我在MS SQL SERVER的数据库中拥有3个不同的表。

1. LAB_patientreg
2. Patient_master
3. Patient_address

该 LAB Patientreg_ 和 Patient_master 是两个包含患者详细信息的表（两个表中的患者都不相同， LAB
Patientreg_ 是与直接在实验室中注册的患者有关的表，而 Patient_master 是关于在 门诊 或接待时 在 医院中注册的
患者 的表）和 patient_address 是包含在表中登记的患者的地址表 patient_master 。

在某些情况下，我需要所有患者的数据，包括 LAB Patientreg_ 和 Patient_master 以及 Patient_address
。我的目的是创建一个将表中所有值放在一起的视图（即，如果 Patient_master 有50行，而 LAB Patientreg_
有32行，则结果视图应为82行），并且列的数量和类型也仅限于 LAB Patientreg_
但它不起作用，是否可以像我说的那样创建视图？如果不是，我应该怎么做才能获得这种观点？在此先感谢您的帮助。

表的结构如下，

Patient_master

CREATE TABLE [dbo].[patient_master](
    [pid] [int] IDENTITY(1,1) NOT NULL,
    [date_created] [date] NULL,
    [title] [varchar](25) NULL,
    [fname] [varchar](255) NULL,

    [lname] [varchar](255) NULL,
    [addr_id] [int] NULL,
    [sex] [char](1) NULL,
    [dob] [date] NULL,
    [dobType] [tinyint] NULL,
    [marital_status] [int] NULL,
    [religion] [int] NULL,
    [caste] [int] NULL,
    [aadhar_no] [varchar](16) NULL,
    [mother_name] [varchar](100) NULL,
    [guardian_name] [varchar](100) NULL,

    [created_by] [varchar](100) NULL,
    [changed_by] [varchar](100) NULL,

    [voided] [tinyint] NULL,
    [voided_by] [varchar](100) NULL,
    [date_voided] [datetime] NULL,
    [void_reason] [varchar](255) NULL,
    [block] [tinyint] NULL,
    [aliasname] [varchar](50) NULL,
    [confidential] [int] NULL,
    [hospno] [char](8) NULL, PRIMARY KEY(pid)
);

Patient_address

CREATE TABLE [dbo].[patient_address](
    [pres_house_no] [varchar](25) NULL,
    [pres_city] [varchar](50) NULL,
    [pres_street] [varchar](50) NULL,

    [perm_street] [varchar](50) NULL,
    [perm_district] [int] NULL,
    [perm_pincode] [varchar](10) NULL,
    [home_phone] [varchar](11) NULL,
    [mobile_phone] [varchar](11) NULL,
    [other_phone] [varchar](11) NULL,
    [work_phone] [varchar](11) NULL,
    [email] [varchar](255) NULL,
    [emerg_cntct] [varchar](50) NULL,
    [emerg_cntct_rltn] [varchar](50) NULL,
    [emerg_cntct_num] [varchar](11) NULL,
    [pres_place] [varchar](255) NULL,
    [perm_place] [varchar](255) NULL,
    [addr_id] [int] IDENTITY(1,1) NOT NULL,
    [pid] [int] NULL,
    [active] [char](1) NULL,
    [phone_type] [varchar](4) NULL, , PRIMARY KEY(addr_id)
);

LAB_patientreg

CREATE TABLE [dbo].[LAB_patientreg](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [patientid] [varchar](15) NOT NULL,
    [title] [varchar](15) NULL,
    [fname] [varchar](50) NULL,
    [mname] [varchar](50) NULL,
    [lname] [varchar](50) NULL,
    [dob] [smalldatetime] NULL,
    [gender] [char](2) NULL,
    [mstatus] [varchar](15) NULL,
    [idtype] [varchar](15) NULL,
    [idno] [varchar](25) NULL,
    [mtongue] [varchar](35) NULL,
    [address] [varchar](300) NULL,
    [phtype] [varchar](15) NULL,
    [phno] [varchar](20) NULL,
    [emailid] [varchar](50) NULL,
    [smsstatus] [int] NULL,
    [mailstatus] [int] NULL,
    [status] [int] NULL,
    [regcenter] [varchar](30) NULL,
    [regdate] [smalldatetime] NULL, PRIMARY KEY(patientid)
);

我尝试了以下

Select patientid,title, fname, mname, lname, NULL As religion from LAB_patientreg WHERE 1=1
Union All  
Select pid,title, fname, mname, lname, religion from patient 
INNER JOIN patient_address ON patient.pid = patient_address.pid WHERE 1=1

执行此操作时，将发生错误，错误代码为209，SQL状态为S1000：列名“ pid”不明确”
