通过对SQL查询进行分组检索个人计数

Question

我想检索每个顾问的待处理查询计数和已完成查询的计数，并在表格中显示。什么是SQL查询来检索这些数据？

SELECT CounsellorName, 
    (SELECT COUNT(Status) 
    FROM register WHERE Status='Pending') AS pending, 
    (SELECT COUNT(Status) FROM register WHERE Status='Completed') AS completed 
FROM register 
GROUP BY CounsellorName 

我目前使用这个，但它不检索每个顾问的个人计数。

感谢您的支持！

试试这个：

SELECT CounsellorName, 
    sum(Status='Pending') AS pending, 
    sum(Status='Completed') AS completed 
FROM register 
GROUP BY CounsellorName 

发现未决的数量和每counsellorName完成状态。
