Error during executing OLEDB command

Hi All,

My requirement is pretty simple. I am doing a lookup if i found some existing data then updating the table else inserting new data to the table.

For updating existing data i am using a 'OLEDB command' transformation and my query is as follows.

UPDATE User_details SET No_of_hours=? WHERE USER_NAME=? AND project_name=? AND week_start_date=?

Properties:

Command timeout: 1000

Default Code page:1252

Validate External meta data: true

For these four parameters i used to map with records from the lookup.

While executing this i am getting a runtime error as below.

[OLE DB Command [1167]] Error: SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80040E37.
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80040E37  Description: "Invalid object name 'tg_DataCleaningMaintenance_PendingInsert__20121120_000000_2d204e60-2bc0-41ef-8f76-ea7ee24a03c9'.".

Any help/suggestion will be highly appreciable..

Thanks,
