Question

我正在编写高级搜索，但该过程有效但返回所有选定的行并且不执行任何检查。

ALTER proc [dbo].[spSearchpatientinfo]
   @user nvarchar(50),
   @accountstart int,
   @accountend int,
   @mnumber nvarchar(20),
   @namefirst nvarchar(30),
   @namelast nvarchar(100),
   @registrationfrom datetime,
   @registrationto datetime,
   @office nvarchar(1),
   @status nvarchar(1)
as
begin
   select   
      pi_reg_id, pi_first_name, pi_last_name, 
      pi_dob, pi_address, pi_city, pi_phone_home,
      pi_phone_work, pi_Email, pi_status 
   from 
      MData.dbo.[Patient info]
   where 
      (pi_insert_user = @user)
      or (@accountstart IS NULL or pi_reg_id >= @accountstart)
      or (@accountend IS NULL or pi_reg_id <= @accountend)
      or (@mnumber IS NULL or pi_phone_home like @mnumber)
      or (@namefirst is null or pi_first_name like @namefirst)
      or (@namelast is null or pi_last_name like @namelast)
      or (@registrationfrom is null or pi_reg_date >= @registrationfrom)
      or (@registrationto is null or pi_reg_date <= @registrationto)
      or (@office is null or pi_office = @office)
      or (@status is null or pi_status = @status)
end

请告诉我正在做的错误

由于您通过下级或子句检查传入的变量，我不认为您对外部条款的确是OR。

ALTER proc [dbo].[spSearchpatientinfo]
@user nvarchar(50),
@accountstart int,
@accountend int,
@mnumber nvarchar(20),
@namefirst nvarchar(30),
@namelast nvarchar(100),
@registrationfrom datetime,
@registrationto datetime,
@office nvarchar(1),
@status nvarchar(1)
as
begin
select   pi_reg_id,pi_first_name,pi_last_name,pi_dob,pi_address,pi_city,pi_phone_home,pi_phone_work,pi_Email,pi_status from MData.dbo.[Patient info]
where (@user is null or pi_insert_user = @user)
AND (@accountstart IS NULL or pi_reg_id >= @accountstart)
AND (@accountend IS NULL or pi_reg_id <= @accountend)
AND (@mnumber IS NULL or pi_phone_home like @mnumber)
AND (@namefirst is null or pi_first_name like @namefirst)
AND (@namelast is null or pi_last_name like @namelast)
AND (@registrationfrom is null or pi_reg_date >= @registrationfrom)
AND (@registrationto is null or pi_reg_date <= @registrationto)
AND (@office is null or pi_office = @office)
AND (@status is null or pi_status = @status)
end

虽然我发现了一个潜在的问题，但这里的SP是为了给你所寻找的而改写的。在WHERE子句中，“like”是你的参数，附加了“％”？如果没有，他们可能找不到任何东西。

ALTER PROC [Dbo].[Spsearchpatientinfo]
    @user NVARCHAR(50), 
    @accountstart INT, 
    @accountend INT, 
    @mnumber NVARCHAR(20), 
    @namefirst NVARCHAR(30), 
    @namelast NVARCHAR(100), 
    @registrationfrom DATETIME, 
    @registrationto DATETIME, 
    @office NVARCHAR(1), 
    @status NVARCHAR(1)
AS
BEGIN
   SELECT Pi_Reg_Id, 
        Pi_First_Name, 
        Pi_Last_Name, 
        Pi_Dob, 
        Pi_Address, 
        Pi_City, 
        Pi_Phone_Home, 
        Pi_Phone_Work, 
        Pi_Email, 
        Pi_Status
    FROM Mdata.Dbo.[Patient Info]
    WHERE(Pi_Insert_User = @user)
    AND Pi_Reg_Id >= ISNULL(@accountstart, Pi_Reg_Id)
    AND Pi_Reg_Id <= ISNULL(@accountend, Pi_Reg_Id)
    AND Pi_Phone_Home LIKE ISNULL(@mnumber, Pi_Phone_Home)
    AND Pi_First_Name LIKE ISNULL(@namefirst, Pi_First_Name)
    AND Pi_Last_Name LIKE ISNULL(@namelast, Pi_Last_Name)
    AND Pi_Reg_Date >= ISNULL(@registrationfrom, Pi_Reg_Date)
    AND Pi_Reg_Date <= ISNULL(@registrationto, Pi_Reg_Date)
    AND Pi_Office = ISNULL(@office, Pi_Office)
    AND Pi_Status = ISNULL(@status, Pi_Status);
END;
