I'm trying to get the execution plan for a single stored procedure
from Profiler. Now, I've isolated the procedure but I get all
execution plans. Any ideas on how to connect the SPIDs so that I only
get the execution plan for the procedure I'm watching and not the
whole of the server?
i have a few stored procedures called by an application that i would like to create execution plans for every time they are run. is there a way to do this? or are execution plans only done through the Sql Server Query Editor? these queries make comparisons between a temp table and a master table and setting up the data for the tables is time consuming. so id like to automate it by setting the store procedure to create the execution plan at runtime.
View 2 Replies View RelatedIs it possible to check query execution plan of a store procedure from create script (before creating it)?
Basically the developers want to know how a newly developed procedure will perform in production environment. Now, I don't want to create it in production for just checking the execution plan. However they've provided SQL script for the procedure. Now wondering is there any way to look at the execution plan for this procedure from the script provided?
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

Hello :
How to execute a procedure stored during execution of the report, that is before the poster the data.
Thnak you.
Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes
I have a stored procedure that I want to test for performance , however, I cannot view the estimated query plan execution. I am not using any nested subqueries. Any ideas why the plan will not generate?
Thanks in advance!
hi
how can i execute the stored procedure statements in asp with c#.net ?
Is there a way that a stored procedure (or a SQL script) can be forced to execute
when a user logs on?
1) Is it possible to run stored procedures at specified intervals without
using the job system (through T-SQL)? I want the schedule to be
independent of the MSDB database in case of temporary failures, etc.
2) Would extended stored procedures be helpful in this scenario?
Thanks

i have a stored procedure that builds a dynamic insert statement & inserts data into a table. Now when I execute the
sp manually with a 'exec sptest parm1,parm2', it runs fine & inserts the data in the table. But when this sp is called from within a .net application,it prepares the insert statement but does not actually insert the record in the table. It comes back with a RPC: Completed so it seems like it completed but it does not insert the record in the table. Also just after the RPC:Completed, it throws an ATTENTION with nothing in the text data. I am confused on whats going on here. The definition of ATtention
in the event class implies that the query has been cancelled or it timed out. But we have no timeout on the sql server side. The application developer says there is no timeout on the application side (i dont totally believe that). so what else could
cause that Attention? There is nothing in the error log as well. Also why does the trace come back with a RPC:Completed when the stored procedure did NOT insert any data? Does the RPC:Complete only mean that the RPC completed - irrespective of success or failure? If the sp failed or had an error will it still come back with a rpc:completed?
Any thoughts are appreciated...
hi
i want to know the execution status of a stored procedure . That is i want to know whether the stored procedure was executed succesfully or not.If not i want to get the error message
I am looking for a way to count the number of times a stored procedure on the database has been executed over let's say over a period of time(month, years, etc).
Is there a system stored procedure or a system table that stores that information.
I am struggling to find some information about this topic
Thanks for the help
Hi. When SqlServer executes a procedure (any type: select, update, insert) after it´s executed can I get a default status for this executed procedure, like a return bool value from SqlServer as true for successfull and false for failed to execute?

Hello,
I have a big problem with slow execution of stored procedure in SQL Server 2005 but I really don't understand the reason. I have a database with large table (about 400 million rows) and simple stored procedure to get data from that table (one select statement to select time and value columns).
Strange thing is that if I call that stored procedure from .net application (native SqlDataProvider) it takes about 6 seconds to execute but if I call the same procedure with the same parameters from within SQL Server Management Studio it takes only 25 milliseconds to execute!
I've noticed that from .net, procedure is called with binary data and in Management Studio sql script is executed so I've copied/pasted the script from Management Studio to .net code and again the same thing happens (6 seconds from .net and 25ms from Management Studio). I traced executions with SQL Profiler and everything seems to be identical for both applications except it takes much longer time for .net application.
Both SQL Server Management Studio and .net application are on the same machine and SQL Server is on another.
This is the query that when executed in Management Studio takes 25ms:
EXEC [dbo].[GetRawData] @pcu = N'DV_ZERJ_HEV1',@tag = N'MJERENO',@from = N'20070629 07:00:00',@to = N'20070629 08:00:00'
This is the same query in .net application code that takes 6 seconds to execute:
sqlCommand = new SqlCommand("EXEC [dbo].[GetRawData] @pcu = N'DV_ZERJ_HEV1',@tag = N'MJERENO',@from = N'20070629 07:00:00',@to = N'20070629 08:00:00'",sqlConnection);
sqlReader = sqlCommand.ExecuteReader();
At first I thought that Management Studio somehow caches results but if I change parameters of stored procedure it always takes less than 30ms to execute.
I really don't understand this. Please, help!

