Query Takes Longer To Execute The Second Time
Feb 13, 2001Has anybody come across situations where queries take longer to execute the second time? The server is a dedicated sql server box with 1gb memory.
Thanks in advance.

SQL Server 2008 :: Merge Statement Takes Several Times Longer To Execute Than Equivalent Update
Jun 20, 2013Problem 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;

Mar 1, 2005Hi we have a table with about 400000 records in it. It starting to take longer and longer to add a new record.

SP Takes Much Longer In SQL2005
Mar 28, 2008
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.
Why DELETE Takes Longer Than INSERT?
Jul 20, 2005I'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.
View 4 Replies View RelatedStored Procedure Takes Longer To Run Than The Script That's In It???
Mar 3, 2005Hi 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.

Backup Takes Longer At Month End Than Begining
Aug 1, 2007sql 2005 stnd on a server of decent spec.
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?
THanks

Query Takes More Time From User Interface Or In A Network
May 26, 2007I execute a pretty big sql query which joins multiple tables and I reviewed indexes on all these tables. I am happy with the result when I run the query using SSMS in the server locally i.e., where my SQL Server database is installed. It takes 4 seconds to get around 17000 records. If I run the same query in a network or from my desktop using SSMS i.e., i connect to the above mentioned SQL Server using SSMS, it takes more than 60 seconds. Not sure how to solve this. If someone could help me, it will be of great help.
Thanks.

SQL 2005 Express Edition SP2 - Query Takes A Long Time To Run(sometimes)
Nov 16, 2007
Hi,
I have problem with JDBC 2005 (1.1) running against SQL 2005 Express edition (SP2). Sometimes, the statement takes long time (more than 10 seconds). Sometimes, the same statement takes just a few seconds. It is very unpredictable.
The query that we have problem is most of the time is join sql statement.
Does anyone see this problem?
Thanks,
It Takes A Long Time To Insert The First Record Each Time When The Program Start
Dec 15, 2006I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.
The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?
I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.
cn.Open()
sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table
scb = New SqlCeCommandBuilder(sda)
sda.Update(dataset)
cn.Close()
I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:
1. Start the PPC Program
2. Load DB into dataset
3. Create a ONE new record in dataset
4. Fill back to DB
When I take this four steps everytime, the filling time is almost 1s or even more!
Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)
However, when I give up the dataset and using the following code:
cn.Open()
Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)
cmd.CommandType = CommandType.Text
cmd.ExecuteNonQuery()
cn.Close()
StartTime = Environment.TickCount
I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!
Problem With Getdate() In Transaction Takes The Insert Time Instead Of The Commit Time
Nov 12, 2007Hi,
We need to select rows from the database that have been recently inserted/updated. We have a main primary table (COMMIT_TEST) and a second update table (COMMIT_TEST_UPDATE). The update table contains the primary key and a LAST_UPDATE field which is a datetime (to tell us when an update occurred). Triggers on the primary table are used to populate the update table.
If we insert or update the primary table in a transaction, we would expect that the datetime of the insert/update would be at the commit, however it seems that the insert/update statement is cached and getdate() is executed at the time of the cache instead of the commit. This causes problems as we select rows based on LAST_UPDATE and a commit may occur later but the earlier insert timestamp is saved to the database and we miss that update.
We would like to know if there is anyway to tell the SQL Server to not execute the function getdate() until the commit, or any other way to get the commit to create the correct timestamp.
We are using default isolation level. We have tried using getdate(), current_timestamp and even {fn Now()} with the same results. SQL Queries that reproduce the problem are provided below:
/* Different functions to get current timestamp all have been tested to produce the same results */
/*
SELECT GETDATE()
GO
SELECT CURRENT_TIMESTAMP
GO
SELECT {fn Now()}
GO
*/
/* Use these statements to delete the tables to allow recreate of the tables */
/*
DROP TABLE COMMIT_TEST
DROP TABLE COMMIT_TEST_UPDATE
*/
/* Create a primary table and an UPDATE table to store the date/time when the primary table is modified */
CREATE TABLE dbo.COMMIT_TEST (PKEY int PRIMARY KEY, timestamp) /* ROW_VERSION rowversion */
GO
CREATE TABLE dbo.COMMIT_TEST_UPDATE (PKEY int PRIMARY KEY, LAST_UPDATE datetime, timestamp ) /* ROW_VERSION rowversion */
GO
/* Use these statements to delete the triggers to allow reinsert */
/*
drop trigger LOG_COMMIT_TEST_INSERT
drop trigger LOG_COMMIT_TEST_UPDATE
drop trigger LOG_COMMIT_TEST_DELETE
*/
/* Create insert, update and delete triggers */
create trigger LOG_COMMIT_TEST_INSERT on COMMIT_TEST for INSERT as
begin
declare @time datetime
select @time = getdate()
insert into COMMIT_TEST_UPDATE (PKEY,LAST_UPDATE)
select PKEY, getdate()
from inserted
end
GO
create trigger LOG_COMMIT_TEST_UPDATE on COMMIT_TEST for UPDATE as
begin
declare @time datetime
select @time = getdate()
update COMMIT_TEST_UPDATE
set LAST_UPDATE = getdate()
from COMMIT_TEST_UPDATE, deleted, inserted
where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY
end
GO
/* In our application deletes should never occur so we dont log when they get modified we just delete them from the UPDATE table */
create trigger LOG_COMMIT_TEST_DELETE on COMMIT_TEST for DELETE as
begin
if ( select count(*) from deleted ) > 0
begin
delete COMMIT_TEST_UPDATE
from COMMIT_TEST_UPDATE, deleted
where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY
end
end
GO
/* Delete any previous inserted record to avoid errors when inserting */
DELETE COMMIT_TEST WHERE PKEY = 1
GO
/* What is the current date/time */
SELECT GETDATE()
GO
BEGIN TRANSACTION
GO
/* Insert a record into the primary table */
INSERT COMMIT_TEST (PKEY) VALUES (1)
GO
/* Simulate additional processing within this transaction */
WAITFOR DELAY '00:00:10'
GO
/* We expect at this point that the date is written to the database (or at least we need some way for this to happen) */
COMMIT TRANSACTION
GO
/* get the current date to show us what date/time should have been committed to the database */
SELECT GETDATE()
GO
/* Select results from the table we see that the timestamp is 10 seconds older than the commit, in other words it was evaluated at */
/* the insert statement, even though the row could not be read with a SELECT as it was uncommitted */
SELECT * FROM COMMIT_TEST
GO
SELECT * FROM COMMIT_TEST_UPDATE
Any help would be appreciated, we understand we could make changes to the application/database to approximate what we need, but all the solutions have identified suffer from possible performance issues, or could still lead to missing deals (assuming the commit time is larger than some artifical time window).

