Hi,
I am newbie to SQL Server. I am using SQL Server 2000.
I know SQL server compiles the SQL stmt or SP and stores the plan for
later use(I know its not always done. But should be done to reduce
execution time) in memory somewere. I want to capute all the execution
plan which are kept in memory. In oracle v$sql_plan can be used to
access the plan in oracle. I want to know how to do that in SQL Server.
I can use profiler, but it contributes some CPU utilization.
Thanks,
Thiru.

I have one query that executes many times in a week.I created one Maintenances plan that Rebuild all index in my Database thathas been executed at 23:40 Saturday until stop finished at Sunday.However at middle of week (Wednesday or Thursday), that query don’t returnresult like that must be. The time exceeded and the result are total wrong.I compare the normal executed plan and the “crazy” one that SQL create tomount result.The normal is nested with index seek (very fast, the wrong is Merger withhash aggregate (very slow). After Index Rebuild, the executed plan bringresult that must be, but when the merge plan are executed with many updateson that tables (SAM_GUIA_EVENTO and SAM_GUIA), at middle of week, theresult are total wrong, with many rows back.I recommended Index Seek force by coalesce function on one columnaggregate, but everyone here were very panic with that behavior of SQLServer.Please , anyone help me to explain that!Krisnamourt!P.S: Attachments :--Force Index Query with coalesceSELECT count(*)FROM SAM_GUIA_EVENTOS E,SAM_GUIA GWHERE G.PEG=736740AND E.GUIA=coalesce(G.HANDLE,G.HANDLE) AND E.CLASSEGERENCIALPAGTO is NULL--Normal QuerySELECT count(*)FROM SAM_GUIA_EVENTOS E,SAM_GUIA GWHERE G.PEG=736740AND E.GUIA=G.HANDLE AND E.CLASSEGERENCIALPAGTO is NULL--Message posted via http://www.sqlmonster.com
Hi everyone,Does exist an easy way to count the actually number of queries executed within a page?I've searched here and in google but found anything...Thanks in advance!
I had my database in 6.5 which i upgraded to 7.0 using SQL Server upgrade wizard.Then I created full text catalog. When I say incremental population It gives me warning that You can create full text indexes but can not execute queries against it as the database is still in SQL server 6.5 mode.What is the reason behind this?
know if there is any way out to run execution plan for parameterized queries?
As application is sending queries which are mostly parameterized in nature and values being used are very robust in nature, So i can not even make a guess.
In one of our requirement, I want all the query details for the SQL query batch that got executed for the day. I know, we can get sql query from dm_ exec_ query_stats. But I want all sql query along with their session details ie. ExecutedDateTime, SessionId, UserID etc. I have tried using sys.dm_ exec_ sessions. But it contains only last executed query details for all the sessions. how to obtain all the session details for all the query executed for the day in the server.
I created DTS a while ago and placed in job to run once a day (it worked fine for 3 months) 2 days ago I changed sa password and now job fails with error (Login failed for user 'sa'.), but it run fine from DTS !!!
1. My DTS created with domain Account DomainSVCSQL2000( sa rights and local admin) 2. SVCSQL service use DomainSVCSQL2000 to run 3. SVCSQL agent use DomainSVCSQL2000 to run 4. DTS use 'osql -E
Where should look for reference to sa ?
Executed as user: MONTREALsvcsql2000. DTSRun: Loading... Error: -2147217843 (80040E4D); Provider Error: 18456 (4818) Error string: Login failed for user 'sa'. Error source: Microsoft OLE DB Provider for SQL Server Help file: Help context: 0. Process Exit Code 1. The step failed.
Hi Neil, thanks for you advice. The reason I asked the question is because in SQL2000, there was an option which would allow you to export to any file type (including excel). This was done by using the DTS Import/Export interface, does this function exisit in SQL2005Expres? Surely?
Just wonder whether is there any indicator or system parameters that can indicate whether stored procedure A is executed inside query analyzer or executed inside application itself so that if execution is done inside query analyzer then i can block it from being executed/retrieve sensitive data from it?
What i'm want to do is to block someone executing stored procedure using query analyzer and retrieve its sensitive results. Stored procedure A has been granted execution for public user but inside application, it will prompt access denied message if particular user has no rights to use system although knew public user name and password. Because there is second layer of user validation inside system application.
However inside query analyzer, there is no way control execution of stored procedure A it as user knew the public user name and password.
Looking forward for replies from expert here. Thanks in advance.
Note: Hope my explaination here clearly describe my current problems.
