I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.
Thanks for any help
Here is my problem. I have a table with 4 columns id1,id2,id3,boxnum. Here is some sample data.
id1 id2 id3 boxnum
1 1 1
1 1 1
1 2 1
1 2 1
1 2 1
2 2 2
2 3 4
What I need is to be able to update boxnum with sequential numbers based on the unique set of values from the id columns. So my output would be this.
id1 id2 id3 boxnum
1 1 1 1
1 1 1 2
1 2 1 1
1 2 1 2
1 2 1 3
2 2 2 1
2 3 4 1
I have a table with a field called "host" and I want to replace the value of this column in each row with 'Host' followed by a random number. I have created the below function to do this:
DECLARE @Random varchar;
SELECT @Random = CONVERT(int, (20+1)*RAND())+ 1;
UPDATE AnalogLines Set [Host Name] = 'Host' + @Random
This sorta works... the problem is, the random number is determine and then the SAME random number is applied to each row. I need a different random number for every row. Any ideas?
I have a column within a table which is already truncated/deleted all records within (Microsoft SQL 2008). I have to now populate the column with sequential numbers up to 50,000 records arbitrary numbers (doesn't mater) up to 7 characters.
what SQL statement I need to write that will automatically polulate the newly empty table with A000001,A0000002,A0000003, or any form for that matter etc so that I can sort number the records within the table.
I have approximately 50000 records which I need to sequentially entered and I really dont want to number the column manually via hand editing.
I'm grappling with this issue which I thought was basic VB programming; I'm trying to insert a random number (between 100 and 999) into a SQL table column (=Status_ID). This is input as part of a user submitting helpdesk requests via a APS.Net Web Form. The 'Status_ID' field is obviously not visible to the user but will help reference this Helpdesk request on the database.Here is the code:Protected Sub submitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitButton.Click If Page.IsValid Then ' Define data objects Dim conn As SqlConnection Dim comm As SqlCommand ' Read the connection string from web.config Dim connectionString As String = _ ConfigurationManager.ConnectionStrings("ITNet_Students").ConnectionString ' Initialize connection conn = New SqlConnection(connectionString) ' Create command comm = New SqlCommand( _ "INSERT INTO HelpDesk (First_Name, Last_Name, StudentID, PersonalEmail," & _ "CategoryID, SubjectID, Description, StatusID) " & _ "VALUES (@First_Name, @Last_Name, @StudentID, @PersonalEmail, " & _ "@CategoryID, @SubjectID, @Description, @StatusID)", conn) ' Use randomize Randomize() Dim randomvalue As Integer ' Generate random value between 999 and 100. randomvalue = Int((900 * Rnd()) + 100) ' Add command parameters comm.Parameters.Add("@First_Name", System.Data.SqlDbType.NVarChar, 50) comm.Parameters("@First_Name").Value = fnameTextBox.Text . . . comm.Parameters.Add("@StatusID", System.Data.SqlDbType.Int) comm.Parameters("@StatusID").Value = randomvalue 'Enclose database code in Try-Catch-Finally Try ' Open connection conn.Open() ' Execute the command comm.ExecuteNonQuery() ' Reload page if the query executed successfully Response.Redirect("HelpDesk.aspx") Catch ' Display error message dbErrorMessage.Text = _ "Error submitting the help desk request! Please try again later, and/or change the entered data!" Finally 'close connection conn.Close() End Try End If End Sub----------------------------------------------------------------------------------------------------------------------I keep getting the error message under 'Catch' and the page 'HelpDesk.aspx' is not reloading; the 'comm.ExecuteNonQuery()' is not executing.Can anyone spot any inconsistencies in the declaration of the 'randomvalue' variable?P.S: this code works fine if you replace 'randomvalue' with any integer in 'comm.Parameters("@StatusID").Value = randomvalue'
View 2 Replies View RelatedHello,
I need to sample data in a very large table in SQL Server 2000 (a gazillion rows of Performance Monitor statitics).
I'd like to take the top 5%, for instance, based upon a column containing random numbers.
Can anyone suggest a highly efficient method of populating a column with random numbers.
Thanks in advance.

I have a query which returns information about transactions similar to this:
Select account, trans_code, quantity
from ledger_table
This returns something like:
acct trans_code quantity
----- ---------- ------------
2 2 1000
2 3 500
2 3 300
3 2 100
3 2 500
etc.
What I need to do is add a lot number for each acct/trans code type. This is merely a sequential number for the transaction. This changes the output as follows:
acct trans_code quantity lot
----- ---------- ------------ ---
2 2 1000 1
2 3 500 1
2 3 300 2
3 2 100 1
3 2 500 2
3 3 1000 3
3 5 200 1
etc.
The lot number is reset for each grouping.
Does anyone have a way to do this outside of a cursor or temp table?
TIA, any help greatly appreciated.
I am trying to automatically insert records into my existing customer table. Is there a way when I insert these new records and assign the customer number that it can sequentially pick the next available unique customer number for each record that is inserted? for example the first record would be customer number 100, the next 101, and so on? Please advise.

View 1 Replies View RelatedI have a database that is pre-populated with sequential part numbers.As people reserve the parts I update a flag to show the # is no longeravailable.