Mark

Does It Take Longer To Restore The First Time?
May 16, 2007We moved a 2000 database to another platform by restoring the database. It took a lot longer than I expected. Would it take less time to restore it a second time to the same target database since the allocations are already there?
Thanks

Log Backup Takes Much Longer Than DB Backup

Inserts Taking Longer Time
May 23, 2007Hello All,
I have SQL Server 2005 installed on my machine and I am firing following query to insert 1500 records into a simple table having just on column.
Declare @i int
Set @i=0
While (@i<1500)
Begin
Insert into test2 values (@i)
Set @i=@i+1
End
Here goes the table definition,
CREATE TABLE [dbo].[test2](
[int] NULL
) ON [PRIMARY]
Now the problem with this is that on one of my server this query is taking just 500ms to run while on my production and other test server this query is taking more than 25 seconds.
Same is the problem with updates. I have checked the configurations of both the servers and found them to be the same. Also there are no indexes defined on either of the tables. I was wondering what can be the possible reason for this to happen. If any of u people has any pointers regarding this, will be really useful
Thanks in advance,
Mitesh
MS Time Series - Quick To Process The Model But Takes Very Long Time To Open Mining Model Viewer
Oct 27, 2007Hi all,
I have MS Time Seeries model using a database of over a thousand products each of which has hundreds of cases. It amazingly takes only a few minutes to finish processing the model, but when I click Mining Model Viewer to view the models, it takes many hours to show up. Once the window is open, I can choose model for different products almost instantly. Is this normal?

