Generating Unique Id Strings
May 25, 2004
Hi
I want to generate a unique record number in the following format
Company initials/year/Counter/RecordType (e.g. SDS/04/00123/WB)
Could someone recommend how I go about generating this number?
Should I create a separate table with columns for each section of the number and concantenate the columns in ID field of the actual table?
... or should I just create a stored procedure to generate the number each time?
... or should I do something completely different?
Regards
John :confused:

Hi,
I have the following tables :
Code Block
Create Table #Request ( [requestid] int , [customername] Varchar(30) , [stateno] nvarchar(5) , [cityno] int , Callid int, UniqueNo int);
Create Table #Call(Callid int,Calltype int,callDetailid int ) // CallType 1=New 2=Change 3=Delete
Create Table #CallDetail(callDetailId int,empid int)
The tables are populated in the following order: One row for CallDetail, One for Call and one for Request and so on
I have to generate a UniqueNo - Per empid, Per StateNo, Per CityNo, Per CallType and insert into #Request table along with the other data. How do I do this?
SAMPLE DATA
Code Block
Insert into #CallDetail(12123,1)
Insert into #CallDetail(53423,1)
Insert into #CallDetail(6532,1)
Insert into #CallDetail(62323,1)
Insert into #CallDetail(124235,1)
Insert into #CallDetail(65423,2)
Insert into #CallDetail(56234,2)
Insert into #CallDetail(2364,2)
Insert into #CallDetail(34364,2)
Insert into #CallDetail(85434,2)
Insert Into #Call(111,1,12123)
Insert Into #Call(112,1,53423)
Insert Into #Call(114,1,6532)
Insert Into #Call(123,2,62323)
Insert Into #Call(134,1,124235)
Insert Into #Call(143,2,65423)
Insert Into #Call(145,1,56234)
Insert Into #Call(154,2,2364)
Insert Into #Call(185,1,34364)
Insert Into #Call(195,1,85434)
Insert Into #request Values('324234','Jack','SA023',12,111,0);
Insert Into #request Values('223452','Tom','SA023',12,112,0);
Insert Into #request Values('456456','Bobby','SA024',12,114,0);
Insert Into #request Values('22322362','Guck','SA024',44,123,0);
Insert Into #request Values('22654392','Luck','SA023',12,134,0);
Insert Into #request Values('225652','Jim','SA055',67,143,0);
Insert Into #request Values('126756','Jasm','SA055',67,145,0);
Insert Into #request Values('786234','Chuck','SA055',67,154,0);
Insert Into #request Values('66234','Mutuk','SA059',72,185,0);
Insert Into #request Values('2232362','Buck','SA055',67,195,0);
EXPECTED OUTPUT will be (See the last column for unique nos). :
Code Block
Insert Into #request Values('324234','Jack','SA023',12,111,1);
Insert Into #request Values('223452','Tom','SA023',12,112,2);
Insert Into #request Values('456456','Bobby','SA024',12,143,1); // Calltype = 1 empid= 1, but state is different, hence unique id is 1
Insert Into #request Values('22322362','Guck','SA024',44,114,1);
Insert Into #request Values('22654392','Luck','SA023',12,123,3);
Insert Into #request Values('225652','Jim','SA055',67,143,1);
Insert Into #request Values('126756','Jasm','SA023',69,134,1);
Insert Into #request Values('786234','Chuck','SA023',72,145,2);
Insert Into #request Values('66234','Mutuk','SA059',72,185,1);
Insert Into #request Values('2232362','Buck','SA055',67,195,2);
Please note that this will not be run as a batch query, but the no. has to be generated and inserted into #record table in realtime. I have given bulk of records for understanding of the problem
Plz help. I am stuck from 2 days on this :

I have a whole bunch of bit fields in an SQL data base, which makes it a little messy to report on.
I thought a nice idea would be to assigne a text string/null value to each bit field and concatenate all of them into a result.
This is the basic logic goes soemthing like this:
select case new_accountant = 1 then 'acct/' end +
case new_advisor = 1 then 'adv/' end +
case new_attorney = 1 then 'atty/' end as String
from new_database
The output would be
Null, acct/, adv/, atty, acct/adv/, acct/atty/... acct/adv/atty/
So far, nothing I have tried has worked.
Any ideas?

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.

What's the difference in the effect of the followings:
CREATE UNIQUE NONCLUSTERED INDEX
and
ALTER TABLE dbo.titles ADD CONSTRAINT
titleind UNIQUE NONCLUSTERED
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?

