What Happens With Two Transactions Changing Same Row Data
Sep 23, 2015
If I have an ACID-based SQL engine and I run a long-running transaction that changes a record at some point during the transaction, and at the same time it's running another transaction changes a record that the long running transaction has/will change/d, will they both complete or will one transaction fail? If they both complete who wins the final state of the record? The long running one or the other one? (is it based on when the transaction actually started "point in time" or is it specific to when the record was changed during the transaction "point in time"?)

Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

I am running SQL2k on Win2k sp1. I need to match a transaction record (using txn_date) to client data as it would have appeared on the date of the transaction (using client_last_update).
A new row is inserted into my client table every time any part of the clients information changes, thereby leaving the change history in tact. The client_last_update field holds the date the change took place. It is required that the user be provided the client information that was current on the day of the transaction.
Example: A client record (name, address, accountno) was inserted to the client table on 2/1/2000 (the last_update field is empty because it's a new record).
The client record is modified on 4/15/2000 for a name change (making the last_update = 4/15/2000), and again on 12/5/2000 (making the last_update = 12/5/2000).
Transactions are made by the client on 2/5/2000, 6/10/2000, and 3/25/2001. These dates are held in the txn_date field in the transaction table.
The client now has 3 transaction records in the transaction table for his/her account number and 3 client records in the client table.
The transaction on 2/5/2000 should be joined to the initial client record ((2/5/2000 > empty) AND (2/5/2000 < 4/15/2000))
The transaction on 6/10/2000 should be joined to the client record having the last_update = 4/15/2000 (6/10/2000 > 4/15/2000) AND (6/10/2000 < 12/5/2000))
The last transaction, executed on 3/25/2001 should be joined to the most current client record, which has last_update = 12/5/2000 (3/25/2001 > 12/5/2000).
I have been experimenting with the code below, and found it to only return client data where the client record update_date = '4/18/2000'.
select * from transaction t Left Outer Join client c On t.SEC_ACCT = c.Account_No and t.Txn_Date > coalesce(c.Last_Update_Date, '1/1/1900') and t.Txn_Date < (select min(c2.Last_Update_Date) from client c2 where c2.Last_Update_Date > coalesce(c.Last_Update_Date, '1/1/1900'))
An example of a record that DID get returned carried a txn_date of '1/2/2001', and possible client update_dates of: NULL, '5/13/1999', and '4/18/2000'. The row returned carried a client update_date of '4/18/2001', and rightly so.
An example of a record that DID NOT get returned carried a txn_date = '1/2/2001' and possible client update_dates of: NULL, and '6/11/1999. This row was not returned.

Multi user ASP.Net website, SQL Server backend.When using transactions to insert multiple rows into a table and then commiting them once you're happy that everything looks good, the table(s) gets locked before commiting.Basically, I want to perform updates and inserts under a transaction but still allow other users to carry on using the site and potentially the tables that are being used with the transaction.
Question: Is there a way to stop the table lock occurring and for SQL to just do a record lock?, thus avoiding blocking other users?I know that a possibility is to use Snapshot replication, but am a little worried about turning it on due to the small team we have for testing.

Hi, all experts here,
Do we always have to use SCD component for the loading of data into data warehouse to handle changes of rows?
I am looking forward to hearing from you and thank you very much in advance for your help.

I have a fairly simple data flow task that loads data from one table (OLE DB Source) into another table (OLE DB Destination). The data type for one of the pairs of columns is nVarChar(120) and it contains version information that looks like a decimal. When I run the export, the destination has a trailing zero added after the decimal point as if it were a numeric column which invalidates our comparisons (string 1.0 is not the same as string 1.00). There is no cast or convert done to this column, it is a straight copy. Any ideas what could be causing this or how to fix?

