我正在使用 ORMLite 和 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,但是当我发现字符串包含'的情况时,它似乎是一个问题。你知道如何解决这个问题吗?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;
}
}
这是我得到的异常:
