Stored Procedure Takes Longer To Run Than The Script That's In It???
Mar 3, 2005
Hi there... I wrote a SP to check for different types of exceptions in a few database tables. When I was writing the scripts, everything seemed to execute fairly quickly and I was satisfied with the performance. When I completed the scripts and compiled them into a stored procedure and ran it (using Exec), it took a lot longer to run than I thought it would. So I went through each section of the script and ran each portion individually to see which part was taking so long.... but all the scripts ran very quickly. The individual scripts, run separately, took a combined total of 0:26 to run.... but the SP was taking 1:30 to run. (????) So then I took ALL the script contained in the SP and ran it by itself in the Query Analyzer.... it took 0:27 to run. (??????)
So basically... the script that I wrote takes 27 seconds to execute, when run by itself in the Query Analyzer... but when I take that very same script and turn it into a Store Procedure and run it, it takes a minute and a half.
Any ideas why?? I thought SP's were supposed to run faster because they're pre-compiled.
Hi we have a table with about 400000 records in it. It starting to take longer and longer to add a new record. I was thinking of creating another identical table and archiving off most of the records every month (we are now adding about about 4000 records a day) . Is this the best thing to do? I don't know a lot about sql server so any help or suggestions would be great
I have a Stored Procedure that has a query in it and it take 0 second and then a stored procedure that takes 16 seconds. From what I can tell they shoul be the same.
It doesn't recompile when i run the stored procedure, I checked that.
Hi, Is there any way to audit or record in SQL Server 2000 what queries are the ones that consume more resources in the server so I can focus and improve them?
I could use a little help here. We have a stored procedure that runs on SQL2000 and for a large dataset only takes 1-2 minutes. On SQL2005 however, it takes around 25 minutes. Any advice or insight anyone could give would be great.
Here's the stored procedure:
CREATE PROCEDURE daa_upd_relationship_balance_hist AS begin tran insert fldarts..daa_relationship_bal_hist select <-- list snipped --> from daa_relationship_bal drb, daa_user_review dur where drb.acct_no = dur.acct_no and drb.control_2 = dur.control_2 and drb.nb_gl_cost_ctr = dur.nb_gl_cost_ctr and drb.nb_dda_sav_type = dur.nb_dda_sav_type and drb.acct_no+drb.control_2+drb.nb_gl_cost_ctr+drb.nb_dda_sav_type+convert(char(10),dur.activity_date, 101) not in (select acct_no+control_2+nb_gl_cost_ctr+nb_dda_sav_type+convert(char(10), activity_date, 101) from fldarts..daa_relationship_bal_hist) if @@error = 0 commit tran else begin rollback tran print '!!!Error (daa_relationship_bal_hist) : Relationship Balance History not updated' end return GO
So we have three tables. Here's a schema for each and the indexes on them. I've omitted columns from the tables that are not utilized in this query.
daa_relationship_bal:
CREATE TABLE [daa_relationship_bal] ( [control_2] [char] (3) NOT NULL , [nb_gl_cost_ctr] [char] (7) NOT NULL , [acct_no] [char] (14) NOT NULL , [nb_dda_sav_type] [char] (3) NOT NULL )
index:
idx_upd_balance_hist nonclustered located on PRIMARY acct_no, control_2, nb_gl_cost_ctr, nb_dda_sav_type
daa_user_review:
CREATE TABLE [daa_user_review] ( [control_2] [char] (3) NOT NULL , [nb_gl_cost_ctr] [char] (7) NOT NULL , [acct_no] [char] (14) NOT NULL , [nb_dda_sav_type] [char] (1) NOT NULL , [activity_date] [datetime] NULL )
index:
PK_daa_user_review_1__37 nonclustered, unique, primary key located on INDEXES control_2, nb_gl_cost_ctr, acct_no, nb_dda_sav_type
daa_relationship_bal_hist:
CREATE TABLE [daa_relationship_bal_hist] ( [control_2] [char] (3) NOT NULL , [nb_gl_cost_ctr] [char] (7) NOT NULL , [acct_no] [char] (14) NOT NULL , [nb_dda_sav_type] [char] (3) NOT NULL , [activity_date] [datetime] NOT NULL )
index:
PK_daa_rel_bal_hist_1__37 nonclustered, unique, primary key located on PRIMARY control_2, nb_gl_cost_ctr, acct_no, nb_dda_sav_type, activity_date
Any help on this would be great. If more information is needed, please let me know.