Hi,
Can anyone tell me offhand the simplest/most elegant way of updating an integer column to a sequential column of numbers with a query?
e.g given
intval | Description| Cost
0 | Descvalue0| 4.32
2 | Descvalue2| 4.33
3 | Descvalue3| 4.34
8 | Descvalue8| 4.35
change it to:
intval | Description| Cost
0 | Descvalue0| 4.32
1 | Descvalue2| 4.33
2 | Descvalue3| 4.34
3 | Descvalue8| 4.35
I think it might need a stored proc..
Many Thanks

112 2 (the numbers 113,114)
113 1 (the numbers 114)
114 0
How can I do It?
I am trying to get random numbers to have a unique value for different processes, then I can identify each process. What happens is that I use rand() function without seed, so I got my random numbers, but after shutting down SQLServer and try to get again another random number after booting up, the same series of random numbers is given again and again. So if anyone knows how I can get unique values,even though reseting the server, and using random function or any other method which automatically provides unique values,I'll really appreciate it if you let me know it.
This is the function: select rand()

Hi there... I've got an interesting one, that I can't seem to get my head around. Maybe some legend out there might be able to give me a hand...
I'm looking for a way to produce a weighted set of random numbers. I'm doing some work for a client at the moment, and they want to issue 3 random "reward cards" to their members at certain times. These are a bit like discount vouchers etc. The problem is some cards have need to have a higher frequency than the others. I guess a similar problem to baseball cards, you buy a pack of cards, you get mostly common cards, but every now and then, you get a rare card.
Here is the table setup:
CREATE TABLE [dbo].[Cards](
[CardID] [uniqueidentifier] NOT NULL CONSTRAINT [DF_Cards_CardID] DEFAULT (newid()),
[CardName] [nvarchar](50) NOT NULL,
[InsertRatio] [float] NULL,
CONSTRAINT [PK_Cards] PRIMARY KEY CLUSTERED
(
[CardID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 1', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 2', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 3', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 4', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 5', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 6', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 7', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 8', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 9', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Rare 1', 0.02) /* 1:50 ratio */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Rare 2', 0.02) /* 1:50 ratio */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Rare 3', 0.02) /* 1:50 ratio */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Very Rare 1', 0.005) /* 1:200 ratio */
So what I need to do, is have a Stored Proc that I can execute and it returns back 3 random rows. Now in that single run, a card can't be duplicated.
Notice the Insert Ratio column? This has the ratio of the probability, eg a 1:50 insert ratio is equal to 0.02. For the common cards, a NULL value indicates it is a common.
Eventually, this table would have about 1000 rows in it, and about 200 of those would have various ratios (eg 1:50, 1:200, 1:1000, 1:8000 etc)
Any ideas or comments?
Thanks in advance.

s it possible to create random numbers within a range like : .28 to .57 ?
UPDATE Nop_ProductVariant
SET percent = RAND() .28 to .57
So the percent field would look like :
ProdID percent
1001 .38
1002 .29
1003 .40
etc . .
all rows having a different value
While trying to solve a SQL challenge I found myself trying to understand what is happening when you CAST a INT to date time.
Trying to understand the results. Here are some random numbers and Castings. My question is why do they produce the datetimes they do?
SELECT CAST((1.1) AS DATETIME)
SELECT CAST((200) AS DATETIME)
SELECT CAST((15) AS DATETIME)
SELECT CAST((99.99999) AS DATETIME)
Why does M$ Query Analyzer display all numbers as positive, no matterwhether they are truly positive or negative ?I am having to cast each column to varchar to find out if there areany negative numbers being hidden from me :(I tried checking Tools/Options/Connections/Use Regional Settings bothon and off, stopping and restarting M$ Query Analyer in betwixt, butno improvement.Am I missing some other option somewhere ?

I'm trying to write data to excel from an ssis component to a excel destination.
Even thought I'm writing numerics, every cell gets this error with a green tag:
Convert numbers stored as text to numbers
Excel Cells were all pre-formated to accounting 2 decimal, and if i manually type the exact data Im sending it formats just fine.
I'm hearing this a common problem -
On another project I was able to find a workaround for the web based version of excel, by writing this to the top of the file:
<style>.text { mso-number-format:@; } </style>
is there anything I can pre-set in excel (cells are already formated) or write to my file so that numerics are seen as numerics and not text.
Maybe some setting in my write drivers - using sql servers excel destination.
So close.. Thanks for any help or information.

Large design flaw, I know, but we have a table with a varchar field which contains alpha - numeric values. I need to change just the numerics, which can be in an position on the field:
Sample data of the field:
Rec1: Sally Morgan 201-555-1212
Rec2: 555-4040 John Smith
Rec3: Jane Houstin 201-555-6452 ext1223
Desired result:
Rec1: Sally Morgan 999-999-9999
Rec2: 999-9999 John Smith
Rec3: Jane Houstin 999-999-9999 ext9999
There's a bunch of UDFs out there for selecting just the numerics, but I'm having trouble throwing it into a viable script for repeatable execution.

Id is not primary key, but should not duplicates keys, it is just a column want to generate serial number (1,2,3,4...etc) How to generate?
If Exists ( Select c.name from sys.columns c where object_id = object_id('HH835HP') and C.name = 'ID_1' )
Begin
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
End;
Obviously... The stuff inside the IF is wrong syntax...I mean
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
I have a below table,

1. update all child items with ascending numbers starts with 1 against each parent and each report.
2. for each different parent or different report, order by should starts with 1 again.
Hello.
Whats the easiest way to add a column with a numeration to my table?
I want the users to have an easier life finding on which row they are
talking.
I preffer of course doing it in reporting service and not adding a
column in my dataset.
Thanks.
In microsoft sqlserver 7.0 i like to what is function name to generate serial numbers in a table.
For ex: in sybase we have number* which will automatically generate unique
numbers for each row.
It will be great if you could reply at the earliest
