I have suddenly faced a problem with moving some records in a SQL Server database from one table to another, using LINQ to SQL. Is it possible to write in LINQ to SQL a query just as simple as this:
INSERT INTO Table2 SELECT * FROM Table1 WHERE Selected = 1
GO
DELETE FROM Table1 WHERE Selected = 1
GO
without using loops and collections?
You absolutely don’t need LINQ here. Consider performance & maintainability implications of issuing two SQL statements (or invoking a sproc) versus having to load potentially thousands of objects and then saving them back again.
Resort to
SqlCommands. That will be your best choice.
