I Need Help Normalizing This Table.

Aug 10, 2005

So I'm creating an administrative back end for a site that's already been created, and whoever made the tables the site uses didn't know much about database design. So I need to normalize this table of Links so it can be easier to have someone make changes and updates to it, but then I need to put all my normalized tables back together to create a View exactly like the old table which the old site can select from. Basically the stipulation is I can't change the code for the old site so I have to make it think it's still selecting from the same table with the same type of parameters. Is it worth doing all this? Or should I just tough it out with this really ugly table?Here's the table: and here's the site that uses this table:http://waahp.byu.edu/links.aspThanks!~Cattrah~

Normalizing Using Sql Commands

Aug 28, 2006

Hi

Please can someone point me in the direction, i built a very badly designed database consisting of only one huge table when i first started databases, since learning about normalization i have designed and set up a new database which consists of many more tables instead of just the one. My question is where do i start in transfering the data from the old single tabled database to my new multi-tabled database?

I have MS SQL server 2005 managment studio if that helps, but want to transfer around 200,000 rows of data into the new database. Both new and old databases are on the same server.

thanks in advance

Normalizing A Crosstab

Aug 24, 2006

I re-designed a predecessor's database so that it is more properlynormalized. Now, I must migrate the data from the legacy system intothe new one. The problem is that one of the tables is a CROSSTABTABLE. Yes, the actual table is laid out in a cross-tabular fashion.What is a good approach for moving that data into normalized tables?This is the original table:CREATE TABLE [dbo].[Sensitivities]([Lab ID#] [int] NULL,[Organism name] [nvarchar](60) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[Source] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[BACITRACIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[CEPHALOTHIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[CHLORAMPHENICOL] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[CLINDAMYCIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[ERYTHROMYCIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[SULFISOXAZOLE] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[NEOMYCIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[OXACILLIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[PENICILLIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[TETRACYCLINE] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[TOBRAMYCIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[VANCOMYCIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[TRIMETHOPRIM] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[CIPROFLOXACIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[AMIKACIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[AMPICILLIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[CARBENICILLIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[CEFTAZIDIME] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[GENTAMICIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[OFLOXACIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[POLYMYXIN B] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,[MOXIFLOXACIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[GATIFLOXACIN] [nvarchar](2) COLLATE SQL_Latin1_General_CP1_CI_ASNULL,[SENSI NOTE] [nvarchar](255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL) ON [PRIMARY]

Normalizing Address Information...

Dec 27, 2003

THE LAYOUT:
I have two tables: "Applicant_T" and "StreetSuffix_T"

The "Applicant_T" table contains fields for the applicant's current address, previous address and employer address. Each address is broken up into parts (i.e., street number, street name, street suffix, etc.). For this discussion, I will focus on the street suffix. For each of the addresses, I have a street suffix field as follows:

[Applicant_T]
CurrSuffix
PrevSuffix
EmpSuffix

The "StreetSuffix_T" table contains the postal service approved street suffix names. There are two fields as follows:

[StreetSuffix_T]
SuffixID <-----this is the primary key
Name

For each of the addresses in the Applicant_T table, I input the SuffixID of the StreetSuffix_T table.

THE PROBLEM:
I have never created a view that would require the primary key of one table to be associated with multiple fields of another table (i.e., SuffixID-->CurrSuffix, SuffixID-->PrevSuffix, SuffixID-->EmpSuffix). I want to create a view of the Applicant_T table that will show the suffix name from the StreetSuffix_T table for each of the suffix fields in the Applicant_T table. How is this done?

Set Primary Key When Normalizing Data?

Apr 27, 2006

Greetings all,

I have created an SSIS package that takes data from a very large table (301 columns) and puts it in a new database in smaller tables. I am using views to control what data goes to the new tables. I also specified that it drop the destination table and recreate it prior to copying the data. The reason for this is so that old data removed from the larger database will get removed from the normalized databases.

I have 2 things I am trying to figure out..

1. I would like to have the package set a specific row in each new table to be the primary key (this will allow us to use relationships when querying the data).

2. I decided I wanted to sort the data as it copies. I am using the BI Visual Studio for my editing. In the Data Flow view I cannot seem to disconnect the output from the Source block so I can connect it to the Sort block and then feed that to the output block. What am I missing here?

Thanks

How To Populate Foreign Key In Normalizing Import?

Jun 21, 2006

I am copying data from one denormalized table to a COUPLE of normalized ones.
I am using multicast, following advices from the forum.

The problem I have is that the two destination tables (A and B) are sharing a foreign key relationship.Filling in A is no problem, but when I want to fill in B, I don't know how to populate its foreign key, since the multicast doesn't know the corresponding primary key in table A.

