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 slow
performanc and use a join statement instead.
I want the totals of Amt1 and Amt2 in the TempLimits table added to
each row in the Limits table where the Days in the Limits Table >=
MaxDays in TempLimits
So, when I run the query with the above data
I need to get
************************************************** **************************
Here is the query that I have right now...
update Limit
set 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_Amt2
from TempLimits
WHERE TEMPLIMITS.MAXDAYS <= LIMIT.DAYS
group by limit.relationship_id, limit.product_id
) temptable
on Limit.relid = temptable.relid and
Limit.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 not
work... Is there any way I can do this apart from using temp tables
and co-related subqueries?
I am clear of the funda that first outer query will be executed then Inner query .. but how the comparison is going that is not clear to me plz if any one can help me to understand that.....
My multiple level nested corelated query is not fetching correctresult. It work fine on small set of data, but fails on larger set ofdata. Any clue?Explaining data storing and discussing design would be tough for mehere, still to show you how complex I have created my life, here is thequery:select(SELECT Top 1 RowNSBranchID FROM AssoExtBranchToNSBranchMstM AM-- MMMWHERE AM.RowExtSysID IN(SELECT RowID FROM ExternalSystemMstM WHERE ExtSysID =(SELECT ExtSysID FROM ExternalSystemMstM WHERE SF = 'Active' ANDRowID =(SELECT MAX(RowID) FROM ExternalSystemMstM WHERE MCStatus = 2 ANDExtSysCode = UM.SystemCode)))AND RowExtBranchID IN(SELECT RowID FROM ExternalBranchMstMWHERE ExtBranchID =(SELECT ExtBranchID FROM ExternalBranchMstMWHERE ROWID =(SELECT RowID FROM ExternalBranchMstMWHERE ROWID =(SELECT MAX(ROWID) FROM ExternalBranchMstM WHERE MCStatus = 2 ANDExtBranchCode = UM.UpBranchCodeAND RowExtSysID IN(SELECT RowID FROM ExternalSystemMstM WHERE ExtSysID =(SELECT ExtSysID FROM ExternalSystemMstM WHERE SF = 'Active' ANDRowID =(SELECT MAX(RowID) FROM ExternalSystemMstM WHERE MCStatus = 2AND ExtSysCode = UM.SystemCode))))AND (SF = 'Active'))))AND AM.SF = 'Active'order by AssoID desc,TrackID desc) nsbranchid, UM.*fromTmpInProcessData062005MstM UM

OK, the problem is that if a run the below query in server01, i get error 512:
Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
But, if run the same query in the server02, the query work fine -.
I know that I can use IN, EXISTS, TOP, etc ... but I need understand this behavior.
I am trying to add the results of both of these queries together:
The purpose of the first query is to find the number of nulls in the TimeZone column.
Query 1:
SELECT COUNT(*) - COUNT (TimeZone) FROM tablename
The purpose of the second query is to find results in the AAST, AST, etc timezones.
Query 2:
SELECT COUNT (TimeZone) FROM tablename WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST')
Note: both queries produce a whole number with no decimals. Ran individually both queries produce accurate results. However, what I would like is one query which produced a single INT by adding both results together. For example, if Query 1 results to 5 and query 2 results to 10, I would like to see a single result of 15 as the output.
What I came up with (from research) is:
SELECT ((SELECT COUNT(*) - COUNT (TimeZone) FROM tablename) + (SELECT COUNT (TimeZone) FROM tablename WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST'))
I get a msq 102, level 15, state 1 error.
I also tried
SELECT ((SELECT COUNT(*) - COUNT (TimeZone) FROM tablename) + (SELECT COUNT (TimeZone) FROM tablename WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST')) as IVR_HI_n_AK_results
but I still get an error. For the exact details see:

NOTE: the table in query 1 and query 2 are the same table. I am using T-SQL in SQL Server Management Studio 2008.
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
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.
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.
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.
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...

I have tried various versions of this... begin transaction update StagePayment set Activity = (Select J.JobActivityID from JobActivities J (nolock) inner join StagePayment SP (nolock) on J.JobID = SP.JobID and J.Description = SP.Activity) where Activity is not NULL

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! Thanks in advance! Tiffanie
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.
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?

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

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.
How do you avoid phantom inserts? Can you recommend a strategy (or other posts, articles) to avoid "phantom inserts" with the default SQL Server isolation level ("Read Committed").
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 felicia.schimidt@br.flextronics.com
