Question

我有以下表格列

public static final String SHOWID = "show_id";
    public static final String SHOWNAME = "show_name";
    public static final String SHOWSEASON = "season_name";
    public static final String EPISODENAME = "episode_name";
    public static final String EPISODESTATUS = "episode_status";

我想进行以下查询

SELECT episode_name , episode_status FROM tv_show WHERE show_name='aName' AND season_name='aSeason'";

怎么做？

我不想使用db.rawQuery（...）

我想用这样的东西

db.query(
                true,
                DBTABLE,
                new String[] {SHOWSEASON}, 
                SHOWNAME + " like ?",
                new String[] { String.valueOf(shName) },
                null, null, null, null
                );

Answer 1

这是基本的SQL，快速搜索，您可以找到解决方案：

SELECT episode_name , episode_status FROM tv_show WHERE show_name='aName' AND season_name='aSeason'";

您必须使用AND，而不是&

您可以执行类似的操作，并在需要时将'='替换为'LIKE'：

Cursor cursor = db.query(TVSHOW_TABLE, new String[] { EPOSIDENAME, EPISODESTATUS }, SHOWNAME + "='" + aName + "' AND " + SEASONNAME + "='" + aSeason + "'", null, null, null, null);

Android sqlite有多个在哪里
