Timestamp To Datetime Conversion In Primary Key
Jul 10, 2006
Hi,
I'm trying to persist a field of type java.sql.Timestamp to a column of type datetime in sql server 2005. I get an exception :
java.lang.UnsupportedOperationException: cannot perform lookups on timestamps. The field i'm trying to persist is a part of a composite primary key. The detailed exception is as follows:
12:13:55,110 WARN [RequestProcessor] Unhandled Exception thrown: class java.lang.UnsupportedOperationException
12:13:55,110 WARN [RequestProcessor] Unhandled Exception thrown: class java.lang.UnsupportedOperationException

I have tried these with my other tables and never got an exception. but this is the first time i'm trying timestamp to datetime conversion with a primary key.
Can anyone suggest what could be the reason?
Thanks, Nithya.

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'm having trouble converting a timestamp value passed into a stored procedure as a char to binary(8). For example, the value passed in is
'00000000000002CA'. I want to convert to a binary(8) value so I can use this in the where clause of a query.
I can't seem to get the conversion to work correctly.
Thanks in advance for your help.

i have following problem. i'v designed a package which works pretty fine but now i discovered that i have performance troubles when trying to convert timestamps. I have a generated Timestamp [DT_DBTIMESTAMP], but i transfer the data to an AS/400 where i need the timestamp in the format "2008-03-12-13.37.32.000000". so i've used a derived column component with following conversion
REPLACE(REPLACE((DT_WSTR,50)ZEITPUNKT,":",".")," ","-") + ".000000"
is there a more performant way to do this? Because this makes the whole package really slow.
thx

Hi everyone!I've read a lot of document about optimistic concurrency and different implementations which made me decide to chose the timestamp/datetime approuch to validate if another user has editet the record.I'm saying timestamp OR datetime because I dont really care which one to use but I can't make any of them work as expected.Here is my setup:I'm using a DataSet (autogenerated by Visual Studio 2005) with 4 stored procedures to select, update, delete and insert records.I'm using a GridView to show these values but when using a timestamp in the database the parameter type in my ObjectDataSource is an Object which ofcause ins't right and I can't change it to Byte[].If I instead use a Datetime I believe that the date formatting is done somehow (even though i make the field ReadOnly in the GridView) - I can see the date is shown as: "01-01-1900 00:01:07" but the actually SQL that is executed is: 'Jan 1 1900 12:01:07:000AM' why this differense?So my question is which one should I use and how - the datetime/timestamp dosn't have to be shown - I would actually prefer that the datetime/timestamp was somehow hidden from the presentationlayer and only present in the data access layer but still would be transfered to and from the database when doing updates etc.Best of all I could use a working example.Thanks in advance :-)

Is it possible to convert a timestamp value to its associated datetime?
I know that the timestamp is not directly convertable to a datetime but does the database know at what time that timestamp was assigned?

I am using SSIS to move data from SQL Server 2000 to DB2 on the Iseries. I am using DB2OLEDB provider to connect to the DB2 database. The problem I am running into is the DB2 Timestamp format is 'yyyy-mm-dd-hh.mi.ss' and I am unable to get my Date format correct.
Inside SSIS I have created a custom script to and parse the SQL date to this format using a string but I can cast the string back to date format.
Any help would be Great.

I created a SSIS package and creating a derived column named: Date...set datatype as DT_DBDATE....I do not want the timestamp on date...then I want to load this Date into a SQL server database table, with datatype of datetime, but it will load here with the timestamp which I do not want. Any ideas? I did change datatype of the SQL Server Destination datatype to DT_DBDATE but it will change it back to DT_DBTimestamp. thx

In SQL Server I've created a linked server to an Oracle database. I am trying to insert (within the context of an sql server table trigger) an SQL Server datetime to an Oracle column with similar precision. Oracle timestamps are not compatible with sql server datetimes and I don't know how to convert the data (or if I should use a different type of column to store the data in Oracle). I have full control over the structure of the Oracle table so I can use a different type if timestamp is not best, but I need the destination column to have at least the same precision as the sql server datetime value. What is the easiest way to do this?

Hello, I would appreciate any suggestions
I've got a datetime field that I'd like to store as just the date without the time component, but still to keep it defined as a datetime field. I ran this update statement but this conversion isn't working. Conversion to char gives me what I want but I need to keep the field as a date datatype if possible.
Thanks :)
