To Avoid Fragmentaion
Jun 25, 2001
I found some fragmented data pages in my database tables.
I have found out using DBCC Showcontig commands.
I want to remove data fragmentation.
My tables are replicated. Is it possible to remove fragmentation
without using export and import. Please help me in fixing this problem.
Is there any way to fix replication failure with out recreating it.
My replication has failed saying is timout error.error is could not connect
subscriber. But I can able to ping the subscriber and if I create a new publisher and subscriber it is working fine. But existing one is not working.
What might be the possible reason. We have recreated the replication. We droped the existing one and recreated it. It took around 14 hours to sync.
Is there any way to resync with out recreate publication. We are using transaction replication and merge replication.

Hi All,I am working on Web Application which deals with history data forreports and keeping track of changes.Current Solution :1) For each Entity I am having a column TID (Tracking ID) whichkeep on increasing for an instance of Entity. (so history and presentdata in the same table) . It makes querying the data difficult.2) I am also using month year table for Managing data i.e<TableNameMMYYYY> for a given month and yearPurposed Soluion :1) Using a seperate table so that history and present data isplaced seperately .2) Store All data in one table <TableName>Please guide me on advantages and disadvantages you pin point in thetwo approaches.With warm regardsJatinder

Hello,
I have the following query,
SELECT GroupInfo.GroupID, GroupInfo.GroupName
FROM GroupInfo INNER Join DeviceGroup ON(DeviceGroup.GroupID=Groupinfo.GroupID)
INNER Join Deviceinfo ON (Deviceinfo.SerialNumber=DeviceGroup.SerialNumber )
It's out put is as follow:
Group ID GroupName
0 Abc
1 Beta
0 Abc
0 Abc
0 Abc
1 Beta
2 Alpha
Now, I want to make such query which will give me result as a Group ID and Group Name but not in repeating manner, Like,
Group ID GroupName
0 Abc
1 Beta
2 Alpha
Hope I explained what I need to see in result pane.
Thanks,
Junior

In out web application it happens very rarely that same query gets executed more than once meaning that sp_executesql is degrading performance. Does anyone know a way to tell ADO.NET to stop encapsulating queries in sp_executesql? Thank you.

Hi All,
Very Ad-hoc requirement I am having.
I've got one table with two columns.
Column Name Data Type
1) Id Integer Identity
2) RemDate DateTime
I've to write one SP/JOB in that there will be an integer input parameter @numofday.
Say value of @numofday is 5 then.... in SP/Job I need to insert 31 - 5 = 26 records to above-mentioned table where date starting from 1st of current month.
This logic can be achieve through looping but if anyone can suggest some better way to achieve this functionality without use of looping.
Thanks in advance,
Jai

Happy new year to all! Now a question...
I added a new column to StagePayments table - Activity - which is supposed to end up being the same as the JobActivityID from the JobActivities table. Basically, I need to get JobActivities (JA) info and put it in the StagePayment (SP) column. Problem is there are duplicate JA/Descriptions and SP/Activities, so what I need is to take the first sequence SP/Activity and grab the first JA/JobActivityID that matches for a particular JobID. Then get the next one of each and so on and so on...

way too basic as I get this error...

I know somehow I have to get the duplicate Activities in the same sequence as the Descriptions, but that's where I'm stuck?!?
If anyone is able to offer suggestions on how to get this to update correctly, I'd be very happy to hear about it!

Hi,
I need to query a database for a recordset and insert this into another database row-by-row.
For each record I want to provide a time of insert, but for each insert this time has to be incremented by 1, the time format is HH:MM:SS.0000 so for each inserted record the last decimal point would increment by 1.
Can I do this without a cursor ?
Any additional info I will provide gladly.
Thanks!

I am conducting stress testing for my website and keep getting deadlocks with the following message when one process is adding about 100 records per second and another process is trying to access the data:
Transaction (Process ID 499) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
What do I need to do in my stored procedures to avoid this? I only have ONE stored prcoedure that locks a row while incrementing an ID value. I am not doing any other locks, so is this a SQL Server system lock?
Any advise would be much appreciated. Thanks!

