Hi,
I have DB monitoring jobs which use Sysperfinfo to monitor some of the counters. On One SQL 2K Server since few days the select on sysperfinfo returns 0.
Do you think I need to start any service from the OS side to enable this?
Your input is highly apppreciated.
Thanks,:confused:

Good day,
I just like to ask if anybody has experienced getting empty rows from SQL data adapter? I'm using SQL Server 2005. Problem is when the sql is run on Query Analyzer it retrieves a number of rows but when used in my application it returns 0 or empty rows.
I thought the connection is not the problem since I got my columns right. Below is my code snippet.
Thanks!
const string COMMAND_TEXT = @"select distinct somefield as matchcode, count(somefield) "
+ "as recordcount from filteredaccount where StateCode = 0 group by somefield having count(somefield) > 1";
SqlDataAdapter adapter = new SqlDataAdapter(COMMAND_TEXT, connection);
DataTable dt = new DataTable(sometablename);
adapter.Fill(dt);
Hi everyone:
I guess this should be a simple question but have not been able to find the answer, does anyone know how to make a SQL Sentence to return at least one row when counting?
SELECT COUNT(Id_Field), Field2 FROM Table1 WHERE Code_Field = 1 GROUP BY Field2
This will return 0 rows when the where criteria is not matched by any record on the Table1, but I would like to have one row counting 0 rows, in stead it returns no rows at all.
Thanks for any help.
Hi all,
I am trying to build a association table (t2) to store a list of users
have viewed an item in my records table (t1). My goal is to send the
UserID parameter to the query and return to the user a read / not read
marker from the query so I can handle the read ones differently in my
.net code. The problem is that I cannot work out how to return anything
but the read data to the client. So far my stored proc looks like this
DECLARE @UserID AS Int -- FOR TESTING
SET @UserID = 219 -- FOR TESTING
SELECT t1.strTitle, t1.MemoID, Count(t2.UserID) AS ReadCount,t2.UserID
FROM t1
LEFT OUTER JOIN
t2 ON t1.MemoID = t2.MemoID
WHERE t2.UserID = @UserID
GROUP BY t1.MemoID, t1.strTitle,t2.UserID
It works fine but only returns those records from t1 that are read. I
need to return the records with null values also! I may have built the
assoc table wrong and would really appreciate some pointers on what I
am doing wrong. (assoc table has rID, MemoID and UserID columns)
Please help!
Many thanks
Hi,

I have the following query:
select sq.*, p.numero, p.nombre
from paf p right outer join dbo.GetListOfSquaresForShippingLot(@lot) sq on sq.number = p.numero and sq.version = p.numero
The @lot parameter is declared at the top ( declare @lot int; set @lot = 1; ). GetListOfSquaresForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.
If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.
I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.
What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.
PLEASE HELP!!!!
Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:
CREATE FUNCTION [dbo].[GetTabListOfSquaresForShippingLot]
(
@ShippingLot int
)
RETURNS
@result TABLE
(
Number int, Version int, Position smallint,
SubModel smallint, Quantity smallint,
SquareId nvarchar(5),
ParentSquareId nvarchar(5),
IsSash smallint,
IsGlazingBead smallint,
Width float,
Height float,
GlassNumber smallint,
GlassWidth float,
GlassHeight float
)

