如何在SQL Server 2005中的值中使用插入查询内的选择查询

Question

insert into patient_record(patient_no, patient_name, datetime_of_birth, 
                           GP_unique_no, GP_name, GP_address,complaint,
                           treatment, doctor, datetime_treatment_started, 
                           datetime_treatment_ended)

values(13, 'Sophie', '1955-05-13', 'G202',
       **select name_of_doctor from gp_doctor where unique_no=G202**,
       'Yorkshire', 'Broken right arm', 'Plaster Arm', 'Peter Parker',
       '2012-01-25','2012-01-29')

我不知道如何添加G202.任何的想法？

Answer 1

你不能在INSERT声明中间进行子选择....你需要在运行之前执行此操作INSERT:

DECLARE @GPName VARCHAR(100)

SELECT @GPName = name_of_doctor 
FROM dbo.gp_doctor 
WHERE unique_no = 'G202'  -- I assume this is really a *string* here for the "unique_no"

INSERT INTO 
   dbo.patient_record(patient_no, patient_name, datetime_of_birth, 
                      GP_unique_no, GP_name, GP_address, complaint,
                      treatment, doctor, datetime_treatment_started, 
                      datetime_treatment_ended)
VALUES
     (13, 'Sophie', '1955-05-13', 
      'G202', @GPName, 'Yorkshire', 'Broken right arm', 
      'Plaster Arm', 'Peter Parker', '2012-01-25','2012-01-29')

或类似的东西.

Answer 2

假设unique_no是唯一的,您可以选择该记录来获取名称

insert into patient_record(patient_no, patient_name, datetime_of_birth, 
                           GP_unique_no, GP_name, GP_address,complaint,
                           treatment, doctor, datetime_treatment_started, 
                           datetime_treatment_ended)

SELECT
   13, 
   'Sophie', 
   '1955-05-13', 
   'G202',
    name_of_doctor,
    'Yorkshire', 
    'Broken right arm', 
    'Plaster Arm', 
    'Peter Parker',
    '2012-01-25','2012-01-29'
FROM gp_doctor 
where unique_no = 'G202'
