Unique Fields In SQL Server Tables
Oct 12, 2006
I feel sure that this is a very naive question, but it is freeky me out that I can solve it.
With SQL server what is the easiest way to make a field other than the Primary key unique?
Would appreciate help with this.
Thanks

I have two tables in my database called CartItems and OrderItems. Istore all of a session's shopping cart items in the CartItems tableusing the sessionID as the identifier (called cartID in my DB). Afteran order is placed and is approved, I would like to copy all of theitems in the CartItems table for that given cartID to the OrderItemstable given a new orderID.I will know the cartID and orderID ahead of time and would like tosend them both into a stored procedure and have the transfer takeplace.Example:take this data...CartItems (table)--------------------------------------cartID | itemID | quantity | price--------------------------------------12345 2 1 12.9512345 7 2 17.95and make it this data...OrderItems (table)--------------------------------------orderID | itemID | quantity | price--------------------------------------00001 2 1 12.9500001 7 2 17.95via some stored procedure that I send (@cartID,@orderID)Any help would be greatly appreciated!!

How can I create a Table whose one field will be 'tableid INT IDENTITY(1,1)' and other fields will be the fields from the table "ashu".
can this be possible in SQL Server without explicitly writing the"ashu" table's fields name.

Table Name: Denominator
Already has the following constraint:
PK_Denominatorclustered, unique, primary key located on PRIMARY DenominatorID
How can I add a unique key that will cover the 3 fields --> MemberID,MeasureID,TimePeriodID
I also want to know whether we can include the " WITH ( IGNORE_DUP_KEY=ON ) "

I want to add a unique constraint on 3 fields, to only allow the value in the field ONE time. The value will NEVER be the same for anything else. This is the table structure
Code:
Create Table Employees
(
P_Id int NOT NULL,
InstructorName varchar(255) NOT NULL,
CourseName varchar(100) NOT NULL,
DataTableName varchar(100) NOT NULL
)
I want to create a unique constraint across the fields Instructorname, CourseName, DataTableName as their is ONLY 1 instructor per course per table so those 3 fields will ALWAYS hold unique values. I think the constraint syntax would go like so, but want to check before I go butchering some sql syntax.
constraint syntax:
Code:
Alter Table Employees
Contstraint uniqueEmployee Unique (InstructorName ,CourseName ,DataTableName )

I'm designing an app for stock keeping. In my DB, I have a field called "ItemSerialNo" and I made it unique(but not the table's primary key). On my front end, I have a text box for Item Serial No and a combo box loaded with the item brands and also a save button. I know that if I try to save a serial no already existing in my DB, the app won't allow me because of the unique property of the field named "ItemSerialNo". But I want to be able to save a serial no already existing in my DB but with a different brand name.
For example, I want to be able to save information like:
1. ITEM SERIAL NO = 12345
BRAND NAME = AA
2. ITEM SERIAL NO = 12345
BRAND NAME = BB.

What I need to do is re-populate a unique number into multiple fields,
Let me explain, An employee can appear in the first table only once but can be in the second table multiple times with multiple employee numbers .There is a field called TFN that is unique and we are using it to create a unique id called KRid so what I have done is created 2 tables namely TEST_TBL and TEST2_TBL . In TEST_TBL I am populating a KRid with a unique no being produced by the TFN field only once i.e 12345 being the resulting unique id number. If an employee has 2 employee numbers i.e empno 1 and empno 1000,only employee no 1 will have the unique KRid created but nothing for 1000 because the record already exists , so what has me stumped is that the TFN for employee empno 1 and the TFN for empno 1000 are the same. How do I get the KRid (12345 from empno 1) to populate empno 1000 in TEST2_TBL , The second table has all records in so I can group the second table by TFN id but how do I populate employee 1000 in the second table with the KRid 12345.
Please help!!!!! Below are how the tables are set up and an example of the result.
TABLE 1
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST_TBL]

GO
TABLE 2
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TEST2_TBL]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[TEST2_TBL]
GO