Application is a Work Tracking/Timesheet database.The increments of work are stored in the TimesheetItem table. Thiscontains, inter alia, the Work Code, the Start and the Duration thatthe employee spent that day on a particular project.Some employees in the Network Support Department don't complete astandard 7.5 hour day for various reasons, so for every Network Supportperson I need to update these particular days with an amount to bringthe total day's hours to 7.5.This SQL will get me a list of all TimesheetItem records for thepersonnel concerned.SELECTTimesheetItem.TypeID,[Work].WorkCode,TimesheetItem.Start AS Start,SUM(CAST(TimesheetItem.DurationMins AS float) / 60) AS HoursFROMTimesheetItem LEFT OUTER JOIN[Work] ON TimesheetItem.WorkID = [Work].WorkIDWHERE(TimesheetItem.EmployeeID IN(SELECT EmployeeID FROM Employee WHERE DepartmentID = 2))GROUP BYTimesheetItem.TypeID, TimesheetItem.Start, [Work].WorkCodeHAVING(TimesheetItem.Start >= @FromDate) AND (TimesheetItem.Start <= @ToDate)ORDER BYTimesheetItem.StartWhat I need is to group these records by EmployeeID where theaccumulated hours per day are < 7.5, so that I can then insert anincrement to make up the difference.I'm writing this from home and I don't have access to the tables toprovide a script, but there's nothing untoward there.Hope someone can help!ThanksEdward

Hi, all!
Having a table with a varchar(10) column, I try to insert a row where the data for that column is more than 10 characters long. No surprise, I get a MSG 8152 error.
What I want is to get the overlong data clipped to the maximum column width, and no error. Is that possible?

Hi everyone,
As first task I've got Data Flow which loads a set of data into a .NET recordset.
After that, inmediately flow execution goes to For..Each Loop. I'd like to avoid go in that direction when Data Flow returns zero rows.
How can I do such thing?
I've tried this on Precedence Constraint Editor but it doesn't work..It doesn't recognize EOF keyword..
@[User::ResulSet] == EOF
Thanks in advance for your input,

I have to admit, I'm usually using the MySql database, but in this particular case I have to use MSSQL 2000.
Over to my problem.
I'm building a web-based system (who isn't these days) in which the user types arbitrary information that is published when the user pushes the save button. Nothing new about that.
Here comes the tricky part, when the user wants to edit an existing item I copy all information in the database and sets the id of the 'edit-copy' to the negative value ( id 45 becomes id -45 for the edit-copy). This is also done on all items in other tables that is connected to the main item.
This way I get a copy that the user may edit without messing up the published information. When the user is done I either delete all the negative items (cancel) or delete the positive items and update the negative to become positive (save).
So far so good, allmost... my problem is that the transaction log grows tremendously.
Is there any other way to accomplish a safe edit that doesn't affect the transaction log as much as my current solution?
Could I be doing something wrong when updateing or deleteing my items?

hate to gripe, but this was bad. I have taken several sql server classes over the years, and have always been happy with the class, but avoid the 2733a (upgrading you database administration skills to sql 2005). Class is poorly devloped and incomplete. Half of the examples were to do things such as mirroring and replication from a command prompt. I thought I was in an Oracle 8 class. It was clear much of this functionality is not complete. In fact most of the class was command prompt based. They had absolutley nothing about the upgrade process from SQL 2000 to SQL 2005. I hope MS is not taking a step backwards, I always thought the strong suite for MS was the enterprise manager tool suite. The instructor did tell me there was an upgrade to the class that just came out, but it has a long way to go.

Hello All,
I have faced a network problem during some days, what forced one of our replications to be stopped.
The Publisher database is a high volume database.
After I re-started the replication, the Subscirber database has its transacting log size increased quickly, because of the high volume of information to be inserted.
My concern is the way it is working, there will be no enough space for the log or for its backup files.
So, I have created a TSQL job within the following commands:
BACKUP LOG database_name
WITH TRUNCATE_ONLY
DBCC SHRINKDATABASE (database_name,TRUNCATEONLY)
It's running every 20 minutes, however the transaction log remains increasing.
I have also changed the db_option "SELECT INTO/BULKCOPY" to TRUE, in order to avoid logging bulk copies, but I believe, it didn't work because it didn't apply to replication process.
Does Anybody know if I can disable the transaction log or avoid this incresing of size during the replication?
Thanks a lot!
Regards,
Felicia Schimidt

I have some SQL scripts for SQL Views and getting divide by zero error. I am using
COALESCE(Field1,Field2,1)/COALESCE(Field3,Field4,1)
This function can avoid NULL but how I can avoid 0 ?
Is there any function in SQL that can take care both NULL and 0 and replace it with 1.

