不可以。not matched then 后面只能跟insert into 语句。具体语法：merge into table_name using table_view_or_query on condition when matched then update_clause delete where_clause when not matched then insert_clause

第一次接触Oracle的MERGE 的更新或插入数据这个语法,上网了解了下写法,然后就动手应用在自己的项目里,下面有个例子: MERGE INTO Table1 t1 USING ( selectid,countfrom Table1 where id='001') t2 on (t1.id=t2.id) WHEN MATCHED THEN UPDATE SET t1.count=t1.count+1 WHEN NOT MATCHED THEN INSERT (c...
WHEN MATCHED THEN UPDATE SET T2.MONEY=T1.MONEY+T2.MONEY WHEN NOT MATCHED THEN INSERT VALUES (T1.NAME,T1.MONEY); Merge的四大灵活之处 上面讲了Merge的语法和基本使用方法,其实Merge能够很灵活。 1.UPDATE和INSERT动作可仅仅出现其一(9I必须同一时候出现。) ...
WHEN MATCHED和WHEN NOT MATCHED部分都正确地指定了需要更新的列和插入的列。 结论 如果您在使用MERGE语句时遇到“没有足够的值”的错误,请按照上述步骤检查您的语句。通常,这个错误是因为在INSERT或UPDATE子句中指定的列数与提供的值数不匹配。确保所有列都被正确地赋值,并且没有遗漏任何必需的列。如果问题仍然存在...
SQL> MERGE INTO T2 2 USING (SELECT ID, NAME FROM T1) T1 3 ON ( = ) 4 WHEN MATCHED THEN UPDATE 5 SET = SYS. 6 WHEN NOT MATCHED THEN INSERT 7 VALUES (, ); 2行已合并。 显然在SELECT或UPDATE语句中,这样的写法是不能通过语法检查的: ...
merge在Oracle中的用法注意问题: 【样例】 MERGE INTO dest_table dest USING source_table source ON (source.PENDINGCODE = dest.PENDINGCODE and source.PENDINGPERSONID = dest.PENDINGPERSONID) WHEN MATCHED THEN UPDATE SET dest.PENDINGID = source.PENDINGID WHEN NOT MATCHED THEN INSERT VALUES (source....
参考Oracle 的SQL Reference,大家可以看到Merge Statement的语法如下: MERGE [hint] INTO [schema .] table [t_alias] USING [schema .] { table | view | subquery } [t_alias] ON ( condition ) WHEN MATCHED THEN merge_update_clause WHEN NOT MATCHED THEN merge_insert_clause; ...
二、下面先演示一下merge的基本功能 1) matched 和not matched clauses 同时使用 merge into acct a using subs b on (a.msid=b.msid) when MATCHED then update set a.areacode=b.areacode when NOT MATCHED then insert(msid,bill_month,areacode) ...
