我有两个不同的表：Table_a和Table_b,它们都有相同的列PartNo和Material_Desc.当PartNo等于时,我希望Table_b中的Material_Desc更新Table_a中的Material_Desc.这是我的疑问
MERGE INTO Table_b
USING ( SELECT t1.rowid AS rid,t2.Material_Desc
FROM Table_b t1
JOIN Table_a t2
ON Table_b.PartNo = Table_a.PartNo )
ON rowid = rid
WHEN MATCHED THEN
UPDATE
SET Table_a.Material_Desc = Table_b.Material_Desc;@H_403_3@
我知道Oracle不支持更新语句的连接,所以我尝试了上面的查询.它仍然给了我ORACLE ORA-00969：缺少ON关键字错误
解决方法
你可以把“(”和“)”.所以写：
ON(rowid = rid)