URGENT !!!! Transaction Log Backup Running Longer Time
Dec 26, 2002Hi Guys,
We have a database with 20 gig and with huge transactions. The transaction log backup is scheduled every one hour
from 3.00 AM to 9.00 PM.
We take a full backup in the disk at 9.00 PM and again a full backup in the tape at 2.00 AM
It works fine in the day from 6.00 AM and complete within seconds and the size is approx. 50 to 200 MB.
But the very first transaction log backup at 3.00 AM is running like 3 hrs and the size is approx. 11 gig whick is almost equivalent to the Full backup size. There are some dts packages that are running in the night and as usual reindex, intergrity checks are running and there no large user traffic during night. But I have no idea which the very first transaction log backup in the morning takes longer time and has this bug size. Is there any work around to fix this proble.
Please advise.
Thanks,
Anu

SQL SP Takes Long Time To Run From VB.NET App
Nov 22, 2007Hi all,
I have a stored procedure that is called from a VB.NET application that takes an enormously long time to execute. In the QA it only takes 10sec but in the application it takes ages. The stored procedure is as follows:
PROCEDURE NAME IS SPTOPTWENTYUSERS
SELECT TOP 20 STRUSERNAME,SUM(INTBYTESRECVD) AS INTDOWNLOAD FROM TBLISAWEBLOGS
WHERE DTELOGDATE BETWEEN @BEGINDATE AND @ENDDATE
GROUP BY STRUSERNAME
ORDER BY INTDOWNLOAD DESC
The code that runs it is as follows:
sSQLString = SPTOPTWENTYUSERS
Using cnn As New SqlConnection(GetPath)
Try
Dim cmd As New SqlCommand(sSQLString, cnn)
Dim dr As SqlDataReader
With cmd
.CommandType = CommandType.StoredProcedure
.CommandTimeout = 0
.Parameters.Add("@BEGINDATE", SqlDbType.DateTime)
.Parameters.Add("@ENDDATE", SqlDbType.DateTime)
.Parameters("@BEGINDATE").Value = dtpStartDate.Value
.Parameters("@ENDDATE").Value = dtpEndDate.Value
End With
cnn.Open()
dr = cmd.ExecuteReader
Any help on why this happens would be much appreciated.
thanks

View 2 Replies View RelatedScheduled Package Runs Longer Time Than Manually Start The Job
May 16, 2008Hi,
I have a package designed as bring data tables over to SQL Server. There are 9 data flow tasks that runs parallel, to bring 9 datatables over. In BIDS, when I execute the package, it runs like 8 minutes. Or if I start the scheduled job manually, it runs around 8 minutes too. But it runs about 30 minutes at the scheduled time at midnight.
I wonder what I can do to speed up the scheduled job.

Why It Takes Forever To Execute Stored Procedure In Reporting Services?
Sep 17, 2007I 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.

Remote Update Having A Linked Server Takes Forever To Execute
Oct 17, 2006UPDATE CD SET col1=SR.col1,col2=SR.col2,col3=SR.col3,col4=SR.col4,col5=SR.col5,col6=SR.col6,col7=SR.col7,
col8=SR.col8,col9=SR.col9,col10=SR.col10
FROM LNKSQL1.db1.DBO.Table1 CD
join Table2 USRI on USRI.col00 = CD.col00
join table3 SR on USRI.col00 = SR.col00
Here, I'm trying to tun this from an instance and do a remote update. col00 is a primary key and there is a clustered index that exists on this column. When I run this query, it does a 'select * from tabl1' on the remote server and that table has about 60 million rows. I don't understand why it would do a select *... Also, we migrated to SQL 2005 a week or so back but before that everything was running smooth. I dont have the execution plan from before but this statement was fast. Right now, I can't run this statement at all. It takes about 37 secs to do one update. But if I did the update on a local server doing remote joins here, it would work fine. When I tried to show the execution plan, it took about 10 mins to show up an estimated plan and 99% of the time was spent on Remote scan. Please let me know what I can do to improve my situation. Thank you
Send Email If Packages Executes For Longer Than A Secified Amount Of Time
Nov 15, 2007
Is there a way ( using an included SSIS task rather than coding a script task) to detect whether a package has run longer than a specified period of time?
So I can send an email to operators notifying them that a job is taking longer than usual.
Thanks
