Archiving Data From Some Tables - Timestamp Data Type?
Aug 21, 2015
I'm working on archiving data from some tables. I've duplicated the data structure, with the exception of not including the IDENTITY specifier on INT columns, so that the archive table will keep the value that was generated in the original table. This is all going well, until I tried to copy the data over where the column is specified as a timestamp data type. I've looked this up and found a couple of things. First, documentation for SQL 2000 says,
Timestamp is a data type that exposes automatically generated binary numbers, which are guaranteed to be unique within a database. Timestamp is used typically as a mechanism for version-stamping table rows. The storage size is 8 bytes.
And then documentation for the soon to be released SQL 2016 on the rowversion data type says,
The timestamp syntax is deprecated. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
and
Is a data type that exposes automatically generated, unique binary numbers within a database. rowversion is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The rowversion data type is just an incrementing number and does not preserve a date or a time.
OK, I've read the descriptions, but I don't get it. Why have a timestamp/rowversion data type?

Hi,
--sql server 2000
I have a table that has say 100 rows and 4 columns, 4th
one being datatype timestamp.
when a row is inserted the timestamp column also has a
value inserted.My understanding is that whenever the row
is updated(say any of the other three column values are
updated)the timestamp value also changes.
My question is suppose the same row is updated thrice at 3
different times.Will the timestamp VALUE after the last
update guarenteedly be greater than the ones for the early
2 updates..Eg
End of Update1 :Value1(timestamp)
End of Update2 :Value2(timestamp)
End of Update3 :Value3(timestamp)
Does sql server guarantee that Value3>Value2>Value1 ???
If this is true can I use this in any business logic?
Any help highly appreciated !
TIA
Kinnu

HiI'm interested in using the timestamp data type & I have some questions.As far as I can understand the contant of a timestamp column is a binaryvalue.Is there any connection between that value and a valid date (as the wordtimestamp means) or is it a left over from the days when the timestampvalue really was a datetime type (so it says in Books Online) ?or is it just a unique identification of a row (a tuple id) ?I tried converting a timestamp value to datetime and I got a date in 1900.Thanks for any answerDavid Greenberg

Can anyone give me a brief summary of this datatype? Anything that I would need to know to use this in tables that are populated via an asp web service.
Thanks!

I am beginner in SQL Server and this is the first time I tried to use a column in my table with Timestamp data type. When I open my table and enter data in its fields, the timestamp column shows me <binary Data> instead of showing be the timestamp value. I expected to see a kind of hexadecimal number instead. Is it normal? and if yes, How I will be able to display the value of the timestamp.

After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.
anyone having this problem before?? hopefully you guys can help.
Thanks,

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error.

Hi everyone!
My problem is, that i don#t know how i can archive the data. That means to documentate when, who, etc. changed the data (in a seperate table).
I tried to solve it with different triggers.
Thanks in advance,

I need to alter datatypes from
numeric(18,0) to 'int' type across all the tables in the database of about 200 tables. Nearly 200 PK/FKs will be affected with this change..How can I do this with a script? Can anyone help witha script which drops all the constraints/indexs etc and then alters the datatype before re-creating the constraints/indexs..?
P.s. No rounding problem is expected as data is already in whole numbers.
Thanks,
Di.

Hi.
I have tables (they are empty and there are no constraints) with columns typed as varchar. In a database I want to change the type of all the varchar columns in all the tables from varchar to nvarchar. What's the best way to do it? Can you suggest code?
I know that to get all the relevant columns I would issue a query like this
select *
from information_schema.columns
where data_type = 'varchar'
Then I would use a cursor... And that's exactly what I would not like to do. Is there any other way?
Thanx.

Hi,
I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:
this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);
this.mycourtsDataSet1.AcceptChanges();
this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);
This did not happen with VS2005/CE3.01.
I have tried changing all references to decimal (or money in CE3.5) without luck.
I'm beginning to think that string may be the way to go!!!!!!!
Can someone shed some light on my problem.
Thanks,
Later:
It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.

