How to count the number of records after MySQL is grouped gourp by ()

Select COUNT (*) from table name where condition//This is the total record bar select COUNT (*) from table name where condition GROUP BY ID//This will count the number of records per group.

How do I get the total number of records for a second SQL statement?

The following is the case:

Select COUNT (*) from (SELECT COUNT (*) from table name WHERE condition GROUP by id) A;

Select COUNT (*) from (SELECT COUNT (*) from ' Papa_stadium_goods_storage_record ' WHERE ' c_time ' >=1474560000 and ' c_time ' <1476201600 GROUP BY ' Record_type ') a

Attention:

Sub-query, the MySQL neutron result set must use aliases, and Oracle does not need to intentionally add aliases!
