I am working on an ASP.net web application which inserts new record into an underlying table.
It is actually a ConfirmationNumber and should be unique. I have used abs(checksum(newid()))
For this purpose. Is there a better way to accomplice this?
Hi, all,
I have a question about adding a unique key column to an existing table.
what i trying to do is that: I have already created a table, now i wanna add a ID column to this table, and generate the values for ID column from 1 to the existing row number. How can I get this done?
Thanks a lot in advance for any guidance.
I have a data that with month values ranging from jan 2012 till july 2013 with some values associated with it.
I want to generate months automatically after july 2013 till december 2013 in sql something like the below one:
Is there a way in sql to do this?
Look at the following code,
Create table #test
(
id int primary key,
Name varchar(100)
)
insert into #test values (1,'John')
insert into #test values (2,'Walker')
[Code] ....
-- Query 1 :
update #test set name = 'Joney' where id = 1
-- Query 2 :
set rowcount 1
update #test set name = 'Joney' where id = 1
set rowcount 0
1. #test table have primary key & clustered index.
2. Obviously only one row will be available for an id.
3. In query 1, will the sql server look for matching rows even after it found 1 row?
4. Will query 2 really gains some performance?
This index is not unique

Hi Guys,
I am trying to insert a unique code, like a voucher code, into a table in MSSQL, 10 numbers (0-9) which obviously needs to be unique.
I can code this in ASP, but I think the process could be a bit long winded, i.e. create a key - run a stored procedure to see if it is free if not loop and check again. Surely there would be a way to do this in a stored procedure in one?
So the code would look like 3928492834.
1. Generate Key in SQL
2. Check if not used in column 'kcode' if it is, regenerate and check again.
Any advice would be greatly appreciated, I know how to do this in ASP but bit of a SQL newbie!
Thanks
John
Is there any way to auto generate the unique primary key when inserting data in MS SQL?
there is a way to create the increasing integer as primary key, but is there any ways other than that?
thank you

Hi
I am using sqlserver 2005 and want to generate unique numbers for all the records in a table using sql.
Something like table A has
Code:
FRUITS
-------------
Oranges
Mangoes
Apricots
....
I want to write a sql query that does something like
SELECT convert(varchar(8),getdate(),12)+'000001' my_number,
fruits
from table A
so the output is
[code]
my_number Fruits
080501000001 Oranges
080501000002 Mangoes
080501000003 Apricots
[code]
is there a way to do this without resorting to identity columns
Hy all,
I'm working on a final project for school. It is a warehouse application. For this application I will need to generate a barcode. I have read some articles online and found out that I could use the code 39 barcode font.
I just don't fully understand how to generate the unique barcode. Could someone please help me? I also would like to store the barcodes in a sql server table. Could I use reports to print the barcode?

I need to generate unique string Id from the range AAAAA to PZZZZ. This id will be unique for each Users for e.g.
User ---- TransactionNo ---- UniqueId
--------------------------------------------
12001 --- 101 --- AAAAA
12001 ---- 102 --- AAAAB
12001 --- 103 --- AAAAC
12001 ---- 104 --- AAAAD
13001 --- 105 --- AAAAA
13001 ---- 106 --- AAAAB
13001 --- 107 --- AAAAC
13001 ---- 108 --- AAAAD
more the records of each user, unique should be the ID as displayed above.. Optimized way to generate the same...
I need to generate a random 10 digit alphanumeric string that is also unique within a table. My application will be calling a stored procedure to insert this number into the table. This number will be associated with a id from another table. Is it better to generate the random number within sql (and perform the lookup at the same time), then just pass the number back to the calling application ?
If the calling application generates the number, it will also need to make a call to check if its unique. So im thinking it would be best to simply have sql generate this random number, check the number against the table and then insert the new record.
thoughts ?
[RS 2005]
Given the starting and stopping points (time values), how do I generate values between these points.
For example, if I have 08 (representing Hour) as a starting point and 12 as a stopping point.
From this I would like to generate a data sequence like 08, 09, 10, 11, and 12.
So how do I accomplish this? In SQL or in the RS?
The only thing I can think of is using a WHILE loop and a temporary table in SQL (not to keen on doing this).

