I currently have a series of stored procedures that capture stock prices on a daily basis, then summarize the results into a daily, and further, a weekly summary of the "index" of a group of stocks. The data is accumulated from a (to use a highly technical unit of measurement...) bunch-O-individual rows of data using aggregate functions such as AVG and SUM.
The problem is that I occasionally get a warning on such aggregate statements which is the common one complaining thusly: "Warning: Null value is eliminated by an aggregate or other SET operation"
I know where it comes from, and I know how to code to protect the aggregate from complaining (i.e., AVG(ISNULL(yadayada,0)) ) but I am interested in figuring out a way to REPORT the statement that contains null values. I can, of course, capture ERRORS in selects, but is the same mechanism used to capture these NULL warnings on my aggregate statements? I don't necessarily want to know which individual row is causing it, just want to "tag" somehow the statement that results in the warning so I can go back after the run and check into it (after capturing local "pointer" info at the time the offending aggregate is invoked).
The code I use to capture errors and trace information follows:
UPDATE PortfolioPerformance
SET PrevDate = @PrevDate,
DailyPerChg = GPP.DailyPerChg,
DailySumPriceChg = GPP.DailySumPriceChg,
SumCurrPrice = GPP.SumCurrPrice,
SumPrevPrice = GPP.SumPrevPrice,
StockCount = GPP.StockCnt,
AvgHighPriceRatio = GPP.AvgHighPriceRatio,
AvgLowPriceRatio = GPP.AvgLowPriceRatio,
Volume = GPP.Volume
FROMPortfolioPerformance PP (nolock), VIEW_Get_PortfolioPerformance GPP
WHERE PP.PortfolioID = GPP.PortfolioID AND
(PP.CreateDate = GPP.CreateDate AND
PP.CreateDate = @CreateDate) AND
PP.PrevDate IS NULL
NOTE: the aggregation in the above code is performed in the view referenced as "GPP", but that's outside the realm of the question, I think, so I won't bore you with the details of that just yet.
So I think if I can capture the warning like I do the errors, I can accomplish what I want to accomplish. I haven't yet been able to find any guidance in the Books Online, so do any of you have any pointers?
i have replication setup and working, there are 3 subscribers and now i want to add a 4th one. is it ok if i just add the subscriber and reinitialize replication?
Hi,We have a Java application that runs against a variety of backendsincluding Oracle and MSSql 2000 and 2005. Our application has ahandful of active tables that are constantly being inserted into, andsome of which are being selected from on a regular basis.We have a purge job to remove unneeded records that every hour "DELETEFROM <tableWHERE <datafield< <sometimestamp>". This is how we arepurging because we need 100% up time, so we do so every hour. Forsome tables the timestamp is 2 weeks ago, others its 2 hours ago. Thedate field is indexed in some cases, in others it is not... theDELETE is always done off of a transaction (autoCommit on), butexperimentation has shown doing it on one doesn't help much.This task normally functions fine, but every once in a while theinserts or counts on this table fail with deadlocks during the purgejob. I'm looking for thoughts as to what we could do differently orother experience doing this type of thing, some possibilities include:- doing a select first, then deleting one by one. This is apossibility, but its SLOW and may take over an hour to do this so we'dbe constantly churning deleting single records from the db.- freezing access to these tables during the purge job... our appcannot really afford to do this, but perhaps this is the only option.- doing an update of an "OBSOLETE" flag on the record, then deletingby that flag... i'm not sure we'd avoid issues doing this, but its'an option.The failures happen VERY infrequently on sql2005 and much morefrequently on sql2000. Any help or guidance would be mostappreciated, thanks!Bob
I need to first capture the max version associated with a file name here is the meat
SELECT fileName, f.folderName, masterID, iterationId, iterationNumber version FROM fileIteration fi JOIN iteration i on (i.iterationID = fi.fileIterationID) JOIN vw_folderFileLink fl on (fl.fileMasterID = i.masterID) JOIN folder f on (f.folderID = fl.folderID)
WHERE fileName LIKE '429020652.idw' --GROUP BY masterID, fi.FileName, f.FolderName, fileName, i.iterationID ORDER BY masterID, version DESC --*******end code ********--
First I need help just getting that top row but then I need to get all expect the top row selected.. I've tryed using MAX in several ways but I'm not getting what i want here :/ any help is appreciated
How do I format a date value in SQL 2000 sp? Tired the following none are returning the quivilent rates. What is the syntax please? SELECT *FROM tblCompanyWHERE ( C_LastBuyDate = '03/21/2008') SELECT *FROM tblCompanyWHERE ( C_LastBuyDate = '2008/03/2008') SELECT *FROM tblCompanyWHERE ( C_LastBuyDate = '03-21-2008')
I am new to .NET, after many years with classic ASP I am struggling a little with something that I am sure is really easy to do.