I'm running an ISP database in SQL 6.5 which has a table 'calls'. When thenew month starts I create a new table with the same fields and move the dataof previous month into that table and delete it from calls. So 'calls' holdsthe data of only the current month. for example at the start of november2003 I ran the queriesCreate Table Oct2003Calls {................................}/* Now insert data of october into new table */INSERT Oct2003CallsSELECT *FROM callsWHERE calldate < '11/1/03'/* Finaly delete october data from calls table */DELETE FROM callsWHERE calldate < '11/1/03'The problem is that while the insert query takes about 2 minutes to executethe delete queries takes over 10 minutes to affect the same no. of rows. Whyis that?This causes problems because user authentication stops when this query isrunning which means users cant connect to the internet.
dbase in question is only about 5GB on a 450GB partition.
at the begining of the month I run:
BACKUP LOG [objectstore] TO DISK ='D:BackupsProdackup_objectstore.BAK' WITH NOFORMAT , INIT , NAME = N'objectstore backup'
and then every 10 minutes (within working hours) for the rest of the month I run:
BACKUP LOG [objectstore] TO DISK ='D:BackupsProdackup_objectstore.BAK' WITH NOFORMAT , NOINIT , NAME = N'objectstore backup'.
The amount of data that gets backed up is the same through out the month and the loading on the server as a whole also stays constant throughout the month - NOTHING increases throughout the month that would affect this server in any way, yet at the begining of the month the backup takes 10 seconds, and at the end, it gets up to 5-6 minutes.
why?

On SQL 2012 (64bit) I have a CLR stored procedure that calls another, T-SQL stored procedure.
The CLR procedure passes a sizeable amount of data via a user defined table type resp.table values parameter. It passes about 12,000 rows with 3 columns each.
For some reason the call of the procedure is verz very slow. I mean just the call, not the procedure.
I changed the procdure to do nothing (return 1 in first line).
So with all parameters set from
command.ExecuteNonQuery()to create proc usp_Proc1 @myTable myTable read only begin return 1 end
it takes 8 seconds.I measured all other steps (creating the data table in CLR, creating the SQL Param, adding it to the command, executing the stored procedure) and all of them work fine and very fast.
When I trace the procedure call in SQL Profiler I get a line like this for each line of the data table (12,000)
SP:StmtCompleted -- Encrypted Text.
As I said, not the procedure or the creation of the data table takes so long, really only the passing of the data table to the procedure.
We are importing xer formats through the wizard to sqlserver database and It takes upto 35-45 mins for each import (single project), any option to reduce the time.Is they any other import options - which can give us faster results.
I have a process that keeps check on the row counts of about 100 stored procedures. The input parameters and "certified" row counts for all of the stored procedures are stored in a database. The process runs every day and executes all of the stored procedures using the parameters from the database with syntax below. The row count returned is compared against the known "certified" row count. If the counts are different, we receive an email alerting us that something has changed with the data or the sp query.
(This code is dynamically generated for all 100 + stored procedures)
SELECT COUNT(*) FROM OPENQUERY(SQLSERVER,'EXEC 'usp_HR_My_Stored_Procedure @inputparam1="12345",@inputparam2="12345"')
This worked well until I upgraded from SQL Server 2008 R2 to SQL Server 2014. Evidently Microsoft fixed this for me. The error below is now received anytime we attempt to execute a stored procedure with dynamic SQL through OPENQUERY.
The metadata could not be determined because statement 'EXEC (@sql_str)' in procedure 'usp_HR_My_Stored_Procedure ' contains dynamic SQL. Consider using the WITH RESULT SETS clause to explicitly describe the result set.
The stored procedures that are monitored change frequently, so it isn't reasonable to create tables with fixed column structures for all for all of the stored procs.
Problem Summary: Merge Statement takes several times longer to execute than equivalent Update, Insert and Delete as separate statements. Why?
I have a relatively large table (about 35,000,000 records, approximately 13 GB uncompressed and 4 GB with page compression - including indexes). A MERGE statement pretty consistently takes two or three minutes to perform an update, insert and delete. At one extreme, updating 82 (yes 82) records took 1 minute, 45 seconds. At the other extreme, updating 100,000 records took about five minutes.When I changed the MERGE to the equivalent separate UPDATE, INSERT & DELETE statements (embedded in an explicit transaction) the entire update took only 17 seconds. The query plans for the separate UPDATE, INSERT & DELETE statements look very similar to the query plan for the combined MERGE. However, all the row count estimates for the MERGE statement are way off.
