entity framework - Is it possible for EF6 migration up command to delete database with these commands? -

  public override zeros () {update} -  
 AddColumn ("dbo.Term", "Term_Id", c = & gt; c.Int ()); Createindex ("dbo.Term", "Term_ID"); AddForeignKey ("dbo.Term", "Term_Id", "dbo.Term", "ID"); }  
 
 -babus generates this ... 
 
  original: configuration). Apply explicit migration: [201410271927053_addTermsTable2] Apply explicit migration: 201410271927053_addTermsTable2Additional terms [DBO]. [Duration] ADD [Term_Id] [ININ] CREATE INDEX [IX_Term_Id] ON [dbo]. [Period] ([Term_Id]) optional table [dbo]. [Period] ADD CONSTRAINT [FK_dbo.Term_dbo. [MRI] [[Migration IID], [referencing], [model], [product]]  
 (Also included in the migration statement)
