Question

我有以下搜索电影

select * from movie where title like ? or cast like ? or director like ? or description like ?  order by votes desc limit 40

如何通过标题中包含搜索字词的电影订购然后投票？

like order by termInTile, votes desc limit 40

String resultSql = "select * from movie where title like ? or cast like ? or director like ? or description like ?  order by votes desc limit 40 ";
statment = connect.prepareStatement(resultSql);
statment.setString(1, "%" + term + "%");
statment.setString(2, "%" + term + "%");
statment.setString(3, "%" + term + "%");
rs = statment.executeQuery();

while (rs.next()) {
    if (movies == null) {
        movies = new ArrayList<Movie>();
    }
    movies.add(getMovieFromRs(rs));
}

Answer 1

您可以使用order by子句：

select *
from movie
where title like ? or cast like ? or director like ? or description like ? 
order by (title like ?) desc,
         votes desc
limit 40;

title like ?将返回一个布尔值，其中1表示真值。 desc会将这些放在第一位。请注意，在调用查询时，您必须包含其他参数。或者使用命名参数，因此您可以多次引用单个参数。

Answer 2

回答标题中提出的问题：

SELECT *
FROM movie
WHERE title like ? or cast like ? or director like ? or description like ? 
ORDER BY (CASE WHEN title like ? THEN 1 WHEN description like ? THEN 2 ELSE 3 END)
LIMIT 40
;

如何搜索电影，并在标题中使用搜索字词中的搜索字词来搜索带有搜索字词的结果
