I want to do a fuzzy query for a third-level city, and then I thought of using Room to do local query. I
first made a demo of adding, deleting, modifying and checking the official documents and some articles. I found that there is no introduction about the like query and it is not very detailed. The
document has Similar to this, I can't try it. . .
@Query("SELECT * FROM users WHERE last_name LIKE :strName")
Later, after consulting the data: I tried this, ok
@Query("SELECT * FROM users WHERE last_name LIKE '%' || :strName || '%'")
List<User> loadAllUserLike(String strName);//加一个占位符strName 表示%last_name%
