How Does One Set Read-uncommitted On The Entire DB?
Mar 1, 2006Rather than setting by session I would like to configure the DB as read
uncommitted.
Thanx Advance.

Set READ UNCOMMITTED (dirty Read) At Login.
Jul 23, 2005Is it possible to set READ UNCOMMITTED to a user connecting to an SQL2000 server instance? I understand this can be done via a front endapplication. But what I am looking to do is to assign this to aspecific user when they login to the server via any entry application.Can this be set with a trigger?
View 1 Replies View RelatedAppropriate Use Of READ UNCOMMITTED?
Jul 20, 2005I haven't used the READ UNCOMMITTED transaction isolation levelbefore, and I was wondering if this would be an appropriate use:I have an ID table containing ID numbers that are randomly generatedand need to be unique. There is a stored procedure that potentiallygenerates thousands of these IDs in one execution and inserts theminto the ID table and various other tables. The basic idea is asfollows:Begin TransactionWhile not all IDs generated {GenID:@NewID = GenerateID()If @NewID exists in ID tableGOTO GenIDInsert into ID tableInsert into various other tables}Commit TransactionThe problem occurs when the stored procedure is being run by more thanone process concurrently. The check to see whether @NewID exists inthe ID table will block, waiting for the transaction in the otherprocess to commit.Would this be an appropriate place to use the READ UNCOMMITTEDisolation level to allow different executions of the stored procedureto see what the others are writing into the ID table before thetransactions finish? I only really care that the IDs generated areunique; they're not in sequence or anything like that. Has anyone hadexperience with anything similar?

Jul 5, 2005Are there really any benefit on using Read Uncommitted Isolation Level or having a NOLOCK hints for retrieve queries when the default Isolation level just Read Committed (not using COM+). I'm confused why the Community Server uses this technique perhaps for perf issues but I couldn't see any reason why...
View 1 Replies View RelatedSelect With (nolock) OR TransactionScope With Option Read Uncommitted Data
May 29, 2007Hi Sql gurus :))I've got a question that I couldn't find a satisfying answer on the net.What is the difference between:1) running sql query (select from sth with nolock) with no transaction2) running sql query (select from sth) withing a TransactionScope with option Read Uncommitted dataBasically, both should do the same work. However is anyone aware of any potential problems using any of both approaches ?We use 1) to improve our web application scalability since the system works in such a way that any selects and updates on that table (sth) do not interfere with one another.However, updates are done in a TransactionScope. And when having simultaneous select with nolock and update in a Transaction scope (the select statement has a where clause and returns records that are not updated by the update statement). However sometimes ( we still cannot figure it out when) the select statement returns some records twice.For example, the select should return 1000 records , but (sometimes) it returns 1002 records ( the extra 2 records are copies of some of the original 1000 records).Removing the nolock, makes the problem does not appear - but i want to be 100% sure that nolock is our troublemaker. And if it is - why ?We also have a problem that this particular nolock select sometimes return even less records than it should.I know it sounds impossible but it happens.So anyone who has experience with select with nolock, please share :)Thanks in advance, Yani
View 4 Replies View RelatedLocks Caused By Long Lasting SELECT, Could It Be Solved By Read Uncommitted?
Jan 15, 2008Hi,
Yesterday, we have had a sudden load in our SQL Server 2000 which resulted in several locks. There was not too much time to investigate as we had to rush. A team member had reviewed the processes in EM, Manegement, Current Activity. Looking for blocking processes and killed them.
She told me that as soon as the blocking SPID was killed, another one arose and she had to repeat the operation a dozen of time. When done, the server activity was back to normal. She noticed that more than half of the blocking processes showed that they executed the stored Proc "P_SearchProducts".
We don't own the server and the information on what had happened at that time (batches or resource intensive operations, etc.) is not available for now.
The team suggests that we set the Transaction Isolation Level to Read UNCOMMITTED for this SP. I would like to know better about locks before I go ahead.
P_SearchProducts returns 5 recordsets each one could contains from 1 to 200 rows. To achieve the results, it creates about 10 intermediate tables (SELECT ... INTO #TableX) these temp tables are then used progressively to arrive to the final results. Roughly the volume of these temp tables could be double than the final results. The developer who wrote this SP is not a guru in SQL, there is room for improvement. But here are my questions:
Q1. Could the series SELECT ... INTO #TableX in P_SearchProducts prevent or lock another connection from executing the same SP? If yes, under which conditions?
Q2. Let's assume that P_SearchProducts has a slow execution time. Could it prevent another connection from updating the Product table? And thus leading to a deadlock situation? Something like another transaction (by User2) has obtained lock on most of Product tables, except the Product table which were being slowly read by User1 executing P_SearchProducts. But User1 cannot read the other product tables b/c there are locks by User2.
Q3. If the contention issue was provoked by the slow execution time of many request to exec
P_SearchProducts (let's assume there were suddenly 50 users on the web hitting the search product feature at the same time). Could the Read Uncommitted magically resolve the contention issue, providing we accept the consequences of the dirty read.
Sorry for the long post and thank you in advance for any help.
Fail To Read Entire Table In .NET
Sep 20, 2007The problem that I am having is that I am not getting the results from an entire table, just a small subset. The sql command is "Select * from login", which has always implied to me, get everything, to end of table, or, until I tell you to stop. I am getting exactly, 10 items as input, and then it stops. I am including the code below in the hopes that someone can spot what it is that I am doing wrong.
The purpose of the routine is to convert a user login database into a new, expanded format.
TIA, Tom