Basically what I want to do, is execute an SQL statement, that will return a single value. I then need to store this value as a variable, so that I can pass it into another query later.
It seems easy to output the record, but how do I store it as a variable !!
This is my code to connect and run the SQL... all I need to do as retreive the value, and put it aganist a variable....
Function higher_manager_ein() As System.Data.IDataReader

Is there any way(other than Profiler) to capture a full SQL Query statment. I've used dbcc inputbuffer and the current activity screen, both return 255 characters. I'd like to capture the whole query. Thanks
I have what OUGHT to be a simple question...or so I think (which really hurts, mind you...)
I am writing a stored proc that will reside on several different databases and be used to write a row to a "wait table" that is used to control processing in the various databases...
Essentially, the stored proc already exists, and writes what is essentially a note (or process semaphore) that says "Hey, Process XYZ is waiting on the completion of process 123"
Problem is...process XYZ has the same name on a number of different servers, so I have to come up with a way to differentiate the process name that's waiting on a job on a single server (in other words, 5 or more XYZ's can be waiting on a single job on a single server in the network, and the wait table resides on that single server).
So...my thought (again, think pain) is that I will put a process name of "SERVER.XYZ" into the wait table.
The SP I will use to write the "waiting on" semaphore is a common one, so - long story short(er) I need a way to capture the name of the current server (like db_name(), only server_name() - or something like it).
I have to import data into 2 tables on a daily basis. The data is provided as a flatfile. In order to fullfill this task the tables have to be truncated first. Are there any possibilities to do this job automatically with dts, or do I have to write an Interface in VB or something like that?
hello guys ! i need a little help in an update statement.
i have two tables as
table1(id1,name) table2(id2,date,val2)
what i want is to set val2=45 in table2 where date=4/4/2007 (say) and id2, now id is to be obtained from table1 based on the name;
like table1 --------- (1,"akmal") (2,"peter") (3,"kamal")
I know the name as peter, but i want to used its id1 (2) in the update statement. You might have got the idea that id2 is a foreign key referring to id1.
Hi All I am using following code for my application SELECT convert(varchar(10),acr._eventTime,120) [Date], sum(case r.Severity WHEN 'Warning' THEN 1 end)[Warning], isnull(sum(case r.Severity WHEN 'OK' THEN 1 end),0)[OK], FROM ActiveCheckIssueResult r GROUP BY convert(varchar(10),acr._eventTime,120)
it gives me Result as,
Date warning OK --------- --------- ----- 1/1/1008 1 1 2/1/2008 0 2
i want count on weekly basis Could any one help me?
I want to set my job agent to schedule for second basis but in EM i found by right clicking job in EDIT Recuring Job Schedule i m getting option in Hr and MM but not in SS so where i can set this in seconds (SS) or through QA????
Currently database1 and database2 are planned to be synchronized with the interval of 5 seconds!! ( dont know exact, but i select run continoulsly on subscriber screen ) This could cause serious performance issues as both applications will be live on difference servers.
how can i Synchronization should be performed on day basis or it should be modification basis to avoid any performance issue on live application
i am using merge replication Local distributor and subscriber on another server .
I'm just a newbie with XML. Now we're moving all our DTS to SSIS packages. Most of them are simply processes that takes a plain file and loading these data into Sql table or in inverse way. So that I wonder what role will play XML here.
I mean, are there big differences between store data as XML format and nvarchar?
I have a bit of code that executes an INSERT statement to add a record to an existing table. This table of course has an automatically incrementing ID field, and I'd like to somehow have my INSERT statement return the value of that ID field so that I can automatically show the user the record they've added.
