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?
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

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?
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 ?
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)
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.
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 ,

Hi all,
I'm using a free barcode font so i can create scannable tickets via reporting services 2k5. When I print the tickets, everything seems fine. But when i export to PDF though, it looks like the barcode font shrunk. All the lines are pulled together, making scanning impossible. Is there a certain setting or so that i can use to ensure the font's width ?
-Update-
The weird thing is: when i export it inside visual studio, the barcode is shown as it is supposed to in the pdf !?
Thanks in advance!
I am having an issue exporting a Code 39 barcode to pdf (works fine on RS and excel). Once in pdf it inserts white spaces between the bars to make it unreconizable. I have tried resizing, repositioning and different font sizes. SSRS and SQL are running on Windows Server 2003 Standard Edition Service Pack 1. Is there a hotfix out there for exporting EMF's to pdf's?

hi friends
i am new to working in crystal reports in my application i want to display barcode in crystal reports.
i was totally confused in this. can u help me..........
Hello all. I need to build a barcode and stuff it in a image control at runtime in SRS. I have the code at it works perfect for webforms etc but not in the actual SRS report itself. In SRS I put the code in the report properties code but it blows up on bitmap, graphics etc so I added the system.drawing and system.drawing.imaging namespace and it still fails with the same error. I'm certain there is a simple fix for this and would greatly appreciate anyones assistance in making this happen.

I am trying to encode the barcode on the reporting service using SQL server 2005, they told me it is possible to maintain the barcode on exported excel sheet, however, I did not find the barcode on it, only squre black image.
View 2 Replies View RelatedHi there,
Ok, so I have a report that is generating product labels on a standard mailing lable sheet (30 of them on a 8.5X11 sheet of stock). The whole process works just fine even the printing of the bar codes when I am printing the lables from VS2005's Preview function. However, when I moved the report to our reports server and run the same report, the barcodes don't print out. I have checked, and the barcode font has been installed on the server.
Any suggestions would be greatly appreciated. Thanks! - Eric-

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?
Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?
Which one do one use ?
thanks

BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?

hi team,
.Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code
Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword
and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
Thank You

Hi!
When MS published starter kits there were files .sql in App_Data. This files contained some sample data for a DB. How to create such files when I have database with data ?
Jarod
how generate an xml file from data in sqlserver2005
and read it in sql again
One of my first tasks on my current project was to generate all of the SQL scripts needed to rebuild the database. Of course, one of the catches was that everything needed to be separated out (table columns in different script from PKs different from FKs different from DEFAULTs, etc., etc.). And we wanted our own comment block inserted. So, I couldn't just use the Generate SQL Script from Enterprise Manager and be done with it. I was going to need to do some more work. Well, here's one of the scripts I wrote to build the FK scripts. Execute this script, then copy & paste the results into a new window. Break apart into separate .sql files as desired.
NOTE: Be sure to show results in Text (not grid) and change the display options in QA to return more than just 256 characters.