Query goes as follows for table 1:
SELECT NPE000.EmpNumber, NPET00.RecordStatus, NPE000.KR_ID, NPE000.Surname, NPE000.FirstName, NPE000.SecondName, NPE000.Class, NPE000.DateEmployed, NPE000.DateOfBirth, NPE000.HoursPerDay, NPE000.HoursPerWeek, NPE000.PassportNo, NPE000.AwardCode, NPE000.EmailPayslipTo, NPE000.Location, NPE000.Grade, NPE000.DateTerminated, NPE000.EmploymentType, NPE000.DistCode, NPE000.EmpStatus, NPET00.TaxRefNo FROM NPE000 NPE000, NPET00 NPET00 WHERE NPET00.RecordStatus = 0 and NPET00.TaxRefNo <> ' 111111111' and NPET00.TaxRefNo <> ' 000000000' AND LENGTH(NPET00.TaxRefNo) >= 9 AND LENGTH(NPE000.KR_ID) >= 0 AND NPE000.EmpNumber = NPET00.EmpNumber
Query goes as follows for table 2:
SELECT NPE000.EmpNumber, NPE000.FirstName, NPE000.Surname, NPE000.Class, NPE000.Location, NPE000.EmploymentType, NPE000.EmpStatus, NPET00.TaxRefNo, NPE000.Paypoint, NPE000.KR_ID, FROM NPE000, NPET00 WHERE Recordstatus = 0 and (EmploymentType = 1 AND EmpStatus = 1 AND NPE000.EmpNumber = NPET00.EmpNumber
From this you can see that in table 1 it will only create 1 KR_ID for only one employee number but in table 2 I am bringing through all employee records. In table 2 I can group by NPET00.TaxRefNo which will bring all NPET00.TaxRefNo's togeather. From that I would like to populate the other employee numbers with the unique KR_ID.
Example:Table 1
000001,Jackson,James,Sam,7.6,38,12345,475431212
Example:Table 2
000001,Jackson,James,Sam,7.6,38,12345,475431212
001000,Jackson,James,Sam,7.6,38,,475431212
I hope this helps
Thanks in advance

I have a simple query which displays items from inventory with their latest annual test date. I want to create another unique reference in my results to use as a certificate number. The number should be a combination of the item+month+year from the test date. What is the easiest way to accomplish this?
My query and my desired results are below:
select item, test_date
from inventory
where cat = 'TELE' and itemised_status > 15

I am working on creating a report which is retrieving data from a SQL 2005 database and being displayed in a C#.net web page. Presently, I am binding the dataset to a ASP:Gridview on the web page.
I am currently retrieving most of the needed fields using the following SQL statement:PROCEDURE [dbo].[pr_getReportTickets] @DateCreated nvarchar(15) ASBEGIN
-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
-- Insert statements for procedure hereSELECT tbl_Queue.num_TicketNumber AS TicketID , tbl_Users.str_Name AS Technician , tbl_Queue.str_QueueLocator AS TechNTID , tbl_Queue.dat_ReceivedRequest AS dateCreated , tbl_Queue.dat_DueDate AS DueDate , tbl_Queue.str_TaskName AS TicketTitle , tbl_Queue.str_Requestor AS RequestorNTID --, I need most current dat_TimeStamp from tbl_Notes here for this record --, I need most current int_PercentComplete from tbl_Notes here for this record --, I need to sum up all of int_MinutesWorked fields from tbl_Notes here for this record , MasterEmp.dbo.fn_FormatFullName(tbl_employee.str_fname, tbl_employee.str_lname) AS RequestorName , tbl_Queue.str_TicketType AS TicketType , tbl_Status.str_TaskStatus AS TicketStatus , tbl_Severity.str_Priority , tbl_Complexity.str_Complexity , tbl_Severity.str_Priority + N' / ' + tbl_Complexity.str_Complexity AS Priority , tbl_Queue.dat_CompleteDate as DateCompleted
FROM dbo.tbl_Queue LEFT OUTER JOIN MasterEmp.dbo.tbl_employee AS tbl_employee ON dbo.tbl_Queue.str_Requestor = tbl_employee.str_ntid LEFT OUTER JOIN tbl_Users ON tbl_Queue.str_QueueLocator = tbl_Users.str_ntid LEFT OUTER JOIN tbl_Status ON tbl_Queue.num_Status_CD = tbl_Status.num_Status_CD LEFT OUTER JOIN tbl_Severity ON tbl_Queue.str_Severity = tbl_Severity.str_Severity LEFT OUTER JOIN tbl_Complexity ON tbl_Queue.int_ComplexID = tbl_Complexity.int_ComplexID
WHERE (dbo.tbl_Queue.dat_ReceivedRequest > CONVERT(DATETIME, @DateCreated, 102))
ORDER BY TicketType, tbl_Queue.str_Severity
I also have another table called tbl_Notes. This table contains an unlimited quantity of records for every “num_TicketNumber�. This table contains the following fields: num_TicketNumber, str_TechRep, str_Notes, dat_TimeStamp, int_PercentComplete and int_MinutesWorked
I need to add two more fields to the query, but I do not know how to tell the SQL statement how to retrieve the data for the specfic record and inbed the fields into the Dataset being returned from the database to the web page.1) The first field I need is the most current recorded Date field from the tbl_Notes table for the each of the records returned in the above SQL statement. Similar to: SELECT TOP (1) dat_TimeStamp FROM tbl_Notes WHERE(num_TicketNumber = xxxx) ORDER BY dat_TimeStamp DESC2) The other field I need to return with the Dataset is the sum of the int_MinutesWorked for each of the tickets being retrieved. Similar to: SELECT SUM(int_MinutesWorked) AS TotalMinutesFROM tbl_Notes WHERE (num_TicketNumber = 49)

