I am trying to alter a table field – with some rows in it – from DateTime to DateTime2(3).
But the SQL Server Management Studio complains that I have drop and re-create the table.
But why?
Isn’t DateTime2(3) has more precision than DateTime type? It should be fine, should not it be?
There is a setting in SSMS that will allow you to do what you want.. Menu-Tools-Options-Designers-Prevent saving changes that require table re-creaction.
SSMS has a habit of recreating almost any changes you do. It should be just fine to only alter the column data type with something like this.
