Returning Random Records And NOT Similar (random Questions)
Jul 20, 2005Hi,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

Anyone got an idea how to do this??? I've spent 2 days trying to get stored proc. or T-SQL to work, but nothing good came out of it. I can get 1 comp and 10 cust, but not a grouped list of 20 comp. w/ 10 cust. each.

Problems Moving Data Over 8000k In DB2 Varchar Column Into SQL Server Varchar(max) Using SSIS
Nov 20, 2007
I have looked far and wide and have not found anything that works to allow me to resolve this issue.
I am moving data from DB2 using the MS OLEDB Provider for DB2. The OLEDB source sees the column of data as DT_TEXT. I setup a destination to SQL Server 2005 and everything looks good until I try and run the package.
I get the error:
[OLE DB Source [277]] Error: An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft DB2 OLE DB Provider" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".
[OLE DB Source [277]] Error: Failed to retrieve long data for column "LIST_DATA_RCVD".
[OLE DB Source [277]] Error: There was an error with output column "LIST_DATA_RCVD" (324) on output "OLE DB Source Output" (287). The column status returned was: "DBSTATUS_UNAVAILABLE".
[OLE DB Source [277]] Error: The "output column "LIST_DATA_RCVD" (324)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "LIST_DATA_RCVD" (324)" specifies failure on error. An error occurred on the specified object of the specified component.
[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (277) returned error code 0xC0209029. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
Any suggestions on how I can get the large string data in the varchar column in DB2 into the varchar(max) column in SQL Server 2005?
The Data Types Varchar And Varchar Are Incompatible In The Modulo Operator
Jan 4, 2008I am trying to create a store procedure inside of SQL Management Studio console and I kept getting errors. Here's my store procedure.
Code Block
CREATE PROCEDURE [dbo].[sqlOutlookSearch]
-- Add the parameters for the stored procedure here
@OLIssueID int = NULL,
@searchString varchar(1000) = NULL
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
IF @OLIssueID <> 11111
SELECT * FROM [OLissue], [Outlook]
WHERE [OLissue].[issueID] = @OLIssueID AND [OLissue].[issueID] = [Outlook].[issueID] AND [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
ELSE
SELECT * FROM [Outlook]
WHERE [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
END
And the error I kept getting is:
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 18
The data types varchar and varchar are incompatible in the modulo operator.
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 21
The data types varchar and varchar are incompatible in the modulo operator.
Any help is appreciated.
SSIS - Importing Varchar From Access Into SQL2005 As Varchar
Nov 20, 2006For the life of me I cannot figure out why SSIS will not convert varchar data. instead of using the table to table method, I wrote a SQL query so that I could transform the datatype ntext to varchar 512 understanding that natively MS is going towards all Unicode applications.
The source fields from Access are int, int, int and varchar(512). The same is true of the destination within SQL Server 2005. the field 'Answer' is the varchar field in question....
I get the following error
Validating (Error)
Messages
Error 0xc02020f6: Data Flow Task: Column "Answer" cannot convert between unicode and non-unicode string data types.

DTS used to be a very strong tool but a simple import such as this is causing me extreme grief and wondering of SQL2005 is ready for primetime. FYI SP1 is installed. I am running this from a workstation and not on the server if that makes a difference...
Any help would be appreciated.
Datatype Question Varchar(max), Varchar(250), Or Char(250)
Oct 18, 2007
I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.
How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?
Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?
Should I just go with char(250) and watch my db size explode?
Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.
Any insight to this would be appreciated.
Difference VarChar(50) And VarChar(500)
Nov 26, 2007
Hey,
I was doing some research on how SQL stores data on disk.
MSDN states that when storring a varchar, only the length of the data itself is used plus two bytes.
So, if you store "car" in a VarChar(50) it will take 5 bytes.
But when you store "car" in a VarChar(500) it will also take 5 bytes.
What is the reason users should define the parameter lenght?
Can you use VarChar(8000) whole the time, without any drawback?
Thanks

DTS Bug? (or Random Feature?)
Jul 16, 1999Has anyone noticed that if you created DTS package and try to
change connection properties (i.e. change DSN or redirect
DTS to different server or Database), as soon you click OK
it does not save new password and hence does not work
anymore. In my case to move Database from Development to
Production server I would have to recreate all DTS packages.
Is there any way around it?
Any ideas greatly appreciated.
Random Numbers.
Jun 22, 2001I 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()

Dec 24, 2001Is there a way to write an SQL statement to choose random values from a particular select statement..for example:

thanks in advance

Unique Random Row Id
May 4, 2006I once came across a database in which when ever a row was inserted, a unique random code was also inserted in a column. This code generated was similar to format like {8A5FE5F1-6BDA-476C-A4DB584A7710FBF91121054625}. I was told that SQL2000 has some inbuilt functionality for this.
Any idea on how to do this using SQL2000 or coding.
I feel this is much better than Identity Column as using autonumbers in quesrystring is too much risky as they easily readable.
Please help.
Thanks

Jan 9, 2004I have a customer that wants to be able to generate a random list...
-----------------------
The list is case numbers, and I can get those easy enough by saying
SELECT
dbo.table_case.id_number
FROM
dbo.table_case
Now, what I want to do is take that list and extract 1 out of every 1000, picking out random id_numbers to display.
Is this something I can do via a SQL query?

Random Number
Apr 15, 2002Generates a true random number from xxx to zzz. Uses a table variable so it all depends on the boundaries you specify how long it will take.
create procedure random_number
@lower int = 0,
@upper int = 256,
@number int = null output
as
set nocount on
declare @numbers table (number_id int identity(1,1), value int)
if @lower > @upper
begin
set @number = @lower
set @lower = @upper
set @upper = @number
end
set @number = rand((datepart(mm, getdate()) * 100000) + (datepart(ss, getdate()) * 1000) + datepart(ms, getdate()))
while (select count(*)
from @numbers) < (@upper - @lower + 1)

insert into @numbers (value)
select (@upper - @lower + 1) * rand() + @lower
end
select @number = value
from @numbers

Random String
Apr 15, 2002I used this to generate a random password. You can change what it returns to up to an 8000 character password if you feel brave. You will need this function (http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=14924) to generate the random numbers. For some reason, occassionaly a NULL (CHAR(0)) character would get in there and mess things up so I had to remove those. You could change this to even include the non alpha numeric characters.
create procedure random_password
@length smallint,
@password nvarchar(256) = null output
as
set nocount on
declare @number int
declare @lower int
declare @upper int
declare @part tinyint
if @length > 256 set @length = 256
set @password = ''
while len(@password) < @length
begin
exec random_number 0, 3, @part output
if @part = 0
select @lower = ascii('a'),
@upper = ascii('z')
else if @part = 1
select @lower = ascii('A'),
@upper = ascii('Z')
else if @part = 2
select @lower = ascii('0'),
@upper = ascii('9')
set @part = null
set @number = null
exec random_number @lower, @upper, @number output
set @password = @password + ltrim(char(@number))
if substring(@password, len(@password), 1) = char(0) set @password = left(@password, len(@password) - 1)
end

More Complex Random Example
Dec 17, 2007Hi all!
I have a table with three columns: Identity, DateTime (current_timestamp) and one which I want to fill with random values always depending on the value in the same column one row above.
Since I want it to be a stored procedure I have to pass three parameters - an initial value, the range within the random number is higher or lower than the number in the preceding row and the number of rows which should be inserted. This means that as soon as a new row is inserted there is also a new seed for the random value for the next line.
My problem now is that I would always get out the same number. Maybe you know a solution for my problem.
Many thanks and greetings from Austria