May be we may do by dense_rank or Row_Number, but I couldn't get the exact query to produce based on the above table values. Â There are some duplicates in the table(which are not duplicates as per the Business). For those duplicated Unique ID should be same(Marked in Orange Color which are duplicates).Â

I have Database Library, which has a lot of tables and we need 3 tables for quary:
Table Librarians: field ID, field Surname;
Table StudentCard: field ID, foreign key on table Librarians and other fields, which we don't use
Table TeacherCard: field ID, foreign key on table Librarians and other fields, which we don't use
Query: Select the librarian's surname, which gave the most count of books.
I know, how to resolve, when i took datas only from one table, e. g. TeacherCard
SELECT TOP 1 WITH TIES Librarians.LastName, MAX(Librarians.CountOfBooks) AS Books FROM
(SELECT L.LastName, COUNT(*) AS CountOfBooks FROM Libs L, T_Cards T
WHERE T.Id_Lib IN (SELECT L.Id)
GROUP BY L.LastName) AS Librarians
GROUP BY Librarians.LastName
ORDER BY MAX(Librarians.CountOfBooks) DESC
GO
I dont know, how to use datas from TeacherCard and from StudetnCard at the same time.

Doing a data migration from one CRM to another and need to get a listing of all entities in current CRM, together with fields and field types. OK, I got the XRMToolBox which gives me that, but I'm hoping there is a sql tool out there that will do the same, plus give me a count on each field of the number of entries in that field in the database.

Hi!
I'm not sure how to resolve this problem:
I've got 4 tables:
- Table1 (UniqueCode, Col11, .. , Col1N)
- Table2 (UniqueCode, Col21, .. , Col2M)
- Table3 (UniqueCode, Col31, .. , Col3X)
- Table4 (UniqueCode, Col41, .. , Col4X)
Each TableX has the same column: UniqueCode and its column's value can't be duplicated in the tables.
Ex.
Insert Table1 Values ('Code1', 'Ex1', ... )
Insert Table2 Values ('Code1', 'Ex2', ... ) -> Error!
1) Should I control this programming a Trigger?
2) Would be better to do a new Table?
TableUnique( UniqueCode, IdTable1, IdTable2, IdTable3, IdTable4)
.. for example??
Thanks!!!

Fourhistory table maintains 4 columns as part of history with the use of effectivestart and end dates. Here history capturing is at day level.
Desired Result: I want to merge the status column into FourHistory table.Below i have given some possible sample scenarios which i face and the third table contains the expected ouput.how to achieve this in T-SQL query.

hi guys,
i have 3 tables (T1, T2, T3), each with the same structure:
ID1 -> char(10)
ID2 -> char(12) NULL
ID3 -> char(10)
Value1 -> money
Value2 -> money
Value3 -> money
Note1 -> Text
Note2 -> Text
ID1+ID2+ID3 is the clusterd unique key in each table
what i want:
ID1, ID2, ID3 (with distinct occurencies of all 3 tables), T1.Value2, T2.Value2, T2.Value3, T3.Value1, T3.Note1
what i tried is to get all possible rows with
SELECT ID1,ID2,ID3 FROM T1
UNION
SELECT ID1,ID2,ID3 FROM T2
UNION
SELECT ID1,ID2,ID3 FROM T3
but i dont know how to join or add the other columns. maybe with
WITH RowList (ID1,ID2,ID3) AS ( ... code above.... ) SELECT ...
any ideas?
thx

