Retrieving Data From Table With 7 Million Entries Takes Time
Jul 25, 2007
Can anyone help me on this...
when i select data from table using select statement it takes huge amount of time....The table contains 7 million entries and when i select by mentioning a criteria it takes around 45 secs..The system has 4GB RAM and Dual Processing CPU. The select statement does not contain any grouping and all..
Will it take this much time to retrieve data.?.
The table does include an indexed field,
So can anyone help me on the different things i can do to make the retrieval faster?

I have a row that is being used log track plays on our website.
Here's the table:
CREATE TABLE [dbo].[Music_BandTrackPlays](
[ListenDate] [datetime] NOT NULL DEFAULT (getdate()),
[TrackId] [int] NOT NULL,
[IPAddress] [varchar](20)
) ON [PRIMARY]
There's a CLUSTERED INDEX on ListenDate ASC and a NON CLUSTERED INDEX on the TrackId.
I have a TRIGGER on the Music_BandTrackPlays table that looks like the following:
CREATE TRIGGER [trig_Increment_Music_BandTrackPlays_PlayCount]
ON [dbo].[Music_BandTrackPlays] AFTER INSERT
AS
UPDATE
Music_BandTracks
SET
Music_BandTracks.PlayCount = Music_BandTracks.PlayCount + TP.PlayCount
FROM
(SELECT TrackId, COUNT(*) AS PlayCount
FROM inserted
GROUP BY TrackId) AS TP
WHERE
Music_BandTracks.TrackId = TP.TrackId
When a simple INSERT statement is done on the Music_BandTrackPlays table, it can take quite a long time. When I remove the TRIGGER the INSERTs are immediate. The Execution plan for the TRIGGER shows that a 'Inserted Scan' is taking up most of the resources.
How exactly is the pseudo 'inserted' table formed?
For now, I think the easiest thing to do is update my logging page so it performs 2 queries. One to UPDATE the Music_BandTracks table and increment the counter, and perform the INSERT into the Music_BandTrackPlays table seperately.
I'm ok with that solution but I would really like to understand why the TRIGGER is taking so long. The 'inserted' pseudo table will be 1 row 99% of the time. Does SQL Server perform a table scan on all 20 million rows in order to determine what's new and put it in the inserted pseudo table?
Thanks!

The following T-SQL code is run in a vb.net (2003) module.
I am acquiring data from an OPC server into an array of data type object. It is necessary to declare the array as an object for the OPC server to return data. The OPC returns the data in 15 mS.
I now need to save this data to a table in SQL 2005 running on a 2003 server.
The table for saving the data has already been created and saving the data is actually an 'update ... set ... where' statement.
The statement is
For i as short = 1 to itemCount
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = " & itemValue(i) & " where TagName =' " & tagName(i)
sql_command.executeNonQuery
Next
The TagValue field datatype is decimal(18,6)
The itemValue(i) datatype is object / variant. The itemValue array contains 95% values of type Single and the rest are Integers.
The TagName datatype is varchar(50)
The tagName(i) datatype is string
When I run the loop (255 iterations) with the above query it takes 1500 mS.
If I force a conversion by changing the query to
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = Convert(decimal, " & itemValue(i) & ") where TagName =' " & tagName(i)
it takes 900 mS to execute for 255 iterations.
I tried one more variation
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = Convert(decimal(18,6), " & itemValue(i) & ") where TagName =' " & tagName(i)
which takes 1200 mS to execute for 255 iterations.
If I use the following code
dim tempValue as decimal = 123456789012.123456D
sql_command = "Update [IO Log].[dbo].[IO Log] Set TagValue = " & tempValue & " where TagName =' " & tagName(i)
it excutes in under 100 mS for 255 iterations.
There seems to be a problem during implicit / explicit conversion of type object/variant to decimal.
I need to save the data received from the OPC (255 tags) in under 150 mS.
Could somebody help?

Hi,
The scenario is the data comes from various sources and its staged into staging database. From this staging database it goes into data warehouse database. Everyday this staging database is truncated and repopulated from various sources.
I've a dimension table called DimCustomers which consists of around 300,000 rows and has lots of different types of SCD columns. It takes around 4-5 hours to load data from staging to this dimension table. Currently I'm using a For Loop container which uses a store proc to extract 15000 rows each time and populate my dimension tables. First couple of loops it goes off quickly but as and when the number reaches half of the count it slows down and hence it takes around 4-5 hours to load data.
What would be the best approach to populate this kind of dimension table.
Thanks

Dear all,
i need to design a database table which will store supplier's demand information. 1 supplier will probably have 10000 records and there are posibility that there are 10,000 suppliers. So, in total, the number of records will be 10000 * 10000 = XXXXA LOT XXXX which will be very large number of record to be inserted into a table. So, how can i design an table and structure to cater this scenario? Thanks.
Hope to hear from you..

