私があなたのニーズを正しく理解していて、テーブルにまったく同じ範囲があるかどうかを確認する必要がある場合は、これを試すことができます

USE [BookingDB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[FindConflict]    
    @FromDate datetime,
    @ToDate datetime,
    @IsConflict bit OUT
AS
BEGIN
    if exists (select * from <your table> where FromDate = @FromDate and ToDate = @ToDate)
        set @IsConflict = 1   
    else
        set @IsConflict = 0
END

重複する範囲について知りたい場合は更新してください、これを試してください

 ...
    if exists (select * from <your table> where FromDate <= @ToDate and ToDate >= @FromDate)
        set @IsConflict = 1   
    else
        set @IsConflict = 0
 ...
