How To Auto-increment Primary Key When Adding A New Row Using Update Method?
Jul 26, 2007Hi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model)
2 {
3 //cannot have the same device entered twice!
4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1)
5 return false;
6
7 RepositoryDataSet.DevicesDataTable devices = new RepositoryDataSet.DevicesDataTable();
8 RepositoryDataSet.DevicesRow device = devices.NewDevicesRow();
9
10 device.make = make;
11 device.model = model;
12
13 devices.AddDevicesRow(device); << Error thrown Here!
14 int rows_affected = Adapter.Update(devices);
15
16 return rows_affected == 1;

Auto Incremented Integer Primary Keys Vs Varchar Primary Keys
Aug 13, 2007Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.

Dec 21, 2007Hi all,I have a table where I have my ProdPK set up as Primary key, turned on "Is Identity" and set the Identity increment to 1. But each time I add a new item, the number incremented by 2... I have couple of other tables and they are all fine, just this particular table increased twice as it should. I check the setting against other tables and everything seems to be the same. By the way, this is adding the data to the table inside MS SQL Server Management Studio manually. I haven't done anything in the ASP.NET page yet. Thank you very much,Kenny.

Apr 13, 2008Dear all,
I am using SQL express 2005 in visual studio 2008. I would like to use Form View to insert new record in the table. There is a column call "id". I think it is too stupid to let user enter a unique identifier instead of generating by the system.
I know how to generate a random integer number in a normal TextBox. However, when I edit the InsertItemTemplate, I cannot modified the value of that textbox. For example, i couldn't use "TextBox1.Text = temp;" here. How can I achieve to change this TextBox's value by the system that I would like to generate a random interger. Thanks a lot.

This table changes often, so just adding 1 to the last number used, will fast run out of numbers.
The table is accessed by many users, so it can not be manually generated.

Apr 26, 2007Ok - I have two tables that are relational. I have been inserted data into the tables because of testing. I also have been deleting data. My question is how do I reset the auto-incremented Primary key values.
For example:
Primary key of table one is bizID. Well there are only 3 record currently in the table. The bizIDs are 1-3. If I insert another record the bizID will be 88 because that was the next auto-incremented number. I obviously deleted the other records. I want to start the primary key value over from zero.

How can I do it? And if I'll add a new alpha character in the Primary Key field, for example DEF-0001, then I'll add another and it auto increments to 002, and so on, and it will go back to 0001 if i'll use another combination of alpha characters. for example, i'll add a new alpha character AAA, will it go back to 0001 or it will continue? T___T I hope u get my point..

Redefining An Auto-generated Primary Key Constraint Name
Jan 9, 2007Hey there :)I'm using Ruby on Rails to create a migration of a legacy database onan MS SQL Server. I'd like to name my constraints myself, such as'pk_authors', but in the cases where a table has an auto incrementedIDENTITY(1,1) id field, Rails takes over and adds the primary keyitself when creating the table.This is fine, except then the constraint gets a name like'PK__authors_384934' which is not very intuitive or easily remembered;)I'd like to just throw in an 'ALTER TABLE authors...' statement justafter that table has been created, but I'm not sure how to go aboutrenaming the auto generated constraint since the name it gets ispartially random. Is there any way to indirectly refer to theconstraint like 'RENAME PRIMARY KEY CONSTRAINT ON authors TOpk_authors' or something like that, so that I can rename theconstraint?Thanks in advance,Daniel Buus :)