I have created a SSIS package that transfer data from a Foxpro database to an instance of SQL Server 2005 Express. I used the wizard to create the package but I load and execute the package within a custom application that I have written in C#.
The way the custom application is intended to work is that the user can have the database in any location on the computer and all he has to do is specify the location then the application programatically changes the location of the source on the package that it has loaded and then execute it. When I initially run the package the first time (using the original path), it works fine and transfers the data. However, every subsequent time I run the application and specify a different path, the database on the SQL Server side gets created as expected but the data is not transfered!
Where am I going wrong? Do I need to save the package after I modify the source then reload and run it again or do i need to change something else in the Data Flow to make this work?

I have a very long transaction that runs on the same database thatother users need to use for existing data. I don't care if they seedata from the transaction before it is done and am only using thetransaction because I need a way to roll it back if any errors happenduring the transaction. Unfortunately all tables affected in the longrunning transaction are completely locked and nobody else can accessany of the affected tables while it is running. I am using thetransaction isolation level of read uncommitted, which from my limitedunderstanding of isolation levels is the least strict. What can I do toprevent this from happening?Below is the output from sp_who2 and sp_lock while the process isrunning and another process is being blocked by it.SPID Status LoginHostName BlkBy DBName Command CPUTimeDiskIO LastBatch ProgramName SPID----- ------------------------------------------------------------------------------ ---------- ----------------- ---------------- ------- ------ ------------------------------------------ -----1 BACKGROUND sa. .

I am having a problem getting error rows to redirect between an OLE DB Source and an OLE DB Destination when using transactions. Each time I turn on the transaction control I get an error stating:
"[OLE DB Destination [48]] Error: The input "OLE DB Destination Input" (61) cannot be set to redirect on error using a connection in a transaction."
I get the above Error when using MSDTC. I have the data flow inside of a Sequence Container with the transaction option set to REQUIRED and the Isolation Level set to Serializable. I have tried all the Isolation levels.
I have the error rows piped off to a seperate OLE DB Destination. I have also tried using native SQL transactions with Execute SQL tasks to BEGIN, COMMIT or ROLLBACK the transaction. This does not work either. It looks like it works properly when the data flow is successful but using profiler I can see SSIS opens up a seperate process for the BEGIN and then another one with the Data Flow task. When I intentionally fail the Data Flow the Rollback always fails. I made sure I had RetainSameConnection turned on for the Connection I was using.
I am speculating that the Data Flow does not know what to Rollback the actual rows that succeeded or the error rows that are getting piped off.
I am fairly stumped on this one so any help is appreciated.
Thanks

Client is running X- version of application and corresponding database size is huge. Now client's vendor is releasing Y-version of same application with many database schema changes (like new tables added, new columns added, renamed existing columns and etc) To upgrade to the Y-version, vendor is suggesting to my client that down the system and do the upgrade for application/database to Y-version. We are sure that this process will take days together to upgrade to the Y-version. My client is not ready to down the system for that long. So we are trying to find the solution with minimal down time.The approach we are thinking is,
1) Create the replicated database to another server (server2) from production server(server1) using golden gate with X-version
2) Create new tables/schema updated tables from Y-version database on same server1. Here for Updated schema tables we are planning to use the name <table_name_Y_version> as the same table name exists in X-version.
3)With above 2 steps, golden gate replicate the changes from production to server1 and server1 will have the new Y-version table schema (with different concatenate name ' _Y_version'). BTW , there is no affect for the production
4) At this stage we are planning to find best approach, to fill the '<table_name>_Y_version' from X-version tables. two challenges here a) all data needs to be moved to Y-version tables b) they have to sync data in real time.
we thought of going to
a) ssis package to pump the data to Y-version tables, but real time data will not sync.
b) trigger based technique, previous experience said, lot of load
c) thinking about sql replication.

