Oracle ORA-01795: maximum number of expressions in a list is 1000错误解决

解决办法有两个：

1.使用INNER JOIN替换IN

例：

SELECT  foo   
FROM    bar   
WHERE bar.stuff IN  
       (SELECT  stuff FROM asdf)

转换为

SELECT  b.foo 
FROM    ( 
        SELECT  DISTINCT stuff 
        FROM    asdf ) a 
JOIN    bar b 
ON      b.stuff = a.stuff

2.多个or连接

select * from table_name
  where
      column_name in (V1,V2,V3,...V1000)
  or
      column_name in (V1001,V1002,V1003,...V2000)
  ...
