I am using the Server Explorer in VS2005. I have created an additional field in a small test table with 3 other fields. The new field called foo_key does not show up when I query the table ( it has 7 records ).
I have some tables that I'd like to insert an auto-incrementing integer primary key. But at this point I cant figure out what's wrong. I have toggled the field as primary key on and off.It seems if I create a new table, then I see the primary key field and its autoincrementing as desired.
Could it be that I cannot add such a field if my table already has some records ? ...and to get one in would mean rebuilding a new table and shifting the records....pls advise

may i convert Composite Primary key into simple primary key in thr table like this.
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.
We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?
CREATE TABLE [dbo].[property_instance] ( [property_instance_id] [int] IDENTITY (1, 1) NOT NULL , [application_id] [int] NOT NULL , [owner_id] [nvarchar] (100) NOT NULL , [property_id] [int] NOT NULL , [owner_type_id] [int] NOT NULL , [property_value] [ntext] NOT NULL , [date_created] [datetime] NOT NULL , [date_modified] [datetime] NULL )
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance - property_instance_id will never be a foreign key into another table - queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row - Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
SELECT sysjobs.name, sysjobservers.last_run_outcome, CONVERT(varchar(8), sysjobservers.last_run_date, 112) AS LastRunDate, CONVERT(varchar(8), sysjobservers.last_run_time, 8) AS LastRunTime, GETDATE() AS CurrentDateTime FROM sysjobs LEFT OUTER JOIN sysjobservers ON sysjobs.job_id = sysjobservers.job_id WHERE (sysjobservers.last_run_outcome = 0) AND (CONVERT(varchar(8), sysjobservers.last_run_date, 112) >= DATEADD(day, - 1, GETDATE()))
I am wanting a similar solution, I need to convert an "int" to a time format, when I use this where ">= DATEADD(minute, - 720, GETDATE())" for the last_run_time I get this error:
Syntax error converting datetime from character string.
I have two tbls joined via a varchar field.. which in tbl I have to use a CASE statement to format it correctly for the JOIN..
All works well.. however, if I add a WHERE clause to the statement, with the WHERE clause affecting only one of the JOINED tbls.. All the NULLS are not shown.
I should get results like:
Postcode Count
tf4 0 tf5 23 tf6 15 tf7 0 etc
Whereas, when I add the where clause, none of the "zeros" are shown, so I get:
tf5 23 tf6 15
Why is this?

I modified something on the package, saved it and click on build. When i ran the package, it hit an error. when i saw the object that has an error, it was the one i modified. my changes were not applied. i stopped the runtime. and double click again on that package, it reflected my changes. why during runtime it's showing the old version? what's the proper way of saving the package and building it? What's the different of Build and Rebuild?

The query should take all of the UK postcode regions (districts) and then match them up to the postcodes in a customer tbl...
What I'm trying to show is the count for postcode resutls, even the postcodes where there are no customers.

how can i show the values of my database in for example texbox.can u give me some simple code on how to connect to my SQldatabase server express? and how i can retrieve the file?thnx
Here is my code. Basically what I am doing is selecting from the database based on the current user. The ReaderResults.Text label is not showing the info pulled from the database, and the ReaderError.Text label is not showing an error. I also tried putting the ReaderResults.Text label inside the loop and that didnt work. Any suggestions? 'Database ConnectionDim con As New SqlConnection("Data Source = .SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|ASPNETDB.mdf;user instance=true")Dim currentUserID currentUserID = Context.User.Identity.Name.ToString() Label1.Text = currentUserID Dim selectSQL As String selectSQL = "SELECT companyKey FROM Company WHERE UserID = ('" + currentUserID + "')"Dim cmd2 As New SqlCommand(selectSQL, con) Dim reader As SqlDataReaderDim CompanyKey Try con.Open() reader = cmd2.ExecuteReader()Do While reader.Read() CompanyKey = reader("CompanyKey").ToString() Loop reader.Close()Catch err As Exception ReaderError.Text = "Error selecting record." ReaderError.Text &= err.Message ReaderResults.Text = CompanyKey Finally con.Close() End Try
The ReaderResults.Text is not returning a value. I am not sure what is going on because the table and all columns are full, Label1.Text shows the current username of the user loggedon, and no error is showing up in ReaderError.Text.

