MSDE Timestamp Update
Mar 15, 2004
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

Hello readers,
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.
Thanking in advance for your time to read this.
Regards - H C.

The Folowing code is not working anymore. (500 error)
Set objRS = strSQL1.Execute
strSQL1 = "SELECT * FROM BannerRotor where BannerID=" & cstr(BannerID)
objRS.Open strSQL1, objConn , 2 , 3 , adCmdText
If not (objRS.BOF and objRS.EOF) Then
objRS.Fields("Exposures").Value =objRS.Fields("Exposures").Value + 1
objRS.update
End If
objRS.Close
The .execute Method works fine
strSQL1 = "UPDATE BannerRotor SET Exposures=Exposures+1 WHERE BannerID=" & cstr(BannerID)
objConn.Execute strSQL1
W2003 + IIS6.0
Pls advice?

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?

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?

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 have 2 tables, table A and B. Table A has the following fields; Phone (nvchar), Fname (nvchar), Lname (nvchar), DNC (bit). Table B has one field, PhoneNo (nvchar). I would like to update the field DNC in Table A to True(1) if the values Phone in Table A = PhoneNo in Table B.
I tried this syntax but it never updated:
UPDATE dbo.A
SET DNC = 1
WHERE (Phone = 'SELECT MAX dbo.B.PhoneNo FROM dbo.B')
These tables have over 100K records and I would like to make sure it runs through and checks every single record and not just the first 10000.

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'm not sure if it's the setup I did wrong, but I can't seem to get my
text datatype in my database to store more than 900 characters.
I'm trying to setup a news database for my website, which will populate
the information into a datagrid. To test, I manually added a news
item in the database through the visual studio 2003 gui. I
immediately noticed a problem as the I was getting an error after a
long news item saying:
"The value you entered is not consistent with the data type or length of the column, or over grid buffer limit."
I couldn't find anthing to set the buffer limit and the datatype is
"text" filled with simple text in the column. As a further test,
I
simply entered 12334567890123... up to 900 characters and still
recevied the error.
I would appreciate someone leading me in the right direction on this one.
Thanks a lot.

I am trying to change the computer name of a machine running MSDE but I get an error when SQL Server starts. With regular SQL when I change the name of a computer I re-run setup and setup fixes this problem. MSDE can only be installed from unattended mode so I can’t rerun setup and fix the problem.
My question is "How do I change the name of a computer running MSDE with out reinstalling MSDE"

We currently have the problem, that all our machines are produced with the
same name and afterwards the name is changed. So we have the problem that
the checksum key for the MSDE isn't valid anymore. As MSDE can only be installed
from unattended mode so I can’t rerun setup and fix the problem. Does anyone
know a solution for this problem ?? A program recalculating the cheksum ??
regards,
Manfred

I'm not sure if this is the correct forum for this this question but I'll give it a shot.
The only db development that I have ever done is in MS Access. I have a project at work that is being accomplished in VB and I need a db engine to use as the back end. Visual studio came with a copy of MSDE. Is this tool worth using or should I invest in mySQL? Are there any advantages to using MSDE over mySQL?

Hello,
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.

How can I add a timestamp column to a table that will let me know when
a record was inserted? (perhaps by setting a default to that column?)
For some reason, @@currenttimestamp gives me
some binary garbage.
Please help with any suggestions.

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

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

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.

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.
Thanks.