Hello,
I am working with a database that among other things uses multipart keys as the unique indexes which are not consistent from say one table where a parent record resides to another table which contains related child records. For example I am working with two tables right now, one that contains content that I'll call Contents and the other which contains Usage information about the contents (number of view, a rating and comments give by a customer) which I'll call ContentsUsage. The system that manages the data for the tables has a versioning system by which, whn a content item is added (first time) a "unique" id (guid) and a version number of 1 is created along with the rest of data items in the Contents table and likewise in the ContentsUsage table (essentially a one to one mapping) on the like named fields in that table. Now, each time a given record in the Contents table is updated a new version, with the same guid is created in the Contents and ContentsUsage table. So one side I have:ContentGUID > AAAAVersion > 1ContentGUID > AAAAVersion > 2And the other table (ContentsUsage)ContentGUID > AAAAVersion > 1ContentGUID > AAAAVersion > 2
While both of these tables have a quasi-unique record (row_id) of type char and stored as a guid neither obviously are the same in the two tables and having reviewed the database columns for these tables I find that the official unique key's for these tables are different (table 1, Contents combines the ContentGUID and Version) as the composite / mutli-key index, while table ContentsUsage uses the RowGUID as it's unique index.
Contents RowGUID (unique key)ContentGUIDVersionViewsRatingComments................RowGUID ContentGUID (unique key)Version (unique key)Description.....
Bearing this in mind I am unable of course to link directly the two tables by using the just the ContentGUID and have to combine the additional Version to I believe obtain the actual "unique" record in question. The question is in terms of writing queries, what would the most efficient query be? What would be the best way to join the two in a query? And are there any pitfalls with the current design that you can see with the way this database (or specifically these tables are defined)? It's something I inherited, so fire away at will on the critique. Having my druthers I would have designed these tables using a unique key of type int that was autogenerated by the database.
Any advice, thoughts or comments would be helpful.
Thanks,P.

I have a procedure which updates a sequence number in a table such as the one below.
Seq Sequence_Id
------ ------------------
NextNum 1
This is the procedure ...
create procedure DBO.MIG_SYS_NEXTVAL(@sequence varchar(10), @sequence_id int)
as
begin
update mig_sys_sequences
set
@sequence_id = sequence_id = sequence_id + 1
where
seq = 'CSN'
return(@sequence_id)
end
The purpose of this is to generate a sequential number each time the procedure is called. This number would then be used in a number of different tables to allocate a unique id so that the id is unique across the different tables.
1). What is the most efficient way of allocating these unique ids? The tables that I plan to update will already be populated with data.
2). How would I call the above procedure from an UPDATE statement?
Many thanks,
Fred

Hi
I am trying to insert values into a table that doesn't exist there yet from another table, my problem is that because it is joined to the other table it keeps on selecting more values that i don't want.
Code Snippet
SET NOCOUNT ON
INSERT INTO _MemberProfileLookupValues (MemberID, OptionID, ValueID)
SELECT M.MemberID, '6', CASE M.MaritalStatusID WHEN 1 THEN '7'
WHEN 2 THEN '8'
WHEN 3 THEN '9'
WHEN 4 THEN '10'
END
FROM Members M
INNER JOIN _MemberProfileLookupValues ML
ON M.MemberID = ML.MemberID
WHERE M.Active = 1
AND OptionID <> 6
When i execute that code it returns all the values, let say OptionID = 3 is smoking already exists in the MemberProfileLookupValues table then it is going to select that persons memberID
I want to insert only members values that aren't already in the _MemberProfileLookupValues from the Members table (I think that it is because of the join statement that is in my code, but i don't know how i am going to select members that aren't in the table, because i have a few other queries that are very similar that are inserting different values, so ultimately
ONLY INSERT THE MemberID the values 6 and the statusID of X if it is not in the table already.
Any ideas / help will be greatly appreciated. Please help.
Kind Regards

SSIS 2005
Ok, I have a task in SSIS that does the following and works:
1) Brings in a txt file
2) Using a conditional component, checks for a value in the row.
3) Based on the value, splits the row into one of 3 tables (Header, Maintenance, or Payment)
Here is a print screen of what I have so far which splits Header rows into it's own table, Maintenance rows into its own table, and Payment Rows into its own table:
http://www.webfound.net/qst_how_to_add_header_PK_and_FKs.JPG
Here is a print screen of the conditional split:
http://www.webfound.net/conditional_split.jpg
Please take a look at the txt file here before it's processed:
http://www.webfound.net/split.txt
http://www.webfound.net/rows.jpg
Notice that the pattern is a header row, followed by it's corresponding detail rows. The detail rows are either Maintenance or Payment rows.
I need to somehow during the Script component or some other way, to assign a unique HeaderID (PK) to each of the header rows and add that ID to it's corresponding Maintenance and Payment detail rows in their corresponding tables as a PK. The problem is
1) I don't know how to do this in the flow of the components as I have it now
2) How do I tell it to create a new Header ID and Header FKs for the detail rows based off of each new Header row?
In the end (much later on in my entire package), the goal is to be able to run a stored proc to join and select the Header and Details rows back into a final table so I can then do more processing such as split each header and detail rows into their own txt files, etc....I don't need to go into details why but just know that this is the goal, therefore I need to relate each header row with their corresponding detail rows that are split off into a MaintenanceRow and PaymentRowTable

