只有一個表和一堆值的Oracle SQL合併語句

Question

我正在使用Spring JDBC和Oracle SQL。

使用SpringJDBC類MapSqlParameterSource，我映射了我想要合併的數據。

現在我想使用合併語句來更新/插入數據庫表。我只有一張桌子和一堆我想融入其中的參數。

merge into proj.person_registry pr 
using (! parameters should go here somehow?) 
on (pr.id = :id or pr.code = :code) 
when matched then 
update set pr.code    = :code, 
     pr.name     = :name, 
     pr.firstname   = :firstname, 
     pr.cl_gender   = :cl_gender, 
     pr.cl_status   = :cl_status, 
     pr.aadress    = :aadress, 
     pr.aadress_date   = :aadress_date 
when not matched then 
insert values (:code, :name, :firstname, :cl_gender, :cl_status, ;aadress, :aadress_date); 

我一定要使用關鍵字在某種程度上創造了臨時表或有另一種方式？我將如何去合併這樣？

還有兩個唯一的鍵pr.id和pr.code。有時參數：ID是null，當發生這種情況時，我想要達到基於pr.code獲取匹配的更新語句：代碼。如果我的更新包含該生產線將它仍然工作：

update set pr.code    = :code, 

Answer 1

這應該工作：

merge into proj.person_registry pr 
using ( 
    select 42 as id 
     'xyz' as code, 
     'Dent' as name, 
     'Arthur' as firstname, 
     'male' as cl_gender 
     'closed' as cl_status, 
     'Somewher' as aaddress, 
     current_date as aaddress_date 
    from dual 
) t on (pr.id = t.id or pr.code = t.code) 
when matched then 
update set pr.code    = t.code, 
     pr.name     = t.name, 
     pr.firstname   = t.firstname, 
     pr.cl_gender   = t.cl_gender, 
     pr.cl_status   = t.cl_status, 
     pr.aadress    = t.aadress, 
     pr.aadress_date   = t.aadress_date 
when not matched then 
insert values (t.code, t.name, t.firstname, t.cl_gender, t.cl_status, ;aadress, t.aadress_date); 

我不熟悉Spring的JDBC模板，但參數在select ... from dual查詢替換實際值佔位符應該工作。
