How can I get the column aliases generated by Entity Framework?

This doesn't directly answer my original question, but I just learned of an awesome trick that allows me to override what the alias would be (in SQL Server) and I had to share it.

var query = myIQueryable.ToString();
var sql = $@"SELECT x.myAlias
             FROM ({query}) x(myAlias)";

Now I can combine my super-complex IQueryable with this little snippet of SQL to do bulk insert and update operations. Such as:

var query = myIQueryable.ToString();
var sql = $@"INSERT INTO dbo.myTable (col1)
             SELECT x.myAlias
             FROM ({query}) x(myAlias)";

Or

var query = myIQueryable.ToString();
var sql = $@"UPDATE dbo.myTable
             SET Col1 = 1
             FROM dbo.myTable
             JOIN ({query}) x(myAlias) ON x.myAlias = dbo.myTable.SomeColumn";

Of course, you still have to plug in the parameters of the query, which you can get by following the example given on my previous question: How can I get the parameters of an Entity Framework query?
