Hi guys

USE [Agency]
GO

/****** Object:  Table [dbo].[productivity_Tb]    Script Date: 10/06/2013 01:17:48 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[productivity_Tb](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Date1] [datetime] NULL,
    [Month1] [int] NULL,
    [Collector] [nvarchar](max) NULL,
    [CM_ID] [int] NULL,
    [ACC_NO] [int] NULL,
    [Balance] [money] NULL,
    [BKT] [nvarchar](255) NULL,
    [Call_Visit] [nvarchar](255) NULL,
    [Trials] [nvarchar](255) NULL,
    [PTP_Type] [nvarchar](255) NULL,
    [PTP_Date] [date] NULL,
    [PTP_Amount] [money] NULL,
    [PTP_Kep_Broken] [nvarchar](255) NULL,
    [Kept_Amount] [money] NULL,
    [feedback] [nvarchar](255) NULL,
    [New_Address] [nvarchar](255) NULL,
    [NEW_MOBIL] [int] NULL,
    [Area] [nvarchar](255) NULL,
    [Officer] [nvarchar](255) NULL,
    [Agency] [nvarchar](255) NULL,
    [situation] [nvarchar](255) NULL,
 CONSTRAINT [PK_productivity_Tb] PRIMARY KEY CLUSTERED
(
    [ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

现在我想在date1 =和date1 =之间得到收集器的数量，但我希望它没有按日期计算重复的收集器订单1



i需要此查询

now i want to get count of Collector between date1 = "" and date1 ="" but i want it to didnot calculate the repeat Collector order by date1

i need this query

推荐答案

select distinct [Collector],count(Collector) as NumberOfCollectors FROM productivity_Tb WHERE Date1 BETWEEN '2013-01-31' AND '2013-08-01' group by [Collector]

尝试：

Try:

SELECT COUNT(*) FROM productivity_Tb WHERE Date1 BETWEEN '2013-01-31' AND '2013-08-01'