I have a query that maps all products to some customer levels. In this case levels 0,5,7 and 8
DELETE FROM ProductCustomerLevel
WHERE CustomerLevelID IN (0, 5, 7, 8)
INSERT ProductCustomerLevel
(
ProductID,
CustomerLevelID
[Code] ....
Basically this maps all products in a database to these customer levels so that they get a discount.
I know need to create a new customer level, example number 9. These will only have 1 or 2 products applied to it.
How can I change the SQL above so that it does not map those products already in Customer Level 9 to levels 0,5,7 and 8

Hi,
I have a customer who is using vba to pull a result set from an sql server stored procedure into excel. She wants a calculated column added to the result set that gives:
The number days (datediff) between the end date (autend_dte) on one row and the begin date (autbeg_dte) on the next row for each client (clt_num). The rows are to be ordered by client and begin date. The number should be associated with the second row used to calculate the date diff. The first row for each client will have a date diff of 0.
I could do this using a cursor in the stored procedure or a loop in the vba, but I would prefer to do it with the select, but I don't even know where to start.
See expected results below.
CREATE TABLE #testit (
clt_num int NOT NULL ,
autbeg_dte datetime NULL ,
autend_dte datetime NULL)
INSERT INTO #testit (clt_num, autbeg_dte, autend_dte)
SELECT 510, '2004-09-01 00:00:00.000', '2005-09-30 23:59:00.000' UNION ALL
SELECT 510, '2005-10-01 00:00:00.000', '2006-04-06 23:59:00.000' UNION ALL
SELECT 600, '2006-08-01 00:00:00.000', '2006-11-06 23:59:00.000' UNION ALL

Hi All,
i have a table as below
create table temp
(
Number int,
DateError datetime
);
insert into temp values(13,' ');
i get
Number DateError
------------------
13 1900-01-01 00:00:00.000
Now, i want "1900-01-01 00:00:00.000" and just want NULL or blank and ofcourse not 1900-01-01 00:00:00.000 for my further processing.
I have a problem, i have to formath string send it as second value which is simple ' '.
How can i modify my Table definition above to achieve this.
Thanks in advance.

Hi,
Please help with the below deadlock problem :
We are using SQL Server 2000. Our application is a J2EE based. We use Java v 1.5 ,EJB 3.0 ,JBoss-4.2.0 and have sqljdbc.jar v 1.1 driver (to connect to sql server from jboss).
We have a JMS Queue which is unloading a java.util.List object at a time. This List has 5 value objects.
In the session bean I iterate through this list and do the following :
while(importListPeople.hasNext()){
Person value = (Person)importListPeople.next();
//select statement to check if the Person already exists in DB
Person prsn =entityManager.query("SELECT from Person where...");
if(prsn !=null){ //do an update if person already exists
// update person record
// update PersonAV table
// do an insert into personIndexingQueue
// increment the person update counter.
}else{//do a create
entityManager.persist(value);
//insert into personAv table
//do an insert into personIndexingQueue
//increment the person create counter.
}
}
I get the below error when we are running the application
13:04:41,904 WARN [JDBCExceptionReporter] SQL Error: 1205, SQLState: 40001
13:04:41,904 ERROR [JDBCExceptionReporter] Transaction (Process ID 63) was deadlocked on {lock} resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
For log ,sqlprofiler I could narrow down that the deadlock is occurring on the below select statement in the code.
//select statement to check if the Person already exists in DB
Person prsn =entityManager.query("SELECT from Person where...");
This code works if there is only one object in the list.
The above code works on mysql with 20 objects in the list.
Please help.

I have a table that I cannot create a unique key for because there is nothing unique and I can concatenate anything together to create one. I am looking for a way to import the data daily and have it only import what is not already in the table like a unique index would normally do. I don't want a sequencial number because that would do me any good. I need the record only in there once but I want to get all of the records in the new table. I have a date field with this if that at all helps. I am wondering if I could create a couple of feeder table to make this work but i am stuck. Any ideas on what to do? Thanks!!!

