Preserving Primary Key Constraints In DTS Wizard
May 9, 2006
I have a problem that has been frustrating me for a long time, simply because I know this has to be somewhere but I cant seem to find where to toggle this setting.
I have a large number of tables that I regularly send to a remote server using the DTS Export Wizard in SQL Server Management Studio 2005.
Although I have toggled "Enable Identity Insert", as well as "Drop and Recreate Destination Tables", my tables upon completion are missing their primary key constraints, as well as its Identity attribute.
I have to go in manually to each table and set the column that is the PK, and the Identity attributes - all my stored procs break as a result of the missing constraint.
What setting do I need to flag during the DTS Export that will preserve the key values for me on completion?

Hi Folks,
I would like to create a table with primary key pair:
Key1 : nchar(10)
Key2: nchar(10)
Value: money
That is, Key1 and Key2 are the primary key columns for the table. I would like to think of (Key1='Foo', Key2='Bar') to be the "same" as (Key1='Bar', Key2='Foo'). Is there a way to enforce this as a table constraint, or do I have to enforce this manually in all procedures that modify and read the table?
Thanks!

Hi,
We will be using SQL Compact Edition in our application. We are doing some tests to make sure that SQL Compact is suitable for our requirments.
Our problem is with Primary keys and how to maintain data integrity since we will have 100+ clients inserting, updating, and synchronizing with SQL Server.
Can we control Identity range?
Shall we use UniqueIdentifires insted of int?
How can we detect errors at the client side? (For example, if two clients are trying to synchronize 2 columns with the same primary key value)
We will use Merge replication.
Thank you

Ok, so I've broken down and decided to write myself an invoicing
program. I'd like to use GUID fields as the Primary Keys in my
table. Now, I basicly bill for two seperate items:
Deliverables and Services.
So, my Layout's gonna look something like
Create Table Invoice(
ID UniqueIdentifier Primary Key,
-- Other Data
);
Create Deliverable(
ID uniqueidentifier Primary Key,
ParentInvoice uniqueidentifier,
-- Other data);
--...
Im sure there are probems with that as it's written feel free to edify me as to what they are.
my questions are such:
1) Does a uniqueidentifier field automagically get a value?
2) If not how do I generate one in TSQL?
3) If so, what do I use to store my Foreign Keys.
4) How do I declare my Foreign key constraints?

I have table variable in which I am inserting data from sql server database. I have made one of the columns called repaidID a primary key so that a clustered index will be created on the table variable. When I run the stored procedure used to insert the data. I have this error message; Violation of Primary key Constraint. Cannot insert duplicate primary key in object. The value that is causing this error is (128503).
I have queried the repaidid 128503 in the database to see if it is a duplicate but could not find any duplicate. The repaidID is a unique id normally use by my company and does not have duplicates.

I have added a Slowly Changing Dimension transformation to an SSIS package and have launched the Wizard to edit it. After selecting the source (a SQL Server 2005 instance), if I select a very large table (9+ million rows), I'm encountering two strange behaviors:
1. The wizard hangs for several minutes before displaying the columns from that table.
2. The wizard does not display the primary key column. This, of course, is the column I want to designate as the "business key", but can't because it's not displayed.
I know this is more like a fact table than a dimension, but this is not a data warehouse. This is just a very large table, and I need to update a field in certain records based on the contents of a source text file. Is there another transformation I should use to perform updates?

I usually do this in VB, so I'm pretty sure my problem is related to c#. I'm trying to save the contents of a multiline textbox into a SQL server NTEXT field. When I do the insert, the SQL looks like (I'm using a stored procedure):
pr_Update 8,1,'line1
line2'
You can see that C# replaced the newline character with
When I look in the table using the management studio, I see line1 (then two boxes) then line2. After I do a select, the string returned is line1
How do I insert text from a multiline text box into sql server, and get it back with the newlines?
Thanks! ---Selden

Hi,
Apologies if this question is similar to one posted under "Click once deployment" but I got no replies and I REALLY need to know the answer to my problem!
I am using VB on VS 2005 Express and SQL Server 2005 Express.
My application is nearing the stage where I can start to use real data (from the end user) for testing purposes. Once I am as happy as I can be, I will install the application on the user's machine and he will use the application for a few weeks, with real data, before giving me a list of problems/suggested improvements etc.
I will then need to make the changes and re-install the application on his machine without losing all the changes he has made to the DB in those weeks.
Presumably, there must be a way of updating the executables without making changes to the DB on the client machine.
This is a very serious issue for me as the data will be around 2,000 records each of over 60 fields and the raw data will come from a variety of sources including paper so the data inputting will be a massive task that I do not want to repeat!
Also, if the application were ever to be sold, then other users would want to apply updates to the software whilst keeping their own data secure.
I have tried re-publishing and installing the application after setting the Publish Status of the DB files to "Exclude" but the newly installed application fails to connect to the old version of the DB.
I would very much appreciate any help in this matter as I hope I haven't just wasted several months of coding!

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.

I have a bunch of records of the following layout:
A B 1235
A B 1236
A B 1237
A C 1238
A C 1239
When I run my script, I want to aggregate these together, but preserve the starting and ending record ids in two new columns:
A B 1235 1237
A C 1238 1239
Can I do all of this in an Aggregate Transformer, or do I need to derive some columns first?
Thanks!

