I get this error when i used into storeprocedure :
ROW_NUMBER() function is not recognized in store procedure.
i used MS SQL SERVER 2005 , so i think "ROW_FUNCTION()" is not in MS SQL SERVER 2005 database library.

Calling A Stored Procedure Inside Another Stored Procedure (or Nested Stored Procedures)
Nov 1, 2007Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

SQL Server 2014 :: Embed Parameter In Name Of Stored Procedure Called From Within Another Stored Procedure?

Ad Hoc Query Vs Stored Procedure Performance Vs DTS Execution Of Stored Procedure
Jan 23, 2008
Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes

Row_Number Filtering
Jun 20, 2008I'm not sure if this is possible and have been having trouble figuring out the code to do this. I am assigning row_number to a gridview. I then want to filter the results with a dropdown. I am able to get the filter to filter the status but it either renumbers the gridview or it leaves the row numbers blank. Is there a way to have the row_numbers stick to the gridview when I filter? Example below. Thanks
Normal:IssueNumber(row_number), Status1, Open2, Open3, Closed4, Open5, Closed
"Open" Filter:IssueNumber(row_number), Status1, Open2, Open4, Open
"Closed" Filter:IssueNumber(row_number), Status3, Closed5, Closed
Help Using Row_Number For Paging

My application runs this query using a stored proc

Now I want to implement paging for the same using Row_Number so that I can display the results in pages.

Is The Transaction Context Available Within A 'called' Stored Procedure For A Transaction That Was Started In Parent Stored Procedure?
Mar 31, 2008I have a stored procedure 'ChangeUser' in which there is a call to another stored procedure 'LogChange'. The transaction is started in 'ChangeUser'. and the last statement in the transaction is 'EXEC LogChange @p1, @p2'.

Unnecessary DISTINCT With ROW_NUMBER
May 16, 2008This is gonna be a quite long explanation of an understanding problem and I seriously hope that anyone can help me out here.
Please look at the following example:
use tempdb;
create table T1
(
C1 varchar(80) not null default 'Empty'
,C2 uniqueidentifier not null default newid()
)
go
-- Add some rows
set nocount on
insert T1(C1) values('A')
go 5
insert T1(C1) values('X')
go 7
insert T1(C1) values('Y')
go 9
insert T1(C1) values('Y')
go 6
Now run the following two queries and include the actual execution plan:
select distinct
top 10
row_number() over(order by C1), C1
from T1
select top 10
row_number() over(order by C1), C1
from T1
You��ll get two different plans with the first one slightly more expansive than the second.
What I do not understand is, why the optimizer does not ignore the DISTINCT in the first case. When I include a ROW_NUMBER() without partitioning (or, to e exact: with only one partition) as in the above query, every row will get a unique number, so all returned rows are already distinct, aren��t they? But as this optimization possibility is so obvious and simple, I don��t believe that the optimizer is wrong �� rather I suppose that I��m the on, who does not understand what��s going on here.
If you play around with some SELECTs, the difference between DISTINCT included and excluded can be very noticable. Take the following example:
select distinct
top 10
row_number() over(order by a.C1), a.C1, b.C1
from T1 as a
inner join T1 as b on b.C2 = a.C2
select top 10
row_number() over(order by a.C1), a.C1, b.C1
from T1 as a
inner join T1 as b on b.C2 = a.C2
where the (unnecessary?) DISTINCT in the first query holds responsible for 34% oft he total query costs, making the cost for the first query over twice as much as for the second.
I��ve tried to find at least one example where DISTINCT makes sense �� but without success. In all my experiments (included the above, of course), always the same resultset is returned, regardless of DISTINCT or not.
The problem has been detected using an OR-mapper (nHibernate), where the SQL code is automatically generated. Inside the code generation process, a ROW_NUMBER() columnn without partitioning is always added, as well as in many cases also DISTINCT.
I��d simply like to remove the DISTINCT keyword from the code generation, because it increases the performance dramatically in many cases. But fort he reasons mentioned above, I��m not sure whether I can do this without risk.
Any ideas are greatly appreciated.

UPDATE TABLE Using ROW_NUMBER() OVER...
Jul 5, 2006Hi Champs,
I am trying to either UPDATE or add a new column with ROWNUMBER() OVER an column on a table
table:
ID------Col2----Col3---
1-------12---------1
1-------34---------2
2-------44---------1
2-------75---------2
2-------77---------3
3-------23---------1
3-------33---------2
4-------44---------1
4-------22---------2
I know I can get Col3 right with an SELECT and ROWNUMBER() OVER, but how can I UPDATE the table with the result?
/Many thanks

Nov 15, 2006I have a store procedure (e.g. sp_FetchOpenItems) in which I would like to call an existing stored procedure (e.g. sp_FetchAnalysts). The stored proc, sp_FetchAnalysts returns a resultset of all analysts in the system.
I would like to call sp_FetchAnalysts from within sp_FetchOpenItems and insert the resultset from sp_FetchAnalysts into a local temporary table. Is this possible?
Thanks,
Kevin

The above stored procedure is related to a search screen where in User is able to search from a variety of fields that include userID (corresponding column Batch.Created_By) and batchID (corresponding column Batch.BatchID). The column UserID is a varchar whereas batchID is a numeric.
REQUIREMENT:
The stored procedure should cater to a typical search where any of the fields can be entered. meanwhile it also should be able to do a partial search on BatchID and UserID.
Please help me regarding the same.
Thanks in advance.
