Insertion And Updates On 20.000.000 Tuples Table.
Jun 23, 2006
Hi,
I have a table with 20.000.000 of tuples.
I have been monitoring the performance of the insertion and updates,
but not convince me at all.
The table have 30 columns, what and 12 of it, are calcultated column.
The test that i do was this:
1 Insertion with all the columns and calculing the calcultated columns
in the insertion sentence.
1 insertion and all the columns calculated in @vars..
1 insertion with the basic fields, and 10 updates.
And the result was that the last test was the most performant.
What is your opinion?

Hi...
I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...
this is my sproc...
ALTER PROCEDURE [dbo].[usp_Import_Plan]
@ClientId int,
@UserId int = NULL,
@HistoryId int,
@ShowStatus bit = 0-- Indicates whether status messages should be returned during the import.
AS
SET NOCOUNT ON
DECLARE
@Count int,
@Sproc varchar(50),
@Status varchar(200),
@TotalCount int
SET @Sproc = OBJECT_NAME(@@ProcId)
SET @Status = 'Updating plan information in Plan table.'
UPDATE
Statements..Plan
SET
PlanName = PlanName1,
Description = PlanName2
FROM
Statements..Plan cp
JOIN (
SELECT DISTINCT
PlanId,
PlanName1,
PlanName2
FROM
Census
) c
ON cp.CPlanId = c.PlanId
WHERE
cp.ClientId = @ClientId
AND
(
IsNull(cp.PlanName,'') <> IsNull(c.PlanName1,'')
OR
IsNull(cp.Description,'') <> IsNull(c.PlanName2,'')
)
SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Updated ' + Cast(@Count AS varchar(10)) + ' record(s) in ClientPlan.'
END
ELSE
BEGIN
SET @Status = 'No records were updated in Plan.'
END
SET @Status = 'Adding plan information to Plan table.'
INSERT INTO Statements..Plan (
ClientId,
ClientPlanId,
UserId,
PlanName,
Description
)
SELECT DISTINCT
@ClientId,
CPlanId,
@UserId,
PlanName1,
PlanName2
FROM
Census
WHERE
PlanId NOT IN (
SELECT DISTINCT
CPlanId
FROM
Statements..Plan
WHERE
ClientId = @ClientId
AND
ClientPlanId IS NOT NULL
)
SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Added ' + Cast(@Count AS varchar(10)) + ' record(s) to Plan.'
END
ELSE
BEGIN
SET @Status = 'No information was added Plan.'
END
SET NOCOUNT OFF
So how do i do multiple inserts and updates using this stored procedure...
Regards
Karen

this context. Valid expressions are constants, constant expressions, and (in
some contexts) variables. Column names are not permitted.I wrote the code like following protected void Button1_Click(object sender, EventArgs e) { string street = txtStreetNo.Text; string city = txtCity.Text; string pincode = txtPincode.Text; string com = street + city+pincode; conn.Open(); SqlDataAdapter daInsert = new SqlDataAdapter("insert into Address values(" + com.ToString() + ")", conn); daInsert.SelectCommand.ExecuteNonQuery();--->here its giving the exception conn.Close(); Response.Write("the values are inserted"); }Please any one tell me am I did the code write or not if its not please give any suggetionsthanksGeeta

hello
i want to ask if the insertion of a record into a partion is slower than insertion it into a non partitioned table or not?
cuz sql has to decide to wich partion the record has to insert according to the partitioning key and is this decesion process is making insertion slower ?

Hi Experts,
I need to know the best approach to save data in master table and then in detail table.
I know this method but i know it's not a good approach why i will explain
Insertion in Master Table..................................... A
Insertion in Detail Table........................................B
Now if there is any exception occurred while step A then the step B will not take place which is ok but if there is exception while step B then the process A will have completed
i.e the data in master table will be Inserted/Deleted/Updated but there will not be a corresponding action in Detail table which is not good approach.
So please can any one tell me a good approach for this.

Hi there
I have a relatively noobish query and I am hoping to get a solution to it.
Heres the query in a nutshell.
I have a 'Type' table which has a 'TypeName' varchar attribute. So when I do a row insert into this Type table, I want a new table created with the value I insert into the 'TypeName' column as the table name.
For example If i insert 'xyz' into the 'Type' table for the 'TypeName' column. I wish for a trigger to fire which will create a table 'xyz' with some set attributes. I am really new to SQL Server and my preliminary googling left me disheartened with the results. So here I am.
I hope I was clear in the way I expressed my doubt and also that the people here might be able to help me out in this quest.

