I have an application under test, where I iteratively reset an export batch and then run the export for different configurations. For major testing, I wish to test each config over the full monty, 70k documents exported, but for dev testing I like to keep the rows in each section down to 500. Last night in the interests of not breaking code, I was popping ‘TOP 500’ into each query, but I’m sure there is a better way. Any suggestions will be appreciated. I’m using a SqlDataAdapter to fill my DataTable objects.

hai,
i m using SQL server 2000.
i have 3 columns A,B,C respectively. the columns consist of the following values.
Col-A: a,b,c,d,e,f,g,h,i,i,i,i,i
Col-B: j,k,l,m,n,o,p,q,r,i,r,r,r
Col-C: s,t,u,v,w,x,y,z,a,b,c,n,s
I need the output as
Col-D: a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z
Note : Commas are not needed. just in row-wise
i.e, i want to combine 3 columns and want to remove the REPEAT values,NULL and EMPTY
how to achieve it? - KARAN

here it is my quick solution:
select distinct cola <br />
from myTable<br />
union all<br />
select distinct colb from myTable where colb <> (select top 1 cola from myTable order by cola desc)<br />
union all<br />
select distinct t3.colc from myTable as t3 where t3.colc <='z' and t3.colc >(select top 1 colb from myTable order by colb desc)

thanks blue_boy.
but all the three columns is in the same table and i dt know the last value whether the last value is "z" or anyother (since, i cant understand {t3.colc <='z'} statement)
|
|
|
|
|
Instead harcoded 'z' condition then modified query looks like this:
select distinct cola <br />
from myTable<br />
union all<br />
select distinct colb from myTable where colb <> (select top 1 cola from myTable order by cola desc)<br />
union all<br />
select distinct t3.colc from myTable as t3 <br />
where t3.colc <=(select top 1 colc from myTable order by colc desc)<br />
and t3.colc >(select top 1 colb from myTable order by colb desc)
result of this query comes from one table in my case named myTable

|
|
|
|
|
The Final result should not contain any NULL or EMPTY values..................
Now the NULL is removed. how about the EMPTY?
|
|
|
|
|
The way how you eliminate NULL values same do with empty text.
e.g
columnname <> ''

Basically you will need set up your SQL Server installation using Windows authentication so that each user logs in using their Windows credentials.
You can then apply security settings for each user depending on which tables etc you want them to have access to.
There is a lot more behind this which google will more than help with.
What I have described above should get you heading in the right direction.

I need to store my RTF files in a database. I have tried WRITETEXT function for that and also normal insert command. My problem is when I read the file back from database (using READTEXT and normal SELECT) and save it to hard disk the file gets corrupted . ( 28 characters are added at the begining of the file . When I remove those redundant characters the file can be opened by wordpad). Why is it ? Do you have any idea of storing files on database and retrieving them ? I use SQL Server 2000.

I have this table
UserAttributes
UserAttributeId int identity (1,1) not null
AttributeId int not null
UserId int not null
AttributeValue default (1) not null
Attribute Id is a FK to a table of attributes and user Id is a FK to the table of users. I am trying to create a trigger that whenever AttributeValue is changed that the sum of the two highest attributes is loaded into a field in the Users table. I would like it to be one statement (so I don't have to iterate a cursor), but I'm stuck on the syntax. Any ideas?

Hi
I am not clear with your question, do you want to get two maximum values from a column without using cursor?
Please go thro' the following SQL Script, I am not sure whether you are looking for this solution:
USE northwind<br />
<br />
DECLARE @MaxStock SMALLINT<br />
DECLARE @NextMaxStock SMALLINT<br />
<br />
SELECT <br />
@MaxStock = MAX(UnitsInStock) <br />
FROM <br />
PRODUCTS<br />
<br />
SELECT <br />
@MaxStock<br />
<br />
SELECT <br />
@NextMaxStock = MAX(UnitsInStock) <br />
FROM<br />
PRODUCTS <br />
WHERE <br />
UnitsInStock < @MaxStock<br />
<br />
SELECT <br />
@NextMaxStock<br />
<br />
SELECT <br />
@MaxStock + @NextMaxStock<br />
Hope this is clear.

You could try something like:
Select Sum(AttributeValue)<br />
From<br />
(<br />
Select top 2 AttributeValue<br />
From UserAttributes<br />
Order by AttributeValue desc<br />
)

I'm trying to retrieve an image from Sybase DB using VB.Net. The field (sImage) is of type
"image". I've tried with dataset and dataReader, but no luck so far.
Here is what I have done:
This code works fine for SQL Server database.
Example:
Dim strConn As String
Dim strQuery As String
Dim objConn As OleDbConnection
Dim objDs As New DataSet
Dim intId As Integer
Dim objDa As OleDbDataAdapter
intId = Request.QueryString("uniqueId").ToString()
strQuery = "Select SImage From IMAGE Where ImageId= " & intId
strConn = ConfigurationManager.AppSettings.Get("ConStr")
objConn = New OleDbConnection(strConn)
objDa = New OleDbDataAdapter(strQuery, objConn)
objDa.Fill(objDs)
If Not IsNothing(objDs) AndAlso objDs.Tables.Count > 0 Then
Response.BinaryWrite(objDs.Tables(0).Rows(0)("SImage"))
End If
objDa.Dispose()
The code gave me this error:
"Invalid cursor position"
I'm using The Sybase DB version 9 .0.1
I'm stuck here so please help me!
