CPU Bottlenecks? -- Gurus' Help Needed
Aug 10, 2001
QUESTION 1:
I am getting high DPC utilization in Performance Moniter. What is DPC
(seems to be CPU bound). How can I tune my system to be use this resource?
QUESTION 2:
Is the equation below correct?
Total elapled time = cpu + memory + disk + network + program time
According to query analyzer, my elapsed time is ie 100
BUT my cpu and disk time totals only 20. Where is the rest of the
elapsed time coming from??
Thanks

I have a problem.. My code below works fine but when I want to add user to the database, it gives me error.
I added this part
u = Membership.GetUser(User.Identity.Name)
nice = u.ToString()
and it gives error here

Probably this will be a silly question?
1. How can I Put all the Q documents from Microsoft that are related to SQL server? So that I can search fast.
2. How can I search SWYNK for all the ANSWERS that MAK/CRAIG/RAY replied to the threads. Its so weird that I answered someone and now I forgot the answer what I posted. Now I am having the same problem. I cant search.
3. I wanna put all SWYNK's Questions responses in one database say SQLSERVER, so that I can search all the threads.
I had sent many emails to SWYNK. No reply so far.
Any inputs r well appreciated!!!!!!

To find the disk bottlenecks, we need disk read per sec, disk writes per sec, avg. disk sec per read and Ave. disk sec per write.
When we were monitoring disk I/O:
We got min. disk reads per sec, max. disk reads per sec and avg. disk reads per sec.
I think we have to take max. disk reads per sec to calculate the total physical I/Os per disk, but i am not sure....
Please anyone can help me
Thanks a lot

I am about to heavily index a table and have to include atleast 3 to 4 olumns in the fulltext index for this table.
The table is updated very frequently and the also the columns that are involve in the fulltext indexing undergo frequent updates.
As of now, I can't avoid using full text indexing as these columns are very very lengthy and basically contail text.
The users of the database will give some key words as the search criteria
to get infomation as to what they are looking for.
How frequently should I update my full text catalog.
This is a scenario where the full text is operating on various tables and
each of thses table might be containingaround 300,000 to 800,00 rows.
I would appreciate an intelligent siggestion as I need it as soon as possible.
Thanks and have a wonderful time ahead.

My boss has a crazy idea that he want to implement using SQL 2005 and ASP.NET 2. Its something like this... If a user retrieve a record and someone is updating that same record a control on a asp.net page would warn that user that its being updated. Just like a stop light, green for go, yellow for warning, and red for stop. Were implementing optimistic here not pessimistic. Is this possible? I know pessimistic can lock that certain record. But what about in optimistic? Is it possible to monitor or know if a certain record or row in SQL 2005 is being access, updated, and deleted? How?

I have 2 tables :
tab1 col1 char(10), col2 char(10), col3 char(10)....Primary key on col1+col2
tab2 col4 char(10),col5 char(10),col6 char(10)......Primary key on col4+col5
I want to insert a row from tab2 if its not there in tab1.
And I want to update col3 of tab1 from col6 of tab2 if col1+col2 matches col4+col5.
Any thoughts on doing these 2 tasks. I am sure these will be 2 differnet commads.

Hi,I have a table in which two fields(FirstID, SecondID) together make theprimary key for the table. Let's look at the following example:FirstID SecondID******* ********2 22 32 55 55 78 79 1011 12Here is what I am trying to do. For a given FirstID (say, 2) find allSecondID with this FirstID (2,3,5). Now for these second ID's is therea FirstID other than 2? (Yes, 5). I would say FirstID=2 is related toFirstID = 5. Extending the logic FirstID = 5 is related to FirstID = 8.I am trying to write a SQL (some kind of self join, I think) which willgive me all related FirstID for a given First ID. For First ID = 2 theSQL will give me 5 and 8 in the above example. For First ID = 9 the SQLwill give me 11.Any help will be greatly appreciated. Thanks!!-Raj

We need to return the results of a query as a single string.For example if the query returns 10 rows,all the 10 rows should be concatenated and put it in an output @returnstring. Is that possible in SQL stored procedures ??

SQL Server Load Balancing -- Any ideas?
There is no inherent mechanism available in SQL Server (replication, log shipping, or clustering) which allows you to load balance you database server.
Clustering is only useful for a failover situation and does not allow active/active balancing.
Is is possible to use merge replication between two identical OLTP servers
and manage transactions via MSMQ? Will this mechanism allow for a load balanced OLTP server?
Will this work? If not, why not?
What will work? Will federated servers work for an entire database??

