Sysperfinfo Table Empty
Jul 15, 2004
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?
Regards,
hmscott

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?

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:

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

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

All, Using access 2003 frontend and sql server 2008 backend. I have an append query to insert 80000 from one table to an empty table. I get an error:
"Microsoft Office Access set 0 field(s) to Null due to a type conversion failure, and didn't add 36000 record(s) to the table due to key violations, 0 record(s) due to lock violations, and 0 record(s) due to validation rule violations."
I know this error normally comes if there are dups in a field that doesnt allow.

I am creating three tables in a DataSet using three stored procedures and I need a way to know that either the tables have at least one row or preferably which if any has no rows. How can I do that?
using three SP's, one for each table:SqlCommand cmd = new SqlCommand("CompanyCheck", con);SqlCommand cmd2 = new SqlCommand("ContractorVerify", con);SqlCommand cmd3 = new SqlCommand("StoreLocation", con);
cmd.CommandType = CommandType.StoredProcedure; cmd2.CommandType = CommandType.StoredProcedure; cmd3.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@CompanyID", CompanyID); cmd2.Parameters.AddWithValue("@CompanyID", CompanyID); cmd3.Parameters.AddWithValue("@CompanyID", CompanyID); SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd; DataSet ds = new DataSet(); try { da.Fill(ds, "CompanyInfo"); da.SelectCommand = cmd2; da.Fill(ds, "ContractorInfo"); da.SelectCommand = cmd3; da.Fill(ds, "StoreInfo"); } catch { throw new ApplicationException("Data error"); } finally { con.Close(); }
Thank you

I have a particular production database that on a few recent occasions has suddenly had one of it's tables empty of content. Now there are no jobs or triggers in place neither is any stored procedures that could perform a delete or alter table operation in place. The permissions have been set not to allow this either. The datatype is text only. What is intriguing is the QA server has an exact mirror and this dosen't happen. Has anyone come across this sort of phenomenon?

I can use the Design Table option in every database and any user table on my server except for two databases which were transfered from a SQL 6.0 server.
I can't even use Design Table to create a new table in these databases. I get the Design form up and it allows me to add columns, but when I try to save the changes I get the following error message:
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'full'.
[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'full'.
One thing I have noticed is under Users for the database, all my users come up as 'via group membership' for the Database Access column for the database I am having problems with. All other databases the users come up as 'Permit' for the Database Access column. I assume this has to do with security. But I have tried everything to change this. I can not get a user to come up as 'Permit' under these two converted databases.
Does anyone have any ideas?

Hi,can somebody explain me, why the IDENT_CURRENT from an empty table is 1?After insert of the first record it is still 1 (assuming that start valueis 1) which is okay. But if i check the IDENT_CURRENT from a newly createdtable the result should be NULL, or not?bye,Helmut

In Access I have a macro that, each night, takes a table with aprimary key defined in it, and deletes all the rows. Then itimports/appends records from a fixed width text file. In this way,since the table is not deleted and recreated, the primary key is keptintact.What would be the equivalent SQL method for doing this in an automatedway? I've tried letting DTS import the table from Access, but theprimary key is lost. Is there some way to "empty" a table instead ofdropping it, and then append new records so that the table will end uphaving the primary key I want it to have?Thanks.Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake.

When i try to insert new rows using SSIS into an emty table in my database, SSIS freezes. The same happens when i use a lookup on an empty table.
The only solution i have found is to manualy insert a row and remove it afterwards. When i have done this SSIS works without a glitch.
I start off by taking a script of a existing database and applying this script on a new database. So that i create an empty duplicate of my current database.
Any ideas why SSIS freezes? Do i have to initialize something first in my database? It is really annoying that i have to insert a row and delete a row into every table i want to use.

Hi,
I'm using the Business Intelligence Studio for designing reports in VS2005 with SQL-Server 2005 Standard used on a TFS server.
On my report I have several tables each related to a previously defined dataset. Now, if a dataset returns no data, I would expect, that the table shows the header but no rows. This is true, if the table is located on the first page of the report and used directly in the preview tab of a report project. If such a table is located on following pages, I get an rsInternalError when switching to the second page. Trying to export the report, e.g. pdf, directly results in this error. When trying to view the report on the report server, the error appears also at once.
If, in Visual Studio, clicking on the button "page layout" everything is fine: empty tables are shown correctly.
How can I avoid this error in my reports? I would like to publish my report (no fancy stuff, just simple text data), possibly containing empty tables, on the server that all team members can view it - without the error...
Thanks in advance,
Erik Steiner

I am trying to work with a developer test a code change in their application. The db basically has a workload table and as it finishes processing each row in the table, it gets deleted from the table. I want to monitor when the db becomes empty/no rows in it to test how much the code changes have worked, how long does it take to process all rows in the table. Any quick way to do it at the db level instead of having to put something in the code just for this testing.

