RowVersion/Timestamp To String

Feb 12, 2008

I have a RowVersion/Timestamp column in my table. I check against the RowVersion/Timestamp column when updating rows to check if a row has been updated by another user. I would like to call RAISERROR with a custom message which indicates the current RowVersion/Timestamp of the row in question.

What data type do I convert the RowVersion/Timestamp column into so I can make it part of the custom message which will be a string?

If I convert the RowVersion/Timestamp column into a bigint column, will the max value of RowVersion/Timestamp ever exceed the max value of a bigint? For example, convert(bigint, MyRowVersionColumn)

If the max value of the RowVersion/Timestamp column can exceed the max value for a bigint column, can I convert the RowVersion/Timestamp into a hex string?

Basically RowVersion/Timestamp columns are binary(8) or varbinary(8) so the question could also be answered if it is known if binary(8) can exceed the max value of bigint or if binary(8) can be converted into a hex string

Any help would be appreciated, Thanks!

SqlDataSource And Timestamp(Rowversion) Datatype

Mar 28, 2006

Hello, I'm attempting to use the Sql Timestamp (Rowversion in 2005) datatype for optimistic concurrency for my SqlDataSource because the table I'm updating has a few columns that can be null which breaks the optimistic concurrency code generated by visual studio. However, the Type's available for SqlDataSource parameters do not include "Timestamp" and everything else I've tried throws exceptions. SO, is there anyway to use the timestamp/rowversion datatype with a SqlDataSource? Many thanks for your help, I have been googling this for literally hours. Thanks again.Drew

SQL Server 2005 - ROWVERSION With Datatype Timestamp

May 28, 2008



Hi,
i wanted to read some datasets from a table with the ROWVERSION. Then i wanted to save these records with the ROWVERION- Column in a temp table. Now it seems i cant explicitely write data in a ROWVERSION Column. As i understand its only possible to write a default value in such columns. Only SQL Server itself can write into ROWVERSION columns.

Am i right with this meaning?
Thx in advance...

Converting Timestamp To Varchar Or Concatenating It With A String

Sep 20, 2007

Hello,

I apologise if this question has been asked before but I have searched forums and the web and have not found a solution. I am current creating a script that has a cursor that builds a sql statement to be executed e.g.

--code within cursor

SELECT '
DECLARE @Result INT
EXEC @Result = DELETE_DOCUMENT
@DocumentID = ' + STR(DocumentID) + ',
@TimeStamp =' + CAST([Timestamp] as varchar) + ',

-- CHECK RESULT AND STATUS
-- IF OK LOG IN META_BATCH ELSE LOG ERROR' AS SQL
FROM Document



The problem I am having is trying to join the timestamp column into the sql string. I have tried to cast the time stamp to a varchar but I end up with the following output for the timestamp column values

T
T€‘
T­
xnÞ
T!
T"
T#
T$
T%
T&
T'
T(
T)
T*
T+
T,

instead of


0x0000000013540F1C
0x0000000013540F1E
0x0000000013540F1F
0x0000000013786EDE
0x0000000013540F21
0x0000000013540F22
0x0000000013540F23
0x0000000013540F24
0x0000000013540F25
0x0000000013540F26
0x0000000013540F27
0x0000000013540F28
0x0000000013540F29
0x0000000013540F2A
0x0000000013540F2B
0x0000000013540F2C


which would not allow my delete script to work correctly. So I would really appreciate some advice to a pointer to where I might find out how to convert the timestamp.

Thanks
Sam

Convert Date Time(string Format) To Database Timestamp

Apr 3, 2008

I have two fields DSRHADTI which is an isodate and DSRHTIME which is 8 char time field in format 10.31.00. I want to take both these fields and put them into a field that is database timestamp so I have converted DSRHDATI to 10 character field. I am then trying to use substring to put both into 18 character field using derived column transformation editor. but it does not like the below. It's red syntax error what am I missing.

(SUBSTRING(Copy of DSRHDATI,1,4) +' /' + SUBSTRING( Copy of DSRHDATI,6,2) + '/ ' + SUBSTRING(Copy of DSRHDATI,9,2)) + SUBSTRING(DSRHTIME,1,2) + '.' + SUBSTRING(DSRHTIME,4,2) + '.' + SUBSTRING(DSRHTIME,7,2)

One I get the above to work I plan on convert 18 char to datetimestamp.

Am I on the right track on how to do this?

Active Rowversion Function

Feb 6, 2008

In SQL 2005 I use this 'min_active_rowversion()' to return the lowest active rowversion but this function is not available in SQL 2000. Is there any similar kind of thing in SQL 2000. We have 2 different application one on SQL 2005 and other on SQL 2000.


Thanks !

Rowversion Output Parameter

Sep 14, 2007

Is there an equalivent to scope_identity that supports getting the rowversion value last provided by the system?



