DB Design :: How To Copy Data From Existing Table To Normalized Tables
May 20, 2015
I normalized the below tables but I am finding it difficult to copy data to the new tables. How do I copy data from existing table to the normalized tables? see the table structure below and other supporting information:
SKU_DATA(SKU,SKU_Description,Department,Buyer) Note: this table already has data in it.
CREATE TABLE SKU_DATA (
SKU
Integer NOT
NULL,
[code].....
The table structure above have two three determinants( SKU,SKU_Description and Buyer). SKU and SKU_Description are candidate keys. Primary key is SKU.
Normalization : SKU_DATA(SKU,SKU_Description, Buyer)
BUYER(Buyer,Department)

I have a "source" table that is being populated by a DTS bulk importof a text file. I need to scrub the source table after the importstep by running appropriate stored proc(s) to copy the source data to2 normalized tables. The problem is that table "Companies" needs tobe populated first in order to generate the Identity ID and then usethat as the foreign key in the other table.Here is the DDL:CREATE TABLE [dbo].[OriginalList] ([FirstName] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[LastName] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[Company] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[Addr1] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[City] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[State] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[Zip] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[Phone] [varchar] (255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL) ON [PRIMARY]GOCREATE TABLE [dbo].[Companies] ([ID] [int] IDENTITY (1, 1) NOT NULL ,[Name] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]GOCREATE TABLE [dbo].[CompanyLocations] ([ID] [int] IDENTITY (1, 1) NOT NULL ,[CompanyID] [int] NOT NULL ,[Addr1] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[City] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[State] [varchar] (2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[Zip] [varchar] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[Phone] [varchar] (14) COLLATE SQL_Latin1_General_CP1_CI_AS NULL) ON [PRIMARY]GOThis is the stored proc I have at this time that does NOT work.

Ok, I'm fairly new to .NET and even newer to the whole database concept. But, don't run away yet, I'm no idiot and I shouldn't have too hard of a time understanding your responses if you're kind of enough to give them. That being said, here's my dilemma:I'm trying to make a database of all the movies I own, the actors in them and the genre (s) they belong to. I have a set of tables that are in the 2NF (I think). I have a movies table, an actors table, a genres table, and two tables called movies_actors and movies_genres with primary-foreign key relationships to pull it all together (e.g. movie_id 1 has two entries in movies_genres, one for Action and one for Drama). My problem arises that when execute my monster query to pull ALL the data on one movie, I get a row returned for every combination of Genres and Actors in a movie. Example:movie_id movie_title comments actor_first actor_last genre_name1 Casino blah blah Robert DeNiro Action1 Casino blah blah Robert DeNiro Drama1 Casino blah blah Joe Pesci Action1 Casino blah blah Joe Pesci Drama And here's the query that produced that:1 SELECT movies.movie_title, movies.comments, actors.actor_first,
2 actors.actor_last, genres.genre_name
3 FROM movies INNER JOIN movies_actors ON movies.movie_id = movies_actors.movie_id
4 INNER JOIN actors ON movies_actors.actor_id = actors.actor_id
5 INNER JOIN movies_genres ON movies_genres.movie_id = movies.movie_id
6 INNER JOIN genres ON movies_genres.genre_id = genres.genre_id
So, I want to put all the actors for one movie into the same cell in the datagrid (same with the genres) and still keep it sortable by actor or genre. Is this possible with the .NET 2.0 datagrid? Do I have some fundamental misunderstanding of how my tables should be structured? Am I just really far off and acting like a n00b?

Hello,
I am pretty new to SSIS, so please excuse me if this is a trivial question.
I have a denormalized database table in an Access database that I need to import into several different tables in a SQL 2005 database. You can think of the Access table as a CustomerOrders table. For example customer related information (i.e. CustomerName, CustomerID, etc...) is repeated with each record in the Access table. When this data gets moved to the SQL 2005 database, I need to insert one record for each distinct CustomerName/Customer ID record into a Customers table. I then need to insert and link every "Order" record into an "Orders" table.
I am sure that this is probably a pretty common task, but I have not found any examples or articles explaining this particular situation. What ways can this be done?
I was thinking I need to loop through each DISTINCT Customer record in the Access (source) table and insert a Customer record into the destination database's Customer table. I would then need to iterate through each row of the Access (source) table and "Lookup" the appropriate CustomerID/Key Field and insert an "Order" record.
The Access table contains over 75,000 rows of data. I am looking for the most appropriate way of doing this with SSIS (so that I don't have to write a custom application to do this!). Any help, input, links, articles, etc. is appreciated!!
TIA
-Brian

