SQL2K5 SP2 - 'ROW_NUMBER' Is Not A Recognized Function Name

Aug 15, 2007

The row_number functions doesn't seem to be operable in our version of SQL Server 2005 SP2.

We have completely tried everything, including using the sample database, and Query posted in the 2005 SQL Server 2005 Book, which is as follows:


SELECT empid, qty,

ROW_NUMBER() OVER(ORDER BY qty) AS rownum

FROM dbo.Sales

ORDER BY qty;


I get the following error:


Msg 195, Level 15, State 10, Line 2

'ROW_NUMBER' is not a recognized function name.

Below you will find the versions of SQL we are using of 2005.


Microsoft SQL Server Management Studio 9.00.3042.00
Microsoft Analysis Services Client Tools 2005.090.3042.00
Microsoft Data Access Components (MDAC) 2000.085.1117.00 (xpsp_sp2_rtm.040803-2158)

Can anybody know ,how can we add  builtin functions(ROW_NUMBER()) of Sql Server 2005  into database library.
I get this error when i used into storeprocedure :

'EncryptByPassPhrase' Is Not A Recognized Function Name.

Mar 2, 2006

I am trying to run the following code in SQL Server 2005:

DECLARE @cleartext NVARCHAR(100)

DECLARE @encryptedstuff NVARCHAR(100)

DECLARE @decryptedstuff NVARCHAR(100)

SET @cleartext = 'XYZ'

SET @encryptedstuff = EncryptByPassPhrase('12345', @cleartext)

SELECT @encryptedstuff

SET @decryptedstuff = DecryptByPassphrase('12345', @encryptedstuff)

SELECT @decryptedstuff



and am recieving an error:

Msg 195, Level 15, State 10, Line 5

'EncryptByPassPhrase' is not a recognized function name.

Msg 195, Level 15, State 10, Line 7

'DecryptByPassphrase' is not a recognized function name.



It appears as though this EncryptByPassPhrase and DecryptByPassphrase as supported in 2005 T-SQL commands but when I execute this code in SQL Server Studio it errors out.

Anyone know why?

'INITCOLVS' Is Not A Recognized Built-in Function Name.

Nov 27, 2007

I have read all of the messages related to the above problem and none have solved the issue.
We have migrated a SQL 2000 database to SQL 2005.  Detached from one and attached to the other and then based on some of the conversation I also used the SQL Server 2005's copy option and copied the database.  Detached the old one and renamed the new database which was created in the copy process to the old name.  Basically getting back to where I started.  By the way there are no triggers generated during the process (as was mentioned), nothing to delete as some of the discussion was suggesting.  
Big databse, lots of tables and stored procedures.  All screens seem to work except when we try to update some data using a stored procedure which takes the data and updates the table.  End up getting the above error during the execution.  All used to work fine with SQL Server 2000.  I have taken the SQL out of the stored procedure and executed manually and it worked but leaving the stored procedure alone and calling it with the updated data we get the INITCOLVS problem.  The database is also set to be compatible to 90 so that suggestion also has not fixed the problem.  Looking for additional suggestions and solutions.  Some one was talking about making a dummy INITCOLVS function, have not done this yet but don't particularly like this suggestion, like to know the cause and the proper solution to the problem.
Again in summary:
Migrated SQL 2000 database to 2005
Have done the copy and attach process to make sure the whole conversion to SQL Server 2005 has taken place.
Have set the compatibility of the database to 90
Updates cause the above error. 
 
 Thanks in advance.

Date Is Not A Recognized Built-in Function Name

Mar 21, 2013

how to format the last part of this query which comes from Access.:

SELECT Max(TITLOC.TitleLocID) AS MaxOfTitleLocID, TITLES.TitleID, TITLES.CustLName, TITLES.CustFName, TITLES.RecDT, TITLES.TitleID
FROM (TITLES_WARNING_SENT_qry RIGHT JOIN TITLES ON TITLES_WARNING_SENT_qry.TitleID = TITLES.TitleID) INNER JOIN TITLOC ON TITLES.TitleID = TITLOC.TitleID
WHERE TITLES_WARNING_SENT_qry.TitleID Is Null
GROUP BY TITLES.CustLName, TITLES.CustFName, TITLES.RecDT, TITLES.TitleID, TITLES.TitleID
HAVING (TITLES.RecDT<Date()-31)

I am getting:
'Date' is not a recognized built-in function name.

It is probably something simple but how would I go about converting this part "HAVING (TITLES.RecDT<Date()-31)" to something SQL Server is happy with?

FREETEXT And CONTAINS Keywords Generate `not A Recognized Function Name`

Sep 14, 1998

I installed SQL server 7.0 beta 3 and I have been experimenting with the full text search capabilities. The catalogs appear to build correctly, but when I issue a query against the full text database, isql/w always returns with `contains` is not a recognized function name. I am confident of my query syntax, since I can execute an identical query against a database without full text search enabled and I get an error stating that the target database does not have full text searching enabled. Has anybody else encountered this? I am hoping that I am missing something obvious/simple.

Sp_columns In SQL2K5 Gives No Rows For Function That Return Table

May 9, 2006

Some automated tools use sp_columns to find out the columns for a table, view or UDF that returns table.

In SQL Server 2000 it gives columns back but in SQL Server 2005 it does not, compat level set at 80 and 90.

Does anyone have an idea what id going on here?