I need to determine the differences between two tables with the same structure. The primary key for these tables would be a combination of all the columnhs. They use the ID field to join all their records. (i know ID is a reserved word - the client made the tables) Below is the structure of the tables.
TableA
and
TableB
----------
ID int
ComBank int
inboth int
EqorMA int
TranType int
I need to know the rows that Are different in TableA from TableB.
Any help would be appreciated.
Thanks

Hi there!
I'm trying to insert a MSWord/Bitmap/Powerpoint file into a table in SQL 2000. Unfortunately, I haven't had the luck to get it work. Here is my table structure :
Create table tbl_blob (
doc_id varchar(20) not null,
doc_blob image null )
My question is, do you have any script on how I can insert a MSWord/Bitmap file in my blob table. I will be running the script using Query Analyser.
thanks!

i realize i am starting to ask a lot of questions here so, thanks to all who tolerate me.
In my previous post, i figured out (with the help of r937) how to create a non-identity column using a cursor. I now have some resulting questions.
1. where do cursors live? there is no folder like triggers or stored procedures. is a cursor its own file or is it embedded in a stored procedure?
2. how do i get my cursor to "act" upon my stored procedure? I want the values in my cursor's "relativeposition" column to replace the values in my stored procedure's photo_number column. how do i do this?
BELOW IS MY STORED PROCEDURE:
Code:
ALTER PROCEDURE dbo.sp_NewPersonalPic
(
@photo_name VARCHAR(50) = NULL,
@photo_location VARCHAR(100) = NULL,
@photo_size VARCHAR(50) = NULL,
@user_name VARCHAR(50) = NULL,
@photo_caption VARCHAR(150) = NULL,
@photo_default BIT = NULL,
@photo_private BIT = NULL,
@photo_number INTEGER = NULL,
@photo_date DATETIME = NULL
)
AS
BEGIN
SELECT @photo_date = CONVERT(DATETIME,convert(char(26), getdate(), 109))
END
--SET ANSI_WARNINGS OFF
INSERT INTO PersonalPhotos
(photo_name, photo_location, photo_size, user_name, photo_caption, photo_default, photo_private, photo_number, photo_date)
VALUES (@photo_name, @photo_location, @photo_size, @user_name, @photo_caption, @photo_default, @photo_private, @photo_number, @photo_date)
--SET ANSI_WARNINGS ON
END
RETURN
AND HERE IS THE CURSOR:
Code:
DECLARE RelativePositionCursor
CURSOR LOCAL FAST_FORWARD FOR
SELECT photoId, photo_date
FROM PersonalPhotos
ORDER BY photo_date ASC
OPEN RelativePositionCursor
DECLARE @curs_id INT
DECLARE @curs_date DATETIME
DECLARE @totalRows INT
DECLARE @firstRow INT
SET @firstRow = 0
DECLARE @Results TABLE
(
curs_id INT NOT NULL PRIMARY KEY,
curs_date DATETIME,
RelativePosition INT
)
FETCH NEXT FROM RelativePositionCursor
INTO @curs_id, @curs_date
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @totalRows = (SELECT COUNT(*) FROM PersonalPhotos)
WHILE(@firstRow <= @totalRows)
BEGIN
SET @firstRow = @firstRow + 1
BREAK
END
INSERT @Results
VALUES (@curs_id, @curs_date, @firstRow)
FETCH NEXT FROM RelativePositionCursor
INTO @curs_id, @curs_date
END
CLOSE RelativePositionCursor
DEALLOCATE RelativePositionCursor
SELECT *
FROM @Results
ORDER BY curs_date

The Scenario:We have some data that can be in three states. One is a saved state,a temporary state, and a complete state.The complete state is the bulk of the data. This data will berequested 1% of the time, maybe even less.The saved state and temporary state will only number 10-15 records.This data will be used 99% of the time, very frequently.So to summarize there will be 10-15 records that will be used ALL thetime…. And 50,000-100,000 that will be used very infrequently.The programmer that I work with wants to combine the tables. I wantto keep the tables sepperate.My logic is that it will be much faster to work with 10-15 recordsthan sift threw 50-100k most of which are unnecessary to 99% of therequests. Also there are frequent deletions/modifications in thetemporary table(10-15 records). The complete table can NOT havemodifications or deletions (50-100k records). The optimization forthese tables is also very different.He says that since the structures are almost identical they should bein the same table, that we should just use a field to denote thedifferent types of records. He insists that my view is wrong and thatI know nothing about databases.I may be new to SQL, but am I really that out to lunch? Would it notmake sense to keep these tables separate?(Thank you for taking the time to read this)Sat