Obviously, I am going to use the separate UPDATE, INSERT & DELETE statements. The actual query plans for the four statements ( combined MERGE and the separate UPDATE, INSERT & DELETE ) are attached. SQL Code to create the source and target tables and the actual queries themselves are below. I've also included the statistics created by my test run. Nothing else was running on the server when I ran the test.
Server Configuration:
SQL Server 2008 R2 SP1, Enterprise Edition 3 x Quad-Core Xeon Processor Max Degree of Parallelism = 8 148 GB RAM
SQL Code:
Target Table: USE TPS; IF OBJECT_ID('dbo.ParticipantResponse') IS NOT NULL DROP TABLE dbo.ParticipantResponse;
I have a sp that was taking very little time (about 34 sec). But suddenly is stacked. It is running and running and running but not LOCKED neither SUSPENDED. It is always RUNNABLE. I have made Index and statistics optimization but nothing. I looked into execution plan but everything seems ok. All the time is in 3 indexes that are Index Seek and not Table Scan!!! So why is stacked... I do not know how much time it takes because I have to stop it. (SQL SERVER 2008 R2, the database was migrated from SQL SERVER 2000)
I need to call a SQL Server stored procedure, which takes over five hours to run, from an asp.NET web page. This procedure then calls a DTS package which is what takes 5+ hours to run. I need the user to be able to click on the 'run' button and have the page kick off the stored procedure (or the DTS Package if that will work instead) and display a message saying the load has begun and to check a 'status' link.
Right now I get a page timeout because it's waiting for results.
Any help would be greatly appreciated! Thanks, cat72
The query below runs in sub second time if I don't call it as a stored procedure. I have looked at the execution plan for both the query and the query as a stored procedure and they are the same. When I put the query into a stored procedure it takes over 2 minutes to run. All feedback (even the ugly stuff) is more than welcome. I want to master this issue and forever put it behind me.

I used a stored procedure in my report. If I run the sp in Management Studio (on my pc, database is on a sql server) it takes only several minutes; but from reporting services (also on pc) I put it in the data tab and execute it, it takes forever, actually never finish. I want to know why it's taking so long to execute it from reporting services while it returns data instantly from Mgt Studio. There is cursor in the sp. I don't know whether this is the culprit. Anyone knows why? Thanks!
Below is the sp. --------------------------------------------------------------------

Hi,I have stored procedure (MS SQL Server 2000) which operateson around 600 000 rows (SELECT, UPDATE, INSERT)and executes in 5 minutes,when I put it in SQL transaction it slows down to more than 5 hours (!!)I have to admit that it is not problem with data locks (beside thatprocedurenothing else is executed on db),It is not also problem with that exact procedure, other proceduresalso slow down heavily when wrapped by SQL transactionvery very seldom stored procedure within transaction executescomparably long that its copy without transactionI guess it could be MS SQL Server 2000 configuration/tuning problem.Any ideas ?Chris
hi, this stored procedure below takes 25 mins to execute. is this normal? and is there a faster way to do this? its not like i have millions of records, i only have about 170.

I have been googling all day and not found a reasonable solution to my problem.
Here is what I am trying to do. The T-SQL code is included at the bottom of this message.
- The user can specify columns that are stored in a CVColumn table (the data for which comes from an external source). For example, we may provide LastName and FirstName columns and the user could add ShoeSize and FavoriteColor.
- When we get the data from the other source, we create it as a dataset in the *code* with each user-defined field as a column of the table and each person as a row in the table. This is used *everywhere* including binding to grids, etc... So the dataset may look like this: PersonID LastName FirstName ShoeSize FavoriteColor
- The dba has required that the data be stored in a normalized fashion. Since we don't know what the columns are - the data is stored in the *table* as: PersonID ColumnName ColumnValue
- When the user gets the data from the external source the first time, the code loops through every person row and every column of the row to insert fields into the table using an Insert stored proc. This performs reasonable well.
- When the code retrieves the data from the database, it needs to reformat the data into one row per person, one column per field so that all of the other code can do the binding, etc.
- So I created a temp table with the appropriate rows and columns and then updated that table with the appropriate data. *This* is the stored proc that has been running now for almost an hour.
- There *must* be a way to do this that performs better?
Here is my T-SQL:

Any ideas or othre suggestions would be much appreciated!
