在 SQLDeveloper 中使用以下查询来测试合并一切正常：

merge into proj.person_registry pr 
using ( 
select null as id, 
'69696696553' as code, 
'TESTYMC' as name, 
'WHATEVER' as firstname, 
'M' as cl_gender, 
'E' as cl_status, 
null as birth_date, 
null as death_date, 
null as citizen_country_code, 
null as country_code, 
null as location_code, 
null as zip, 
'SOMETOWN' as aadress, 
null as date_updated, 
null as date_created, 
null as aadress_date 
from dual) t on (pr.code = t.code) 
when matched then update set 
pr.name                 = t.name, 
pr.firstname            = t.firstname, 
pr.cl_gender            = t.cl_gender, 
pr.cl_status            = t.cl_status, 
pr.birth_date           = t.birth_date, 
pr.death_date           = t.death_date, 
pr.citizen_country_code = t.citizen_country_code, 
pr.country_code         = t.country_code, 
pr.location_code        = t.location_code, 
pr.zip                  = t.zip, 
pr.aadress              = t.aadress, 
pr.aadress_date         = t.aadress_date 
when not matched then 
insert values (t.id, t.code, t.name, t.firstname, t.cl_gender, t.cl_status, t.birth_date, t.death_date, t.citizen_country_code, t.country_code, t.location_code, t.zip, t.aadress, t.date_created, t.date_updated, t.aadress_date);

但是尝试使用 jdbc 在我的代码中执行它会引发 BadSqlGrammarException，原因如下： java.sql.SQLException: ORA-00900: invalid SQL statement

您可能已经满足了这一点，但您可能需要转义查询中的单引号。

我还发现，在将查询传递给 Oracle 时，在我的情况下，使用 OPENQUERY 从 SQL Server 传递查询时，分号会使查询失败，并显示该 Oracle 错误代码。

它可能就像从语句末尾删除分号一样简单