Loop, Auto Update
Jun 16, 2008Hi,
I am back with some more questions.
The structure is something like this -
Table 1 - dbo.DimHC_Team - This stores TeamID and TeamName
Table 2 - dbo.DimHC_Team_Config - This has TeamID TeamDate (not really used anywhere) TeamHeadCount (Max strength of a team)
Table 3 - dbo.DimHC_Team_Agg - This has TeamID, Team_Date (1st of every month, so that when I see the data for past months I use these dates) , Permanent Employees, Contracted employees, Open positions, Total, HeadCount.
Now, I have a stored procedure which goes like this -
declare @datevar datetime
declare @datevar2 datetime
declare @datevar3 datetime
declare @datevar4 datetime
select @datevar = DATEADD(dd, -(Day(getdate()) -1) ,getdate())
select @datevar = dateadd(dd, datediff(d,0,@datevar),0)
select @datevar2 = Dateadd(m , 1 , @datevar)
select @datevar4 = Dateadd(dd , 9 , @datevar2)
select @datevar3 = dateadd(m,2,@datevar)
select @datevar3 = dateadd(dd, -2 , @datevar3)
if (not exists (select * from dbo.DimHC_Team_Agg where Team_Date = @datevar2))
begin
insert into dbo.DimHC_Team_Agg
(TeamID, Team_Date)
select TeamID , @datevar2 from dbo.DimHC_Team_Config
end
update dbo.DimHC_Team_Agg
set Team_Head_Count = dbo.DimHC_Team_Config.Team_Head_Count
from dbo.DimHC_Team_Config, dbo.DimHC_Team_Agg
where dbo.DimHC_Team_Agg.Team_Date = @datevar2
and dbo.DimHC_Team_Config.TeamID = dbo.DimHC_Team_Agg.TeamID
update dbo.DimHC_Team_Agg
set
Perm_Posn = (select count(EmpType) from dbo.uview_DimHC_Emp_view1
where EmpStartDate < = @datevar4 and EmpType = 'Permanent'
and (EmpEndDate = '01/01/1753' or EmpEndDate > @datevar3)
and TeamID = '1'),
Contract_Posn = (select count(EmpType) from dbo.uview_DimHC_Emp_view1
where EmpStartDate < = @datevar4 and EmpType = 'Contractor'
and (EmpEndDate = '01/01/1753' or EmpEndDate > @datevar3)
and TeamID = '1')
......
What this block is doing is converting today's date to the first of this month. Going one month and 2 months in advance. Then it checks if any employee's start date < 10th of the next month and end date > 31st of the next month and if both the conditions are met then increments the employee count for that team as 1.
This TeamID is then repeated for 13 teams that I have right now. So that every month I will run it and it will update.
Now, I have 2 problems - First being that I had to write this block for 13 teams which isn't really a smart thing to do. Let's say I add a team tomorrow then I will need to modify this stored procedure and then tomorrow I may not be here, so the person who uses it should be able to do it easily. So, I wanted to know if I can loop or something through this with the max limit of TeamID coming from some external source and not like fix it to 20 or something.
Second, let's say in the beginning of this month I add a new team. The way I will do it is I will add it to dbo.DimHC_Team and dbo.DimHC_Team_Config table. Now, if I run this stored procedure then
if (not exists (select * from dbo.DimHC_Team_Agg where Team_Date = @datevar2))
is not going to return NULL as there will be entries with some teams right now. So this new Team won't be inserted in the dbo.DimHC_Team_Agg table and I will have to manually do it.
Can somebody help me as to how can I get over with these two problems?
Sorry for being really long but I thought it best to give all the details.

Auto Update To Sql Server Tables
Oct 22, 2004I'm changing data storage for an asp.net project from MS Access to Sql Server. I've got the web site working, but I need to update the sql server tables with data from our Oracle db daily. What is the "best" way to do that?
I've read about DTS, but have never done anything like that. Would it be worth the time and effort to study? (So far I've created a package, with the import wizard, that doesn't work & I don't have the authority to delete :-)
I know I could create a dataset with my Oracle data and use that to update sql server. But is there a way to schedule an aspx to run authomatically? Would this affect performance? The sql server db isn't very big (30-40,000 records), but the Oracle db is & I need to do quite a bit of manipulation to the data.
This is new to me & I'm don't know what I should be searching for to find help. And if there is a more appropriate place to post this question, please let me know.
Thanks.

Concern On Auto Update Statistics
Dec 7, 2007Hi all,
We are using SQL Server 2005. The auto update statistics and auto create statistics for a database is set to ON. This database has a very heavy work load. When I checked the individual statitics , still the last updated statistics is in a old date value (few months ago).
Is it necessary to manually update the statistics for the same database? Or can we rely upon "auto update statistics" itself ?
Usually in what frequency the manual UPDATE STATISTICS should be run on production system which has heavy transactions ?
Thanks & Regards,

Auto Update Stats Causing Blocking
Mar 10, 2003Recently a production server suffered a critical blocking period and I wanted to know if I could solicit some input. It seems that a stored procedure was in the middle of recompiling while and auto update statistics started. This caused blocking for like an hour on the
single object (stored procedure) that was originally called. The table that the update occurred on and that the
stored procedure is reading form is quite large. It is 2 mil rows and about 140 columns wide. Some info from
sysprocesses is below. The table alone takes up almost 4GB of space, when looking at sp_spaceused. I have some
questions.
1. Can the update statistics for a '_WA%' stats cause
blocking on a table?
2. Does an update stats on an index survive a restart of
SQL server? We tried restarting, but the blocking did not
end.
3. If the stored procedure is running under a compile, can
the server automatically start an update stats and cause
the stored procedure to wait?
4. Can the server automatically start an update stats on
more than one column stats at a time, causing one to be
blocked by the other?
5. We had never seen this issue before going to SQL2K
clustering. Is this something specific to SQL2K and not
SQL7 ?
Thanks for your input.