I have been tasked with writing an update query to update a table with more than 150 million rows of data. Here are the table structures:
Source Tables :
OC
CREATE TABLE [dbo].[OC](
[OC] [nvarchar](255) NULL,
[DATE DEBUT] [date] NULL,
[DATE FIN] [date] NULL,
[Code Article] [nvarchar](255) NULL,
[INSERTION] [nvarchar](255) NULL,
[Code] ....
The update requirement is as follows:
DECLARE @Counter INT=0 --This causes the @@rowcount to be > 0
while @@rowcount>0
BEGIN
  SET rowcount 10000
  update r
  set Comp=t.Comp
[Code] ....
The update took more than 48h and didn't terminate , how to accelerate it ?

I 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!!!

Hi,
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 don€™t 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).
Regards,
Mark

I have nine type of buttons,

PlacAmtBTM and so on, I also have a SQL setver view V_Payment_Amount_List from here i need to display the data on the button
this is the select value to display when i choose the agency list and the amount corresponding to that agency_ID is displayed here the agency_ID is fetched from the SQL CONDITION
THIS IS WHERE I GET FETCH AGENCY DATA WHEN SELECTED i.e SQL CONDITIONprotected void CollectAgencyInformation()

}
SelectedAgency = SQLCONDITION;
ValueSelected.CONDITION = SelectedAgency;
???? this is where i use to get count where in other buttons and are displayed.... but i changed the query to display only the Payment_Amount_Budgeted respective to the agency selected. from the viewRUN_SQLCONDITION = "SELECT Payment_Amount_Budgeted FROM dbo.V_Payment_Amount_List " + SQLCONDITION;
try
{
CollectionCount = ConnectionFinanceDB.CollectedFinaceDataCount(RUN_SQLCONDITION);
EnrollAmtBTM.Text = CollectionCount.ToString();
}
catch
{
}////this is my CollectedFinaceDataCount-- where fuction counts the records in the above select statement if i use for eg.
"SELECT Count(Placement_Retention_ID) FROM dbo.V_Retention_6_Month_Finance_Payment_List"
here is the functionpublic int CollectedFinaceDataCount(String SQLStatement)
{int DataCollection;
DataCollection = 0;
try

DisconnectToDatabase();
}catch (Exception ex)
{Console.WriteLine("Exception Occurred :{0},{1}",
ex.Message, ex.StackTrace.ToString());

So here mu requirement request is to display only the value fronm the view i have against the agency selected
Please help ASAP

this is a simple problem but it's just driving me mad as it's not reading from my dB. basically, I've have reviews stored in my dB and want to display them in a textbox by clicking on a button called btnReviews. I think the problem might be that there is too much text stored per row of the table (as it is a review), but I have the datatype set as text in sql. here's the simple un-errorred code I have behind the button. any ideas where I went wrong. i've a feeling it's something small but it's just taken too long to figure out.protected void btnReviews_Click(object sender, EventArgs e) { String strConn = ConfigurationManager.ConnectionStrings["conLocalDatabase"].ConnectionString; SqlConnection dbConnection = new SqlConnection(strConn); SqlCommand dbCommand = new SqlCommand("Select [ReviewC] From [Review])", dbConnection); dbCommand.Parameters.AddWithValue("Review", txtReviewView.Text); try { dbConnection.Open(); dbCommand.ExecuteNonQuery(); } catch (SqlException ex) { Console.WriteLine(ex.ToString()); } finally { if (dbConnection != null) { dbConnection.Close(); } } }

I would like to retrieve a hierarchical list of Product Categories from a single table where the primary key is a ProductCategoryId (int) and there is an index on a ParentProductCategoryId (int) field. In other words, I have a self-referencing table. Categories at the top level of the hierarchy have a ParentProductCategoryId of zero (0). I would like to display the list in a TreeView or similar hierarchical data display control.Is there a way to retrieve the rows in hierarchical order, sorted by CategoryName within level?

Hi 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

Hi,
I have SQL Server 2005 Standard edition with SP1. Whenever I start the Management Studio, it takes for ever to come up. It will take atleast 30 Sec to 1 min every time I start SQL Server. Is this some thing we have to live with in SQL Server 2005 or do I need to tweak any thing? Pls let me know.
One more thing, in the SQL Server logs I see the following message every day -> Source - spid36s, Message - Starting up database 'dbname'. Why do I get this message?
Thanks

Hi,
It seems inserting records takes a relatively long time. My guess is it needs time to allocate disk space for the extra space needed. Assuming this is true, are there any DB settings that allow auto space allocation in bigger chunk? I am looking for something like "DB growth factor" or " Table growth factor"
Thanks for any info.

Dear friends,
Our package which at the time of normal execution takes 2-2:30 mins for fetching data on VPN with some select queries. But some times its job runs for hours and hours. What could be the exact reason behind it? I guess its queries are stuch somewhere, but not when we run from the BIDS or run the job manually.
Please help. Thanks.
