如何在唯一选择中获得条目数和列名？

Question

I have the following table:

IdColumn   Name      Role   Status
  1        peter     Ope        0
  2        peter     Adm        1
  3        Jon       Ope        1
  4        Mac       Adm        1
  5        Jon       Adm        0
  6        peter     Sec        1

What I wanted to get is the column name and number of entries for each one in a single query.

select Name, Count(*) from table where Status = 1; 

Exit example:

---------------
Name | Count()|
---------------
peter|  2     |
Jon  |  1     |
Mac  |  1     |
---------------

Answer 1

This is a basic group by query:

select Name, Count(*)
from table
where Status = 1
group by Name;

If you are going to use SQL, you should learn the basics. group by and join are definitely basics of the SQL language.

Answer 2

Use group by clause:

select Name, Count(*) from table where Status = 1 group by Name;

                                             Add group by here
