orale中的merge語句的SQL如下：

?第一條merge語句

merge into test01 a using (select 1 as id, 'xxxx' as note from dual) b on (a.id=b.id) when matched then update set a.note=b.note when not matched then insert (a.id, a.note) values (b.id, b.note);

第二條merge語句

merge into test01 a using (select 1 as id, 'yyyy' as note from dual) b on (a.id=b.id) when matched then update set a.note=b.note when not matched then insert (a.id, a.note) values (b.id, b.note);

?轉換成HGDB的語法如下：

?第一條merge語句?

WITH upsert as (update test01 m set note='xxxx' where id= 1 RETURNING m.* ), data as (select 1 as id, 'xxxx' as note) insert into test01 select * from data a where not exists(select 1 from upse rt b where a.id=b.id);