Hi, We have an internal mail system, but when the user writes something into the textbox (textarea), he often uses enter to get the message over several lines, our problem is that when the message is saved to the database and retrieved, all the breaks are gone and its all on a single line. In the database its stored inside a field called "message nvarchar(MAX)". How can i preserve the linebreaks? example, user writes: Hello,Nice day,to go fishing. output, after it has been saved and retrieved: Hello, Nice day, to go fishing.
Any idea why I cannot see (in Enterprise Manager) all the coulmns of a selected table? All I get is * all columns - not each one, meaning I cannot select individual columns in my new view. Could it be the version? I am running SQL 7.0 SP1
I used Query Analyser to De-tach a SQL 7 database and that worked fine. The database became 'invisible' in Enterprise Manager and the entry was removed from the sysdatabases in Master. The mdf and ldf file remain in the file system. However, when I ran the sp to Attach the database QA said successful but it does not show in Enterprise Manager or in sysdatabases in Master. I'm going to run through the procedure again and if problems I'll check the logs but has anyone else had difficulty with this. Also with attaching the db to a SQL2000 install I believe the logins on the SQL7 install are not brought over. In my case, the client is using trusted logins with their database application so their is probably not a lot to manually recreate on the SQL 2000 install but doees anyone have nay sample code/script that can give me an idea of what is required in the area of getting logins out of the Master of SQL7 and into SQL2000.
I've added a new drive to a clustered instance of sql 2000. Go to the node the instance is active on, the drive shows up. But...try to add a backup device that lives on the new drive (which was, after all, the whole point of the exercise) and SQL Server is blind to that drive. I have vague recollections of it recognizing the clustered drives when i set up all this a couple years ago. Could it be that it recognizes all the drives it'll ever recognize at the moment of installation? Anybody know?
I want to have all the ethnicities from the Ethnicgroup table to be displayed in a particular area which is in where clause as aggcourseid
The problem is that even when I have a left join on the EthnicGroup table it will not return all the ethnicities but will only return those who were existing in that particular aggcourseid.
i.e. If there is no African student in E2, it will not show up in the result whereas I want to display all the ethnicities and if there is no record for aggcourseid, it should show up as 0/NULL for that ethnicity.
I have tried all sorts of joins but the problem is whenever I put in the aggcourseid in where clause, it wont bring all the records

I've been unable to determine why several published instances of my SQL Servers are not showing in AD. I searched under the Computer container in the domain in which the SQL Server was installed and did not see any SQL Server folder. I have used both the GUI and T-SQL to publish various instances, and it appeared to have worked since from the GUI the "Publish" option no longer worked and I recieved no error from Query Analyzer after issuing the command. The version is SQL Server 2000 8.0 running SP3a.
I also ran a VBScript to query the directory for published instances of SQL server, but did not get any results returned in the recordset. Any ideas?
Hi @all, I just installed SQLServer 2005 Developer edition on a WinXPPro Virtual PC. Installation went fine, however i see no items in my Start menu. There's only SQL Server 2005 Configuration tool. Where's all other stuff gone?
Everything should be on my computer, but I can't get to it. I.e. if i go check the installation (Add&remove progs/Server 2005 and click Change) there's everything there, Analysis server, Business intelligence, etc. But no items in my Start menu.
Also, if i re-enter either of the 2 installtion CDs, there's only two things in the INSTALL part: Server components and Run SQL Native Client Install... Where's "install server" link?
Please bear with me. Newbies are hard Thank you very much for any advice. Jan

I am new to SQL server and I am looking for the best practiceregarding the following:The GUI for the database I am creating has a number of questions like:A. Where are you currently living?1) In my own home2) In the home of a family member3) In a shelter4) On the streetHowever, for speed of data entry, the GUI (it's a web front-end,ASP/VBScript) accepts the number only. Futhermore the database onlystores the number entered.So for example for the above question, when the user is doing the dataentry, they would just enter a 1, 2, 3, or 4.However, when viewing the data, the end user wants to see the textthat corresponds to the number. So for example, if the user entered"3" for the above question, when they are viewing the data in the GUI(not to make edits, just viewing), they want to see "(3) In ashelter".My question is how best to display these friendly values?Should I do all the conversions in a stored procedure? If so, whatwould be the best way to do that? I tried something like this:SELECT Current_living =CASE Current_livingWHEN 1 THEN '(1) In my own home with my partner'WHEN 2 THEN '(2) In the home of a family member'ELSE NULLENDFROM tbl_DemographicInfo WHERE ClientID = @ClientIDbut I can't figure out how to do this for multiple fields.ALSO, I'm not sure if burying this stuff in a stored proc is the wayto go, because if the client wants a slight change to the friendlyname I have to get into the SP and change it. Seems like there mustbe a better way.I can also do this in the ASP code, but that also doesn't seem likethe best practice.I can have a lookup table, but again, where do I do the conversion?In an SP? With a view?Again, I'm looking for the best practice here. I know some ways Icould do it (like in the ASP), but I want to do it efficiently andcorrectly.Any help/comments are greatly appreciated.thanks in advance,Jon LaRosajlarosa at alumni dot brown dot edu
