如何查找重复名称的总数

Question

我有一张桌子

CREATE TABLE [dbo].[tblTeams](
[Id] [int] IDENTITY(1,1) NOT NULL,
[TeamId] [varchar](5) NOT NULL,
[TeamName] [varchar](100) NOT NULL,
[PlayerName] [varchar](100) NOT NULL,
[PlayerNickName] [varchar](100) NULL,
[Status] [int] NULL

现在我写了一个存储过程：

Alter Proc [dbo].[SpGetDuplicateName]
    @PlayerName varchar(200)
AS
Begin
(
    Select PlayerName,TeamName,TeamId 
    from tblTeams where PlayerName like @PlayerName 
)
END

现在我想返回名称被复制的次数

需要帮助

Answer 1

对 Ullas 查询的小改动... HAVING 将只返回骗子

SELECT PlayerName, COUNT(PlayerName) AS [Count]
FROM tblTeams
WHERE PlayerName LIKE '%word_to_search%'
GROUP BY PlayerName;
HAVING COUNT(*)>1

Answer 2

将COUNT 与GROUP BY 一起使用。

查询

SELECT PlayerName, COUNT(PlayerName) AS [Count]
FROM tblTeams
WHERE PlayerName LIKE '%word_to_search%'
GROUP BY PlayerName;
