I am using SQL Server 2005. and i use optimistic Concurrency
based on Timestamp column.
After updating a record, the database engine changes the timestamp column's value,
and we normally fill the record again in the application to get the latest Timestamp value.
I want to know the following:
[As in - INSERT we use Scope_Identity() with output parameters
to get the primary key generated by the database]
Similarly is there any function to get the Timestamp generated after the update.
I know there is @@DBTS but this only works for Inserts (for me atleast. may be i am using it wrongly)
If there is any such function or method for this, this will save a roundtrip to the server
saving so many resources.
If anyone can help me on this, it would be realy realy great.
Can any one please tell me how to retrieve values from timestamp column. I am getting 1900-01-01 00:02:09.457. It is not storing current timestamp when record is created or modified.
Hi! How would I go about updating the date in a column with time&date like this "2/2/2003 12:13:45 AM". Is there a easy way to change this on a MSDE dB with a query in Access2000. Could I use a substring function or something?
This is what i've come up with til now: UPDATE table SET tablename.column = '2/29/2003 ' + [somefunc(column,something)] WHERE tablename.column = '3/1/2003 ' + [somefunc(column,something)]
If you have any good Answeers please post them. Thank's
Hi,I'm attempting to update one row using strored procedure which check timestamp field. IF EXISTS (SELECT * FROM sysobjects WHERE type = 'P' AND name = 'tbCharakterystyki_Update')BEGINDROP Procedure tbCharakterystyki_UpdateENDGO CREATE Procedure dbo.tbCharakterystyki_Update@CH_ID int ,@CH_CHARAKTERYSTYKA VARCHAR(30),@CH_OPIS VARCHAR(300),@CH_TIMESTAMP timestampAS UPDATE tbCharakterystyki SET ch_charakterystyka = @CH_CHARAKTERYSTYKA, ch_opis = @CH_OPIS WHERE ch_id = @CH_ID AND ch_timestamp = @CH_TIMESTAMP GO Function which call stored procedure:public int CallSP(DataRow dr) { try { SqlConnection conn = new SqlConnection(this.strConnection); SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = "dbo.tbCharakterystyki_Update"; SqlParameter p1 = new SqlParameter(); p1.ParameterName = "@CH_ID"; p1.SqlDbType = SqlDbType.Int; p1.Value = dr[0]; SqlParameter p2 = new SqlParameter(); p2.ParameterName = "@CH_CHARAKTERYSTYKA"; p2.SqlDbType = SqlDbType.VarChar; p2.Value = dr[1]; SqlParameter p3 = new SqlParameter(); p3.ParameterName = "@CH_OPIS"; p3.SqlDbType = SqlDbType.VarChar; p3.Value = dr[2]; SqlParameter p4 = new SqlParameter(); p4.ParameterName = "@CH_TIMESTAMP"; p4.SqlDbType = SqlDbType.VarChar; p4.Value = dr[3]; cmd.Parameters.Add(p1); cmd.Parameters.Add(p2); cmd.Parameters.Add(p3); cmd.Parameters.Add(p4); cmd.Connection.Open(); cmd.ExecuteNonQuery(); cmd.Connection.Close(); return 0; } catch ( Exception err ) { ShowError(err.Message) return null; } } And function which call "CallSP()":private void Update(){DataSet ds = helper.GiveDataSetCharakterystyki()DataRow dr = ds.Tables[0].Select("ch_id=51")[0]; dr[1] = "new value";CallSP(dr);}When I fire Update(), stored procedure (dbo.tbCharakterystyki_Update) is not started, Sql Profiler doesn't show it.Whilst when I modify stored procedure, removing WHERE ch_id = @CH_ID AND ch_timestamp = @CH_TIMESTAMP and put only WHERE ch_id = @CH_ID , it works perfectly.What I did wrong?
Hi, How can i store the record insert/update timestamp in a SQL server 2000 db programacally. ? what are the date/time functions in ASP.NET 2.0 ? I know that this can be done by setting the default valut to getdate() function in SQL, but any other way on ASP page or code-behind page ???
I know 2008 MS SQL Server has a timestamp data type that adds date and time when the rows are inserted. Is there a way to automatically update the date and time when the rows are updated?
Can anyone help with an effective way in retriving the id of the new record before input of any data into a form. We have a form where a few of the controls recordsource requires the new record id before they will display correctly. I have tried various ways to trigger the form afterupdate event in the hope that the id will be returned but get the error message "The data will be added to the database but the data won't be displayed in the form because it doesn't satisfy the criteria in the underlying recordsource"
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.

I am making a web site in which i need to update a database with certain values which include the current user who invoked the insert command so how to retrieve the current userID
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?
I have a timestamp in a date field of a table I have but when run it does not enter the date automatically and all I get is system.byte[] display where the dtae and time should be, how can i get it so this field places the date in automatically.???
I am retrieving data from a database, and have been noticing some really strange timestamps. Has anyone ever seen a timestamp that looks like this: 16777215Karls
I just started using SQL and i don't really know too much syntax.
I have an ASP page that is inserting data into a table called YellowAlerts. The first field in this table is AlertDate. I thought I read somewhere that there is a timestamp feature. If anyone could help me out that would be great.
I believe that all created tables have got by default a timestamp field. I tried to find out how to read this field with a Transact-SQL statement. And so I don't know the syntax, is anyone can help me ?
If i have a table with a 3 fields and one of them has a timestamp as a field type and I want to do an insert or update what is the value I am inserting for the column timestamp.
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

Hello I'm not a SQL Expert but i'm using it for a few months. Now i need to use a variable that everytime that is called to a select into it gives the timestamp (or Stamp) to put on a specific field.

Is there any reason to have a TimeStamp column onto a table that has aPrimaryKey when using SQL Server and an Access front end?I read that doing so will always eliminate that write conflict error.But I notice that when pulling a recordset of 10K records, it takes 3Xless time if I delete the timestamp column on the table before runningthe SP.lq
Is there any chance to get the content of a timestamp field?I am trying to get the content via Visual Objects and I am receiving onlynothing.Not NIL but "".Is it possible to get any useful information out of this field in anylanguage?(btw I know that the MS-Timestamp is not a timeformat)THXJens

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
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.
Hi world,I would like to know how to maintain a table with a "timestamp" column. I mean a column that automatically set the current datetime when the row is updated.I don't want to go trought my application and set that in the update or insert command. I would like to know if there is a possibility of putting a trigger or something.thx
I have a table in SQL server 6.5 which has two columns. One is a timestamp column and another is an int column. Now I need to change the int column to numeric (16). For this I cannot use the alter table statement as it is not there in sql server 6.5. I tried creating another table with two columns- one as numeric(16) and the other as timestamp. I transferred the data from he old table to the new table and dropped the old table and finally renamed the new table as the name of the old table. But the problem is that the timestamp column now contains data that is different from the data that was there in the original column. I cannot update the timestamp column as that is done automatically neither can I insert the values. How do I make sure that the data in the timestamp column remains the same.
