Slow Execution Of Stored Procedure
Jun 29, 2007
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!

Dear friends,I have a problem with a simple select statement and I don't know why it is happening.I have 2 tables, Fees and FeesDataRoles. Fees presents all the fees and FeesDataRole is a middle table between Fees and Roles table. So each fee can have multiple Roles and a Role can have many Fees.Now I have a select statement:Select *From Fees Inner Join FeesDataRoles ON Fees.FeeID = FeesDataRoles.FeeIDWhere (FeesDataRoles.DataRoleID = @DataRoleID) AND (FeesDataRoles.RecordStatus = 1 ) AND (FeesDataRoles.ValidFrom >= getdate() ) AND ( FeesDataRoles.ValidTo <= getdate() OR FeesDataRoles.ValidTo is null)Now it shouldn't take that long to execute this procedure but surprisingly sometimes when I insert a value to the table and then execute this store procedure it does now show the data just added. Very strange.....!!!!I ran the procedure 5 times after inserting an item and nearly 1 out of 5 does not return the right result righ. ( It does not include the recently inserted rows)Anyone have any idea....?I used Tuning Advisor, no sugestion. I change the clustered index in FeesDataRoles from FeesDataRoleID(the primary key of the table) to DataRoleID to increase the performance, still it happens sometimes.Is my Where clause so costly that cause this problem.Please help. I really appreciate your help.Regards,Mehdi

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

When the same code is executed in query analyzer it takes 2s instead of 20s when executing the sp. Any idea?

When i execute a stored procedure it generally takes about half a second to run but sometimes it takes 20 to 30 seconds. I am the only one using the server so I know it is not due to other traffic. I have looked at Profiler and nothing looks out of the ordinary. Another observation is that the slow ones are always near eachother. I will have about 10 fast executions and then 3 slow ones and then back to fast ones. Has anyone seen anything like this before?

We have a stored procedure which is running fine on a SQL server 2000 from Query Analyzer. However, when we try to execute the same stored procedure from ADO.NET in an executable, the execution is hung or takes extremely long. Does anyone have any ideas or suggestions about how it could happen and how to fix. thanks

Hi all,
I have a webpage with a Datagrid that populates using a table adapter from a Stored procedure that exists in my SQL Database...If I run the Stored procedure in SQL Directly then it takes 20 Secs to return all records...If I run the webpage then it takes just over 20 Secs..
Great you say..But If I have the sorting option set in ASP.net and I click on a column to sort then off the page goes for another 20 secs to sort the data..
Is there a better way to do what I am doing here that will speed up the page load..
Ie..the data is returned once and then sorted...
Is it Better / Quicker for me to create a table using the stored procedure and link to this from the website..Updating the table every couple of minutes ?
Any advice please ?
Ray..

I have developed a stored procedure that filters a view that is a union of several different tables. This provides status information for items across our warehouse management system. This system seems to work very well and normally processes results very quickly (< 3 seconds). However, occasionally (every few days) we begin to see timeouts on the query after 3 minutes of processing. I can watch this process in SQL Profiler and see that the query is timing out after 180 seconds, which is the timeout we have for the query within the DAL. When I copy the line from the SQL Profiler and execute it directly in SSMS, the query executes in less than 2 seconds. I first thought that somehow this had to do with execution plans, but when I try to reload the page again, which executes the query, it still times out. I did add a OPTION(KEEPFIXED PLAN) to the sproc, and that seemed to speed things up for the time, but I am not sure if this is even the problem and what the optimal solution would be. Any thoughts spring to mind?
Thanks, Steve

Hi,Plz, I need some info (SQL2000) :)A stored procedure is like this:"Select table1.id, table1.txt, (select table2.nr from table2 wheretable2.fk_table1=table1.id) as nr where table1.id<>10"The essence here is that "select table2.nr from table2 wheretable2.fk_table1=table1.id" returns either the integer in table2.nr, or NULLif there isnt a match. The whole sentence runs EXTREMELY slow...3-4 sec.What is wrong?"select table2.nr from table2 where table2.fk_table1=table1.id" runs quicklyoutside the stored procedure. The original sentence without the "nr" (Selecttable1.id, table1.txt where table1.id<>10) runs quickly too...But together it slows down dramatically..why? I should mention that thesub-query could return NULL if theres no match in table2...But i cant seewhy that should slow things down (remember - it runs fine outside the SP)?Thx,PipHans---Outgoing mail is certified Virus Free.Checked by AVG anti-virus system (http://www.grisoft.com).Version: 6.0.518 / Virus Database: 316 - Release Date: 11-09-2003

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. 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?

@dhb_service = 'canterbury' ,@dhbname = 'south canterbury'
SQL does not give me any results, only empty table gets displayed. I have checked the combination.. This combination does exist in my table

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.

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

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.

Is 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?
