SQL Server查询的性能调优

Question

我收到一些错误:

消息205,级别16,状态1,过程SearchUserswithLevels,第29行
所有使用UNION,INTERSECT或EXCEPT运算符组合的查询在其目标列表中必须具有相同数量的表达式.

我附加我的表和存储过程

CREATE TABLE [dbo].[Users]
(
    [Login_ID] [bigint] IDENTITY(1,1) NOT NULL,
    [Login_Name] [nvarchar](100) NOT NULL,
    [Login_Password] [nvarchar](100) NULL,
    [CreatedBy] [bigint] NULL,
    [ModifiedBy] [bigint] NULL,
    [Referal_ID] [bigint] NULL,
    [Name] [nvarchar](250) NULL,
    [User_Address] [nvarchar](max) NULL,
    [Phone] [nvarchar](14) NULL,
    [Email] [nvarchar](250) NULL,
    [BankName] [nvarchar](250) NULL,
    [AccountName] [nvarchar](250) NULL,
    [IFSC] [nvarchar](250) NULL,
    [AccountNo] [nvarchar](250) NULL,
    [DOB] [datetime] NULL,
    [Created_Date] [datetime] NULL,
    [Modified_Date] [datetime] NULL,
    [Last_Login_Date_Time] [datetime] NULL,
    [UnsuscribeEmail] [int] NULL,
    [UnsuscribeSms] [int] NULL,
    [IsBanned] [int] NULL,
    [ISDeleted] [int] NULL,
    [Roles] [nvarchar](max) NULL,
    [IDPROF] [nvarchar](250) NULL,
    [IDPROFNO] [nvarchar](250) NULL,
    [PANCARDNO] [nvarchar](250) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

我的存储过程是这样的:

Answer 1

之后UNION ALL有这样的:

Parent.Login_ID
User_Address,

由Sql Server解释为

Parent.Login_ID AS User_Address,

这使得它成为1场,而不是你想要的2场.添加一个逗号即可完成.
