Hi all,
I AM USING ROW_NUMBER() FUNCTION IN MY QUREY IN SQL 2005 BUT IT IS GIVING ME PROBLEM IN SQL 2000.
SO CAN U TELL ME WHAT IS THE ALTERNATE WAY TO ACHIVE SAME RESULT.
MY QUREY IS:
select row_number() over (order by SalesYTD asc) as rownum, CountryRegionName, FirstName, LastName, SalesYTD, SalesLastYear from Sales.SalesPerson
CAN U TELL ME HOW CAN I REPLACE ROW_NUMBER() FUNCTION.
THANKS IN ADVANCE

A simple Query to select alternate rows from a table ?
View 9 Replies View RelatedI have 2 Tables as below,
1) Purchase_Invoice
a. PurchaseInvoiceID
b. SupplierName
c. BillNo
d. BillDate
2) Purchase_Invoice_Items
a. PurchaseInvoiceItemID
b. PurhcaseInvoiceID (FK to Purchase_Invoice Table)
c. ItemName
d. Quantity
e. Rate
Now I want to select all the records of Purhcase_Invoice table exactly once with one column at last containing comma separated Item name of particular PurhcaseInvoiceID as below
PurchaseInvoiceID | SupplierName | BillNo | BillDate | Items (Comma Separated Items)
Currently I am using Scalar Function which takes PurchaseInvoiceID as Argument and Returns Comma Separated Itemnames€¦
It works well but when number of records are large than performance is very poor.
Is there another way of doing same thing? By Join or By some System Function?

This script is for an in-line table function, F_TABLE_NUMBER_RANGE, that generates a number table. The input parameters are the @START_NUMBER and @END_NUMBER. It returns a sorted result set containing all intergers from @START_NUMBER to @END_NUMBER inclusive.
This is an improved version of a script that I posted on a topic a few weeks ago. I modified it to cross join fewer tables based on powers of 16, instead of powers of 2, because I found that this compiled and ran much faster for small result sets (less than 10,000 rows).

I wrote a Scalar UDF in SQL2005 that returns an integer. I want to be able to display this integer in a ASP.Net 2.0 web page. I typically use a DAL for all data so I added an ObjectDataSource as a Qeury that contains only the UDF. How do I easily display the value in a Label Control or?
I have tried to use a Repeater with a label, a Formview with a Label, all to no avail. Any suggestions?

From what I've seen, the CheckSum_Agg function appears to returns 0 for even number of repeated values. If so, then what is the practical use of this function for implementing an aggregate checksum across a set of values?
For example, the following work as expected; it returns a non-zero checksum across (1) value or across (2) unequal values.
declare @t table ( ID int );
insert into @t ( ID ) values (-7077);
select checksum_agg( ID ) from @t;
-----------
-7077
declare @t table ( ID int );
insert into @t ( ID ) values (-7077), (-8112);
select checksum_agg( ID ) from @t;
-----------
1035
However, the function appears to returns 0 for an even number of repeated values.
declare @t table ( ID int );
insert into @t ( ID ) values (-7077), (-7077);
select checksum_agg( ID ) from @t;
-----------
0
It's not specific to -7077, for example:
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
0
What's curious is that (3) repeated equal values will return a checksum > 0.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
-997777
But a set of (4) repeated equal values will return 0 again.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777), (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
0
Finally, a set of (2) uneuqal values repeated twice will return 0 again.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (8112), (-997777), (8112);
select checksum_agg( ID ) from @t;
-----------
0
I have sql code that returns the correct number of record when run without an aggregate function like count(myfield) and group by myfield. It always returns 86 row which is correct when Select DISTINCT is used. As, expected when DISTINCT is not used I get double the number if rows or 172. But when I count(myfield) and group by myfield the count is 172 and not 86. The strangest thing about this is that when I am grouping a set of items
Group 1
Group 2
Group 3
The other group sum up correctly while others don't. What can explain this? Here is the code.
Select DISTINCT ws.p4Districtnumber, ws.cycle, ws.worksetid, count(msi.MeterSessionInputKey) as ASND
from fcs.dbo.WorkSet as ws
left outer join fcs.dbo.WorkAssignment as wa
on ws.WorkSetID = wa.WorkSetID
left outer join fcs.dbo.MeterSessionInput as msi
on wa.worksetkey = msi.worksetkey

