Hi,
I am reading information of timestamp type in sql server.
I have read something about timestamp is deprecated and new type is rowversion, but in my sql server 2005 there isnt any type rowversion.
is timestamp deprecated?
how can I cast timestampt to datetime?
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
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
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.
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.
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.
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.
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
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, m new to sql server.can any one tell me is it possible to insert only time value in timestamp datatype. i have table which have datatype datetime.and i have to insert only time.i can't change the datatype datetime to any other one.p plz any one can suggest me the solution..
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. The problem is that i need this variable not in bd conotation (like 2007-02-12 12:00:44:33) but like this 2007021212004433. Can someone help me? Thanks in advance.
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 every one I have a timestamp column in my database. I want to use this column to get current changes but i am not able to get desired results when i use to compare that field in C#. Thanks in advance Take Care ALLAH HAFIZ
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.
Actually 'TIMESTAMP' is used to monitor the INSERTION AND UPDATION on a table.Based on that 'TIMESTAMP', is it possible to extract any details by appling some QUERY in QUERY ANALYZER?. If anybody gives a solution to this I will be thankful to them.
