Question

当我的应用尝试创建sqlite表时，我收到语法错误。

这是创建表格的代码：

@Override
public void onCreate(SQLiteDatabase db) {
    String SQL = pictureTable();
    db.execSQL(SQL);
}

private String pictureTable() {
    return "CREATE TABLE geophoto_db_pictures ( picid integer,"
            + "name character varying(50),"
            + "city character varying(20) NOT NULL DEFAULT 'Unknown',"
            + "zipcode character varying(20) NOT NULL DEFAULT 'Unknown',"
            + "country character varying(20) NOT NULL DEFAULT 'Unknown',"
            + "picdate datetime NOT NULL DEFAULT DATETIME('now'),"
            + "tags character varying(200)," + "image BLOB NOT NULL,"
            + "uploaded integer NOT NULL DEFAULT 0, PRIMARY KEY (picid))";
}

错误是： android.database.sqlite.SQLiteException：near＆＃34;（＆＃34;：sytax error（code 1）

非常感谢任何帮助！

默认值不能使用函数调用。

但是，您可以使用`CURRENT_TIMESTAMP'变量：

CREATE TABLE
    ...
    picdate datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
    ...
