ORA-00933: SQL 命令未在查询中正确结束 [重复]

Question

我试图将数据从 table1 复制到 table2，但我得到 ORA-00933 SQL 命令未在 Oracle SQL 中正确结束，当我在互联网上检查时，我发现查询中没有错误，有人可以帮助我吗？

UPDATE table1
SET    field2 = table2.field2,
       field1 = table2.field1
FROM   table2
WHERE  (table2.MSISDN = table1.MSISDN or table2.IMSI = table1.IMSI )and 
(table2.field2 != table1.field2 or table2.field1 != table1.field1);

Answer 1

试试这个

UPDATE table1
SET    field2 = table2.field2,
       field1 = table2.field1
FROM   table1
left JOIN table2 
ON (table2.MSISDN = table1.MSISDN or table2.IMSI = table1.IMSI ) 
where table2.field2 is NULL or table2.field1 is null;
