Question

上传具有架构

的oracle表1

table1 (col1,col2,col3,Primary key :Col2)。

和upsert语句

MERGE
 INTO table1
USING (
         SELECT ? AS Col1
              , ? AS Col2
              , ? AS Col3
           FROM dual
      ) maybe 
   ON ( maybe.Col2=table1.Col2 )
 WHEN NOT MATCHED THEN
          INSERT VALUES (
               maybe.Col1
             , maybe.Col2
             , maybe.Col3
          )
 WHEN MATCHED THEN
          UPDATE SET table1.Col1=maybe.Col1
               , SET table1.Col3=maybe.Col3
 ;

结果发生了异常 java.sql.BatchUpdateException：ORA-01747：user.table.column，table.column或列规范无效

SET部分还有一个UPDATE：

MERGE INTO table1
USING ( SELECT  ? AS Col1 , ? AS Col2 , ? AS Col3  FROM dual ) maybe
ON ( maybe.Col2=table1.Col2 )
WHEN NOT MATCHED THEN INSERT VALUES ( maybe.Col1, maybe.Col2, maybe.Col3 )
WHEN MATCHED THEN UPDATE SET table1.Col1=maybe.Col1, SET table1.Col3=maybe.Col3
                                                     ^^^

应该是：

WHEN MATCHED THEN UPDATE SET table1.Col1=maybe.Col1, table1.Col3=maybe.Col3

不需要table1说明符，因为更新仅适用于目标表，但它们并不会受到伤害。

使用Merge ORA-01747升级Oracle表
