sql案例----统计某字段中相同值的个数

1、统计某字段中相同的值个数

需求：统计表ZB_XMGSHZ中 F_QK='塔河十区' 和 F_QK='塔河十二区'的个数，返回两个字段

sql：

select sum(f_qkgs1) as f_qkgs3,sum(f_qkgs2) as f_qkgs4 from (select  count(1) as f_qkgs1,0 AS f_qkgs2 FROM ZB_XMGSHZ WHERE F_QK='塔河十区'

UNION all

select  0 as f_qkgs1，count(1) as f_qkgs2 from ZB_XMGSHZ where F_QK='塔河十二区' )