How is the best way to make a function for summing an arbitrary number of times values (table parm?)- I 've read it's necessary to convert to seconds, sum then convert back, but Im' wondering if there's an alternative.
Here's the example I want to sum:
00:02:01:30
00:01:28:10
00:01:01:50
00:06:50:30
00:00:01:50
is it possible to use the window functions to count the number of rows in the previous 24hours from the current row.
I have a table of events like:
User, TimeStamp, etc...
I want to identify the row which is the event number 50 in the past 24 hours.
does the window functions can do this? and how?
the ROW PRECEDING etc... appear to not have enough feature to support time related function.
Stream-insight is able to create this type of query, but I have to do it directly in SQL.

I've a question regarding SSRS 2005.

Dear All
i want to know some alternate for the below query
"Update STR_RGSTR_DFLT " & _
" Set GST_SVY_FREQ_P = " & iNewSurveyPct & _
" Where dhc_co_c = " & iCo & " and store_i = " & iStore & _
" And RGSTR_PROTO_C not in (0,3,4,8,10,11,12,13)"
in this the values in the where clause 'not in' i.e (0,3,4,8,10,11,12,13) are directly given
but we want some alternate solution.
the entire script is writen in VBScript. these values are already populated in an array like proto_code_ary = {0,3,4,8,10,11,12,13}
shall we use that array directly without hard coding the values in the query?
If any one find a solution please let me know.

In times past I connected my web app to SQL Server by embedding the following in the web.config file: <connectionStrings> <add name="XyzApp_DB" connectionString="Data Source=MyServerSQLExpress;Database=XyzApp;User ID=sa;Password=secret_password"/> </connectionStrings> And it worked fine. But it was pointed out to me that this wasn't a very proper way to do things. So I was advised to set things up with a different connection string: <connectionStrings>
<add name="XyzApp_DB" connectionString="Data
Source=MyServerSQLExpress;Database=XyzApp;User
ID=Xyz_Admin;Password=different_password"/>
</connectionStrings>
To get this to work, I've followed these instructions: A
more secure login than “sa� is required to access your application. In the “connectionStrings� section of
“Web.config� you’ll find a User ID called “Xyz_Admin�. Here are the steps to ensure that your
DB has this login id:
a. Using
the Microsoft SQL Server Management tool, look in the root for the “Security�
folder and open it. Inside that, open
the “Logins� folder.
b. If
“Xyz_Admin� doesn’t exist then right-click on “Logins� and choose “New Login�:
i.
Enter “Xyz_Admin� in the “Login name� textbox.
ii.
Click on “User Mapping� on the left side and in the
‘Map’ column check the box beside “XyzApp�.
iii.
Go back to the “General� page and choose SQL Server
Authentication.
iv.
Specify any secret password you wish.
v.
You can uncheck “Enforce password expiration� if you
wish.
vi.
Specify “XyzApp� as the default database and press
OK.
c.
Open “Databases�, right-click on “XyzApp� and
select “New Query�. Run this query: sp_change_users_login 'update_one',
'xyz_admin', 'xyz_admin'
Now, I was pretty sure that this procedure was working fine but it doesn't seem to work for me today. I know that the client computer I'm using can connect to the DB on the server because I temporarily changed the User Id to "sa" and it connected fine. But when I change it back to "Xyz_Admin" it does not. So I'm thinking that there's something incorrect with the procedure above but I don't know what.Any ideas?Robert W.

Yes, I know synchronisation to alternate partners is deprecated in SQL2005 but....
In SQL2000 there is a Sync Partners tab in the publication properties dialog that allows you tick a checkbox for each co-publisher to be enabled as an alternate synchronisation partner. What is the equivalent in SQL2005?
I've set up replication in SQL2000 following these instructions http://support.microsoft.com/?kbid=321176 and it works. Now I'm trying to do the same thing in SQL2005 but I can't find a substitute for steps 10 & 11 in the section "Set Up the Alternate Synchronisation Partner". What's the answer?
Thanks in advance.