HI,
I have an interesting situation. I have created a stored procedure which has a select union query and it accepts some parameters. When I execute this procedure it takes 8 minutes. When I copy the script in stored procedure and run it directly in Query Analyzer it takes 2 1/2 minutes?? Same numbers of rows are returned either way in the result set with about 13,000.
I cannot figure this out and it is almost the same thing except that in Query Analyzer I declare the parameters variables and its values?
Any feedback would be appreciated!
Thanks in advance...
I think not. Microsoft says it is possible: one for parallel and one for serial execution. Don't believe that's possible for a stored procedure to change execution plans on the fly. Have an on-going problem with timeout occurring with an application and narrowed the culprit to a stored procedure. I couldn't find any obvious issues database wise, no locks, etc. so I recompiled (altered) the sproc without making any changes and the issue cleared for a couple days.
It happened again to day, and so I recompiled (altered) the sproc and it went away again. No code changes to both application (so they say) and stored procedure. I ran the below code snippet to check for sprocs with multiple cached plans and the offending one came up on a short list. So, my question is, Is it one sproc per query plan or can there be more than one. I understand the connection issues.
Code:
SELECT db_name(st.dbid) DBName,
object_schema_name(st.objectid, dbid) SchemaName,
object_name(st.objectid, dbid) StoredProcedure,
MAX(cp.usecounts) Execution_count,
st.text [Plan_Text]
INTO #TMP
[Code] .....
I have a Stored Procedure (SP) that creates the data required for areport that I show on a web page. The SP does all the work and justreturns back a results set that I dump in an ASP.NET DataGrid. The SPtakes a product area and a start and end date as parameters.Here are the basics of the SP.1.Create temp table to store report results, all columns are createdthat will be needed at this point.2.Select products and general product data into the temp table.3.Create a cursor that loops through all the products in the temptable, running a more complex query with each individual product.4.The results of that query are updated on the temp table based on thecurrent product of the cursor.5.A complex "totals" query is run and the results from that areinserted into the temp table as the last 3 rows.In all we are talking about 120 rows in the temp table with 8 columnsthat are mostly numbers.I originally wrote this report SP about a month ago and it worked fine,ran in about 10 - 20 seconds based on server traffic and amount ofdata in the temp table. For the example I'm running there are the120 products.Just yesterday the (SP started timing out and when I ran the SPmanually from Query Analyzer (QA) (exec SP_NAME ... ) with the sameparameters as it was getting in the code it took 6 minutes to complete.I was floored. I immediately copied the SQL out of the SP and pastedinto another QA window, changed the variables to be hard coded valuesand ran it. It completed in 10 seconds.I'm really confused now. I ran a Profiler on the 2 when I ran themagain. The SQL code in QA executed again in ~10 seconds with 65,000reads. When the SP finished some 6 minutes later it had completed witthe right results but it needed 150,000,000 reads to do its job.How can the exact same SQL code produce such different results (time,disk reads) based on whether its in a SP or just run from QA but stillgive me the exact same output. The reports both look correct and havethe same numbers of rows.I asked my Sys Admin if he had done anything to anything and he saidno.I've been reading about recompiles and temp table indexes and allkinds of other stuff that could possibly be affecting it but havegotten nowhere.Any ideas are appreciated.
View 5 Replies View Related I am have stored procedure that accepts one parameter and returns a single value
The sp works fine.
My question is how do I set the c# webpage to return the single value.
I need a specific example of how to code.
this is how the code should work.
A blank form is loaded, when the user clicks submit I need the code to pull the Login name from the text box and check to see if it exist. I have the sp working the way I need it to. But I can figure how to pull the single value into a variable in the code behind.
I am using dataset elsewhere on the site, so I created a ds the calls the sp. Can it work this way?
thanks,

I am replicating a stored procedure execution, which builds and executes the following dynamic SQL command:
IF EXISTS (select * from MyDB..sysfiles sf (nolock) where name = 'MyDB_201201')
ALTER DATABASE [MyDB] REMOVE FILE [MyDB_201201]

I can run this SP with no errors on both the publisher and the subscriber. However, when I try to replicate the execution of this SP, I get an error in replication monitor:
ALTER DATABASE statement not allowed within multi-statement transaction. (Source: MSSQLServer, Error number: 226)
How can I change my code to workaround this? Perhaps some explicit transactions?
I have the following execution of a global temporary stored procedure on a remote SQL 2000 server:
insert into targetTable
exec remoteServer.master.dbo.sp_MSforeachdb ' ', @precommand = 'exec ##up_fetchQuery'
This is an ugly duck query but it seems to work fine. when I try to directly execute the remote stored procedure such as with
insert into query_log exec remoteServer.master.dbo.##up_fetchQuery
I get execution error
Server: Msg 2812, Level 16, State 62, Line 1
Could not find stored procedure '##up_xportQueryLog'.
Database name 'master' ignored, referencing object in tempdb.
When I try
insert into query_log exec remoteServer.tempdb.dbo.##up_fetchQuery
I get
Server: Msg 2812, Level 16, State 62, Line 1
Could not find stored procedure '##up_xportQueryLog'.
Database name 'tempdb' ignored, referencing object in tempdb.
with
insert into query_log exec remoteServer..dbo.##up_fetchQuery
or
insert into query_log exec remoteServer...##up_fetchQuery
I get
Server: Msg 2812, Level 16, State 62, Line 1
Could not find stored procedure '##up_xportQueryLog'.
I guess the remote server has trouble resolving the name of the global temp stored procedure when its reference comes in as a remote stored procedure calls. Is there any way to directly call a global temp stored procedure from a remote server or do I need to stick with this goofy-looking work-around?

Set up a trace with the events RPC:Completed, SQL:BatchCompleted, SQL:BatchStarting, and SQL:StmtCompleted.
When I issue the statement: SELECT * FROM XyzView there is nothing captured in Profiler. If I script out the view and then execute the select statement that defines the view, it does show up in Profiler.
I've tried adding a lot of the other events, i.e. SP:StmtCompleted and the various other StmtStarting events and the trace still does not capture anything.
Am I capturing the wrong events or is this known behavior? My goal is to see what the overhead is for using a view versus persisting the results of the view as a table and referencing that instead. The view in question is against static data, joins 9 tables, and is referenced a lot.
I can use the stats generated when I execute the select that defines the view but I still find this to be curious behavior so I assume I'm doing something wrong.
