MYSQL：查询结合计数

Question

sql：

SELECT 
id, COUNT(id) AS Counter
FROM tableA  
GROUP BY id

结果：

目标是如下所示：

将（NULL ID）与ID = 09结合起来，使其为0 + 1 = 1，给id正确命名也很好，比如

ID             Counter
NULLWITH09        1
THE 01           467
THE 02            8

任何帮助都会很棒..谢谢

未经测试，但是这样：

SELECT 
'THE ' +id, COUNT(id) AS Counter
FROM tableA
where id is not null and id<>9  
GROUP BY id
UNION ALL
SELECT 
'null and 9', COUNT(*) AS Counter
FROM tableA
where id is null or id=9