Hi
I have a sql procedure. I need to create UNIQUE random 13 digit number to use for barcode.
How do I generate 13 digit UNIQUE random in sql procedure?
Advance thanks
I am trying to achieve the below problem statement, however I am getting stuck at the looping part.
EX: We have three columns
First Name | Last Name | Mothers Name
I want to generate the username field using above columns, so lets consider, I have following data
First Name | Last Name | Mothers Name
a b cdef
a b cdfg
a b cdfj
Expected Usernames:
1: a.b
2: a.b.c
3. a.b.cd
Basically, it has to be FirstName.LastName.(incremental letters from MothersName until the name becomes unique)
GENERATE 8 CHARACTER ALPHANUMERIC SEQUENCES
Requirements
• ALPHANUMERIC FORMAT – > AA00AA00………..ZZ99ZZ99
Last 8 bytes will alternate between 2 byte alpha/2 byte numeric
• Generate from Alphabets – A through Z Numbers -0 to 9
• Generate Unique Sequence (No Duplicates).
• Must Eliminate letters I and O
Output Expected
• AA00AA00………..ZZ99ZZ99
• Using 24 alphabets & 10 digits ,
24*24*10*10*24*24 = 3 317 760 000 records
Below is my Sql Function -
CREATE function [dbo].[SequenceComplexNEW]
(
@Id BIGINT
)
Returns char(8)
[Code] .....

What would be the best way to insert unique values into a table/unique column ?
I cannot make that table/unique column as indentity. Right now, I use a staging table with indentity column, insert rows then insert rows back to
final table.
Suggestions are much appreciated.

Hi,I have two tables such that in each table I need to make sure thatcolumn x in table A and column y in table B have a unique valuesmeaning that a user cannot insert a value to column A if its alreadyexist in column B and vice versa.How can I enforce it? Please remember that this two different tables.Thanks,Ori.
View 2 Replies View RelatedHi, I have been asked to write some code that can check a large table for duplicate values in a non pk column. The table may have up to 1000000 rows. The PK column is an auto increment field. For performance reasons the column in question could not be set to unique values only for inserts, an algorithm is used to create unique no's before the insert but what I am doing is double checking that their have been no duplicates created accidently. If their are duplicates I need to know what rows they occurred on.
Thanks
Hi,
Suppose a table [Inventory]:
Item Color Quantity
-------------------- -------------------- --------------------------
Table Blue 10
Table Red 20
Table Yellow 30
Chair Blue 40
Chair Red 50
I'm wondering if there is a group state like this:
Select Item, ?Function(Color), Sum(Quantity) From Inventory Group by Item
which returns this:
Table Blue,Red,Yellow 60
Chair Blue,Red 90
Does anyone has an idea how this can be achieved?

how to find all possible combinations of values, for example:
My table includes:
Code:
CREATE TABLE temp1 (item varchar(50), ORDER int);
INSERT INTO temp1 (item, order) VALUES ('apple',1);
INSERT INTO temp1 (item, order) VALUES ('pear',2);
INSERT INTO temp1 (item, order) VALUES ('blueberry',3);
I need the output to be like this:
apple
pear
blueberry
apple, pear
apple, blueberry
pear, blueberry
apple, pear, blueberry
I don't need the reverse of each. For example, I need only 'apple, pear'... I don't need 'pear, apple'.
I need a query to return two values. One will be the total units and the other will be total unique units. See exmaple data below. It does not have to be one query. This will be in SP, so I can keep it seperate if I have to.
ID | ID_UNIT
1 | 01
1 | 01
1 | 02
1 | 03
1 | 03
1 | 04
1 | 04
I need two results.
Total Units = 7 - easy to do by using count()
Total unique units = 4 - I cannot use group by as it would return multiple results for each unit, which is not what we want.
I am getting same value all over how to get unique values for each measures.
how to resolve it.
Hi All,
I need a bit of help with a join. I have 2 tables :
TradeSummary
has fields : SymbolID, CurrentPrice, TotalValue
Trades
has fields : SymbolID, TradeID, ExecutionTime, TradeValue
TradeSummary has one entry for each SymbolID, while Trades contains one or more entries per SymbolID
and what I want to retreive is :
For every item in TradeSummary get CurrentPrice, TotalValue from TradeSummary
and also get TradeValue from Trades for the record for max(ExecutionTime)
tables are joined on TradeSummary.SymbolID = Trades.SymbolID
Every attempt of mine so far returns multiple rows for each SymbolID - I want only one row per SymbolID
thanks in advance
I am using Access 2007 and I have 10 columns of data.
I am trying to select all the data from all 10 columns where the first column's data returns only the Unique values and the other columns return all the data from the row that is returned from the first column.
I have used this
SELECT DISTINCT [SFR Rates All].Sorter, [SFR Rates All].SProgram, [SFR Rates All].S_Price, [SFR Rates All].Min_Loan, [SFR Rates All].Max_Loan
FROM [SFR Rates All];
But that returns all the data in the table and all values in the Sorter column with duplicates because each row has distinct data.
I am trying to return unique values from [SFR Rates All].Sorter (the first column) and all the data from the other 9 columns that are contain the row with the unique value in Sorter.
I know that I am missing something basic but well, I can't figure it out.
Thanks