Hi,
Using Management Studio, when I import data from one identical database to another, any identity specifications get dropped from the destination database.
(From columns which have them on the source database and which had them on the destination database.)
Any way to avoid this?

Hi All,
I have become frustrated and I am not finding the answers I expect.
Here's the gist, we support both Oracle and SQL for our product and we would like to migrate our Clients who are willing/requesting to go from Oracle to SQL. Seems easy enough.
So, I create a Database in SQL 2005, right click and select "Import Data", Source is Microsoft OLE DB Provider for Oracle and I setup my connection. so far so good.
I create my Destination for SQL Native Client to the Database that I plan on importing into. Still good
Next, I select "Copy data from one or more tables or views". I move on to the next screen and select all of the Objects from a Schema. These are Tables that only relate to our application or in other words, nothing Oracle System wise.
When I get to the end it progresses to about 20% and then throws this error about 300 or so times:
Could not connect source component.
Warning 0x80202066: Source - AM_ALERTS [1]: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.
So, I'm thinking "Alright, we can search on this error and I'm sure there's an easy fix." I do some checking and indeed find out that there is a property setting called "AlwaysUseDefaultCodePage" in the OLEDB Data Source Properties. Great! I go back and look at the connection in the Import and .... there's nothing with that property!
Back to the drawing board. I Create a new SSIS package and figure out quickly that the AlwaysUseDefaultCodePage is in there. I can transfter information from the Oracle Source Table to the SQL Server 2005 Destination Table, but it appears to be a one to one thing. Programming this, if I get it to work at all, will take me about 150 hours or so.
This make perfect sense if all you are doing is copying a few columns or maybe one or two objects, but I am talking about 600 + objects with upwards of 2 million rows of data in each!!
This generates 2 questions:
1. If the Import Data Wizard cannot handle this operation on the fly, then why can't the AlwaysUseDefaultCodePage property be shown as part of the connection
2. How do I create and SSIS Package that will copy all of the data from Oracle to SQL Server? The source tables have been created and have the same Schema and Object Names as the Source. I don't want to create a Data Flow Task 600 times.
Help!!!

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.
Regards
Mike

Hi,
I have the following problem:
I have a table called Jobs with the fields:
JobNumber, Name, Customer, ...
And a table called Customers with the fields:
ID, Name, Address, ...
Obviously Jobs is linked to Customers with the Customer<->ID fields. I want to set it up so that if a Customer is deleted, then any Jobs that had that customer listed now have the Customer field set to NULL. Can I do this with a constraint, or will I need to use a trigger?

I am fairly new at SQL and also new to this forum. So I don't know if this topic belongs here or not.
But anyways, I found this tutorial online. However, I am having trouble completing it. Can someone please help me?
Given the following table definitions:
CREATE TABLE USERS
(
USERID CHAR(5) PRIMARY KEY,
NAME VARCHAR(30),
RATING CHAR(1) CHECK (RATING IN (A, B,C,D)
)
CREATE TABLE ITEMS
(
ITEM_NO NUMBER PRIMARY KEY,
DESCRIPTION VARCHAR(50),
OFFERED_BY CHAR(5) REFERENCES USERS(USERID) ON UPDATE CASCADE ON DELETE CASCADE,
START_DATE DATETIME,
END_DATE DATETIME,
RESERVE_PRICE NUMBER
)
CREATE TABLE BIDS
(
USERID CHAR(5) REFERENCES USERS ON UPDATE CASCADE ON DELETE SET NULL,
ITEMNO NUMBER REFERENCES ITEMS(ITEM_NO) ON UPDATE CASCADE ON DELETE CASCADE,
BID NUMBER,
BID_DATE DATETIME,
PRIMARY KEY(USERID,ITEMNO,BID_DATE)
)
Directions: Indicate whether the statement is accepted or rejected; and if accepted indicate its effects. Evaluate each statement INDEPENDENTLY.
1) INSERT INTO ITEMS VALUES(1009, Red Bicycle,U01,1999-01-08, 1999-02-10, 30)
2) UPDATE ITEMS SET ITEMNO=1008 where ITEMNO=1001
3) DELETE FROM ITEMS WHERE ITEMNO=1005
4) INSERT INTO ITEMS VALUES(1010, Green Bicycle,U07,1999-01-08, 1999-02-10, 30)
5) UPDATE BIDS SET ITEMNO=1011 WHERE ITEMNO = 1001
6) DELETE FROM USERS WHERE USERID=U01
7) UPDATE ITEMS SET ITEMNO=1020 WHERE ITEMNO=1001
8) DELETE FROM BIDS WHERE BID > 1001
Thanks. I would greatly appreciate your help.

Hi all
I have the following table
CREATE TABLE [dbo].[property_instance] (
[property_instance_id] [int] IDENTITY (1, 1) NOT NULL ,
[application_id] [int] NOT NULL ,
[owner_id] [nvarchar] (100) NOT NULL ,
[property_id] [int] NOT NULL ,
[owner_type_id] [int] NOT NULL ,
[property_value] [ntext] NOT NULL ,
[date_created] [datetime] NOT NULL ,
[date_modified] [datetime] NULL
)
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance
- property_instance_id will never be a foreign key into another table
- queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row
- Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
Thanks Matt
