可以在 SQL IN 子句中放置超过 1000 个项目吗?我们一直遇到无法处理 Oracle 数据库的问题.

It is possible to put more than 1000 items in the SQL IN clause? We have been getting issues with our Oracle database not being able to handle it.

如果是，我们如何在 SQL IN 子句中放入 1000 多个项目?

IF yes, how do we put more than 1000 items in the SQL IN clause?

如果没有，我还能做什么?

IF not, what else can I do?

推荐答案

您应该将 IN 子句转换为 INNER JOIN 子句.

You should transform the IN clauses to INNER JOIN clauses.

您可以像这样转换查询

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

在另一个类似的查询中.

in a query like this other one.

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

你也会获得很多表现
