Is It Possible To Read Data From A Table With Exclusive Lock ?
Sep 4, 2006Hello,
We currently use SQL Serv 2000 with an ERP application and VB applications.
Both system work with the same database & tables but the ERP application seems to put exclusive lock on all tables it needs during processes. So our VB applications are not able to read these data and we receive TIMEOUT error.
What can I do ?
thank you

Error: A Deadlock Was Detected While Trying To Lock Variable X For Read Access. A Lock Could Not Be Acquired After 16 Attempts
Feb 2, 2007I simply made my script task (or any other task) fail
In my package error handler i have a Exec SQL task - for Stored Proc
SP statement is set in following expression (works fine in design time):
"EXEC [dbo].[us_sp_Insert_STG_FEED_EVENT_LOG] @FEED_ID= " + (DT_WSTR,10) @[User::FEED_ID] + ", @FEED_EVENT_LOG_TYPE_ID = 3, @STARTED_ON = '"+(DT_WSTR,30)@[System::StartTime] +"', @ENDED_ON = NULL, @message = 'Package failed.

From progress:
Error: The Script returned a failure result.
Task SCR REIL Data failed
OnError - Task SQL Insert Error Msg

ERROR: A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List.
May 22, 2006Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:
OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.
Help would be appreciated!
I have seen other posts on this but, not able to relate the solution to my scenario.
A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List
May 10, 2006Hi All,
I have seen a few other people have this error.
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

Serializable Read And Lock Mode
Jul 20, 2005Hi,Version Info: SQLSERVER 2000 SP3I am trying to understand how SQL Server works with SERIALIZABLE read.I am fairly new to SQL Server, having mainly worked with Informix.We are getting lock timeout error in our application. Our lock timeoutis set to 20 seconds. I am trying to investigate why locks are held forsuch a long time in the first place.I believe SQLServer tries to put keylocks as much as possible forensuring serializibility. For e.g.SELECT column_bfrom table_awhere column_c between 1000 and 1100what if column_c has no index. Does it switch over the data row.And what if a table has no index. Will it go for table lock, as ituse to do in earlier versions.TIA.--email id is bogus

May 12, 2015I have a requirement to read a value from table and increment it by 1. There can be multi-threads doing the same operation and would need a ROW LOCK so that read and write both are atomic. How can i put an exclusive lock on the row before I read the value from the table.
CREATE TABLE [dbo].[tblOnboardingSequence](
[OnboardingSequenceID] [uniqueidentifier] NOT NULL,
[Name] [nvarchar](255) NOT NULL,
[NextNumber] [bigint] NOT NULL,

)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
My Stored Procedure has below logic
DECLARE @NextNumber BIGINT
----------- Acquire row lock here
SELECT @NextNumber = NextNumber FROM tblOnboardingSequence WHERE Name = 'TPO'
UPDATE tblOnboardingSequence SET NextNumber = @NextNumber + 1 WHERE Name = 'TPO'
----------- Release row lock here
I would like to have a row lock for the row having Name "TPO" before SELECT query and release after UPDATE query.
What si the best way to deal with this?
Writes Are Not Commited Right Away
Mar 25, 2008Hi!
First of all I want to tell you that I'm not a dba or tuning expert but I've ran a trace on a database with perfomance problems and I've found a strange thing.
The user creates orders for their service people in the organisation. I can see in the trace that inserts are done but they don't produce any writes rightaway. However after 10-15 minutes all the writes are done, what could make the actual write be delayed so much. The application is developed using .net.

For example suppose I have one table called tbl and one session is updating one records and not committed yet and in other session if i execute select * from table I can see all the records, for that records it can show me older version. but my select statement should not wait to commit another session and also it should not show the modified data.
View 4 Replies View RelatedRow Lock Versus Page Lock In SQL 2000.
Apr 7, 2004Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
Please advice. Thanks a bunch.

