我正在使用ORMLite,使用Table RecentSearch:

@DatabaseTable(tableName = LocalStorageConfig.SQL_RECENTS_TABLE_NAME)
public class RecentSearch {

    @DatabaseField
    public String search_text;
    public static String SQL_SEARCH_FIELD = "search_text";

    @DatabaseField
    public String location_text;
    public static String SQL_LOCATION_FIELD = "location_text";

    @DatabaseField
    public Date creation_date = new Date();
    public static String SQL_CREATION_DATE_FIELD = "creation_date";

它几乎一直在工作,但是当我发现包含'的字符串的情况时,它似乎是一个问题.你知道怎么解决这个问题吗？我找不到我要找的东西.

这是我删除最近的功能

public boolean deleteRecent(RecentSearch search) {
    try {
        Dao<RecentSearch, Integer> recentsDao = recentsSqlManager.getRecentsDao();
        DeleteBuilder<RecentSearch, Integer> deleteBuilder = recentsDao.deleteBuilder();

        deleteBuilder.where().eq(RecentSearch.SQL_SEARCH_FIELD, search.getSearch_text()).and().eq(RecentSearch.SQL_LOCATION_FIELD, search.location_text);
        recentsDao.delete(deleteBuilder.prepare());
        return true;
    } catch (Exception e) {
        Log.e(TAG, "Database exception", e);
        return false;
    }
} …

我正在使用ORM(ORMlite),我的所有调用都进行得很顺利,直到我收到以下错误.

我很困惑,哪些是错的.我从这些行调用搜索:

// get our query builder from the DAO
QueryBuilder<Story, Integer> queryBuilder = StoryDao.queryBuilder();
// the 'title' field must be equal to title (a variable)
queryBuilder.where().eq(Story.TITLE_FIELD_NAME, title);
// prepare our sql statement
PreparedQuery<Story> preparedQuery = queryBuilder.prepare();
// query for all stories that have that title
List<Story> accountList = StoryDao.query(preparedQuery);