Uncommitted Transaction
Oct 19, 2007
Dear friends,
Transaction means the actions user perform in a database, like create table, update, select. Is that correct? Can back up or restore be transactions?
I recently read the tool-kit book and encountered 'uncommitted transactions' many times, esp. in the chapter of 'Backup and Recovery'. For example, today I wanna backup my database by backuping a full database, then three hours later performing a differential backup, and five mins later do transaction log backup. Then I restore those backups following the same sequence. When I restore diferential backup and log backup, I have the option to use one of the three options:
Leave the database ready for use by rolling back the uncommitted transactions. Additional transaction logs cannot be restored. (RESTORE WITH RECOVERY)
Leave the database non-operational, and do not roll back the uncommitted transactions. Additional transaction logs can be restored. (RESTORE WITH NORECOVERY)
Leave the database in read-only mode. Undo uncommitted transactions, but save the undo actions in a standby file so that recovery effects can be reverted. (RESTORE WITH STANDBY)
In the definitions above, 'uncommitted transactions' are all mentioned.
I do not understand why uncommitted transaction happned during or before or after backup( in my opinion, all transactions should be committed before you doing backup)? Can you please give me an example?
Thank you
Julian
SQL Server 2005 Hanging - Selecting Uncommitted Data
Dec 5, 2006We have found an issue with using MSS 2005 with odbc connections, some of
our code inserts data, then reselects the data back with a select using a
different handle. This hasn't caused any issues before but in one customer
this causes a lock up. The timeout error doesn't occur as you would expect
if trying to select data that is uncommitted by another user.
Although obviously we could re-code to avoid selecting uncommitted rows, can
anyone tell me why this works sometimes but not others. Some kind of
setting in MSS that we're unaware of maybe. The code works ok on other MSS
2005 & MSS 2000 servers and oracle & sqlbase.

Feb 13, 2006Hello,
i have a problem that i don't understand why it occurs: i have a package like this (resumed and ordered by its correspondingdata flow):
1. move data files to a path through by a file system task
2. import data of data files to a sqlserver database (each file through its own data flow). The origin of data is in files that have been moved to the path of step 1
3. execute a procedure of database (sql task) to manipulate data and finally export resume (data flow) to a new file in the path (moved by other file system task)
PROBLEM: if i execute the package task by task (one by one), it runs ok, but then when i build and run package as a whole (debug), it produces an error in the data flow such as it doesnt' find the path to take data of data flow (it doesn't find the source). Really it doesn't find source because the data files aren't in its correct path (like step 1 had failed). In summary, it looks like if the order of the task of package aren't correct when i execute the entire package, because the log doesn't thread any error about step 1 (file system task).
ERROR MESSAGE: an OLE DB error has occurred. Error code: 0x80040E37

Searching An Entire Database
Dec 28, 2005Hi, this is my first post on these forums, so please excuse me if this topic has already been covered.
I'm currently working in a power station for student vacation work placement. I need to export data from a database that gets it's data from machinery and inputs out in the plant. The machines that provide this input put it into a database, and I need to find the relevant data to export.
My problem is that, in some cases, the sample data that i'm given may be under different field names, in a completely unrelated table. I was looking for a way to search the entire database (250+ tables) for a certain string, so I can find where it is in the database, and run queries on the table it originates from. For example:
My sample data shows me that I have an object with the ID Y03A3DEA_TH1. I know this ID will occur somewhere else in the database, but i'm just not sure where.
If anyone knows of any way that I can search the entire database for specific data, either using tools in MS SQL 2000, or 3rd party apps, i would greatly appreciate their help.
Thanks a lot,
Jack Smith

Feb 4, 2008
Hi,
Is it possible to copy a database from the existing database. I mean to say creating a duplicating database.
Note: I can do it by using "Generate SQL Server Script Wizard" or "Database Publishing Wizard" which saves a some filename.sql and later executing this will create another database by assigning some xyzdatabase name.
My main motive is copying a database in a single line script without using this lengthy sciprt.
Example
FirstDatabase (contains 10 tables 10 stored procedures)
SecondDatabase (also contains 10 tables 10 stored procedures)
If possible, can you write a script that attach a database from the C:MyTemporaryDatabase
Because this i need through programming Visual Basic using SQL Server. I want to create some temporary database.
Waiting for your reply.
Thanks.
Best Regards