Please HELP!
I need to UPDATE a column by removing only the first occurance of $$sp;. I use the following to get an idea of what I have:
SELECT Reporting_Title_Html FROM Lab_Test Where RTRIM(Reporting_Title_Html)='$$sp;'
Reporting_Title_Html
------------------------------
$$sp;
$$sp;
$$sp;
$$sp;
$$sp;Thyroid maintenance required;$$sp..........
Get 5 Records....One record has multiple occurances of $$sp throughout the Reporting_Title_Html column.
I thought I could do:
Update Lab_Test Set Reporting_Title_Html=' ' Where RTRIM(Reporting_Title_Html)='$$sp;'
But I can't lose the trailing data from record #5. This is just a small sampling of what I'm trying to fix.
Any Ideas???
I've thought about REPLACE but that would replace all the $$sp's and I only want to change the very first one from $$sp to ' ' --> blank

Hello,
I'm working on a distributed application which requires data from a central database to be shown to various users. In particular users should be able to open "views" on the database, specifying the data they are interested in, and being shown the result.
This can be easily accomplished modeling the view specifications as SQL select queries, sending those queries to the server, and visualizing the result. This approach is very flexible, supported, fast and definitely the way we would like to implement it.
The problem is that we have an additional requirement.
In general the data the users might be interested in is not static, and when that data changes, those changes should be propagated to the client views.
There are lots of solutions and technologies aimed to solve very similar problems, but no one seems to support this scenario well.
1. You can re-run the queries every x time (polling)... but this is hardly an option when you have hundreds of client-views that require data to be updated in real-time (so "x time" should be, say, 1 second).
2. You can use query notification... but the documentation explicitily says it doesn't scale well and shouldn't be used with a large number of clients (which is exactly what is needed in this case).
3. You can use replication services... but this technology doesn't really seem to be created to support this scenario.
4. You can use notification services... but even this technology seems to be focused on different scenarios. I haven't looked at it extensively anyway.
5. You can use DML triggers to track data changes... but you still don't have the publish-subscribe mechanism to register client views and the mechanism to know which client views are affected by the changes.
6. You can implement a business logic tier that relates modification requests to client views... and basically do everything from scratch without using existing services.
What are your opinions?
Thank you,
Lorenzo Castelli

Use databases a bit, but new to SQL Server. We just want to change a column of existing SQL Server 2005 data from a string data type to one of the UNiCODE data types, such as DT_WSTR or DT.NTEXT (such as one can use for various data mining tasks, etc.). It seems to do this one needs to "the data conversion transformation editor". To use that one has to have a package and a project?
Does any one have a full script or set of steps to do the full set of steps for what should be a simple task? This would be a great example for BOL, but each atomistic bit of BOL refers to another, and one gets lost in the circle when a complete example is needed for fundamantal housekeeping tasks.

Hello all,
I am trying to modify the output of a SELECT statement in a VB asp.net page that pulls data from a SQL DB. I only need to modify one column in the gridview, but I'm having some issues.
Here is the situation:SELECT TOP 24 ID, RecID, Timestamp, Answered, Holds, Dropped, Waits, Voicemail, Busied, LiveWaitsFROM mTrafficORDER BY Timestamp DESC
The Timestamp column returns a number value (i.e. 564566).In terms of a date, 564566 doesn't mean anything to the user, so I need to convert this number into a recognizable and accurate date.
The formula I need to implement is Timestamp/1440 - 1
The following SELECT statement returns the number as a date, but makes all records the same date:
SELECT TOP 24 ID, RecID, Convert(datetime, Timestamp/1440 + 1) as Timestamp, Answered, Holds, Dropped, Waits, Voicemail, Busied, LiveWaitsFROM mTrafficORDER BY Timestamp DESC
What do I need to do to implement this function dynamically into my gridview?
Thanks in advance!

