Question

我有以下SQL代码（这是我到目前为止做的多少）：

MERGE INTO SCHEMA_1.TABLE_1 table1
USING
(

SELECT *


FROM  SCHEMA_2.TABLE_2 table2
LEFT JOIN SCHEMA_2.VIEW_1 view1
ON table2.COLUMN_4 = view1.COLUMN_1

)t2
ON(table1.COLUMN_2 = t2.COLUMN_5)
WHEN MATCHED THEN UPDATE SET
table1.COLUMN_3 = t2.COLUMN_6
where table1.COLUMN_2 in
(
select  

    table1.COLUMN_2
    from 
        SCHEMA_1.TABLE_1 table1, 
    SCHEMA1.TABLE_3 table3, 
    SCHEMA1.TABLE_4 table4,
    SCHEMA1.TABLE_5 table5,
    SCHEMA1.TABLE_6 table6,
    SCHEMA1.TABLE_7 table7
    where 
        table4.COLUMN_7 = table3.COLUMN_8 and
    table5.COLUMN_9 = table4.COLUMN_10 and
    table5.COLUMN_11 = table1.COLUMN_12 and
    table4.COLUMN_13 = table7.COLUMN_14 and
    table7.COLUMN_15 = table6.COLUMN_16 and 
    table6.COLUMN_17 = 'DOL' and
    table4.COLUMN_18 = 1 and 
    table1.COLUMN_2 is not null and 
    table1.COLUMN_3 is null
    order by 
        table1.COLUMN_19 desc
);

但是我收到以下错误消息：

SQL Error: ORA-00907: missing right parenthesis 00907. 00000 - "missing right parenthesis"

为什么会出现这个错误？在哪里更改代码以使其工作？

感谢您的帮助！

好吧，您必须从UPDATE语句中删除ORDER BY。我没有你的表结构和数据，试试

MERGE INTO schema_1.table_1 table1
     USING (SELECT *
              FROM    schema_2.table_2 table2
                   LEFT JOIN
                      schema_2.view_1 view1
                   ON table2.column_4 = view1.column_1) t2
        ON (table1.column_2 = t2.column_5)
WHEN MATCHED
THEN
   UPDATE SET
      table1.column_3 = t2.column_6
           WHERE table1.column_2 IN
                    (SELECT table1.column_2
                       FROM schema_1.table_1 table1,
                            schema1.table_3 table3,
                            schema1.table_4 table4,
                            schema1.table_5 table5,
                            schema1.table_6 table6,
                            schema1.table_7 table7
                      WHERE     table4.column_7 = table3.column_8
                            AND table5.column_9 = table4.column_10
                            AND table5.column_11 = table1.column_12
                            AND table4.column_13 = table7.column_14
                            AND table7.column_15 = table6.column_16
                            AND table6.column_17 = 'DOL'
                            AND table4.column_18 = 1
                            AND table1.column_2 IS NOT NULL
                            AND table1.column_3 IS NULL)

Oracle sql MERGE INTO带有double where子句