BEGIN
INSERT INTO @result
SELECT *
FROM dbo.GetListOfSquaresForShippingLot(@ShippingLot)
RETURN
END
I maintain a simple employment (job) tracking web application.
Jobs can be set to 5 different statuses: Open, Closed, Filled, Pending, or Cancelled.
There is a table in the database called statusLog, which records everytime a job is set to opened, or set to closed, etc. It records the job number, the date it was changed, and what the job was changed to.
Here is a short example of what a few entries might look like:
Status Date Job number
Open10/6/2002 2:34:56 PMTEST2845
Hold10/11/2002 12:19:29 PMTEST2845
Closed10/29/2002 2:00:54 PMTEST2845
Pending10/25/2002 3:37:06 PMTEST2877
What I need to do is write an SQL query that will return to me all entries in this table, between two certain dates, that ONLY have entries during those dates.
Basically I need to know how many "new" jobs were set to open during a month. I can easily just do a count of how many jobs were set to open, but this will not give a count of "new" jobs.
Example: during june a job could be set to open. Then in july it could be set to pending. Then in august, it could be re-opened, and set to open.
If I ran this query for the month of August, it would return that job as being opened in august. But it wasn't a new job, meaning it had already been in the system in previous months.
Is there some way I can select all "Open" jobs, between a certain date, that do not exist anywhere in the table previous to the date it was entered? This would give me a result set containing only new jobs.
The only way I've thought of yet is to get a result set of all jobs simply set to open during a month, then one by one for each record, go back and run another SQL query to see if it exists in the table anywhere other than in that month.
This seems horribly inefficient to me however, as I do not want to be doing 34,000 independent SQL calls for every single "open" job it finds during a certain month.
thanks
We are running the following query, which has a unique index on Table_2 (col1 and sys1), and Column col1 from Table_1 is unique.
select top 100 s.*, x.col1
from Table_1 s
left outer join Table_2 x
on x.col1 = s.col1 and x.sys1 = 'SYSTEM0'
Unfortunately this query returns duplicate rows. And every time the result is different
But once we dbcc dbreindex the unique index on Table_2, the result will not have any dups.
Any ideas?
Thanks

Here is my query which returns multiple rows
SELECT
R.name, R.age,R.DOB,
ISNULL(D.Doc1,'NA') AS doc1,
ISNULL(C.Doc2,'NA') AS doc2
FROM
REQ R
inner join RES S ON R.Request_Id=S.Request_Id
inner join RES1 D ON D.Response_Id=S.Response_Id
inner join REQ1 C ON C.Request_Id=R.Request_Id
select * from RES1 where Response_Id = 111 -- return 3
select * from REQ1 where Request_Id = 222 --- returns 2
So at last inner join retuns 3*2 = 6 records , which is wrong here and i want to show 3 records in doc1 row and 2 records in doc 2 rows ...
Without systemAdmin role, xp_AvailableMedia can still run (after granting execute permission) but just return 0 rows.
It seems we have to give the user SystemAdmin role, in order to get the list of devices in SQL 2005, while in previous versions of SQL Server, the user granted the execute permission for xp_AvailableMedia will be able to get the list of devices.
Is this be design? Is there any way the a NON-SA user can retrieve device list? If yes, what extra permissions do we have grant?
Thanks in advance for your help.

View 1 Replies View RelatedI'm pretty new to .NET and am looking for advice on how to speed up a simple stored procedure that returns 35,000 plus rows. It's a super simple query that returns a client list. It's just that there is soooooo many rows, it's super slow when the page loads.
View 4 Replies View RelatedHello All.
I am struggling with the below join block in my stored procedure.
I can't seem to get the duplicate row problem to go away. It seems that SQL is treating each new instance of an email address as reason to create a new row despite the UNIONs.
I understand that if I am using UNION, using DISTINCT is redundant and will not solve the duplicate row problem.
Primary Keys: none of the email address columns are primary keys. Each table has an incrementing ID column that serves
as the primary key.
I am guessing I am encountering this problem because of how
I have structured my Join statements? Is it possible to offer advice without a deeper understanding of my data model or
do you need more information?
Thanks for any tips.
Code:
select emailAddress from Users union
select user_name from PersonalPhotos union
select email_address from EditProfile union
select email_address from SavedSearches union
select distinct email_address from UserPrecedence union
select email_address from LastLogin) drv
Left Join Users tab1 on (drv.emailAddress = tab1.emailAddress)
Inner Join UserPrecedence tab5 on tab5.UserID=tab1.UserID
Left Join PersonalPhotos tab2 on (drv.emailAddress = tab2.user_name)
Left Join LastLogin tab4 on (drv.emailAddress = tab4.email_address)