Hi I am using VS 2005 with SQL 2005.
I had a Datagrid and i Need to bind data into it.
I need to show Random Unique ID's based on the Parameter i pass.
I wrote select top 5 * from Employee order by NEWID()
for this i had created a Stored Procedure as
create Proc Demo(@N int)as beginselect top @N * from Employee order by NEWID()end
Its showing a syntax error near @N. How can i pass the parameter for Select Top @N * from .......
I am in a situation where I need to find out unique field names with different values in a table having 200+ columns.
Let's say I have two rows with 200+ columns ( I exported these rows from Lotus Notes to SQL Server) I am not sure what columns makes unique of these rows. It's going to be tedious by checking each column values.
Is there anyway I can write a squl query on these two rows which outputs column names which are having unique values.
I would appreciate If anybody gives me hint about achieving desired result
I have this query and it works except for I am getting duplicate primary keys with unique column value. I want to combine them so that I have one primary key, but keep all the columns. Example:
Key column 1 column 2 column 3 column 4
A 1 1
A 2 2
B 2 3
B 5 5
it should look like:
A 1 1 2 2
B 2 3 5 5
Here is my query:
SELECT *
FROM [TLC Inventory].dbo.['2014 new$']
WHERE [TLC Inventory].dbo.['2014 new$'].mis_key LIKE '2%'
AND dbo_Product_Info#description NOT LIKE 'NR%'
AND dbo_Line_Info#description NOT LIKE 'OBSOLETE%'
Do I use a sum function?
I have a table which maps two related IDs. That table has 3 columns: ID, BHID & EPID. I need to find all of the BHIDs where the EPID is unique. It seems easy enough, but I keep going in circles..
USE [CGB]
GO
/****** Object: Table [dbo].[ePID_BHID] Script Date: 04/15/2015 15:48:14 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

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

I have a data set as -
ID Set Date DB Date
100 Null 07/01/15
100 07/05/15 07/02/15
100 07/10/15 07/08/15
I want to able to get 2 unique dates
1. 07/02/15 - As I want the DB date for ID - 100 when set date changed from a null value to non null value.
2. 07/08/15 - As I want the DB date for ID - 100 when a non null set date changes.
The table has such records for lot of different ID's.
I'm trying to use merge data from a staging table to a production table. There are a lot of duplicate values for serverName and I only want to insert one instance where there are duplicates.
How I can adapt the code I have so far to achieve this?
MERGE tblServer AS TARGET
USING tblTemp AS SOURCE
ON (TARGET.serverName = SOURCE.serverName)
WHEN MATCHED THEN
UPDATE SET TARGET.serverName = SOURCE.serverName, TARGET.serverLocation = SOURCE.serverLocation
WHEN NOT MATCHED BY TARGET THEN
INSERT (serverName, serverLocation)
VALUES (SOURCE.serverName, SOURCE.serverLocation)
WHEN NOT MATCHED BY SOURCE THEN
DELETE;