This doesn't work because the first INSERT is creating multiplerecords for multiple projects. @@IDENTITY, then, contains the Identitycolumn value for the last tblWeekReportedLine record inserted.Consequently, all the hours records are then associated withthat last value.The source work table, #EstimateLines, is a pivoted representationwith a Begin/End date and some Hours for each of six periods - a lineper project that gets pushed up to the DB by some VB code.Definition below the sample coding.The "@WeekReportedID" value was successfully captured whenprevious coding inserted six records into that table: one foreach date range (i.e. column in the UI screen)Sounds like I'm approaching this wrong.Suggestions on the right way to go about it?---------------------INSERT INTO tblWeekReportedLine(WeekReportedID,RelativeLineNumber,ProjectID)SELECT@WeekReportedID1,#EstimateLines.RelativeLineNumber,#EstimateLines.ProjectIDFROM#EstimateLines;SET@CurWeekReportedLineID = @@IDENTITY;INSERT INTO tblHour(WeekReportedID,WeekReportedLineID,HoursDate,Hours,HoursTypeID,HoursType,TaxCodeID,TaxCode)SELECT@WeekReportedID1,@CurWeekReportedLineID,@BeginDate1,Estimate1,@DummyHoursTypeID,@DummyHoursType,@DummyTaxCodeID,@DummyTaxCodeFROM#EstimateLines;------------------------The #Temp table create via VB:------------------------1030 .CommandText = "CREATE TABLE #EstimateLines " & _" ( " & _" PersonID int, " & _" ProjectID int, " & _" RelativeLineNumber int, " & _" Available1 decimal(5,2) Default 0, Estimate1decimal(5,2) Default 0, BeginDate1 DateTime, EndDate1 DateTime, " & _" Available2 decimal(5,2) Default 0, Estimate2decimal(5,2) Default 0, BeginDate2 DateTime, EndDate2 DateTime, " & _" Available3 decimal(5,2) Default 0, Estimate3decimal(5,2) Default 0, BeginDate3 DateTime, EndDate3 DateTime, " & _" Available4 decimal(5,2) Default 0, Estimate4decimal(5,2) Default 0, BeginDate4 DateTime, EndDate4 DateTime, " & _" Available5 decimal(5,2) Default 0, Estimate5decimal(5,2) Default 0, BeginDate5 DateTime, EndDate5 DateTime, " & _" Available6 decimal(5,2) Default 0, Estimate6decimal(5,2) Default 0, BeginDate6 DateTime, EndDate6 DateTime, " & _" );"--------------------------PeteCresswell
I'm trying to add functionality to a VB 6 application allowingcustomer service to add a customer number to a new customer.Customers are added to the database by sales personnel, and aprospective customer may have multiple rows due to projected ordersfor multiple products. Customer numbers are assigned when a newcustomer makes their first order.I'm using a DataGrid connected to an ADO Data Control. The datacontrol is connected to a view in SQL Server using the 'distinct'directive (I know it's not updatable) to show only one line per newcustomer. What I wish to do is capture the update event (probablythrough the FieldChangeComplete routine of the data control), manuallyassign the newly entered customer number to all appropriate rows inthe database, and cancel the update event with no notifications.I'm having two problems:1. I can't capture the newly entered customer number. The Textproperty of the DataGrid returns the old value of the cell instead ofthe newly entered value. How do I get the edited value?2. Even though I set adStatus = adStatusCancel in theFieldChangeComplete routine, I get a Microsoft DataGrid Control dialogstating 'Operation was Canceled'. How do I avoid this notification?
When running an SSIS Package from BIDS, we get to see the "Progress" tab which explains us the progress of the SSIS Package. During production, is there any way to capture this log. I am interested in using this as a log file for each run of my SSIS package.
I've just been reading this thread by a guy asking about capturing the throughput of a dataflow. I suggested that there is no real notion of capturing throughput of a dataflow but I believe there IS a notion of capturing the throughput of a component or an execution tree.
I believe all the information that one would need to capture the throughput of a component (apart from the name of the component that is) is available in the OnPipelineRowsSent event. If there were a OnPipelineRowsSent eventhandler and the OnPipelineRowsSent event contained the name of the component then I think we would be able to capture the throughput of a component. So, some questions:
Why is there no eventhandler for the OnPipelineRowsSent event?
Can the name of the component be added to the information in the OnPipelineRowsSent event?
Following on from this... I once had a conversation here with Kirk Haselden about capturing pipeline throughput. He thought it was a good idea and suggested I raised a DCR for it which I did but that was in the old pre-Connect days and it seems as though that DCR (like SO many other things) didn't make it across to Connect. So, some more questions:
Can you find any Connect DCRs relating to capturing throughput? I've found this: https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=152162 that I raised 18 months ago but which hasn't even had a single comment from anyone at Microsoft.
Do you think that capturing throughput would be useful? I can foresee huge advantages by capturing this in the debugger. (Note that Informatica does this and has done for years. It has a very nice GUI that shows the throughput of each destination in the mapplet.) I'd welcome any thoughts around this. Its a big ask and it fits in very nicely with my constant, nay INCESSENT, requests for debugging enhancements so maybe this is one for Darvey to have a read of???
