Suppose I have an ADO.NET DataTable that I was to ‘persist’ by saving it

  • 0

Suppose I have an ADO.NET DataTable that I was to ‘persist’ by saving it to a new table in a SQL Server database – is there a fast way of doing this?

I realise I could write code generating the DDL for the ‘CREATE TABLE’ statement by looping through the DataColumns collection and working out the right type mappings and so on … but I’m wondering if there is an existing method to do this, or a framework someone has written?

(NB: I need to be able to handle arbitrary columns, nothing too fancy like blobs; just common column types like strings, numbers, guids and dates. The program won’t know what the columns in the DataTable are until run-time so they can’t be hard-coded.)

    ADO.net cannot create tables in SQL Server directly, however, SMO can do this with the .Create method of the Table class. Unfortunately, there is no built-in way to use a DataTable to define an SMO Table object.

    Fortunately, Nick Tompson wrote just such a DataTable-to-SMO.Table routine back in 2006. It is posted as one of the replies to this MSDN forums topic http://social.msdn.microsoft.com/forums/en-US/adodotnetdataproviders/thread/4929a0a8-0137-45f6-86e8-d11e220048c3/ (edit: I can make hyperlinks now).

    Note also, the reply post that shows how to add SQLBulkCopy to it.
