Anyone know how get all counts in one sql query and really it?

Answer 1

SELECT count(*) as total_count,
       sum(status = 'open') as status_open_count,
       sum(status = 'close') as status_close_count,
       sum(status = 'pause') as status_pause_count
FROM TABLE

使用以下查询：

SELECT status, count(name) as cnt FROM TABLE GROUP BY status;

你可以试试

Select Count(Status),Status,(Select Count(Status) as TotalCount From TABLE) From TABLE Group By Status;

另一种选择：-

SELECT status, COUNT(*) as aCount,
FROM TABLE
GROUP BY status
UNION ALL 
SELECT 'All', COUNT(*) as aCount,
FROM TABLE
