create table sentense中的sqlite異常

Question

我有一個database與兩個表。最近，我插入一個新行（key_today），我得到以下sqliteexception：

android.database.sqlite.SQLiteException: near "text": syntax error: create table tasks (_id integer primary key autoincrement, title text not null,location text not null, body text not null , goaldate text not null , absolutedate text not null , currentdate text not null , prio text not null, done text not null, category text not null, timespent text not null, pososto text not null, father text not null, check text not null); 

我已經改變了方法，以包括新行，但我真的不能找到什麼即時通訊做錯了。

這裏是我的代碼，謝謝你提前

public static final String KEY_TITLE = "title"; 
public static final String KEY_BODY = "body"; 
public static final String KEY_ROWID = "_id"; 
public static final String KEY_FATHER="father";//father's id 
public static final String KEY_location = "location"; 
public static final String KEY_GOAL_DATE = "goaldate"; 
public static final String KEY_ABSOLUTE_DATE = "absolutedate"; 
public static final String KEY_DATE_CURRENT = "currentdate"; 
public static final String KEY_PRIO= "prio"; 
public static final String KEY_DONE = "done"; 
public static final String KEY_CATEGORY = "category"; 
public static final String KEY_TIME_SPEND = "timespent"; 
public static final String KEY_POSOSTO = "pososto"; 
public static final String KEY_TODAY= "check"; 

public static final String KEY_STITLE = "atitle"; 
public static final String KEY_ROID = "_id"; 
public static final String KEY_SCOLOR = "color"; 


private static final String TAG = "ListDatabase"; 
/** 
* @uml.property name="mDbHelper" 
* @uml.associationEnd 
*/ 
private DatabaseHelper mDbHelper; 
private SQLiteDatabase mDb; 

/** 
* Creating database tables 
*/ 
private static final String DATABASE_CREATE = 
    "create table tasks (_id integer primary key autoincrement, " 

    + "title text not null," 
    +"location text not null, " 
    + "body text not null , " 
    +" goaldate text not null , " 
    +" absolutedate text not null , " 
    +" currentdate text not null , " 
    +" prio text not null, " 
    +" done text not null, " 
    +" category text not null, " 
    +" timespent text not null, " 
    +" pososto text not null, " 
    +" father text not null, " 
    +" check text not null);"; 

Answer 1

Check是a reserved word in SQLite;嘗試重命名該列或將其放入（轉義）SQL語句中的雙引號。

Answer 2

這裏是什麼導致了問題：

... check text not null) 
    ^^^^^ 

check是SQLite中的關鍵詞（和SQL一般）。

把它放在這樣的雙引號，以避免這樣的問題：

... "check" text not null)
