Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?
SET NOCOUNT ON
Declare @RandomRecordCount as int, @Counter as int
Select @RandomRecordCount = 1000
Declare @Type table (Name nvarchar(200) NOT NULL)
Declare @Source table (Name nvarchar(200) NOT NULL)
Declare @Users table (Name nvarchar(200) NOT NULL)
Declare @NumericBase table (Number int not null)
Set @Counter = 0
while @Counter < @RandomRecordCount
begin
Insert into @NumericBase(Number)Values(@Counter)
set @Counter = @Counter + 1
end
Insert into @Type(Name)
Select 'Type: Buick' UNION ALL
Select 'Type: Cadillac' UNION ALL
Select 'Type: Chevrolet' UNION ALL
Select 'Type: GMC'
Insert into @Source(Name)
Select 'Source: Japan' UNION ALL
Select 'Source: China' UNION ALL
Select 'Source: Spain' UNION ALL
Select 'Source: India' UNION ALL
Select 'Source: USA'
Insert into @Users(Name)
Select 'keith' UNION ALL
Select 'kevin' UNION ALL
Select 'chris' UNION ALL
Select 'chad' UNION ALL
Select 'brian'
select
1 ProviderId, -- static value
'' Identifier,
'' ClassificationCode,
(select TOP 1 Name from @Source order by newid()) Source,
(select TOP 1 Name from @Type order by newid()) Type
from @NumericBase

I need to pull a report that gives me the desired results as show below. I first show the data that is in the table, then below that is the desired result.
What I am trying to do is pull every employee's most recent 3 appraisal Effective Dates within the last 4 years where Rating is different than X.
Sorry I don't reall know how to explain this using code because I seem to be having a block right now. Not sure where to start really.
Any help would be greatly appreciated!! Thanks again!
Records in tblAPPRAISALS Table:

My current SQL:
SELECT DISTINCT TOP 3 Employee, Appr_Eff as [Appr Effective], Rating_Of_Rcd as [Rating]
FROM tblAPPRAISALS
WHERE Appr_Eff >= DateAdd("YYYY", -4, Date()) AND Rating_Of_Rcd <> "X"
Order by 1, 2 DESC

The select statement works correctly, I'm just not sure about how to
apply the syntax to correctly select the records in the delete

Any help from the experts here would be helpful.
Thanks

I am using this select statement to radomly display a recordSelectCommand="SELECT TOP 1 * FROM [TBL_Example] ORDER BY NEWID()I need to, however, flag this record, to determine if it has already been previously randomly selected, and won't take part in future random selections.I will need to add a where clause to the above, but what I am unsure of is what I should do for the insert statement. I guess I could figure this out on my own as well if I could determine a means to prgramatically store my PK from the above record in session.Any ideas?

I'm familiar with querying for a random record, however I can't seem to do it using a parameter driven TOP value.
Here's what I've tried in a stored procedure:
(
@Count int = 1
)
declare @sql varchar(1000)
set @sql = 'SELECT DISTINCT TOP ' + convert(varchar, @Count) + ' * FROM RandomisedView'
The view I am using looks like:
SELECT TOP 100 PERCENT dbo.TableName.* ORDER BY NEWID()
The stored procedure does not seem to cause the View to reorder the records.
I need to be able to select X random records. Any help would be appriciated.

Hello.
I need to select a random record from TABLE. It might look easy with using RAND() function, but the tricky part is that ID's which are the PRIMARY KEY, were assigned as a random number.
So right now ID's in that TABLE look some thing like that: -18745, 45809, 129, -5890023, 487910943, -209, etc...
If any one have any ideas please respond.
Thanks in advance.

Hi,I need to extract randomly 5 records from the table "Questions". Now I useSELECT TOP 5 FROM Questions ORDERBY NEWID()And it works. The problem is that I need an additional thing: if SQLextracts record with ID=4, then it should not extract record with ID=9,because they are similar. I mean, I'd like something to tell SQL that if itextracts some questions, then it SHOULD NOT extract other ones.How can I do it?Thanks!Luke

Hi
I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key

Hey all!
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
Thanks in advance,
Johan

Hi,
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks,
Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
Code snippet - getting the record thru JDBC:
DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();
// wsCon.setAutoCommit(false); //have tried with and without this flag - same results
Statements stmt = wsCon.createStatement();
String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);
if(rs.next()){
System.out.println(rs.getString("lastName"));
}
if (rs != null){
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (wsCon != null) {
wsCon.close();
}

I am attempting to create a multi-record file (as described in my last thread) and have found the following set of instructions very helpful:
http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx
I have been able to create a sample file with two of my record types.
I now need to build on this further, because I have 9 record types in total that need to be extracted to a single flat file.
does anyone have any ideas how I might extend the example above to include more record types or know of another means of achieving this?
Thanks in advance for any help you might be able to provide.

Hi,
First off, let me state that i am new to ASP.net... and have had to hit the ground running... I have looked on the net but have not found a suitable explanation on how to do this.
Let me explain what i am trying to do: In my aspx page, i have 2 dropdown boxes where the user will select a skill catagory, and then a skill. Based on that selection, i would like to compute what the Service line will be. There is a primary and foreign key on CatID on the skills and SkillCat tables. This data would need to be inserted into the another table aswell, and this would need to go into a report later.
How do i go about doing this? Some examples would be greatly appreciated. And if you know of a good link, please post it for me.

Hello Experts,
I would like to have a SQL Statement that to display all records in the same year, e.g., 2001. The date field is a mm/dd/yyyy, smalldatefield.
Could anyone advise the syntax ?
Thank you very much.

We are looking to purchase a new SQL2000 server.... Tada.... Right then, for around about the same money, we could have either 2 x PIII 1Ghz Xeon with 256Kb cache, or 2 x PIII 700Mhz Xeon with 1Mb cache.... Which choice is best for SQL Server 2000???
