Sql Update Statement
Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other. Join them; it only takes a minute: Sign up Data has always changed(SQL Server Management Studio) up vote 0 down vote favorite I am using SQL Server Management studio and keep getting the same error, and the only way to https://support.appliedi.net/kb/a299/you-may-receive-an-error-message-when-you-try-to-use-sql-server-management-studio.aspx get rid of it(usually) is to reset the SQL server(which is very annoying, and sometimes impossible from my remote machine) When I add a row to a table, and then I goto "Edit Top 200 Rows" it all displays and acts fine, and I go to a field I want to change. Then I change something like 0 -> 1 and then I get a nice friendly popup saying "Data has changed since the Results Pane was last http://stackoverflow.com/questions/1457676/data-has-always-changedsql-server-management-studio retrieved... Optimistic Concurrency Control Error" If from here I say "Yes to commit changes to database anyway" I get "No row updated... The updated row has changed or been deleted since data was last retrieved" It's a very annoying little thing, cause I don't like having to look up RIDs and then make an update statement(and possibly having to worry about escaping 's by hand) Is there some way to turn this concurrency checking off or something? I know the row wasn't updated or anything, and I tried completely closing Sql Server Management Studio and reopening to no avail, and also tried refreshing the result pane, or refreshing the column view. Nothing gets rid of this error, but if I do a "update ... set ...=..." then it works, so I'm not really having any concurrency error.. sql-server concurrency share|improve this question asked Sep 22 '09 at 1:13 Earlz 25.8k56207401 Is this any table or one specific table? Does it have a timestamp/rowversion column? –MartW Sep 22 '09 at 1:25 No, it has neither of those columns, This tends to happen with some tables more than others(when one table is broken, others can still work though), but I would expect if I edited every table as much as this one, I would get the same thing for every table. –Earlz Sep 22 '09 at 1:30 I found kbalertz.com/925719/&hell

Solved Optimistic Concurrency Control Error Posted on 2006-06-29 MS SQL Server 1 Verified Solution 20 Comments 1,209 Views Last Modified: 2011-09-20 Hi, sql server I have a table X: ID (PK, int, not null) cstID(FK, int, not null) Name( nvarchar(100),not null) Desc( ntext, null) I am using the table view in Enterprise manager, if I manually type in a new row, then I edit that row, setting "Desc" = NULL, then I delete that row (from within the table view) I get the error: Data has changed since the data in the results pane was last retrieved. Do you want to save your changes now? (Optimistic Concurrency Control Error) Things to note: There was a FTI on this table, I deleted it, didn't help. No other process or users are editing/viewing this table The error doesn't occur if edit any other column, just setting the "Desc" to NULL creates this error. Some other tables in my DB exhibit this same behavior, but not all......I can't figure out what the heck is going on...can you? 0 Question by:thomp361 Facebook Twitter LinkedIn Google LVL 40 Active today Best Solution byVadim Rapp if you click on another row, then the fact that you updated the first one should not matter - once you left the updated row, it's committed.

Versioning Concurrency in SQL Server 05 June 2014Row Versioning Concurrency in SQL ServerThe optimistic concurrency model assumes that several concurrent transactions can usually complete without interfering with each other, and therefore do not require draconian locking on the resources they access. SQL Server 2005, and later, implements a form of this model called row versioning concurrency. It works by remembering the value of the data at the start of the transaction and checking that no other transaction has modified it before committing. If this optimism is justified for the pattern of activity within a database, it can improve performance by greatly reducing blocking. Kalen Delaney explains how it works in SQL Server. 32 3 Kalen Delaney By default, SQL Server adopts a pessimistic approach to concurrency, acquiring locks in order to avoid read phenomena such as dirty reads, non-repeatable reads and phantom reads, depending on the required ANSI isolation level. As a result, readers block writers and writers block readers. However, the ANSI SQL definitions of each of the transaction isolation levels specify only which of the behaviors each level allows, not how to implement them. Under an alternative concurrency model, enabled via snapshot-based isolation, SQL Server can prevent some or all of these read phenomena, depending on the mode of snapshot-based isolation in use, without the need to acquire locks, therefore greatly reducing blocking in the database. In order to achieve this "optimistic" concurrency, SQL Server uses a row versioning technique, whereby it stores in tempdb copies (versions) of all the previously committed versions of any data rows, since the beginning of the oldest open transaction (i.e. it keeps those copies as long as there are any transactions that might need to access them). The space in tempdb used to store previous versions of changed rows is the version store. When using this row versioning, readers do not block writers, and writers do not block readers (though writers do still take locks and will block other writers). In this article, we'll discuss: row versioning and how it works snapshot-based isolation, the new modes of operation it introduces, snapshot isolation (SI) and read committed snapshot isolation (RCSI), and how they work the potential for update conflicts in SI mode monitoring and managing the version store - especially disk space usa