Greetings All,
I have a SQL2005 table that I'm needing to export to a 'formatted' csv flat-file to emulate a mainframe output. I'm new to SSIS so don't beat me up to bad... The current output of my ssis csv file is as follows:
95752,95725,0001,0, ,N
11473,8704,0001,0, ,N
1279215,436612,0001,0, ,N
43595,43592,0038,0, ,N
and I need to get to here:
95752 ,95725 ,1 ,0 ," ","N ",0
11473 ,8704 ,1 ,0 ," ","N ",0
1279215 ,436612 ,1 ,0 ," ","N ",0
43595 ,43592 ,38 ,0 ," ","N ",0
Basically I need to pad the first 2 columns with trailing spaces to a fixed width of 11 characters, 3rd column convert number format and pad to fixed 5, 4th column pad to fixed 3, 5th column add double quotes around 20 character fixed. 6th column add double quotes around and pad to fixed 2. Finally adding a , 0 to each row which is used a LF/CR.
Any feedback in regards to getting pointed in the right direction would be greatly appreciated...

ORDER by BuddyID

the query above will give me the BuddyID for about 75 records. I want to join the BuddyID on the "Buddies" table to the BuddyID on the "Users" table. I just don't know where to put "INNER JOIN Buddies ON Users.BuddyID = Buddies.BuddyID"

Hello!
I have push transactional replication to set up.
I have 2 publisher’s servers with tables, which replicate data in the same table on subscriber.
Tables on both publishers already have data.
When I set up replication between first publisher and subscriber
Snapshot of existing data was done, so I didn't miss any data from the
First publisher table.
But I don't have idea what to do with second publisher, because if I
will make snapshot it will overwrite the data have been replicated from
First publisher. If I won't make snapshot I will miss already existing data
in second publisher.
I have headache. Can you help me to resolve the problem?
Thanks a lot in advance,
Elena

4 days ago we had a Server crash luckily we have the daily full database backups...Since the server which was crashed is unusable I installed SQL 7.0 on another machine...I tried to restore databases from our backup tapes...Here is the T-SQL I am running:
restore database pentatel from tape='.ape0' with file=2,move 'PentaTel_dat' TO 'D:mssql7datapentatel.mdf', move 'pentatel_log' to 'D:mssql7datapentatel.ldf'
The error message I am getting is:
Processed 8992 pages for database 'pentatel', file 'PentaTel_dat' on file 2.
Processed 1 pages for database 'pentatel', file 'PentaTel_log' on file 2.
Server: Msg 9004, Level 21, State 1, Line 1
The log for database 'pentatel' is corrupt.
Connection Broken
After these when I look at the SQL Enterprise manager I see that the database is in loading status...I left it in that status for hours but there was no reaction...So I tried to detach and attach a single file.Here are the TSQLs and Error messages...
exec sp_attach_single_file_db pentatel, 'd:mssql7datapentatel.mdf'
Server: Msg 945, Level 14, State 2, Line 1
Database 'pentatel' cannot be opened because some of the files could not be activated.
Server: Msg 1813, Level 16, State 2, Line 1
Could not open new database 'pentatel'. CREATE DATABASE is aborted.
We have 7 backups and I tried all of them...Same error messages...
When I try to change the status from loading to emergency or normal the database is always inaccessible
I are running these statements
exec sp_configure 'allow',1
reconfigure with override
update sysdatabases set status=32768 where db_id=6
and I stop and start the Mssql7 service but still inaccessible
Any idea???
I despretaly need help...Any recomendation is greatly apreciated...