Hi,
I was wondering what the best way was to deal with subscriptions breaking due to an empty table. I have subscriptions that people have scheduled to go out daily, but on certain days the table may be empty, in this case the subscription doesn't read the parameters for the report and then the subscription breaks.
My original solution involved creating a #temp table with the same columns as the original table and inserting one row into it which I'd union with the original table, this row in the temp table had all its values set to 0. The solution worked when I ran it in SQL Server Management Studio but it seems SRS doesn't like the INSERT INTO statement, which is the error I get, but I've read on these forums that it doesn't like #temp tables either. I proceeded to use a stored procedure with all the code in it, but I might have trouble filtering on multi value parameters, because at times these parameter lists get real big, plus I have to do this for multiple reports and don't want to get into creating stored procedures for each report.
Following is what the code I used look something like that executes and does the job in Management Studio but not SRS. I'm mainly just looking for the easiest and cleanest way to do this, since it'll have to be done across multiple reports, so disregard the code if there's an easier way to do it. Thanks in advance.

Hello,I'm a beginner in SQL and I have been searching through the SQL Cookbook and Google but I can't seem to find an example of what I want to do. I want to create a report that will return names and emails using two of my tables. I want to use the email in my primary table in the select but if it is null or empty I want to replace it with an email from my secondary table. Below is what I would like to do but I got a syntax error with it in SQL Server 2000. SELECT MemberID As ID, MemberFirstName As FirstName, MemberLastName As LastName, (IF MemberEmail = '' THEN SELECT TOP 1 OtherEmail FROM OtherTable WHERE OtherID = MemberID) As EmailFROM PrimaryTableThanks for your time.Jason

I have a column within a table which is already truncated/deleted all records within (Microsoft SQL 2008). I have to now populate the column with sequential numbers up to 50,000 records arbitrary numbers (doesn't mater) up to 7 characters.
what SQL statement I need to write that will automatically polulate the newly empty table with A000001,A0000002,A0000003, or any form for that matter etc so that I can sort number the records within the table.
I have approximately 50000 records which I need to sequentially entered and I really dont want to number the column manually via hand editing.

I've built a simple VS2005 ASP.Net web app that uses Crystal Reports for generating assorted reports. More specifically, when a report is called it executes the correct SQL Server Stored Procedure and returns a Data Table populated with with appropriate data. In my testing, everything seemed to be working fine.But I just did a test where I pressed the "Submit" button on two different client browsers at almost the same time. Without fail, one browser returns the report as it should but the other one returns an empty report; all of the Crystal Reports template info is there but the report is just empty of data. Considering that each browser is running in its own session, I'm confused about why this is happening.One thing: I did login as the same user in both cases. Might this be causing the problem?Robert W.Vancouver, BC

Hi all,
In BOL it says: "The Lookup transformation performs an equi-join between values in the transformation input and values in the reference dataset. Using an equi-join means that each row in the transformation input must match at least one row from the reference dataset. If there is no matching entry in the reference dataset, no join occurs and no values are returned from the reference dataset. This is an error, and the transformation fails, unless it is configured to ignore errors or redirect error rows to the error output. "
I have a lookup transformation which is supposed to find a match on two fields in the reference dataset (a table in my case) but strangely, when I execute my package and the reference table is empty the lookup still finds match for each row of my input dataset.
Does anyone have an idea why? I could'nt find anything about that in BOL.
Sébastien.

I have created some dynamic sql to check a temporary table that is created on the fly for any columns that do contain data. If they do the column name is added to a dynamic sql, if not they are excluded. This looks like:
If (select sum(Case when [Sat] is null then 0 else 1 end) from #TABLE) >= 1 begin set @OIL_BULK = @OIL_BULK + '[Sat]' +',' END
However, I am currently running this on over 230 columns and large tables 1.3 mil rows and it is quite slow. How I can dynamically create a sql script that only selects the columns in the table where there is data in a speedier manner. Unfortunately it has to be on the fly because the temporary table is created on the fly.

Damn! SQLServer2000 can't add a NOT NULL COLUMN even in one emptyexisting table!That is, A is the existing table and it is emtpy, I want to add one NOTNULL COLUMN (col_new) to A using following T-SQL statement, then itwill fail.ALTER TABLE A ADDcol_new varchar(600) NOT NULLGOYou should change it to these statements in SQLServer2000:ALTER TABLE A ADDcol_new varchar(600) NULLALTER TABLE A ALTER COLUMN col_new varchar(600) NOT NULLGOah, ridiculous! right?Fortunately, this stupid behavior is changed in SQLServer2005. Thefirst T-SQL statements works.

I have a report that has 3 graphs and two tables that render to 5 pages in pdf. Some users should only get a subset of the 5 elements and some need all 5. When I set the Hidden property (in the designer or via a parameter) for any of the elements they become invisible but in pdf but the report still prints out a page for the hidden element. It works fine in the designer and rendered to html and excel but I get an extra page in pdf. it is like the hidden element still takes up the same amount of space but is just hidden.
Any help would be great.