I don't understand using a dynamic cursor.
Summary
* The fetch next statement returns multiple rows when using a dynamic cursor on the sys.dm_db_partition_stats.
* As far as I know a fetch-next-statement always returns a single row?
* Using a static cursor works as aspected.
* Works on production OLTP as well as on a local SQL server instance.
Now the Skript to reproduce the whole thing.
create database objects
-- create the partition function
create partition function fnTestPartition01( smallint )
as range right for values ( 1, 2, 3, 4, 5, 6, 7, 8 , 9, 10 ) ;
[Code]....
Why does the fetch statement return more than 1 row? It returns the whole result of the select-statement. When using a STATIC cursors instead I get the first row of the cursor as I would expect. Selecting a "normal" user table using a dynamic cursor I get the first row only, again as expected.
I have a query that based 2 tables. I wrote a query with a left join on the base table but the result set returns multiple rows for each occurrence in the second table because of the left join. I want but to return all records from on table A and only matching records from table B which id but I would wan tit to keep return them vertically as the because it make it difficult to read when put in a spreadsheet. It want it to return the values horizontally so the rows are not increasing for each occurrence on table b.

I have a simple query that joins a largeish fact table (3 million rows) to a view that returns 120 rows. The SKEY in the view is returned via a scalar function. The view returns instantly if queried on it's own however when joined to the fact table in the simple query below results in a query execution plan that runs forever. Interestingly if I change the INNER JOIN to a LEFT OUTER JOIN the query returns the matched results almost instantly.
Select
Dimension.Age_Band.[10_Year_Age_Band],
Count(*)
From
Fact.APC_Episodes
Inner Join Dimension.Age_Band ON
Fact.APC_Episodes.AGE_BAND_SKEY = Age_Band.AGE_BAND_SKEY
Group By
Dimension.Age_Band.[10_Year_Age_Band]
I know joining to a view using a column generated by a scalar function is not a good recipe for performance. I also know that I could fix this by populating a physical table with the view first as I have already tested this though I hoping not to have to go down that route.
Why a LEFT OUTER JOIN works and not an INNER JOIN or anyway I can get the query optimizer to generate an execution plan that works?
When I execute this statement through ASP.NET
select cntr_value FROM sysperfinfo
I get this error,
System.Data.SqlClient.SqlException: Invalid object name 'sysperfinfo'. Any ideas why?
I'm running SQL 2000 (SP3) on top of Windows NT 4.0 (SP6).
I have a couple of processes that look at the sysperfinfo table every day to collect some performance/metric type information. It works for all my other servers (mostly SQL 2K/Win2K) except for this one.
Why is the table on this one server empty?
I do have one other SQL 2K/Win NT server. The sysperfinfo table on that one is fine.
the only other clue/difference is that the server which has the empty table is a named instance install of SQL 2K.
Any hints?

I'm running SQL Server 2008 Feb08 CTP and I've got a tablix with column groupings and row groupings which works nicely, I'm a becomming a big fan of the tablix.
However sometimes the filter I have on a column group returns no records and the whole column group disappears.
Is there any way to make this column appear with but with empty cells as I have another tablix down the page with the same columns and I want the columns to all line up on the multiple tablix.
In Version 2005 I used to achieve the equivalent of a column group within a table by adding a list with filter to the cell, this meant the column always was shown, the tablix allows does this much more elegantly but I'll have to go back to the old method if I can't make the column remain.
Am I just missing a simple option?