I got a mdf file from my co-workerwho just stopped SQL server and delete ldf fileand give me a mdf file.if it was detached, it would work finebut it was just copied.Is there any way to attach this mdf file?I tried sp_attach_db and sp_attach_single_file_dband both failed.thanks,

Hi All, we are changing some reports from English to German...some of the reports that we have changed generate the message 'An internal error occurred on the report server. See the error log for more details.'
I have this report i setup as an agent job in SSMS; It's setup to run every 7 minutes and it only sends the report if data is present. I'd like to add the ability to omit any rows that were sent in the previous report.
This is what the script looks like:
if exists (select o.ord_billto, o.ord_refnum , o.ord_hdrnumber, o.mov_number, o.ord_status, o.ord_cmdvalue, o.ord_startdate from orderheader o where ord_billto in ('A','B','C','D') and DATEDIFF(minute , o.ord_datetaken, GETDATE())<=7
[Code] ....
Also, why I can't seem to use IF ( Select [...]) > 0? When i try using that instead of IF EXISTS i get this error: "Msg 116, Level 16, State 1, Line 7 Only one expression can be specified in the select list when the subquery is not introduced with EXISTS."
I am creating a report where there are 3 tables in one report which have visibility set as an expression so that when a certain criteria is selected in the "Report" parameter, a different table is shown below. Â This works as expected.
When table 3 is shown, I want a new parameter to be visible to the user called "Ward" where the user will select the ward they are interested in and the table will display data below just for the ward selected.  However, I don't want the ward parameter visible when either of the other 2 options are selected. Is this possible and how to do this?Â
We have a debate in our team about embedded SQL vs. Stored Procs.
The argument is why use SP's if you can embed the SQL in the code and SQL2K will cache it on the fly?
I can't find any definitive information on pros and cons between the two methods.
If there are no major performance issues, or gotchas, I guess it comes down to developer preference.
SP Pros: - Great SQL support in VS.NET (dev, debug, integration) - Seperation of database specific code from middle tier. - Less lines of code in middle tier - VS.NET support for .xsd dataset definitions. - Logic closer to data for more demanding processes.
Embedded SQL Pros: - Less artifacts for version control - Better encapsulation of logic
I am working on tuning the procedure cache hit ratio for my server. We haveadded 4 Gb of memory to the server, which has helped. In addition, I have runthe DBCC FREEPROCACHE, which helped for a couple of days to get the hit ratioup to about 84% (from 68%).When I use the performance monitor on the server and look at SQL Server CacheManager:Buffer Hit Ratio, I see that the Prepared SQL Plan is around 97%, butthe Procedure Plan hit ratio is down around 55%. I've done some research ondifferent tuning techniques, but can't seem to find 1. a clear definition ofthe difference between the prepared sql plan and the procedure plan and 2.other than adding memory and running dbcc freeprocache, how can I get theprocedure plan cache raised? I do know that there are some procedures thatneed to be modified to be called fully qualified (e.g. exec dbo.sp_###instead of exec sp_###), but I don't think that those will increase theprocedure plan by 30% or more.Any insight you can give would be greatly appreciated.Thanks,Michael--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200511/1
The benefit of the actual execution plan is that you can see the actual number of rows passing through each step - compared to the estimated number of rows.But what about the "cost percentages" ?I believe I've read somewhere that these percentages is still just an estimate and is not based on the real execution.Does anyone know this and preferable have a link to something that documents it?Thanks
Hi, this code inserts twice the same record. I thing it is due to the "Selet Scope_Identity" in the sqlcommand.If i remove the Select part, the inserts occurs only once. If i remove the line "comd.ExecuteNonQuery()", then the inserts also occurs once. Is there something wrong in my code? ThanksT. Dim connection As SqlConnection Dim comd As SqlCommand Dim connectionstr, sql As String Dim iden As Integer connectionstr = ConfigurationManager.ConnectionStrings("econn").ConnectionString.ToString() connection = New SqlConnection(connectionstr) comd = New SqlCommand() comd.Connection = connection sql = "INSERT INTO table(field,...) VALUES (@fld,...); SELECT SCOPE_IDENTITY()" comd.Parameters.Add("@var1", SqlDbType.NVarChar, 10).Value = txtvnm.Text ... connection.Open() iden = Convert.ToInt32(comd.ExecuteScalar()) comd.ExecuteNonQuery() connection.Close()
I know you can use sql profiler to see what sqlcode actually executed when you run a sproc, but is there any way toget this information in asp.net? After executing a sproc, I'd like to send the sqlcode that was sent, to my Audit class. Is there any wayto retrieve this in asp.net itself?cheers!