I need help on two questions:1. Is temp table the only way to pass recordsets from a nested storedprocedure to a calling stored procedure? Can we avoid temp tables inthis case?2. Are operations in a stored procedure are treated as a transaction?Any help will be greatly appreciated.Background: We need to use temp table to pass recordsets from a nestedstored procedure to a calling stored procedure. Our understanding isthat in this case, we have no choice but to use temp tables. So, weneed to optimize the performance as much as possible. To do this, wewanted to find out whether operations in a stored procedure are treatedas a transaction. We are using SQL 2000 SP4. I could not find anyanswers so I did the following experiment.Experiment 1:SET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS OFFGOif exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[Wiz_SP_Transaction_Test]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)drop procedure [dbo].[Wiz_SP_Transaction_Test]GOCREATE PROCEDURE [dbo].[Wiz_SP_Transaction_Test]ASUpdateArticlesSETIsUpdate = 20whereArticlesId < 80000SELECT * from ArticlesGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGO"SELECT * from Articles" takes a long time (about 40 seconds) tocompleteBefore executing the SP, the IsUpdate attribute for all articles is 30.Then I executed this SP. Before the SP is finished, I end the SPmanually. I checked the IsUpdate attribute again, and found that allArticles's (ArticlesId < 80000) Isupdate attribute is now 20. Theoperations did not rollback. I interpret this to mean that the whole SPis not treated as a transaction.Then, I did experiment 2 below. This time, I explicitly declared thetransaction.SET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS OFFGOif exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[Wiz_SP_Transaction_Test]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)drop procedure [dbo].[Wiz_SP_Transaction_Test]GOCREATE PROCEDURE [dbo].[Wiz_SP_Transaction_Test]ASBEGIN TRANSACTIONUpdateArticlesSETIsUpdate = 50whereArticlesId < 80000SELECT * from ArticlesIF @@ERROR <0 ROLLBACK TRANSACTIONCOMMIT TRANSACTIONGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGOBefore this second SP, the IsUpdate attribute is 20 (set in the firstexperiment). I run this second SP and ended it manually before itfinished. I checked the IsUpdate attributes for all Articles's(ArticlesId < 80000), but their Isupdate attribute is 50. So theoperation did not rollback either. But we have declared the transactionexplicitly. Does this mean that the SP is still not treated as atransaction?

Hello,I have a situation which would essentially use a co-related subquery.I am trying to avoid using a co-related subquery due to its slowperformanc and use a join statement instead.Here is what I am trying to do:Tables:========Limit-------RelID ProdID Days Amt1 Amt2----- ------ ---- ---- ------148 2 30 15000 30000148 2 7 1000 2500Temp Limits-----------RelID ProdID MaxDays Amt1 Amt2----- ------ ----- ------ ------148217500 10001482717500 5001482302500 200014829025000 75014821807500 -300I want the totals of Amt1 and Amt2 in the TempLimits table added toeach row in the Limits table where the Days in the Limits Table >=MaxDays in TempLimitsSo, when I run the query with the above dataI need to getRelID ProdID Days Amt1 Amt2----- ------ ---- ------ ------148 2 30 42500 (15000+7500+17500+2500) 33500(30000+1000+500+2000)148 2 7 26000 (1000+7500+17500) 4000(2500+1000+500)************************************************** **************************Here is the query that I have right now...update Limitset Amt1 = isnull(Amt1,0) + IsNull(temptable.temp_Amt1, 0), Amt2 = isnull(Amt2,0) + IsNull(temptable.temp_Amt2, 0)from Limit inner join(select Templimits.relationship_id relationship_id,Templimits.product_id product_id, sum(Templimits.Amt1) temp_Amt1,sum(Templimits.Amt2) temp_Amt2from TempLimitsWHERE TEMPLIMITS.MAXDAYS <= LIMIT.DAYSgroup by limit.relationship_id, limit.product_id) temptableon Limit.relid = temptable.relid andLimit.prodid = temptable.prodid************************************************** ****************************As you would see here, I am trying to use the condition for Days(listed in the query in CAPS) inside the inner query which would notwork... Is there any way I can do this apart from using temp tablesand co-related subqueries?Thanks in advanceKannan

Hi, I having a problem with my query...
I want to copy data from 4 different database to 1 database... but if the destination database have already the same Primary Key the copying stops/terminated and not copying others that is not yet in the destination...
I don't have knowledge in T-SQL like IF...ELSE
my database is SQL Server 2000 but i'm using SQL 2005 Express Management for the query...
What i'm doing is like this:
Use osa (Destination Database)
Go
DELETE FROM tblFaculty (*I'll delete first the datas to avoid duplication)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM cislucena.dbo.tMasFaculty)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM amapn.dbo.tMasFaculty)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM abe.dbo.tMasFaculty)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM aclc.dbo.tMasFaculty)
My problem is if the facultyID (PrimaryKey) which i'm copying is already on the destination which is osa, the copying stops/terminated regardless whether there is more to copy. On the 4 source database, there might data that other database also has. That's why the copying is terminated. All i want to do is to check first each FacultyID if it is already on the destination before copying it to avoid error or duplication of Primary Key so it won't terminate the copying.
How is this possible sir? Anyone care to help? Thanks in advance! More Power!
Best Regards