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

Here is the table I created:
create table Test (
[recId] [int] identity(1, 1) not null,
[code] [varchar](50) not null,
[prime] [bit] not null constraint [DF_Test_prime] default (cast(0 as bit)),
constraint [PK_Test] primary key clustered
(
[recId]
) with fillfactor = 90 on [primary]
) on [primary]
go
insert into Test (code, prime) values ('AVA', cast(1 as bit))
insert into Test (code, prime) values ('BUS', cast(1 as bit))
insert into Test (code, prime) values ('BUS', cast(0 as bit))
insert into Test (code, prime) values ('BUS', cast(0 as bit))
insert into Test (code, prime) values ('CAR', cast(1 as bit))
insert into Test (code, prime) values ('CAR', cast(0 as bit))
insert into Test (code, prime) values ('RLW', cast(1 as bit))
insert into Test (code, prime) values ('RLW', cast(0 as bit))
insert into Test (code, prime) values ('RLW', cast(0 as bit))
select *
from Test
I need to create a constraint on this table that will not allow me to have two rows that are prime for the same code. So the following insert statement should fail:
-- This should fail
insert into Test (code, prime) values ('RLW', cast(1 as bit))
Thanks for you help!

hi,
I am developing a ASP.NET application using SQL Server as my database.
I want to create a number that is unique.
The number will have 8 digits.
first 2 digits correspond to year. ex:04 or 03
the next 6 digits start with 000001 and it should get added for each new entry of data.
i am not able to generate number in the way i said. I am relatively new to SQL. so any suggestions as how to go about solving the problem???. Are there any samples/codes available for this.
Any help would be highly appreciated.
thanks,

Hi all,
I have generated an SQL script such that when it is run, it will automatically create tables if not existing or drop the existing tables. The problem I have is that, is there any way I can also make the script create not only the tables but also transfer the data from the old database to the new database?
I would really appreciate if any of you could point me to any existing programs, scripts etc that can do that. Thanks in advance
Regards,
Celia

Is there a way to generate SQL Scripts from a stored procedure?
For disaster recovery and documenation reasons, we'd like to create scripts of our databases periodically. I, being somewhat lazy, would like to automate this so I really don't have to remember to run this every so often.
Any help would be appreciated.

ID Table A
1 Apples
2 Oranges
3 Grapes
4 Apricots
declare @TableB table ( seed numeric ,
)
insert @TableB
select 080513000448
union all select 080513000449
union all select 080513000450
Table B
seed
080513000448
080513000449
080513000450
I wrote the following query but i need generate a leading zero not sure which function can help maybe the right function but i am not sure how to use it in this case
SELECTconvert(varchar(10), getdate(), 12) +
(SELECT
CASE
WHEN SUBSTRING(ISNULL(max(seed),'00000'),1,6) = convert(varchar(10), getdate(), 12)
THEN SUBSTRING(ISNULL(max(seed),'00000'),7,12)
ELSE '000000'
END AS SEED
FROM B)
+ (row_number()
over (order by Id))
as SEED
FROM A
SEED
----
80513000451
The output which i need is
SEED
----
080513000451
rather then
SEED

Hi,
we would like to generate SSIS packages(connections, data flow tasks, etc..) programatically using C#. Is it possible to do so?
At present we are creating packages by dragging and dropping required componets from toolbox and configuring them manually. We have a requirement of creating around 300 packages every week. Manual creation of packages is really a nightmare.
I heard from one of friends that using c# we can create packages. is it true? if so, can we view/edit the packages generated using c# using VS 2005 IDE(if required) ?

I'm having problems generating the primary key for a sql server table. I use a slowly changing dimension to discriminate modified and new records. The primary key in the SQL Server table is a combo number/letter incremental (ex. 0000A, 0001A...9999A, 0000B...). I tried creating Instead of insert and For insert trigger for a table but this doesn't seem to do the work.
What are my other options? How can I generate a primary key for every new row?
Any advice is appreciated.

Hello all,
I have a few questions relating to scripts and I'm looking for some help, or at least a point in the right direction.
1) I'm generating CREATE scripts to move a number of tables/procedures/functions from my testing database to my production database. The issue I have is the script doesn't seem to be generated in a particular order, so I'm getting errors when a table/procedure/function is created that references something that hasn't been created yet. Is there a setting available to create the script in a specific order to prevent these errors?
2) This is somewhat related to the first question. I need to drop all the tables/procedures/functions before I re-create them. Can I set all the DROPs at the beginning of the script, and then run all the CREATEs?
3) Eventually the database will be ready for production and in use. And eventually I'll be asked to make changes, without erasing existing data. Can I accomplish this using the generate scripts feature? What topics should I be investigating when looking into conducting these types of updates? "Updating database" is too general and I'm not sure the technical term. I've done very simple DB-related tasks so I'm trying to figure out what I'm looking for so I can educate myself. Basically, I don't know what I don't know.
Any help is appreciated. Thanks.
