Android SQLite数据库onCreate错误

Question

我是SQLite的新手，我正在尝试着去创建一个用于学习目的的基础数据库。

在我的主，我宣布一个新的DbHelper和SQLiteDatabase ..

// Open Database 
    DbHelper dbHelper = new DbHelper(Main.this);   
    SQLiteDatabase db = dbHelper.getWritableDatabase(); 

我DbHelper类..

public class DbHelper extends SQLiteOpenHelper 
{ 
private static final String TAG = "DbHelper"; 

public static final String DB_NAME = "exerciseDB"; 
public static final int DB_VERSION = 1; // User defined - up to you 
public static final String TABLE = "Exercises"; 

// Try keep column names consistent with object names 
public static final String C_ID = "_id"; // "_id" special 
public static final String C_PARENTEXERCISE = "parentExercise"; 
public static final String C_SETNO = "setNo"; 
public static final String C_REPSANDWEIGHT = "repsAndWeight"; 

public String sql; 

Context context; 

public DbHelper(Context context) 
{ 
    super(context, DB_NAME, null, DB_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) 
{ 
    // SQL commands 
    sql = String.format(
      "CREATE TABLE %s (%s INT PRIMARY KEY %s TEXT %s INT %s TEXT);", 
      TABLE, C_ID, C_PARENTEXERCISE, C_SETNO, C_REPSANDWEIGHT); 

    // Prints out sql String to Logcat 
    Log.d(TAG, "onCreate sql: " + sql); 

    db.execSQL(sql); // Executes the SQL commands 
} 

@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) 
{ 
    // Maintain users data first 
    db.execSQL("drop table if exists " + TABLE); // Deletes table if it 
                // exists 

    Log.d(TAG, "onUpdata dropped table" + TABLE); 

    // Recreate database 
    this.onCreate(db); 
} 

public String getSQLcmd() 
{ 
    return sql;  
} 

}

SQL命令的输出logcat中是我相信它应该是..

onCreate sql: CREATE TABLE Exercises (_id INT PRIMARY KEY parentExercise TEXT setNo INT repsAndWeight TEXT); 

logcat中也说：

11-10 17:44:14.702: E/SQLiteLog(13053): (1) near "parentExercise": syntax error 

但我似乎无法看到什么错什么parentExercise有关。

任何帮助将不胜感激。

干杯。

查询应该像

CREATE TABLE Exercises (_id INT PRIMARY KEY, parentExercise TEXT, setNo INT, repsAndWeight TEXT)