SQL Server 2012 :: Normalizing A Column Containing Lists

Aug 20, 2015

CREATE TABLE CATEGORIES(CATEGORYID VARCHAR(10), CATEGORYLIST VARCHAR(200))

INSERT INTO CATEGORIES(CATEGORYID, CATEGORYLIST) VALUES('1000', 'S01:S03, S09:S20, S22:S24')
INSERT INTO CATEGORIES(CATEGORYID, CATEGORYLIST) VALUES('1001', 'S11:S12')
INSERT INTO CATEGORIES(CATEGORYID, CATEGORYLIST) VALUES('1002', 'S30:S32, S34:S35, S60')
INSERT INTO CATEGORIES(CATEGORYID, CATEGORYLIST) VALUES('1003', 'S40')

The CATEGORYLIST strings are composed of value ranges separated by a colon (:) and multiple value ranges separated by a comma.

The results I need are:

CATEGORYID STARTRANGE ENDRANGE
1000 S01 S03
1000 S09 S20
1000 S22 S24
1001 S11 S12
1002 S30 S32
1002 S34 S35
1002 S60 S60
1003 S40 S40

I have tried taking the original data and parsing it out as an XML file. Is there a less cumbersome way to do this in TSQL?

Normalizing Flat Data / Extract One Of Each Type

Nov 6, 2007

I'm new to SSIS and have run into a problem I'm hoping someone can help me with.

Basically, I have a flat file that looks something like:

ID,Type,Description,Results
1,Test1,This is a test,5
2,Test1,This is also a 1 test,7
3,Test1,This is also a 1 test,13
4,Test2,This is a second test,14
5,Test2,This is also a second test,18

I'm trying to normalize the data by extracting out individual rows that have the same "Type" column value. So what I want is to extract each unique type and description into a separate table. This would give me two new rows, one for a type of Test1, and one for a type of Test2, with the descriptions. Does this make sense? Then I could relate the individual results to these test types. In my scenario, I don't care which description is used; I just want to take the first description that shows up with the associated "Type."

Does anyone have any idea of how I could go about doing this? I could pull out all unique "Types" from the rows with the Aggregate transformation, but I'm trying to figure out how to get the description that goes along with it.

Thanks,

Brian

DB Design :: Normalizing Personal Contact Information

May 22, 2015

I have a large data set with 10s of millions of rows of contact information. The data is in CSV format and contains 48 columns of information (First name, MI, last name, 4 part address, 10+ demographic points, etc.) and I'm struggling with how I should design the database and normalize this data, or if I should normalize this data.

My 2 thoughts for design were either:

Break the columns into logical categorical tables (i.e. BasicContactInfo, Demographics, Financials, Interests, etc.) Keep the entire row in one table, and pull out the "Objects" into another table (i.e. ContactInformation, States, ZIPCodes, EmployementStatus, EthnicityCodes, etc.)

The data will be immutable for the most part, and when I get new data, I'll just create a new database and replace the old one.

The reason I like option 1 is because it makes importing easier, since I can just insert the appropriate columns from each row into the appropriate tables. Option number 2 feels like it would be faster to get metrics on the data, like how many contacts live in which states, or what is the total number of unique occupations in the data set. Plus I'll be able to make relationships between the tables, like which state is tied to which zipcode, which city is tied with which county, etc. Importing that data might be more tricky, since I don't think SQL Bulk Copy will allow for inserting into normalized tables like that.

The primary use for this data is to allow our sales force to create custom lists of contact information based on a faceted search page. The sales person would create the filter, and then I will provide them with the resulting data so they can start making business contacts. Search performance needs to be good. Insert, update, and deletes won't happen once the data has been imported.

What should I look for in designing this database? Any good articles on designing tables around wide data sets like my contact information?

Normalizing Comma Separated String To Multiple Records

Oct 17, 2012

I need to normalise comma separated strings of tags (SQL Server 2008 R2).

E.g. (1, 'abc, DEF, xyzrpt') should become
(1, 'abc')
(1, 'DEF')
(1, 'xyzrpt')

I have written a procedure in T-SQL that can handle this. But it is slow and it would be better if the solution was available as a view, even a slow view would be better.

Most solutions I found go the way round: from (1, 'abc'), (1, 'DEF') and (1, 'xyzrpt'), generate (1, 'abc, DEF, xyzrpt').

If memory serves, it used "FOR XML PATH". But it's been a while and I may be totally wrong.

SQL Server 2012 :: Formatting XML Output - Avoid Normalizing Structure On Client

May 28, 2015

I have a script that resolve's data into xml like this, ex:

<root>
<title>A</title>
<id>1</id>
<nodes>
<node>
<id>2</id>
<title>A.1</title>
</node>
</nodes>
</root>

And works perfectly, but ... how to make sure every item has an element "nodes" ? The case here is for the child leafs obviously. This, because on the client i have to inject this element "nodes" on a json version of this xml, and just wanted to avoid normalizing the structure on the client.

