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

Although it doesn't directly address my initial query, I wanted to share a fantastic method I just discovered that enables me to control what the alias would be in SQL Server.

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

I can now do mass insert and update operations by fusing this little slice of SQL with my very sophisticated IQueryable. like 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 need to provide the query's parameters, which you can do by using the guidance provided in the example on my prior question. How can I get an Entity Framework query's parameters?
