oracle merge into 的这个该怎么用

Posted 2023-03-09

merge into TB_SM200_sz_bak a
using tb_sm200 b
on (a.order_no=b.order_no and a.KIJUN_YM=b.KIJUN_YM)
when matched then update set
a.TATGET_AMT=b.TATGET_AMT,

a.close_YM=b.close_YM,
a.doc_no=b. doc_no,

where a.order_no=b.order_no;

when not matched then insert

这个有没有错??

参考技术A Oracle9i引入了MERGE命令,你能够在一个SQL语句中对一个表同时执行inserts和updates操作. MERGE命令从一个或多个数据源中选择行来updating或inserting到一个或多个表.在Oracle10g中MERGE有如下一些改进：
1、UPDATE或INSERT子句是可选的
2、UPDATE和INSERT子句可以加WHERE子句
3、在ON条件中使用常量过滤谓词来insert所有的行到目标表中,不需要连接源表和目标表
4、UPDATE子句后面可以跟DELETE子句来去除一些不需要的行
语法:
MERGEHINTINTO SCHEMA .TABLE T_ALIAS
USINGSCHEMA . TABLE | VIEW |SUBQUERY T_ALIAS
ON (CONDITION)
WHENMATCHEDTHEN MERGE_UPDATE_CLAUSE
WHENNOTMATCHED THEN MERGE_INSERT_CLAUSE / MERGE_DELETE_CLAUSE; 参考技术B 语法如下：
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

应该没错追问