Hi all,
I'm not sure how easy of a task this is, or how to go about it, so I thought I'd ask here. I am doing a major overhaul to my site and am re-programming the backend which involves re-formatting my tables, table names etc.
What I want to do is set up a new table in the format I want for the new site, but still be able to have the live data that is being submitted to the site now, be entered into the new table so that I don't have to shut down the site for days to transfer and reformat data. Example
CURRENT SITE

Field1: Name
Field2: Address
NEW SITE
Table 1
Field1: Name
Field2: myAddress
Field3: City
I want to be able to somehow map the two together so that when data is entered into the Name field on the current site, that same name is also inserted into the new site table as well. Mapping like this:
(current site)Name -> (new site)Name
(current site)Address -> (new site)myAddress
The city field would be left unaffected as that data would only be entered once the new site is up and running.
I know I could do this from a stored procedure on the exiting site or by re-writting all of my SQL to insert into both tables, but right now all of the SQL is hardcoded into the pages and I have A LOT of pages. Is there a way to map the tables together from within SQL Server?
Cheers,
Jeff

Hi All,
I need to get the names of tables and fields (or atleast the fields) from a database. Is there a query I can use that will return what all the db's tables and those tables fields are?
Thanks
Lee

Hi,
I have a database with approx 95 tables. I would like to get a printout of each table, the fields contained therein and the field type
(i.e the information displayed when rightclicking a table in Enterprise Manager and selecting Properties).
I have tried to use the diagram function but due to the large number of tables the diagram is very complex and would have to be printed out on a huge sheet of paper to make it legible. I have also looked at the SP_HELP stored procedure but can't seem to get the syntax correct to display properties on all tables (info on one table is no problem).
Any ideas ?
Thanks,
Tim H

I am working with the article that MAK wrote on SecurityLogs http://www.databasejournal.com/features/mssql/article.php/3515886
I have completed this, but I have made some changes to the database (for normalization to 3NF purposes). I now have problems with a query.
I am trying to "Insert a new record in a table if it does not already exist in the table". To try to clarify I perform the following query:
INSERT INTO Tmp_Event
SELECT DISTINCT EventID, EventType, EventTypeName from Tmp
Which gives me the Tmp_Event table consisting of EventID's etc. (no duplicates). What I then want to do, is compare the 'Tmp_event' table and an already existing 'Event' table. These two tables are in fact identical. I would like to insert any records from 'Tmp_Event' into 'Event' if they do not already exist in 'Event'.
This query gives me all records that do not exist in 'Event'
SELECT EventID, EventType, EventTYpeName from Tmp_Event
WHERE EventID NOT IN (SELECT EventID from Event)
How can I change this query into performing an INSERT INTO Event as well?
Hope this makes sense :)

If possible, I would like to create a view using two different tables, but with the fields merged (ie. create one table from two tables). The table structures are pretty much the same. Can you do this from a singe SQL statement? Any ideas? My only alternative is creating a temp file that inserts records from both tables, but I want to avoid doing that.

Folks, i have to create four fields in every user table within my database:
CREATED_BY VARCHAR(25), CREATED_DATE [DATETIME], MODIFIED_BY VARCHAR(25), MODIFIED_DATE [DATETIME]
There are more than hundred tables, so i wanna automate this. i am tryin to do this in a cursor: please guide!
declare @name VARCHAR (50)
declare cur cursor
fast_forward
for select name from sysobjects where type='u' and status not like '-%'
open cur
WHILE (1=1)
BEGIN
FETCH NEXT
FROM cur
INTO @name
IF @@fetch_status = 0
BEGIN
ALTER TABLE @name
ADD created_by [VARCHAR] (25)
GO
ALTER TABLE @name
ADD created_by [VARCHAR] (25)
GO
ALTER TABLE @name
ADD created_date [DATETIME]
GO
ALTER TABLE @name
ADD modified_by [VARCHAR] (25)
GO
ALTER TABLE @name
ADD modified_date [DATETIME]
END
ELSE
BREAK
END
DEALLOCATE cur
I also want that if one column for a table exists; the other columns should be created rather than it quits.
Howdy!