I inherited an application that creates reports and each report pulls data from a SQL database. The reports are for each School district in the state and pull the number of students that have Asthma conditions, simple enough. However what happens is this... Each initial report is saved with a code of 2 for initial. As long as there aren't and revisions I am fine. If a school makes a revision (Code of 4) I now have two records in the database and I need the one from the revision (Code 4). Not every record will have a revision, and sometimes there may be multiple revisions. How can I code my stored procedure to go through the database and check to see if there is a code of 4 or multiple codes of 4 and if so grab that data, if not grab the initial data? Below is the code currently being used. Frank

On a webpage, there are filters to choose from. Like date, amount, SSN (multiple filters can be choosen).I have a single query so far. SqlCommand cmd = new SqlCommand("SELECT [column1], [column2], [column3], [column4], [column5] FROM [table] WHERE [column4] = 'condition4' AND [column5] = @total_bill AND [last_change] >= @txtStartDate AND [last_change] <= @txtEndDate ", Conn) ; cmd.Parameters.Add(new SqlParameter("@total_bill", total_bill1.Text)); cmd.Parameters.Add(new SqlParameter("@txtStartDate", txtStartDate.Text)); cmd.Parameters.Add(new SqlParameter("@txtEndDate", txtEndDate.Text)); I want to break the query so that it executes on the basis of different sets of conditions (filters). If I dont select date filter, then the above query will not execute properly.Please help.
I have recently upgraded one of our servers using the in place upgrade method to SQL Server 2005 from SQL Server 2000.
We are currently having an issue with stored procedures as they appear to be running slowly and the only way to correct this issue is to recompile them on a daily basis.
Has any one else had a similar issue, any ideas what could be causing this to occur.
How would you solve this problem? Would you use replication? SSIS? Schedule stored procs? A third party data tool?
We have about 50 databases located at offices around the world. There are several key tables which we need a central copy of at our Head Office.
We need only the new INSERTS or UPDATES for the day to be copied to head office. The copying process should happen after business hours for that office.
Some cleaning of the data needs to happen before updating head office.
Our database is being installed at new offices every other month, so it's important to us that this be easy to add a new database into the schedule, ideally without needing a SQL DBA or Developer.
We want something robust, performant and easy to troubleshoot.
On what basis, SQL server decides the sequence of these rows?
I need to fetch data from a table with very large number of rows. Because of the datasize I need to do this in chunks. I am thinking of passing row counter and fetch N rows at a time. I want to know if there is a need for sorting a table before I apply the above logic or I can rely on default sorting.
I'm creating a sproc to to count the dates and times users log on to a page. I want the date and time broken out into two columns. When I attempt create the sproc I get the following error: Subqueries are not allowed in this context. Only scalar expressions are allowed.Create PROCEDURE [dbo].[LoginCounter]
@Username Nvarchar(50), @IPAddress Nvarchar(50), @BuilderID, INT
As
INSERT INTO LoginCount ([UserName], [IPAddress], [Date], [Time], [BuilderID])
I would like to analyze how a particular 3rd party business application interacts with SQL server.
Specifically, I want to capture the "exact" SQL commands (transact-sql statements) that this application issues whenever it completes an operation for the user of this application.
In other words, suppose the application issues the SQL command "INSERT INTO table (a,b,c) values (1,2,3)" to add a new entry to the database. Then, my understanding is that if I instead issue the exact same command with a tool like "SQL query analyzer", the database will be updated in the exact same manner. Hence, I have effectively accomplished the same job that the 3rd party application does without even using it (by idependantly issuing the same command to the database it uses).
Is this possible? Can I obtain all the information I need just by running SQL Profiler?
Hi, Can someone help me out with capturing the bulk insert error.I have a job which calls a procedure in which I used the bulk insert command .If the bulk insert is failing due to some reason as wrong delimitor,wrong path etc then the job fails.I need to track that error and see that the job doesnt stop and goes onto the next cursor record. Thanks, Nodbek
I'd like to capture the avg. # of user logins and # db hits per a 5 interval for a weeks time. I'm guessing there are sys tables containing this info. and by using temporary tables and/or creating/modifying SPROCS this info. can be retrieved. If I'm on the right track, a little direction would be very appreciated. If I'm not on track, please assist this rookie dba.
I currently have a need to dynamically build an sql statement that always returns a single value when executed. The sql statement is always the same except the database name reference in the statment.
What I need is to be able to capture that value for later use in the procedure. Since this is a stored procedure, I can't use the "USE" statment to switch databases and I haven't been able to figure this out using the Execute statement. I can execute the string, but I can't capture the value.
I'm simply trying to execute the same set of sql statements in a stored procedure without hardcoding database names or build an identical stored procedure in all our databases.