I have a requirement to provide data in a denormalized form from normalized tables. Working in SSIS.
I have two tables: EmployeeCountry and Country.
EmployeeCountry
EmployeeId (PK)(FK)
CountryId(PK)(FK)
Country
CountryId (PK)
CountryName
There will only be a max of 3 Country entries for each Employee. So I want to select the EmployeeId and get the three CountryIds so it would look like this:
Employee
EmployeeId
CountryId1
CountryId2
CountryId3

First of all, this is my initial thread here on dbforums. I come from the land of Broadband Reports and would like to say, Hello fellow DB enthusiasts. :)
I'm not a novice to relational databases (Access MDBs), but new to implementing a db via SQL SERVER (2000 in this case) and using Access Data Projects.
My partial db schema is as follows:
participants
---DID (pk) char(1)
---LID (fk - schools) char(4)

4 | CCRC | CHILD CARE RESOURCE CENTER
5 | CHSC | CHILDREN'S HOME SOCIETY OF CALIFORNIA
==========================================
THE REMAINING "FKs" FROM SCHOOL ARE SIMILAR, as is other tables and their relationships. The design of the foreign keys were made using sql and the keyword "REFERENCES" and "FOREIGN KEY."
My questions are: :confused:
(1) Is the use of FK as a Constraint any different than using an INDEX and how?
(2) Should I Alter the Tables to include CASCADING Up/Down?
(3) Are the use of CHARs Ok for the Keys?
(4) Have I over/under-normalized any of the relationships?

We want to add a new int identity column as a primary key to an already existing table that has a primary key on Guid. Here is the DDL:
CREATE TABLE [dbo].[VRes](
[VResID] [uniqueidentifier] NOT NULL,
[Mes] [varchar](max) NOT NULL,
[PID] [uniqueidentifier] NOT NULL,
[Segt] [int] NOT NULL,
[code]....
Also we currently have 3 million rows on this table. Is having an integer column as identity column and primary key better or shd I consider using BigInt?

hi,
i have a table with data in the following format (dont ask why it was done this way, its not something i can change)
so my table looks like this:
point :timestamp :value
_________________________
var1 11:00 5
var2 11:00 2.3
var3 11:00 21
var1 12:00 5.2
var2 12:00 2.4
var3 12:00 18
and so on.
i would like to have my data rearranged to look like the following:
timestamp :var1 value :var2 value :var3 value
________________________________________________
11:00 x y z
12:00 a b c
....
i am working with my database in a c sharp application. so if anyone does come up with a solution for this maybe keep that in mind so that i can discuss how to impliment it in the code.
thanks guys.

Dear Experts,When I use a single table I can easily use constraints to enforce mybusiness logic, but what do I do when I normalize a single table intomultiple tables.For example, imagine that my initial table has the columns ID, Name,Salary with the constraint that Salary is not NULL. Now imagine thatI break this into two tables, one with ID and Name and another with IDand Salary. I would like to have a constraint that prevents thecreation of a row with (ID,Name) in the first table unless acorresponding row in the second table is also created.I can enforce this logic with triggers, but it looks ugly and isfairly brittle. Is there a better way or is this the dark side ofnormalization?Thanks.

Hi there -
First of all I think of myself as a software developer and by no means a database expert. So I am posting a question here hoping that someone will lead me in the right direction.
I am somewhat following the database diagram from AdventureWorks with my own "normalized" database and have a question on how to update the table(s).
Here is my situation:
Table: Client
ClientID (PK)
Name
...
Table: Address
AddressID (PK)
AddressLine1
AddressLine2
City
...
Table: AddressType
AddressTypeID (PK)
Name
...
Table: ClientAddress
ClientID (PK1)
AddressID(PK2)
...
The tables should be referenced properly, etc... So my question is, when I add a new Client record, how and when do I update the Client table, Address table and ClientAddress table? If my PK on the Client and Address tables is an autoincriment, do I need it before I can update the ClientAddress table? If so, what do I have to look for, or how do I get the newly created ID to update the ClientAddress?
Is this making any sense? - I'm a little lost/confused. So if anyone can provide me links to where I can learn more about stuff like this and/or post some ideas/solutions, I would greatly appreciate it. Also, if I am not clear on my issue, please ask and I will see if I can clarify it more.
Your help is appreciated in advance!

I have three tables :
England_Summer_2001
England_Summer_2002
England_Summer_2003
The tables have the following columns :
Player, Position, [From], [To], Fee, Type, ID, League, Window
I want to create a new table, EnglandFinal with all the data from the three tables although I'm guessing it would not be a good idea to copy the primary keys (ID column) as they would clash.
I have played around with CREATE and INSERT into and UNION but I get various errors. I'm sure I've done this before!
This creates a table from a single table :
select * into Final
from England_Summer_2001

Hi guys , assuming right now I already create partition function (PF_Date) and partition scheme (PS_Date). Let say I would like to implement the partition on the existing tables ( eg: transaction table which is in PRIMARY filegroup), how am I switch it from PRIMARY to PS_Date ? Is it I have to re-create the particular table then only able to put in the partition scheme? Hope can get any assistance here. Thanks alot.

