Ad Hoc Query Vs Stored Procedure Performance Vs DTS Execution Of Stored Procedure
Jan 23, 2008
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

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] .....

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?

Hi group,I have a select statement that if run against a 1 million recorddatabase directly in query analyzer takes less than 1 second.However, if I execute the select statement in a stored procedureinstead, calling the stored proc from query analyzer, then it takes12-17 seconds.Here is what I execute in Query Analyzer when bypassing the storedprocedure:USE VerizonGODECLARE @phonenumber varchar(15)SELECT @phonenumber = '6317898493'SELECT Source_Identifier,BADD_Sequence_Number,Record_Type,BAID ,Social_Security_Number ,Billing_Name,Billing_Address_1,Billing_Address_2,Billing_Address_3,Billing_Address_4,Service_Connection_Date,Disconnect_Date,Date_Final_Bill,Behavior_Score,Account_Group,Diconnect_Reason,Treatment_History,Perm_Temp,Balance_Due,Regulated_Balance_Due,Toll_Balance_Due,Deregulated_Balance_Due,Directory_Balance_Due,Other_Category_BalanceFROM BadDebtWHERE (Telephone_Number = @phonenumber) OR (Telephone_Number_Redef =@phonenumber)order by Service_Connection_Date descRETURNGOHere is what I execute in Query Analyzer when calling the storedprocedure:DECLARE @phonenumber varchar(15)SELECT @phonenumber = '6317898493'EXEC Verizon.dbo.baddebt_phonelookup @phonenumberHere is the script that created the stored procedure itself:CREATE PROCEDURE dbo.baddebt_phonelookup @phonenumber varchar(15)ASSELECT Source_Identifier,BADD_Sequence_Number,Record_Type,BAID ,Social_Security_Number ,Billing_Name,Billing_Address_1,Billing_Address_2,Billing_Address_3,Billing_Address_4,Service_Connection_Date,Disconnect_Date,Date_Final_Bill,Behavior_Score,Account_Group,Diconnect_Reason,Treatment_History,Perm_Temp,Balance_Due,Regulated_Balance_Due,Toll_Balance_Due,Deregulated_Balance_Due,Directory_Balance_Due,Other_Category_BalanceFROM BadDebtWHERE (Telephone_Number = @phonenumber) OR (Telephone_Number_Redef =@phonenumber)order by Service_Connection_Date descRETURNGOUsing SQL Profiler, I also have the execution trees for each of thesetwo different ways of running the same query.Here is the Execution tree when running the whole query in theanalyzer, bypassing the stored procedure:--------------------------------------Sort(ORDER BY:([BadDebt].[Service_Connection_Date] DESC))|--Bookmark Lookup(BOOKMARK:([Bmk1000]),OBJECT:([Verizon].[dbo].[BadDebt]))|--Sort(DISTINCT ORDER BY:([Bmk1000] ASC))|--Concatenation|--IndexSeek(OBJECT:([Verizon].[dbo].[BadDebt].[Telephone_Index]),SEEK:([BadDebt].[Telephone_Number]=[@phonenumber]) ORDERED FORWARD)|--IndexSeek(OBJECT:([Verizon].[dbo].[BadDebt].[Telephone_Redef_Index]),SEEK:([BadDebt].[Telephone_Number_Redef]=[@phonenumber]) ORDEREDFORWARD)--------------------------------------Finally, here is the execution tree when calling the stored procedure:--------------------------------------Sort(ORDER BY:([BadDebt].[Service_Connection_Date] DESC))|--Filter(WHERE:([BadDebt].[Telephone_Number]=[@phonenumber] OR[BadDebt].[Telephone_Number_Redef]=[@phonenumber]))|--Compute Scalar(DEFINE:([BadDebt].[Telephone_Number_Redef]=substring(Convert([BadDebt].[Telephone_Number]),1, 10)))|--Table Scan(OBJECT:([Verizon].[dbo].[BadDebt]))--------------------------------------Thanks for any help on my path to optimizing this query for ourproduction environment.Regards,Warren WrightScorex Development Team

Executing the stored procedure took 45 seconds. But copying the code to a query window and setting up the variables (instead of parameters), it took 7 seconds.
In the query window, most of the processing cost (86%) is right up front in a "Distinct Sort." But in exec stored procedure, the cost for this step is 11% and the significant costs are in later "Table Scans."
I don't know why SQL Server would choose different execution plans when the code is identical in each.
Any quick insights?
Many thanks.

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

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...

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!

For some reason, I run a stored procedure in Query Analyzer and it works fine. When I run the very same procedure in MS access by clicking on its link I have to run it twice. The first run gives me the message that the stored procedure ran correctly but returned no records. The second run gives me the correct number of records but I have to run it twice. I am running month-to-month data. The first run is Jan thru March. Jan and Feb have no records so I run three months on the first set. The ensuing runs are individual months from April onward. The output is correct but any ideas on why I have to do it twice in Access? I am a bit new to stored procedures but my supervisor assures me that it should be exactly the same.

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.

But this procedure table about 3 min to generate result set. I am not using any temp table. I am using table variables.
My procedure do not recompile.
My rocedure have some insert into ... Exec statements also..
My question is Will performance increase if i split the stored procedure into 2 or 3 or 4 parts?

Hello,
Given that a stored procedure and T-SQL code in query analyzer are exactly the same, why would the stored procedure run much slower?
When I mean much slower I mean 3 sec for the code in query analyzer as opposed to 2:33 sec for the stored procedure.
Exact same code!
Profiler also gives more reads and writes for stored procedure, and a lot of BatchStarted and BatchCompleted directives between the 'start' and 'end' of the stored procedure.
Any help is greatly appreciated.

I have another stored procedure that's executed from this one that I will also parameter-ize.