(BTW - up until today the data from the code-based dataset was stored as XML and then read back as XML. However, we found with 80,000+ people that it took 5 minutes to read the XML. But that is faster than this stored proc!<G>)
I am having to debug a procedure that is called by a control in javascript that I do not have any control over accept for setting the procedure name to call.
I matched my parameters to my procedure to what I define as the parameters list, but somehow I keep getting a too many parameters specified.
If I had control over it in C# it would be easy to select which params are actually being sent, but I would like to give a procedure name to call and I can log the parameters sent somewhere.how to do.
Why does it take longer and longer for the same code to run very simply I have 8,0000,000 records I want to delete from a table . I have tried a few options
Option 1 a while loop which deletes 10,000 rows per loop starting from the earliest until it hits the cut of number I have set. THIS TOOK 5 HOURS
Option 2 created an SP which found the oldest 100,000 records then deleted them. If I run this SP manually it takes 30 €“ 60 secs. Which I thought was much better than above. So I put this SP in a while loop to run 80 odd times thinking the time it would take would be 80 mins a huge improvement.
But every time this SP is called it takes longer and longer (36,30,32,39,37,37,123,163,155,182€¦and so on(In seconds)).
All the sp is doing is as follows(8860000 is just to insure I don€™t delete to much). this sp is then called from in a while loop.
set @recnumber = (select top 1 recnumber from (select top 100000 recnumber from TabletodeleteFROM where recnumber < 8860000 order by recnumber asc ) TabletodeleteFROM order recnumber desc)
delete TabletodeleteFROM where recnumber < @recnumber
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?

More Information for you to know: I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly. I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.
I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete] @QQ_YYYY char(7), @YYYYQQ char(8) AS begin SET NOCOUNT ON; select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],
I have a sub that passes values from my form to my stored procedure. The stored procedure passes back an @@IDENTITY but I'm not sure how to grab that in my asp page and then pass that to my next called procedure from my aspx page. Here's where I'm stuck: Public Sub InsertOrder() Conn.Open() cmd = New SqlCommand("Add_NewOrder", Conn) cmd.CommandType = CommandType.StoredProcedure ' pass customer info to stored proc cmd.Parameters.Add("@FirstName", txtFName.Text) cmd.Parameters.Add("@LastName", txtLName.Text) cmd.Parameters.Add("@AddressLine1", txtStreet.Text) cmd.Parameters.Add("@CityID", dropdown_city.SelectedValue) cmd.Parameters.Add("@Zip", intZip.Text) cmd.Parameters.Add("@EmailPrefix", txtEmailPre.Text) cmd.Parameters.Add("@EmailSuffix", txtEmailSuf.Text) cmd.Parameters.Add("@PhoneAreaCode", txtPhoneArea.Text) cmd.Parameters.Add("@PhonePrefix", txtPhonePre.Text) cmd.Parameters.Add("@PhoneSuffix", txtPhoneSuf.Text) ' pass order info to stored proc cmd.Parameters.Add("@NumberOfPeopleID", dropdown_people.SelectedValue) cmd.Parameters.Add("@BeanOptionID", dropdown_beans.SelectedValue) cmd.Parameters.Add("@TortillaOptionID", dropdown_tortilla.SelectedValue) 'Session.Add("FirstName", txtFName.Text) cmd.ExecuteNonQuery() cmd = New SqlCommand("Add_EntreeItems", Conn) cmd.CommandType = CommandType.StoredProcedure cmd.Parameters.Add("@CateringOrderID", get identity from previous stored proc) <------------------------- Dim li As ListItem Dim p As SqlParameter = cmd.Parameters.Add("@EntreeID", Data.SqlDbType.VarChar) For Each li In chbxl_entrees.Items If li.Selected Then p.Value = li.Value cmd.ExecuteNonQuery() End If Next Conn.Close()I want to somehow grab the @CateringOrderID that was created as an end product of my first called stored procedure (Add_NewOrder) and pass that to my second stored procedure (Add_EntreeItems)
I have a stored procedure and in that I will be calling a stored procedure. Now, based on the parameter value I will get stored procedure name to be executed. how to execute dynamic sp in a stored rocedure
at present it is like EXECUTE usp_print_list_full @ID, @TNumber, @ErrMsg OUTPUT
I want to do like EXECUTE @SpName @ID, @TNumber, @ErrMsg OUTPUT