We are new to SQL 2000, and would like to bounce a couple questions off some of you gurus out there.
We are using SQL Server 2000 to build a data repository to assist us in transitioning from our old flatfile legacy system to SAP. We are also looking to use the SQL Server 2000 repository to build a smallish Enterprise Data Warehouse on the same SQL 2000 platform.
Here is our problem:
We have SQL Server 2000 loaded on a little scrapper PC with 1.4GHZ single processor, 1GB of memory, and a single 40 GB IDE drive.
When we are initially loading any of our repository tables the process cruises along pretty well, even respective of trying to locate the record for update before doing an insert. But, if we do something as simple as selecting count(*) against the table that's loading, performance on the load goes to its knees.
We understand we're pretty much at the mercy of the hardware we have (that's the budget), but we'd like to get as much bang as we can out of what's there.
Our questions are:
1. Is there anything we can do with our server configuration (short of new hardware) that will help us?
2. Are there any recommendations as far as monitors to help us better tune this specific configuration?
Thanks in advance for any help.

Can you guys help me out with a TSQL statment to display the output of a table like this.
Required Output :

x002 x003
x003 x004
Input Table

No temp table or variable should be used. Only an TSQL statement.

Hi,
I am positive some SQL Gurus can help me with this complicated query. I am not sure if it is possible with a single query or needs multiple queries.
I have 3 objects. First, PaintOrder; Second, Combination; and Third, Material. Each Paint Order can have multiple Combinations and each Combination can have multiple (from 0 to 5) Materials. All the data is stored in single table called paintMatCom.
Here is the sample Data
PaintOrderId CombId MaterialId
1000 1 1
1000 1 2
1000 2 3
2000 1 1
2000 2 3
2000 2 4
3000 1 1
3000 1 2
3000 2 3
3000 3 4
3000 3 5
I have a Search Screen where user can select multiple Materials (upto 5) to search for the appropriate PaintOrders. Also, use has the option to select AND/OR between materials. Please look at the attached image for clear understanding.
Some of the sample searches are as follows (Combination IDs are not needed in the Output; just PaintOrder IDs).
1. Find PaintOrders with MaterialIDs 1 AND 2 OR 4
2. Find PaintOrders with MaterialIDs 2 OR 3 OR 4
3. Find PaintOrders with MaterialIDs 3 AND 4 OR 5 OR 1
Hope you got the idea. I think it would require some Joins and GROUP BY which I am not expert at. I would appreciate any help.

