我正在使用 SugarORM 来管理数据库。

public class ExerciseDB extends SugarRecord 
{
    @Column(name = "ex_recordId", unique = true, notNull = true)
    private String ex_recordId;
    private String ex_group;
    private String ex_name;    
    private int ex_cal;

    public ExerciseDB()
    {
    }

    public ExerciseDB(String ex_recordId, String ex_group, String ex_name, int ex_cal) 
    {
        this.ex_recordId = ex_recordId;
        this.ex_group = ex_group;
        this.ex_name = ex_name;
        this.ex_cal = ex_cal;
    }

然后将默认事务加载到ExerciseDB，如下：

ExerciseDB e1= new ExerciseDB("ex1", "Group1", "aaa", 190); save(e1);
ExerciseDB e2= new ExerciseDB("ex2", "Group1", "bbb", 180); save(e2);

问题：

我想列出请求的交易条件到列表视图。

虽然我知道如果检索所有条目可以按如下方式完成：

List<ExerciseDB> Ex_db_record = null;
Ex_db_record = Select.from(ExerciseDB.class).orderBy("ex_recordId").list();

我怎样才能得到一个列表，例如，只有 Group1 记录和按顺序列出的列表ex_recordId？我努力了

Ex_db_record = ExerciseDB.find(ExerciseDB.class, "ex_group = ?", groupping);

但它给出的错误如下：

Caused by: android.database.sqlite.SQLiteException: no such column: ex_group (code 1): , while compiling: SELECT * FROM Ex_Records WHERE ex_group = ?

You probably added ex_group later to the class, so try upgrading the Sugar DB version in your manifest file. It will look like this: 

 <meta-data
            android:name="VERSION"
            android:value="1" />

Update android:value to a higher version. Say 2, in my case.