Lock On Table While Inserting Data In Database
Jul 10, 2014I have question on lock on table in SQL Server while inserting data using multiple processes at a single time into same table.Here are my questions on this,
1) Is it default behavior of SQL server to lock table while doing insert?
2) if yes to Q1, then how we can implicitly mention while inserting data.
3) If I have 4 tables and one table is having foreign keys from rest of the 3 tables, on this scenario do I need to use the table lock explicitly or without that I can insert records into those tables?
Bulk Insert Data In Millions - Lock Issue
Oct 11, 2005Hi all,Hope there is a quick fix for this:I am inserting data from one table to another on the same DB. Theinsert is pretty simple as in:insert into datatable(field1, field2, field3)select a1, a2, a3 from temptable...This inserts about 4 millions rows in one go. And since I had the'cannot obtain lock resources' problem, several methods were suggestedby some web sites:1) one to split the insert into smaller chunks (I have no idea how Ican spit a insert to insert only n records at a time..)2)to use waitfor - which I did but did not fix the error.3)use bulk insert (in t-sql) - I dont know how to do this?As I see I am simply trying to move data from one table to another(ofcourse lots of data) in SQL Server 2000 and I dont see one simplesolution to the locking problem.any ideas on how best I can do this will save my day!thanks all.

SQL Security :: Making Data Change In Read Only Database Without Letting Other Users Update Data
Aug 6, 2015I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.
For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database
single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?
Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.
The code;
use master
alter database xxx set read_write
with rollback immediate
alter database xxx set single_user
with rollback immediate
use xxx
update tablexxx set columnxxx=yyy
use master
alter database xxx set read_only
with rollback immediate
alter database xxx set multi_user
with rollback immediate

Populating An Access Combo Box With Large Amount Of Data Causes Table Lock In SQL Server
Jul 20, 2005I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)

XML Data Read Help
Sep 12, 2007I am having issues in figuring out how to read part of an XML file and I'm not sure if it can be done. Any and all help would be appreciated.
I have a file resembled this way:
<btb-root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" btb-num-trans="2"
btb-date="2006-11-09" btb-time="22:40:03" btb-sender="TTT"
btb-receipient="Test">
<btb-request req-method="Asynchronous">
<req-header>
<req-btb-id>Test</req-btb-id>
<req-client-id>Test</req-client-id>
<req-product>Test</req-product>
<req-loan-number>Test</req-loan-number>
</req-header>
<req-property-address>
<addr1>Test DR</addr1>
<city>Test</city>
<state>Test</state>
<zip>Test</zip>
</req-property-address>
<req-borrowers borr-type= "Borrower">
<first-name>Test</first-name>
<last-name>test</last-name>
</req-borrowers>
</btb-request>
</btb-root>
I am in need of extracting the date "2006-11-09" to a field in an import table contained in a sql database. I can pull all the other fields I need but in SSIS retrieving the date is not an option that I currently see. Does anyone know a way around this?
Thanks

What scope does that command affect?2. Could someone write some real world example where i should neverread uncommitted data... i'm having trouble understanding when ishould and when i should not use it.
View 7 Replies View RelatedHow To Share Read Only Data
Jun 15, 2007Hi,
I'm new to replication. Can anyone help with the following?
I want to publish the specific rows of data that are created on the publisher without accepting changes to those rows from subscribers, but do accept new rows (and changes to those rows) from subscribers.
EG. publisher creates rows 1 and 2 which are published to the subscriber
subscriber creates rows 3 and 4 which are merged back to the publisher
subscriber's updates (or delets) to rows 1 and 2 are not merged back to the publisher
So basically I want the publisher created rows to be published but remain as is whilst allowing subscriber created rows to be merged back to the publisher.
Hope is makes sense.
Thanks in advance,

How To Lock A Table So Others Cannot Lock It
May 23, 2001Hi,
I want to lock a table so others cannot lock it but able to read it inside transactions.
The coding I need is something like this: set implicit_transactions on begin transaction select * from table1 with (tablock, holdlock) update table2 set field1 = 'test' commit transaction commit transaction
I have tried the coding above, it won't prevent others from locking table1.
So, I changed the tablock to tablockx to prevent others from locking table1. But this will also prevent others from reading table1. So, how can I lock table1 so others cannot lock it but still able to read it?
Thank you for any help
