SqlCommandBuilder .. The One I Forgot to Complete the Puzzel

Basically:.NET 2.0 is too cool :)))

After exploring the smo classes the last part of the afternoon was about creating migrating the data. I hadn’t used the ado api fully but remembered something about the commandbuilder. My conclusion : Worth taking a look at.

I do realise that it isn’t the worlds prettiest sql that gets generated but it gets the job done.  And in the case of my 125 tables that i need to migrate FAST it will save me about 1-2 weeks of writing import procedures etc. Generic datatable updates by writing one sql select command.

   18  public void ImportData(DataTable dt)

   19         {

   20             System.Text.StringBuilder sb = new StringBuilder();

   21             using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings[“ConnectionString”].ConnectionString))

   22             {

   23                 SqlCommand cmd = new SqlCommand(string.Format(“Select * from {0}”, dt.TableName),conn);

   24                 SqlDataAdapter da = new SqlDataAdapter(cmd);

   25                 SqlCommandBuilder builder = new SqlCommandBuilder(da);

   26                 //da.UpdateBatchSize = 15;

   27                 da.Update(dt);


   29             }

   30         }