Hi,
This problem is connected with the query i posted yesterday regarding insertion of global variables. I was able to insert the variable in a table to check its value.
This value is mapped to the global variable in a previous Execute SQL Task. But when I use the same global variable to insert in a table, default value 0 is inserted.
My query is does the global variable declared at the package level does not store the value mapped across multiple tasks in control flow?
How can i insert the value stored in a variable in a table from previous SQL Task.
Can anyone suggest some solution,links to try a workaround?
Thanks in advance.
Regards,
Aman

I wanted to understand the basic difference between the following two MDX queries which give two different outputs -
1. Set of Tuples -
Query-
SELECT
[Measures].[Internet Order Count] ON 0
FROM
[ADVENTURE WORKS]
WHERE
[code]....
2. Tuples in a Set -
Query-
SELECT
[Measures].[Internet Order Count] ON 0
FROM
[ADVENTURE WORKS]
[code]...
From the output i am getting on the MDX, i understand that the analogy is not correct. But I am not able to understand the difference between the same.

Hi,
I found out that executing the procedure SP_INDEXOPTION and setting 'AllowRowLocks' to false i can prevent the sql server from locking rows in a table and 'AllowPageLocks' prevents from pages being locked. I need to preform same operation
in case of tables. I need to perform insertion operations concurrently and acquire required locks manually. Is there a way to stop sqlserver from acquiring locks on the table. I need to disable all the locks (row, page and table).
Thank you in advance.

I have a backup application that uses SQL as the backend (both 2000 and 2005) The backup application performs a specific function that enters data into the Database but does not have any reporting. I am looking for a way to query the DB directly to see if there is any info I can grab. But the problem is I don't know where its stored. So my questions) are:
Is there anyway to tell what tables get updated by a certain process. For example if I run this one action how could I then tell what tables were effected or even what data was changed. I tried looking for a logging function that would list this but did not find it. I also tried looking for some type of real time monitor. I even tried looking for a way to search for records / tables that had been recently updated.
I am new to SQL so not sure I am using the correct terms but any help would be appreciated. Also this is SQL2000 and a test server
Thanks in advance for your time

I need to update information for a user and if the user is classified
as a primary (@blnPrimary) then I need to update information for all
users within his agency (AgencyUniqueId). The issue is that the second
UPDATE to "cdds_User_Profile" always returns a rowcount of 0 (should be
1) even though the values for "@Original_AgencyUniqueId" and
"@Original_UserId" are correct. This is just a snippet of the whole
procedure. I'm trying to implement similar logic in other parts of the
procedure and I'm observing the same behavior there as well. Any help
anyone can provide is greatly appreciated. </p><pre>/*** Update User Profile ***/UPDATE [cdds_User_Profile] SET [FirstName] = @FirstName, [LastName] = @LastName, [Title] = @Title, [Phone] = @Phone, [AcctType] = @AcctType, [AcctStatus] = @AcctStatus, [LastUpdatedDate] = GETDATE() WHERE ([FirstName] = @Original_FirstName AND [LastName] = @Original_LastName AND [Title]=@Original_Title AND [Phone]=@Original_Phone AND [AcctType]=@Original_AcctType AND [AcctStatus]= @Original_AcctStatus AND [AgencyUniqueId] = @Original_AgencyUniqueIdAND [UserId] = @Original_UserId);IF @@ROWCOUNT = 0BEGINSET @err_message = 'Data has been edited by another user since you began viewing this information.'RAISERROR (@err_message,11, 1)ROLLBACK TRANSACTIONRETURNEND IF @@ERROR <> 0 BEGINROLLBACK TRANSACTIONRETURN ENDIF @blnPrimary = 1 BEGIN IF LOWER(@AcctStatus) <> LOWER(@AgencyAcctStatus)/*** Update Users Acct.

Hi,
I am trying to do selective updates for rows where a column matches a column in another table. I want to do something like this, only 'this' does not work, and nothing else I could think of (I tried joins also) worked. What am I missing? I hope this explanation makes sense.
UPDATE queryresultsmodel SET queryresultsmodel.tableforcedoutdate = getdate()
Where Exists (Select tablename from queryresultsmodel q inner join orphanul o on q.tablename = o.name)
Thanks for any help,

Hi,
Has anyone had any problems on one row updates on a table where you have defined horizontal and vertical partitioning of the data to be replicated?
When I execute an update clause that modifies just one row the log reader misses the modification and it does not get replicated to the other databases.
If I do the same update clause but on several rows then all the modifications are read by the log reader and the replication task goes ok.
What might be wrong?

