Answer 1

select count(*) from table1
where status in ('closed,unclosed')
group by status,month(call_time)   

Answer 2

试试这个：

SELECT COUNT(*) FROM <table name> WHERE status="closed"; 


SELECT COUNT(*) FROM <table name> WHERE status="unclosed";

Answer 3

使用YEAR和月份部分使用MONTH函数和表中的status列从日期中获取部分，并将其用作子集，然后使用CASE表达式按年份和月份计算Closed和Unclosed状态组。

<强>查询

SELECT t.`YEAR`, t.`MONTH`,
SUM(CASE t.`status` WHEN 'Closed' THEN 1 ELSE 0 END) AS `Closed`,
SUM(CASE t.`status` WHEN 'Unclosed' THEN 1 ELSE 0 END) AS `UnClosed`
FROM(
    SELECT YEAR(`call_time`) AS `YEAR`,
    MONTH(`call_time`) AS `MONTH`,
    `status`
    FROM `your_table_name`
)t
GROUP BY t.`YEAR`, t.`MONTH`;

您可以尝试以下查询。

SELECT *
FROM 
(
    (
        SELECT MONTH(mt1.calltime) AS MONTH, YEAR(mt1.`calltime`) AS YEAR, COUNT(mt1.`status`) AS closed, 0 AS unclosed
        FROM myTable mt1
        WHERE mt1.`status`='closed'
    )
    UNION ALL
    (
        SELECT MONTH(mt2.calltime) AS MONTH, YEAR(mt2.`calltime`) AS YEAR, 0 AS closed, COUNT(mt2.`status`) AS unclosed
        FROM myTable mt2
        WHERE mt2.`status`='unclosed'
    )
) AS tablea
GROUP BY tablea.month

将myTable替换为您的表名。

MONTH将从指定日期提取一年中的一个月，而YEAR将提供一年。