I created a simple DTS which executes a VB standard exe that simply writes a string to an ascii file opened as append. SQL Server, the exe, and the ascii file are all on the same NT box (mine). If I execute the DTS myself the process works with no problems. When I attempt to execute the DTS via a job the job hangs with no apparent indications as to what may be the cause of the hangup. The SQL Server Agent is up and running and set to run under the system account. I have applied SQL Server SP3. The same problem was occuring prior to applying SP3.
Does anybody have any idea? All sugestions are appreciated.
Is there any (easy!) way in which I can see the SQL that has been executed. I'm using stored procs that create & execute other stored procs(via sp_executesql). At the early stages there are often trivial errors in the created procs that cause rather general exception messages that do not give much of a clue as to where the error is. (It's tedious to find these in the debugger) ... and was wondering if there's any trace output type option I can turn on to see what sql has been presented for execution.
Hello, i have a trigger and i want to know the query that raised it, or want to retrieve the last executed query by the server. I think it's a hard question but i know that someone can help me... Thanks
hello, I have a big problem with a script.. some instructions seems to be not executed. I don't understand. If I execute line perline it's ok - but the entire block no. Explain me and find the solution:
IF NOT EXISTS ( SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'ACS_ACL' AND COLUMN_NAME = 'ZoneUId' ) BEGIN
ALTER TABLE dbo.ACS_ACL ADD ZoneUId T_UID;
UPDATE dbo.ACS_ACL SET ZoneUId = '1' WHERE ZoneUId IS NULL;
print 'end of script'
END
result:
Msg 207, Level 16, State 1, Line 9 Invalid column name 'ZoneUId'.
the error is on line: UPDATE dbo.ACS_ACL SET ZoneUId = '000000001' WHERE ZoneUId IS NULL;
I have a program that allows various users to login to the sql server. On the login window there is a dropdown that lists all the databases on the server and the user can select which database they wish to login to. To get the list of databases on the server I use a login created for the program we will call 'worker'. The program logs in as worker and runs "SELECT * FROM sys.databases". Before I load the login window, I check to make sure the login worker exists or has been corrupted (in case a user deletes it or changes the password, etc) and if it has been corrupted or deleted, I recreate the login using the "CREATE LOGIN worker WITH PASSWORD = '123' " function.
The problem occurs after I recreate the worker login. The login is created successfully but when the login window appears and logs in as the worker login to get a list of the databases, I get an error saying the login failed for worker. If open the login window again, everything works fine (the worker login isn't created again as it already exists). Further, if I run the same code but put a break point in the code and step through everything, it works the first time.
Is there an amount of time that is necessary to wait for the CREATE LOGIN function to be executed?
I have a SQL 2000 DTS package which executes without errors when run from the DTS design screen or by right clicking the package and selecting execute. When I schedule the package and get it to run at a certain time or highlight the job and select start, the package comes back with an error saying there was a problem with a transformation. I have tried scheduling the DTS by right clicking on it and selecting schedule and creating a new job and using DTSRun with an operating system command. I get the same results! Help!
I have a DTS Package that is used to dispatch mails to all the customers. When I execute the package manually by selecting it and then clicking Execute Package from the context menu, it executes to completion successfully. But when I schedule to execute it using Job, then I get the following error message:
... DTSRun: Executing... DTSRun OnStart: DTSStep_DTSExecuteSQLTask_2 DTSRun OnFinish: DTSStep_DTSExecuteSQLTask_2 DTSRun OnStart: DTSStep_DTSActiveScriptTask_1 DTSRun OnFinish: DTSStep_DTSActiveScriptTask_1 DTSRun OnStart: DTSStep_DTSExecuteSQLTask_3 DTSRun OnError: DTSStep_DTSExecuteSQLTask_3, Error = -2147220421 (8004043B) Error string: The task reported failure on execution.

FYI: This Package is under machine7. When I copy the package to my system (machine3) and execute it using Job, it succeeds :rolleyes:
Using the dm_exec_query_stats in 2005, I know I can get the number ofexecutions for a particular sql_handle, but is it possible to get thenumber of execs for a SQL in version 7 or 2000? Also is it possible toget reads/writes/etc in these early versions?Thanks.
Hello -I am trying to determine the last time a SP was executed. Does anyoneknow how to do this? I'm trying to cleanup some databases.Thanks!*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
