当我尝试创建一个新数据库时,我收到错误"SQLiteLog:(1)near"order":syntax error"？

Question

这是构造我的查询的代码,execSQL()稍后在我的代码中调用.

    public static final String TABLE_NAME = "active";
    public static final String COLUMN_NAME_ORDER = "order";
    public static final String COLUMN_NAME_TITLE = "title";
    public static final String COLUMN_NAME_CONTENTS = "contents";

    //SQL Queries

    public static final String TEXT_TYPE = " TEXT";
    public static final String COMMA = ",";
    public static final String SQL_CREATE_TABLE_ACTIVE =
            "CREATE TABLE " + ActiveTasks.TABLE_NAME + " (" +
                    ActiveTasks._ID + " INTEGER PRIMARY KEY AUTOINCREMENT" + COMMA +
                    ActiveTasks.COLUMN_NAME_ORDER + TEXT_TYPE + COMMA +
                    ActiveTasks.COLUMN_NAME_TITLE + TEXT_TYPE + COMMA +
                    ActiveTasks.COLUMN_NAME_CONTENTS + TEXT_TYPE +
                    " );";

这是execSQL的声明:

@Override
public void onCreate(SQLiteDatabase db) {
    Log.v(LOG_TAG, DataContract.ActiveTasks.SQL_CREATE_TABLE_ACTIVE);
    db.execSQL(DataContract.ActiveTasks.SQL_CREATE_TABLE_ACTIVE);

}

调用onCreate方法时,我在日志中得到以下内容.

925  16102-16119/xxxxxxxx V/ActiveDatabaseHelper? CREATE TABLE active (_id INTEGER     PRIMARY KEY AUTOINCREMENT,order TEXT,title TEXT,contents TEXT );
 16102-16119/xxxxxxxx E/SQLiteLog? (1) near "order": syntax error

我不相信我忽视了任何事情,如果这是真的,我可能做错了什么？此外,我已确认问题位于Oncreate方法中.

在此先感谢, - 山姆.是的,我已经查看了多个SO问题和答案,描述了我遇到的同样问题.他们对我的情况没有帮助.

Order是Sql关键字.你应该在引号中使用它.有关详细信息,请参阅此处