We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.
I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.
On Error, If I fail the component, then the error is :
There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

Hello.
i have a database with 300 tables. All the data types of the fields of my tables are custom. Ex. IFGint:int and stuff like that.
I want to know how can i through a stored procedure, change in batch mode all the fields of my tables. I don't want to modify by hand everytable. It's a lot of work and i think that maybe there might be a way for this programatically.
thanks in advance

Regarding SQL Server data, I am looking to implement the beset Data-Archive and Purge policy. Normal, we do SQL Backups and keep the history for some period , for example, 8 weeks, so we can go back and restore any data point in time upto 8 month in past. and we also do Tape backups.
Question is Where can I get nice article or documentation on this to best design such policy where I make sure that I am covered for point in time recovery of database (which is sql backups) and point in time recovery in far past, say, 3 years ago using tape backups, and I need to make sure that I don't repeat the same efforsts.
Any advices or suggestion on this topic.

Is there a way, for example to script a DTS Package, so that it can be deleted and recreated at a later date if necessary? I have quiet alot of these, but few are used regularly. The msdb database is now up to 80 MB. However I don't want to delete them and have no way to recreate them.If I took a backup of msdb and then deleted the packages, would restoring msdb at a later date restore the packages?????

Hello,
I have been placed in the position of administering our SQL server 6.5 (Microsoft). Being new to SQL and having some knowledge of databases (used to use Foxpro 2.6 for...DOS!) I am faced with an ever increasing table of incoming call information from our Ascend MAX RAS equipment. This table increases by 900,000 records a month. The previous administrator (no longer available) was using a Visual Foxpro 5 application to archive and remove the data older than 60 days. Unfortunately he left and took with him Visual Fox and all of his project files.
My question is this: Is there an easy way to archive then remove the data older than 60 days from the table? I would like to archive it to a tape drive. We need to maintain this archive for the purposes of searching back through customer calls for IP addresses on certain dates and times. We are an ISP, and occasionally need to give this information to law enforcement agencies. So we cannot just delete it.
Sorry this is so long...
Thanks,

Hi folks,
Table:
a int,
b int,
c int,
d text
I need to change my AFTER - Trigger from this (example!):
select * into #ins from inserted
to something like
select *(without Text / nText / image -columns) into #ins from inserted.
So I tried to build a string like this: (using INFORMATIONSCHEMES)
select @sql = 'select a,b,c into #ins from inserted'
exec(@sql)
a,b,c are not of Text, nText or Image datatype.
After executing the trigger, I get an error, that inserted is unknown.
Does anyone know how to solve this ?
Thx.

I have a field that is currently stored as the data type nvarchar(10), and all of the data in this field is in the format mm/dd/yyyy or NULL. I want to convert this field to the smalldatetime data type. Is this possible?
I've tried to use cast in the following way, (rsbirthday is the field name, panelists is the table), but to no avail.
SELECT rsbirthday CAST(rsbirthday AS smalldatetime)
FROM panelists
the error returned is "incorrect syntax near 'rsbirthday'.
I'm rather new to all things SQL, so I only have the vaguest idea of what I'm actually doing.
Thanks for the help!

I am using Visual Studio 2005 and SQL Express 2005. The database was converted from MS Access 2003 to SQL Express by using the upsize wizard.
I would like to store the current date & time in a column in a table. This column is a smalldatetime column called 'lastlogin'.
The code I'm using is:
Dim sqlcommand As New SqlCommand _
("UPDATE tableXYZ SET Loggedin = 'True', LastLogin = GetDate() WHERE employeeID = '" & intEmployeeID.ToString & "'", conn)
Try
conn.Open()
sqlcommand.ExecuteNonQuery()
conn.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
This code works fine on my local machine and local SQL server. However at the client side this code results in the error as mentioned in the subject of this thread. I first used 'datetime.now' instead of 'getdate()', but that caused the same error. Then I changed the code to 'getdate()', but the error still remains.
The server at the client is running Windows Server 2000 UK . My local machiine is running WIndows XP Dutch.
Maybe the conversion from Dutch to UK has something to do with it. But this should be solved by using the 'Getdate()' function..... ?