I would like to capture about 20 rows from the sysperfinfo table every30 secs on a production server. I am thinking of ways I can reduce thedisk (not network) I/O overhead of this process. Instead of readingthe table from a local SQL Agent job and writing to a local table, I amwondering if I should create the job to capture the data from a remote(less critical) server. The servers are connecting via a gigabit lineand are in the same server room on the same switch. This way theproduction server would be required to do the reads but the otherserver could take care of the I/O of the writes to the capture table.Also, this job would run from 7am to 7pm non-stop. A waitfor delay of30 seconds would control the twice a min scheduling. Running this onthe remote server would free up a few SQL Agent CPU cycles as well.This would be one less job for the production server to worry about.Thanks

comparing UNIQUEIDENTIFIER columns..This query returns several rows where the [ReportId] and [LastRunDate] columns are both NULL:
SELECT [c].[Name],[c].[ItemID],[xl].[ReportID]
, MAX([TimeStart]) [LastRunDate]
FROM [dbo].[Catalog] [c]
LEFT JOIN [dbo].[ExecutionLogStorage] [xl] on [c].[ItemID] = [xl].[ReportID]
WHERE [c].[Type] NOT IN (1,5) -- Not a folder or a data source!
group by [c].[Name],[c].[ItemID],[xl].[ReportID]
order by 4
However, trying to just list catalog reports with no execution history returns 0 rows, but I'm expecting it to return a row for every NULL [ReportId] from the above query:
SELECT *
FROM [dbo].[Catalog]
WHERE [Type] NOT IN (1,5) -- Not a folder or a data source!
AND [ItemID] NOT IN (SELECT [ReportID] FROM [dbo].[ExecutionLogStorage])
I even tried casting [ItemId] and [ReportId] columns in the 2nd query to VARCHAR(255), and still got no rows, but the following queries return 0 rows and 1 row (respectively).
select * from [dbo].[ExecutionLogStorage] where [ReportID] = '0BB2209C-7736-46C8-AD02-4614EBA4F0F1'
select * from [dbo].[Catalog] where [ItemID] = '0BB2209C-7736-46C8-AD02-4614EBA4F0F1'
I'm using a performance monitor counter with an alert to catch merge replication conflicts. As you might have seen in my earlier psting this alert keeps running even if all conflicts have been resolved. After almost 2 days searching I found that in the table master..sysperfinfo there all the PM counters are stored still has the value 4 for conflicts/sec. When I manually create a new conflict this value becomes 5 which is nonsense since it's not the number of conflicts per second but the total number of conflicts since I started the server. If I check in PM it shows the correct value, whih of course is zero 99% of the time. Has anybody ever experienced the same kind of problem??
Or does anybody know a way of resetting the values in sysperfinfo. Even after allowing direct updates to systemtables I still can't modify the table.
Thanks in advance

Hi,
The test.sql scripts I write to test CLR stored procedures run successfully, but when I want to display the resulting data in the database with a simple "SELECT * from Employee"
I get the result as:
Name Address
---- -------
No rows affected.
(1 row(s) returned)
But not the actual row is displayed whereas I would expect to see something like:
Name Address
---- -------
John Doe
No rows affected.
(1 row(s) returned)
I have another database project where doing the same thing displays the row information but there doesn't seem to be a lot different between the two.
Why no results in first case?
Thanks,

If I run this statement in Query Analyzer, it properly returns 1for my testing table. But if I put the statement into a storedprocedure, the stored procedure returns NULL. What am I doingwrong? I suspect it may be related to how I defined the parametersfor the stored procedure. Perhaps my definition of TableName andColumnName don't match what COLUMNPROPERTY and OBJECT_ID expect toreceive, but I don't know where to look for the function declarationsfor those. Any pointers would be appreciated.Select statement:SELECT COLUMNPROPERTY(OBJECT_ID('Table1'), 'TestID', 'IsIdentity') ASIsIdentityTable definition:CREATE TABLE [dbo].[Table1] ([TestID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[Description] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]Stored Procedure definition:CREATE PROCEDURE spTest(@TableName varchar,@ColumnName varchar)AS SELECT COLUMNPROPERTY(OBJECT_ID(@TableName), @ColumnName,'IsIdentity') AS IsIdentity
