and other constraints of a table?
Can somebody explain to me how to best do inserts where you have primary keys and foreign keys.l'm battling.
Is there an article on primary keys/Pk ?
Is it possible/advisable when transfering very large amounts of data from server to server to:
trasnfer the data to a new table first
second alter new table adding indexes, defaults, ets based on original table
if it is what flow item would be used to transfer/alter the indexes and defaults?
I'm very new to ssis so the more detail you can give the better.
Thanks
Hello, I'm running an MS SQL 2005 database which supports our entire website and it's fairly huge. I seem to have lost the sa password for the database.
I COULD get it back if there was a way to convert the SQL 2005 DB to an SQL 2000 DB, seeing as how I found a password cracker for that version. Is there anyway to convert a 2005 DB back to a 2000 DB?
Does anyone have any other ideas they might want to lay on me?
I'm kind of sick about this... I'm usually a really good note-taker; In fact, I do have the sa password recorded in an IT database that I keep. Unfortunately the password just doesn't work. I've tried the caps lock and other variations, but the password just eludes me.
Thanks for your help,

I've had a VB 6 / SQL Server 2000 app running in a network enviroment for a couple of years now at a client of mine. Recently, he upgraded to the latest version of Quickbooks which installed SQL Server 2005 on the server. Now there is SQL Server 2000 and 2005 residing on the same server. My VB app still runs on the server but will not run on other machines. I can ping the server from the other machines. Has SQL 2005 taken over the port I was using or maybe has new security features that won't let me access SQL 2000 using my current connection string? Here is my current connection string:
mstrConnStr = "Provider=SQLOLEDB.1;Persist Security Info=True;User ID=" & strServerLogin & ";Password=" & strServerPW & ";Initial Catalog=" & strDBName & ";Data Source=" & strServer.
Any help will be greatly appreciated.

Hi all,
Recently, I upgraded one of our database servers from SQL 2000 to SQL 2005. At the moment, all the databases are in 80 compatibility mode. I upgraded them based on the false pretenses that I could perform online reindexing right off the bat. Apparently, that isn't the case, and it requires switching to 90 compatibility. My question is if I switch to 90, will all indexes be invalidated/unusable? Or will I be able to switch to 90 and perform the online reindexing right away with no downtime?
We have a few 24/7 production VLDB's in the mix (one of which is on this newly upgraded server), and only reasonable downtime is possible. The largest window of downtime I have is about 10 PM - 5 AM with prior notice.
The upgrade was performed using SAN-based LUN's with a detach/reattach.
Thanks,
Matt
Hello
I am creating a TABLE
CREATE TABLE [dbo].[TbTest](
[id_TbTest] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED ,
[Title] [varchar](100) NULL,
) ON [PRIMARY]
when looking at the Column Properties in MS Server Management Studio I get :
Identity Specification = Yes
(Is Identity) = Yes
Increment = 1
Seed = 1
now if I want to make a copy of that database, importing datas and tables
I get :
Identity Specification = No
(Is Identity) = No
How can I avoid this problem ? my application is not working anymore
ALTER TABLE [dbo].[TbTest] WITH NOCHECK ADD
CONSTRAINT [PK_TbTest] PRIMARY KEY CLUSTERED
(
[id_TbTest]
) ON [PRIMARY]
is not solving that problem
thank you
i have some confusions with keys and indexes.. plz let me know whether the following are correct..- Every Primary Key is a Clustered Index- A Primary Key cannot exist without a Clustered Index- Every Unique Key is a Non-Clustered Index - Non-Clustered Index is the DEFAULT Index- A table can have only 1 Primary key- A table can have only 1 Clustered Index- A table can have any number of Unique Keys- A table can have any number of Non-Clustered Indexes
Recently moved a couple of dbs from SQL 2000 -> SQL 2005 (different machine). Just restored the dbs on the new server from a full backup of the old one. Everything is fine but...
Some queries are returning out-of-order results (for records added since the migration). I tracked this down to the indexes. I completely rebuilt and reorganized the indexes (online) through the manager interface. This helped provide correct ordering for existing records, but new records added since the re index are still out-of-order.
Looking for a way to permanently fix the indexes so I don't have to constantly rebuild them.
Thanks.