I have a real table with an identity column and a trigger to populate this column.
I need to import / massage data for data loads from a different format, so I have a temp table defined that contains only the columns that are represented in the data file so I can bulk insert.
I then alter this table to add all the other columns so that it reflects all the columns in the real table. I then populate all the values so that this contains the data I need.
I then want to insert into the real table pushing the data from the temp table, however this gives me errors stating that the query returned multiple rows.
I specified all the columns in the insert grouping as well as on the select from the temp table.
ANY thoughts / comments are appreciated. This is beginning to drive me nuts.

I am developing a Content management system of sorts and I want it
to be pretty flexible. I have noticed that with web content (News,
Articles, Events, FAQs) that there is a lot of similarity between these
items. They all have the same basic fields:
TitleSynopsisBodyStartDateEndDate
(for News, Articles, FAQs start and end date can be used for content
expiration. For events, they are used for the actual event dates.)
But for some types of content, I will need fields specific to that
type. For instance, I want to have a few custom settings for a "Photo
Gallery" type, like, how many rows/columns of thumbnails to display per
page.
I feel like I have 3 options, but would really appreciate your advice. I created diagrams for the 3 options, located here: http://nontalk.com/dbdesign/

I'm working on a couple projects and I've recently been trying to make everything fully normalized so updates are easier and I'm just wondering if there's a standard way to query and update normalized tables.
For example:
If I have table People with columns ID, FirstName, LastName, Height, Weight, ShoeSize, I can normalize that into two tables. Table People has ID, FirstName and LastName. Table PeopleDetails has PeopleID (FK), Property and Value. That way i can add more properties later right at the presentation layer if I like. Essentially I moved the data from being horizontal to being vertical.
But doing a simple search for people means I have to search the details table and return a LOT more records (one each for Height, Weight and ShoeSize) not to mention any more details I might add later. With a lot of details, it seems like your performance would take a big hit and your code would get really complicated as your looping through a vertical dataset to find the properties you want. Or is there some other standard way of doing that?
I'm just hoping that someone else has solved these problems and there's a standard set of functions out there for selecting and updating this kind of DB structure. Anyone?

any ideas on how i could do this easily?

Hi there;
i've recently designed a new db for my portal website, and wanna move
the old data from former db to the new one. The problem is that
for the 'News' table, for instance i have two different schemas:Old >>News(id,title,summery,text,date, ... , (old columns) , ...)New >> News(id, title , summery , text , date, lastUpdated, ... , (new columns) , ...) i
want to copy the bolded columns, and want to have 'lastUpdated' &
'date' in the new table to be the same as 'date' in the former one.as i googled, i just found materials on copying dbs to production servers, or cross db scenarios. thanks in advance

Hi,
I have a problem in design the tables. My main task is to learn how to give the Match Score.
I have hundreds of dataset and one of them is like this:
Test Record Number: 19
Prospect ID = 254040088233400441105260031881009
Match Score = 95
Input Record Fielding ( eg wordnumber[Field] ) : 1[1] 2[1] 3[11] 4[11] 5[11]
Prospect Word = 1 type = 1 match level = 4 input word = 1 input type = 1
Prospect Word = 2 type = 2 match level = 0 input word = NA input type = NA
Prospect Word = 3 type = 3 match level = 4 input word = 2 input type = 1
Prospect Word = 4 type = 11 match level = 4 input word = 3 input type = 11
Prospect Word = 5 type = 13 match level = 4 input word = 4 input type = 11
Prospect Word = 6 type = 14 match level = 4 input word = 5 input type = 11
Now I have all my data stored in the DB and I seperated them into 3 tables and their structures are:
1) prospect (id, testrecordnumber, prospectID, matchscore)
2) inputfieldind (id, prspid, inputword, inputfield)
3) prospectinfo (id, prspid, prospectword, prospecttype, matchlevel, inputword, inputtype)
and the prspid in table 2 & 3 refers to the prospectID in table 1.What I did was setting:
a) prospect table as case table with id AS key, prospectID AS input & predictable;
b) and the other two as nested tables with inputword/inputfield AS key & input, prospectword/prospecttype/matchlevel/inputword/inputtype AS key & input .
But it shows error for having multiply key columns...
And also I am thinking about using the Naive bayes algorithm. Can I also have some suggestion on this?
Thanks
