PreparedStatement amovie = con.prepareStatement("INSERT INTO actor_movie(actor_ID, movie_ID)"+ "select actor_ID from actor" + "where actor.surname = 'Depp', select movie_ID from movie where movie.title LIKE 'Caribbean%'");

有人可以告诉我这个查询有什么问题吗？我查遍了互联网，但找不到解决方案。

错误消息:

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ', select movie_ID from movie where title LIKE 'Caribbean%'' at line 1

Answer 1

您有语法错误，因为您忘记了 VALUES 并将 SELECT 语句括在括号中。
更改为:

PreparedStatement amovie = con.prepareStatement(
    "INSERT INTO actor_movie(actor_ID, movie_ID) VALUES ((select actor_ID from actor where actor.surname = 'Depp'), (select movie_ID from movie where movie.title LIKE 'Caribbean%'))");
