Question

Merge into AyubMedicalHospital.dbo.Patient pt 
using AlNoorHospital.dbo.Patient ps ON (pt.patient_id = ps.patient_id)

When Matched Then
    Update 
    Set Name = ps.Name,
        Gender = ps.Gender, 
        Age = ps.Age,
        Addres = ps.Addres,
        admission_Date = ps.admission_Date

When Not Matched Then 
    insert into dbo.Patient(pt.Patient_id , pt.Name , pt.Gender , pt.Age , pt.addres , pt.admission_Date)
    values(ps.Patient_id,ps.Name,ps.Gender,ps.Age,ps.addres,ps.admission_Date);

Answer 1

由于MERGE语句已经定义了目标表，因此INSERT语句必须如下所示：

When Not Matched Then 
    insert (Patient_id, Name, Gender, Age, addres, admission_Date)
    values(ps.Patient_id, ps.Name, ps.Gender, ps.Age, ps.addres, ps.admission_Date);

INSERT之后不能有INTO tableName子句-只是要定位的列的列表。
