How to order by an arbitrary condition in SQL

问题:

I have the following table:

CREATE TABLE Bable
    (
     id int identity primary key, 
     name varchar(20), 
     about varchar(30)
    );
INSERT INTO Bable (name,about) VALUES
('ООО Name Firm 1','texttexttexttext'),
('ООО Name Firm 2','texttexttexttext'),
('ООО Name Firm 3','texttexttexttext'),
('ООО Name Firm 4','texttexttexttext'),
('ООО Name Firm 5','texttexttexttext'),
('ООО Name Firm $1','texttexttexttext'),
('ООО Name Firm $2','texttexttexttext'),
('ООО Name Firm $3','texttexttexttext'),
('ООО Name Firm 6','texttexttexttext'),
('ООО Name Firm 7','texttexttexttext')

And I can write a query like the following:

SELECT * FROM Bable WHERE about = 'texttexttexttext'

How can I alter this query to return results ordered such that those with names containing "$" appear first, followed by those that do not, with each group then ordered by name ascending?

Structure of the table is here

          Name

You can do the same with charatindex

SELECT * FROM Bable WHERE about = 'texttexttexttext'
Order by Case When CHARINDEX('$',name)>0 Then 0 Else 1 End,name