Hi
I'm using VS'08 and develop in VB.
I'm using SQL CE 3.5 as a local cache for SQL'05 tables.
The table that's being updated uses an interger autonumber for the PK.
When the program starts up and inserts records into the table, it works, as long as no on else is insering recoreds into the same table.
Once a duplicate PK is created by another WS, the records no longer update the SQL'05 table.
If the blocked program is restarted, it'll insert records with a PK that's past the one found at the initial sync. until blocked again.
PK ---- ProgID ----- MSG

Hi. We're using SQL Server 2005 Express Edition for maintaining a relational DB for our soon-to-be released .NET app. The problem is that we expect that the definitions of the tables in the DB to occasionally change over time as we make updates to the software. Thus, during the installation of a software upgrade, we expect to run an SQL script that grabs the data from a table in its "old" format, re-structures the table, and then deposits the data back in the updated table. This seems to require some sort of version stamp on the table definition.
My main question is: What is the conventional way for handling versioning of table definitions?
Another question is: Is there a preferred procedure for handling the updating of the data during the installation of a software update?
Thanks.
Dave

Simple question:
I have two servers S1 and S2. Inmediately after new data on S1 is available I want to perform some actions on S2.
I can use a trigger on S1, but if S2 is down the transaction on S1 will be lost. I could use database replication but I only need one single table in S1 to report changes to S2
Is there any other approach I could use?
Thanks.

Hey, I have couple of triggers to one of the tables. It is failing if I update multiple records at the same time from the stored procedure.
UPDATE
table1
SET
col1 = 0
WHERE col2 between 10 and 20
Error I am getting is :
Server: Msg 512, Level 16, State 1, Procedure t_thickupdate, Line 12
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.
What is the best possible way to make it work? Thank you.

I am looking for pros and cons for the following scenarios:
When a table contains a unique key constraint is it viable to always do an insert and immediately check the @@ERROR value and if @@ERROR states a duplicate key exception then perform an update statement?
Another possible solution would be to always check if the key exists and then do the insert / update based upon that result. This method will always require two steps.

I was able to catch one update but not multiple updates or batch updates done to the table. I know the updated records are residing in inserted and deleted tables. Without using cursors, how can i read and compare all the rows in these two tables?
Following is the table structure:
Customer_Master(custmastercode, customer_company_name,updated_by)
Following is the trigger:
ALTER TRIGGER [TR_UPDATE_CUST]
ON [dbo].[CUSTOMER_MASTER]
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
IF EXISTS (SELECT * FROM inserted)
BEGIN
declare @custcode int
Declare @message varchar(5000)
Declare @custommessage varchar(2000)
Declare @CUSTMASTERCODE int
Declare @CUSTOMER_COMPANY_NAME varchar(50)
Set @message = 'Changes in customer account number ' + Cast ((@custcode) as varchar(10)) + ': '
select @custcode = [CUSTMASTERCODE],@UPDATED_BY = [UPDATED_BY] from inserted
Set @message = 'Changes in customer account number ' + Cast ((@custcode) as varchar(10)) + ': '
IF(update([CUSTOMER_COMPANY_NAME]))
Begin
select @UCUSTOMER_COMPANY_NAME = [CUSTOMER_COMPANY_NAME] from deleted
select @CUSTOMER_COMPANY_NAME = [CUSTOMER_COMPANY_NAME] from inserted
Set @custommessage = 'Customer company name changed from ' + @UCUSTOMER_COMPANY_NAME + ' to ' + @CUSTOMER_COMPANY_NAME + '.'
Set @message = @message + @custommessage
End
Set @message = @message + ' Updated by ' + @UPDATED_BY + ' at ' + CAST(getdate() AS VARCHAR(20))+ '.'
INSERT INTO [CHANGE_HISTORY]
([CUSTMASTERCODE]
,[CHANGE_DETAILS])
VALUES (@custcode, @message)
END
END

Facing deadlock issues in my ETL job .
The driver table , which keeps track of what datamarts ran and for what date range gets updated frequently during the etl run . There can be as many as 250 updates issued on this table in a single second.
Now this table is a heap , and there are no indexes on it .
During these updates , we encounter deadlocks causing the ETL job to fail .
Will adding an index faciltate?

I am basically trying to update a table which reflects account transactions. Accounts get paid in full but occasionally balance payments can be reversed and I want to update the table to show this - I need to show which period the account was previously paid in full.I've created a simplified version of the scenario and below are a couple of examples of things I've tried that do not work. I understand why they do not work but I'm struggling to figure out how to update the 'PeriodPrevPaidInFull' field.
create table Trans
(
AccNo int,
Transaction_Period_Index int,
PeriodOpeningBalance money,
DebtBalance money,
PeriodPaidInFull int NULL,
PeriodPrevPaidInFull int NULL,
[code]...
