how to implement restartability in individual mappings of SSIS packages?

restartability, is there any other tool option? like informatica

or

whether we have to implement through hand written query.

if query, then tell me how to do by taking scenarios like loading data from source sql table to target table.

suppose, in my target table, i have to load 100 records.

After loading 10 records,due to database downtime,or failure,

the loading stopped.

Either i have to truncate table or load it from 11th record.

Can u give me how to do this inside mapping

1)for table truncation

2) loading it from 11 th record.

1. Another option instead of table truncation is to use transactions if your database supports it. If something goes wrong, the transaction can be rolled back. Look in Books Online on how to set up transactions with SSIS.

2. There is currently no built-in mechanism in the data flow for restartability at a certain row, so you will need to put something together on your own. For example, have a incrementing key in the source table that you can use to track the rows inserted in the destination. Then, when something goes wrong, modify your source query to return only the rows that haven't been inserted yet.