Here's what I have come up with so far ... if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[fn_FirstDayOfMonth]') and xtype in (N'FN', N'IF', N'TF'))drop function [dbo].[fn_FirstDayOfMonth]GOif exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[fn_LastDayOfMonth]') and xtype in (N'FN', N'IF', N'TF'))drop function [dbo].[fn_LastDayOfMonth]GOif exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[fn_LastWorkingDayOfMonth]') and xtype in (N'FN', N'IF', N'TF'))drop function [dbo].[fn_LastWorkingDayOfMonth]GOif exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[fn_WorkingDaysBetweenDates]') and xtype in (N'FN', N'IF', N'TF'))drop function [dbo].[fn_WorkingDaysBetweenDates]GOif exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[usp_PopulateTimeSeed]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)drop procedure [dbo].[usp_PopulateTimeSeed]GOif exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[TimeSeed]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)drop table [dbo].[TimeSeed]GOSET QUOTED_IDENTIFIER ON GOSET ANSI_NULLS ON GOCREATE Function fn_FirstDayOfMonth (@SearchDate datetime)Returns DatetimeasBegin Declare @ReturnDate datetime Select @ReturnDate = CalendarDate from TimeSeed where CalendarYear = Year(@SearchDate) and CalendarMonth = Month(@SearchDate) and DateOfMonth = 1 Return @ReturnDateEndGOSET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS ON GOSET QUOTED_IDENTIFIER ON GOSET ANSI_NULLS ON GOCreate Function fn_LastDayOfMonth (@SearchDate datetime)Returns DatetimeasBegin Declare @ReturnDate datetime Select @ReturnDate = Max(CalendarDate) from TimeSeed where CalendarYear = Year(@SearchDate) and CalendarMonth = Month(@SearchDate) Return @ReturnDateEndGOSET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS ON GOSET QUOTED_IDENTIFIER ON GOSET ANSI_NULLS ON GOCreate Function fn_LastWorkingDayOfMonth (@SearchDate datetime)Returns DatetimeasBegin Declare @ReturnDate datetime Select @ReturnDate = Max(CalendarDate) from TimeSeed where CalendarYear = Year(@SearchDate) and CalendarMonth = Month(@SearchDate) and WorkingDayFlag = 1 Return @ReturnDateEndGOSET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS ON GOSET QUOTED_IDENTIFIER ON GOSET ANSI_NULLS ON GOCREATE Function fn_WorkingDaysBetweenDates (@SearchDate1 datetime, @SearchDate2 datetime)Returns intasBegin Declare @CountDate int Select @CountDate = Count(CalendarDate) from TimeSeed where CalendarDate >= @SearchDate1 and CalendarDate <= @SearchDate2 and WorkingDayFlag = 1 Return @CountDateEndGOSET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS ON GOCREATE TABLE [dbo].[TimeSeed] ( [CalendarDate] [datetime] NOT NULL , [DateOfMonth] [int] NOT NULL , [DayOfMonth] [varchar] (12) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [CalendarMonth] [int] NOT NULL , [CalendarYear] [int] NOT NULL , [FiscalYear] [varchar] (9) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [FiscalMonth] [int] NOT NULL , [WorkingDayFlag] [bit] NOT NULL , [WorkingHours] [int] NOT NULL , [WeekOfYear] [int] NOT NULL , [WeekOfMonth] [int] NOT NULL ) ON [PRIMARY]GOALTER TABLE [dbo].[TimeSeed] WITH NOCHECK ADD CONSTRAINT [PK_TimeSeed] PRIMARY KEY CLUSTERED ( [CalendarDate] ) ON [PRIMARY] GO CREATE INDEX [IX_TimeSeed] ON [dbo].[TimeSeed]([DateOfMonth]) ON [PRIMARY]GO CREATE INDEX [IX_TimeSeed_1] ON [dbo].[TimeSeed]([CalendarYear]) ON [PRIMARY]GO CREATE INDEX [IX_TimeSeed_2] ON [dbo].[TimeSeed]([CalendarMonth]) ON [PRIMARY]GOSET QUOTED_IDENTIFIER ON GOSET ANSI_NULLS ON GOCreate Procedure usp_PopulateTimeSeedasDeclare @StartDate datetimeSelect @StartDate = '19000101'Set DateFirst 1While @StartDate <= '21001231'begin insert into TimeSeed ( IntDate ,CalendarDate ,DateOfMonth ,DayOfMonth ,CalendarMonth ,CalendarYear ,FiscalYear ,FiscalMonth ,WorkingDayFlag ,WorkingHours ,WeekOfYear ,WeekOfMonth ) Select Cast (@StartDate as int) ,@StartDate ,Day(@StartDate) ,Datepart(DW,@StartDate) ,Month(@StartDate) ,Year(@StartDate) ,Case When Month(@StartDate) <= 3 Then Year(@StartDate) - 1 Else Year(@StartDate) End ,Case When Month(@StartDate) <= 3 Then Month(@StartDate) + 9 Else Month(@StartDate) - 3 End ,Case When Datepart(DW,@StartDate) in (1,7) Then 0 else 1 End ,8 ,Datepart(wk,@StartDate) ,(Day(@StartDate)%7)+1 Select @StartDate = Dateadd(dd,1,@Startdate)EndGOSET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS ON GO Here's what has me stumpedI'd like to calculate the hours difference for a given start and end datetime in SQL server. Certainly function datediff() can do the job but the tricky part is that the hours calculation should be based on 8 hrs / per business day (from 8:00am to 5:00pm), and weekends (Saturdays and Sundays) are excluded as well. For example:start time: 11/10/04 4:00pmend time: 11/11/04 8:00 amthen the hours difference should be only 1 hour. (if there is fraction, then round to nearest hour). Now ... remember that the table TimeFeed is modifiable and can be changed to suit our needs. Any ideas ??? Also ... you can all chip in with your own functions ...

Hi Guys, first time posting here. My boss has a Lotus Notes application accessing SQL server with about 60 users. I have a custom VB app with 40+ users. Our SQL Server has
2 gigabyte of memory on it. Is this too low? My boss is expecting to have 300+ users on his Notes app when he rolls it out to our other branches. What would be the ideal amount of memory for 300+ users?

I want to create an MS Access front-end for my SQL database.
I want to create user accounts with passwords for each user.
Should I change SQL Server to "MIXED authentication mode" (SQL Server authentication and Windows authentication) ?
