Question

尝试在表格中插入数据时遇到问题。表创建和插入的代码如下：

    // Creamos la tabla Montanas
    db.execSQL("CREATE TABLE montanas ("+
            "_id INTEGER PIMARY KEY, "+
            "nombre TEXT, "+
            "sierra TEXT, "+
            "altitud INTEGER, "+
            "longitud REAL, "+
            "latitud REAL, "+
            "categoria INTEGER, "+
            "url TEXT, "+
            "foto TEXT, "+
            "num_visitas INTEGER, "+
            "fecha LONG, "+
            "valoracion REAL, "+
            "comentario TEXT)");

    // Añadimos montanas
    db.execSQL("INSERT INTO montanas VALUES (null, 'Abitigarra', "+
            "'Iturrieta', 1165, 551613.0, 4734431.0, TipoCategoria.CAT1.ordinal(), "+
            "'http://www.mendikat.net/modules.php?name=tracks&id=797', '', 0, "+
            "System.currentTimeMillis(), 0.0, '')");

这是我执行时遇到的错误：

07-21 18:46:16.062: E/SQLiteLog(1485): (1) near "(": syntax error

。。

你能帮助我吗？我无法看清问题是什么。

Answer 1

尝试取出纬度和经度的小数点，就像在表格中将它们作为整数一样。 http://www.sqlite.org/datatype3.html

Answer 2

我认为您想要将TipoCategoria.CAT1.ordinal（）的结果放入而不是将methodname作为字符串...所以我认为您必须将您的sql字符串更改为：

4734431.0," + TipoCategoria.CAT1.ordinal() + "

以及

"" + System.currentTimeMillis() + "

Answer 3

尝试

  db.execSQL("INSERT INTO montanas VALUES (null, 'Abitigarra', "+
            "'Iturrieta', 1165, 551613.0, 4734431.0, "+TipoCategoria.CAT1.ordinal()+", "+
            "'http://www.mendikat.net/modules.php?name=tracks&id=797', '', 0, "+
            System.currentTimeMillis()+", 0.0, '')");

Answer 4

从引号中删除System.currentTimeMillis（）...

db.execSQL("INSERT INTO montanas VALUES (null, 'Abitigarra', "+
        "'Iturrieta', 1165, 551613.0, 4734431.0, TipoCategoria.CAT1.ordinal(), "+
        "'http://www.mendikat.net/modules.php?name=tracks&id=797', '', 0, "+
        System.currentTimeMillis()+", 0.0, '')");

Answer 5

错误是在_id列创建表时应该写入INTEGER PRIMARY KEY的概率，你忘了后者。