Repro script below. I expect the script to return information about the two columns in the table defined in fnTestColumnsFromFunctions().

if exists (select 1
from sysobjects
where id = object_id('dbo.fnTestColumnsFromFunctions')
and type in ('IF', 'FN', 'TF'))
drop function dbo.fnTestColumnsFromFunctions;
go

create function dbo.fnTestColumnsFromFunctions()
returns @TestTable table
(
ttID int,
ttName varchar(50)
)
as
begin
return;
end
go

declare @dbname sysname;
declare @n int;
set @dbname = db_name();
exec @n = dbo.sp_columns
@table_name = 'fnTestColumnsFromFunctions',
@table_owner = 'dbo',
@table_qualifier = @dbname,
@column_name = null,
@ODBCVer = 2;

&"MAXRECURSION&" Keyword Not Recognized Within Function?

Mar 20, 2007

Koroner writes "Hi all. I'm very new to SQL programming so when I started coding I already expected some problem like the one I now describe to present itself soon.
I'm not an English native speaker, pardon me for making any mistake.

I'm currently programming in ASP.NET using Visual Studio.

I've defined a function which consists of one quite simple query calling itself in a recursive way. The problem occurrs when running a view to check whether the function works prorperly, since the "nesting limit exceeded" error (not exact words) pops up.
I didn't know there was such a limit.

Searching the Web I've learnt there is a way to modify this limit, that is using the OPTION clause and the MAXRECURSION hint.

But the fact is whenever I add the OPTION clause to the SELECT of my function Visual Studio tells me that there is a syntax error near "OPTION" keyword. I'm sure VS is not recognizing the "MAXRECURSION" keyword, because there are no syntax errors and the word is not colored in blue (unlike other keywords).

What puzzles me most is that I tried to define a recursive SELECT provided with OPTION clause within a view or an on-the-fly query and all works fine there.

Thanks for any reply."

Row_Number Filtering

Jun 20, 2008

I'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

Apr 25, 2008

Hi,

My application runs this query using a stored proc

SELECT empid1,name1,joindate from emp where empid2=3
union
select empid2,name2,joindate from emp where id1=3

Now I want to implement paging for the same using Row_Number so that I can display the results in pages.
Can someone please help me write a query for the same. I tried playing with Row_Number but no luck with it.Basically I am not good with SQL and I had programatically implemented paging in asp.net by looping through all records returned by the query.



Thanks,

Unnecessary DISTINCT With ROW_NUMBER

May 16, 2008

This 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.

Row_number And Isnull Commands

Oct 24, 2007

I am running a row_number fucntion but i do not have the correct sequence when i am including isnull expression, but maybe the problem is when i am trying to join the tables
my script is something like this:


SELECT TOP (100) PERCENT row_number() over( partition by a.Blasthole_Name order by a.DEPTH) as seq,

a.Blasthole_Name, a.ACTUAL_NAME, b.loaded_diameter, isnull(( select max(Z.DEPTH) from dbo.Drillability Z

where Z.Blasthole_Name = a.Blasthole_Name and Z.DEPTH < a.DEPTH), 0) as [from], a.DEPTH,

FROM dbo.Drillability a FULL OUTER JOIN

PD_Data.dbo.db_drill_hole_base b ON a.Blasthole_Name = b.drill_hole_id

GROUP BY a.Blasthole_Name, a.DEPTH, b.loaded_diameter

in shorts words i need something like this

seq Blasthole_name loaded_diameter from depth

ROW_NUMBER() And Projected Row Count.

May 15, 2006

Is there a way without rerunning the select query to get the "total row count" using

ROW_NUMBER and BETWEEN as such..

SELECT * FROM

(SELECT ROW_NUMBER() OVER(ORDER BY Year DESC, Month DESC, Day DESC) as RowNum,

e.id, e.Title

FROM Events e



) as DerivedTableName

WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1

typically i would build a temp table and return SELECT @@ROWCOUNT

UPDATE TABLE Using ROW_NUMBER() OVER...

Jul 5, 2006

Hi 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

Updating Values During SELECT Using CTE And Row_Number()

Sep 19, 2007

Hi,
I'm very new to stored procedures and I've been searching on google to find a way to custom page my results using SQL Server 2005. I'm trying to use Row_Number() and a CTE to keep things efficient and scaleable but I keep getting an error next to my UPDATE statement.
I get the following error: "[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near the keyword 'UPDATE'."
The sproc works without the UPDATE statement. Does anyone know where I need to put the UPDATE statement to update the "searched" field for each record selected?
 
CREATE PROCEDURE [zk_update_request_england](@property_type     tinyint,@market_status     tinyint,@price             int,@bedrooms          tinyint,@search_location   varchar(30),@search_district   varchar(30),@PageSize   int,@PageIndex  int)
AS
BEGIN
WITH SearchResults AS(
   UPDATE dbo.zk_request_england   SET    searched = searched + 1   WHERE  property_type = @property_type   AND    market_status = @market_status   AND    bedrooms = @bedrooms   AND    search_location = @search_location   AND    search_district = @search_district   AND    min_price <= @price   AND    max_price >= @price 
   SELECT user_id,          min_price,          max_price,          property_description,          searched,          ROW_NUMBER() OVER (ORDER BY max_price DESC) AS RowNumber   FROM   dbo.zk_request_england   WHERE  property_type = @property_type   AND    market_status = @market_status   AND    bedrooms = @bedrooms   AND    search_location = @search_location   AND    search_district = @search_district   AND    min_price <= @price   AND    max_price >= @price
)
   SELECT user_id,          min_price,          max_price,          property_description   FROM   SearchResults    WHERE RowNumber BETWEEN (@PageIndex - 1) * @PageSize + 1 and @PageIndex*@PageSize
END
 
Thanks in advance for any help.