For the root I am using

FOR XML PATH('root'),TYPE; and for the hierarchy that follows
FOR XML RAW ('node'), root('nodes'), ELEMENTS

SQL Server 2008 :: Normalizing Data Prior To Migration (Update String To Remove Special Characters)

Aug 21, 2015

I'm presented with a problem where I have a database table which must be migrated via a "custom tool", moving the data into a new table which has special character requirements that didn't exist in the source database. My data resides in an SQL Server 2008R2 instance.

I envision a one-time query which will loop through selected records and replace the offending characters with --, however I'm having trouble understanding how this works.

There are roughly 2500 records which meet the criteria of "contains bad characters", frequently containing multiple separate bad chars, and the table contains roughly 100000 rows.

Special Characters are defined as #%&*:<>?/{}|~ and ..

While the field is called "Filename" it isn't always so, it is a parent/child table where foldernames are also stored.

Example data:
Tablename = Items
ItemID Filename ListID
1 Badfile<2015>.docx 15
2 Goodfile.docx 15
3 MoreBad#.docx 15
4 Dog&Cat#17.pdf 15
5 John's "Special" Folder 16

The examples I'm finding are all oriented around SELECT statements, to change the output of what I see returned, however I'd rather just fix the entire column using an UPDATE. Initial testing using REPLACE fails because I don't always have a single character as the bad thing in a string.

In a better solution, I found an example using a User Defined Function to modify the output of a select, but I cannot use that UDF in an UPDATE.

My alternative is to learn enough C# to modify the "migration tool" to do this in-transit, but I know even less about C# than I do of SQL.

I gather I want to use @@ROWCOUNT to loop through the rows but I really can't put it all together in a cohesive way.

I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table."
The 'sp' user I am connecting is the owner of the table. What could be the problem ?

Default Table Owner Using CREATE TABLE, INSERT, SELECT && DROP TABLE

Nov 21, 2006

For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.

Dbo.Table Of A Database In The .SQLEXPRESS Object Explorer: How To Copy The Dbo.Table To The Another Blank Dbo.Table?

Jan 9, 2008

Hi all,

The following dbo.Tables of Northwind.mdf in my .SQLEXPRESS (SQL Server Management Studio Express) are missing:
dbo.Categories
dbo.CustomerCustomerDemo
dbo.CustomerDemographics
dbo.Customers
dbo.Employees
dbo.EmployeeTerritories
dbo.Order Details
dbo.Orders
dbo.Products
dbo.Regions
dbo.Shippers
dbo.Suppliers
dbo.Territories.

But, I have these dbo.Tables in a different Database "xyzDatabase". How can I copy each of these dbo.Tables to the another blank dbo.Table of Northwind Database?

I right clicked on the dbo.Categories and I saw the following thing:
dbo.Categories
New Table...
Modify
Open Table
Script Table as |> CREATYE To |>
DROP To |>
SELECT To |>
INSERT To |> New Query Editor Window
File....
Clipboard
UPDATE To |>
DELETE to |>
From the above observation,I think it is possible to copy the dbo.Table from the one Database to the Northwind Database that needs to be repaired. Please help and advise me how to do this task or tell me where I can find the Microsoft document that gives the details of this X-copy thing.

Thanks in advance,
Scott Chang

P. S. I am using VB 2005 Express to create a project to learn "Calling Stored Procedures with ADO.NET" (see Paul Kimmel's article in http://www.developer.com/db/article.php/3438221) that needs the dbo.Tables of Northwind Database and my Northwind Database has been screwed up for quite a while and needs a big repair.

Newbie-DELETE A Record In A Table A That Is Related To Table B, And Table B Related To Table A

Mar 20, 2008

Hi thanks for looking at my question

Using sqlServer management studio 2005

My Tables are something like this:

--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]

-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]

--Foreign IDs = FID
--generated IDs = GID
Then I try a simple single row DELETE

DELETE FROM MyCompany.Employee
WHERE EmployeeGID= 39

Well this might look like a very basic error:
I get this Error after trying to delete something from Table ��Employee�?

The DELETE statement conflicted with the
REFERENCE constraint "FK_Branch_ManagerFID".
The conflict occurred in database "MyDatabase",
table "myCompany.Branch", column 'ManagerFID'.

Yes what I��ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a ��Branch�? entry, basically each entry in ��branch�? and ��Employee�? is child of each other which makes things more complicated.

My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use ��ON DELETE CASCADE�? or something?

Thanks
