在sql server中按字符串对列排序？

这是存储错误消息的表

是否可以获取所有错误消息的计数

例如

消息：-“LogsIndex”未被激活。计数=1

---

消息：-“路径的控制器”无效。计数=5请尝试这个答案

LogID   Title   Message
1   Error Occured   Could not find stored procedure 'RT_SELECTAll1_Users'. : [UserID={2}],[UserSessionID={10068}]
2   Error Occured   A public action method 'LogsIndex' was not found on controller 'oMail.Web.Controllers.EmailTemplateController'. : [UserID={2}],[UserSessionID={20071}]
3   Error Occured   The controller for path '/ControllerName/ActionName' was not found or does not implement IController. : [UserID={2}],[UserSessionID={20071}]
4   Error Occured   The controller for path '/ControllerName/ActionName' was not found or does not implement IController. : [UserID={2}],[UserSessionID={20071}]
5   Error Occured   The controller for path '/ControllerName/ActionName' was not found or does not implement IController. : [UserID={2}],[UserSessionID={20071}]
6   Error Occured   The controller for path '/ControllerName/ActionName' was not found or does not implement IController. : [UserID={2}],[UserSessionID={20071}]
7   Error Occured   The controller for path '/ControllerName/ActionName' was not found or does not implement IController. : [UserID={2}],[UserSessionID={20071}]
8   Error Occured   The controller for path '/ControllerName/ActionName' was not found or does not implement IController. : [UserID={2}],[UserSessionID={20071}]

选择消息并执行计数，然后根据消息对结果进行分组，如下所示：

SELECT Message, count(1) as MCount 
FROM TableName

---

由于消息不完全相同，我只能看到您使用LIKE和case：

    Select Message, Count(*) as 'Count'
    From Table
    Group by Message

你可以使用CTE或者一个联合体使它更优雅一些，如果你想简化它的话

您可能希望通过日期或其他方式对此进行限制。

选择消息，从TableName中将（1）计数为MCount

SELECT
    CASE 
        WHEN Message like '%LogsIndex%' THEN 'LogsIndex'
        WHEN Message like 'The controller for path'' was not%' THEN 'Controller Path'
        ELSE 'Other'
    END AS UserMessage
    ,count(*)
FROM
    TableName
Group by
    CASE 
        WHEN Message like '%LogsIndex%' THEN 'LogsIndex'
        WHEN Message like 'The controller for path' was not%' THEN 'Controller Path'
        ELSE 'Other'
    END