The reason I'm asking: We're updating a table, and I want to send the rowversion value back to the client as an output paramter so they can update again without running into a false positive concurrency error.



Without something like scope_identity, I have to run a select statement after the update just to get the rowversion that was provided by the system, and that hardly seems efficient.



My goal is to avoid the extra code and the select statement.

Error While Converting Oracle Timestamp To Sql Server Timestamp (datetime) - Invalid Date Format

Jun 19, 2007

I am populating oracle source in Sql Server Destination. after few rows it fails it displays this error:

[OLE DB Destination [16]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80004005 Description:
"Invalid date format".



I used this script component using the following code in between the adapters, However after 9,500 rows it failed again giving the same above error:








To convert Oracle timestamp to Sql Server timestamp

If Row.CALCULATEDETADATECUST_IsNull = False Then

If IsDate(DateSerial(Row.CALCULATEDETADATECUST.Year, Row.CALCULATEDETADATECUST.Month, Row.CALCULATEDETADATECUST.Day)) Then

dt = Row.CALCULATEDETADATECUST

Row.CALCULATEDETADATECUSTD = dt

End If

End If



I don't know if my code is right . Please inform, how i can achieve this.

Query RowVersion In SQL Server 2005

Feb 6, 2007

Hello all,I am new at SQL Server 2005 and have been reading everything I canfindabout the new optimistic concurrency control mechanisms. As far as Ican tell, the Snapshot Isolation Level is based avoids the use ofshared locks using rowversioning instead.To control rowversions in SQL Server 2000 I was using an extra columnin each table containing a rowversion datatype. What i do with this isfind out if a row was modified. Is it possible in SQL Server 2005 toavoid the use of this extra column, using the new versioning features?What I mean is, if the Snapshot Isolation already manages rowversionsin TempDB, is it possible for me to query those versions using somestored procedures or functions given by SQL Server 2005 system? Whatfunctionalities does SQL Server 2005 gives me for that (anydocumentation pointer would help)?This would allow me to do the exact same processing that i was doingwith the rowversion column in SQL Server 2000 without the need forthat extra column.For all of you my thanks and best wishesSusana Guedes

Get Row Timestamp With No Timestamp Column

Jul 10, 2007

For starters, please feel free to move this if it is in the wrong forum.



The issue I have is this. I have been asked to delete all information from a table that was inserted before May 12 this year. The issue is that when the DB was created, whoever designedd it neglected to add a timestamp column for the user data table (the one I need to purge). Does SQL, by default, happen to store insert times? Would it be something that might hide ina log file somewhere?

hello I put a time stamp in one of my column and it says binary data in the field. How do i make that binary data turn into a real date and time. If this is possible how do I separate the date from the time in the results or would I have to do this myself. Also, I need to sort the results by date can this be done?

Sorry for the stupid questions my sql book (sql demystified) does not elaborate. Thanks

Timestamp

Nov 29, 2007

Hi there,



When inserting into a table with a timestamp column without explicitly setting the column_list you get the following.

ie.



insert into Table_A

select *

from Table_B



Cannot insert a non-null value into a timestamp column. Use INSERT with a column list or with a default of NULL for the timestamp column.



I was wondering if there's a way to overcome this without specifying the column list?



Thanks.

SQLDataSource And Timestamp

Apr 29, 2008

Hi folks, I am binding a gridview to a SQLDataSource that contains a timestamp column. My SQLDatasource contains an update method (via a stored procedure) that takes all of the data fields from the grid as input parameters.  I am getting an error stating 'sql_variant is incompatible with timestamp' .  The parameter definition for the update method specifies the timestamp column as type 'Object'.         <UpdateParameters>             <asp:Parameter Name="timestamp" Type="Object" />            ...        </UpdateParameters> When the data is initially retrieved, the timestamp column is converted to a System.Byte[] however I cannot specify System.Byte[] in the parameter definition (different error) I have read other post with this issue but none seemed to have been solved (while still using SQLDataSource and binding).I have tried other datatypes and they do not work as well. Any help would be greatly appreciatedThanksTom

Using Timestamp With ASP.net / SQL Server

Sep 10, 2004

I have a database that I don't want to lock. I decided that before any updates can occur I would check a timestamp value and ensure that nobody else updated before I did (avoiding the 'last update wins' scenario).

I have a problem, I can read the Timestamp from the db when I read the record. I currently use the data to pre-fill a form (gee go figure ;) ) and the user changes some values and updates.

I don't know what to DO with the timestamp value while I am holding it. I have tried putting it into a hidden field on the form but the value does not seem to translate back and forth.

Do I have to store it as in memory as part of the session or can I somehow convert to and from text??

I have about 0 experience working with byte arrays so the best answer is one with an example.

Thanks.