We have a SQL Server setup as a publisher to 15 subscribers. We need to change the path of the data & log files to a new drive (added a new harddisk). We plan to take a cold backup of the database and shift the data & log files to the new drive. Then we just attach the data & log files from the new path.
Will this disturb my existing replication Setup?
Is the the correct procedure for changing the path of the existing data & log files?
What is the appropriate method for shifting data & log file of a live database to a different location (directory/drive) ?
thanks in advance

I've got a customer who wants reproducible/historical reporting. The problem is that the underlying data changes.
I tried to explain that this can't be done (can it?), but he doesn't
understand.
To illustrate the situation - Let's say a teacher wants to track
spelling test scores for her students.
The below are scores for students A, B, and C (for January, February, March)
A: {70,80,85}
B: {70,65, 80}
C: {100,90,100}
So, I can generate a historical report that charts the class average
and student trend - that's pretty easy.
Now, in April, we find that the school board has mandated that the
British spelling of words is ok, so now the cumulative scores (for
January, February, March, April)
A: {90,80,85,100}
B: {80,65, 80,80}
C: {100,90,100,75}
He wants a report showing the January average as (70+70+100)/3 = 80,
when really it is (90+80+100)/3 = 90.
Now imagine that there are actually thousands of data points changing like this...
Now also imagine that we add and remove students on a regular basis...
He and his office manager get frustrated when I explain that the
reports are not simple - in their mind it is. They have determined
the solution is to get a report writer and buy Crystal Reports...
I've tried to explain that the problem is that the report
specification is unclear (basically - they don't understand what they want). The situation is ok for now, I'm just trying to plan for when they figure out that buying Crystal Reports won't change their situation (except they are done several thousand dollars)...
Any tips?

Hi,
I was wondering how to modify a column's properties, like its datatype or length.
I know I'm supposed to do something like this:
ALTER TABLE MyTable ALTER COLUMN MyColumn int(20)
My main concern is, what will the database do to all the data in the column, if the column used to be, say nvarchar(50)? Will I lose the data in the column if I change the datatype? And what if I had data in this column that was longer than 20 characters? Will the data now be truncated? What can I do to make sure that nothing happens to the data once I change the datatype?
Any help would be greatly appreciated! Thanks! =)

Hey all,I have a basic table that looks something like this.CREATE TABLE MyTable(ID INT IDENTITY PRIMARY KEY,Company_ID INT NOT NULL,Round VARCHAR(50) NOT NULL,Details VARCHAR(250) NOT NULL)It has a few rows of data that look like this:Identity Company_ID Round Details--------------------------------------------1 5 A Blah, blah.2 5 B Generic data, blah blah.3 5 WERT More generic blah blah.Now what i'm trying to do during my select statement is select all the rowsthat belong to company_id 5 but if any of the rows round value contains thetext "WERT" convert that text into just a "--" for presentation purposes,but still select that row. I can't seem to figure out how i would transformthe text in the select statement? My immediate thought was substring /replace but i would need to combine it with an if else statement which i'veno idea how to make work in a select (sub-query maybe?) statement. Is thispossible? Perhaps i'm stuck iterating through the returned data within theclient application before presenting?Any help, as always, would be greatly appreciated.Muhd

How do i change data type settings in when building my tables?
Specifically i want to reduce the number of decimal places on 'smallmoney' so it doesn't show 4 but rather 2. Thank you.

Is there a way to change the physical mapping of a user defined data type to the physical SQL Server datatype. It seems that once you create them, it is just about impossible to change it.
Thanks,

Hi,
I have a sql server 7 running on a machine with two disk partitions (D: and E:).
The data files xxx.mdf and xxx.ldf are stored in D:, which has very few space available. I want to copy these files to E: but I get an error saying that it is not possible to change the source file of a database. Is it possible to do it or do i have to create another data file in E: and keep the old one in D:?
Thanks in advance,
browser

I have tables that I want to fire either an update or insert trigger on.I could write a script containing a long list of inserts but I'm looking forsomething simpler. Would isql work? Any special conditions to get it towork?I've tried tricks like 'update x set col = col' or 'update x set col = col +'' 'All the alternatives seem to have problems.

Thanks in adance
Platform: SQL 2000
A SQL table has a field named "pay-day" with Char(8) data type.
I tried to change its data type to datetime but only with an error message like this. I did right-click the table and tried to modify a data type.
- Unable to modify table.
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
The statement has been terminated.
Jay
