参加インナーと削除 - 構文エラー以下

Question

が私のコードです：上記のコードを実行

try{ 
    String userid = SystemPlatformFactory.getPlatform().getSystem().getUserID(); 
    String[] args = new String[]{userid}; 
    SQLiteDatabase db = this.getWritableDatabase(); 
    db.execSQL("DELETE sa FROM stubout_account sa INNER JOIN stubout s ON sa.parentid = s.objid INNER JOIN area r ON s.areaid = r.objid WHERE r.assigneeid = ?",args); 
    db.close(); 
}catch(Exception e){ 
    e.printStackTrace(); 
    ERROR = "Database Error: " + e.toString(); 
} 

は、このエラーを生成します。エラーの原因である

W/System.err(31732): android.database.sqlite.SQLiteException: near "sa": syntax error (code 1): , while compiling: DELETE sa FROM stubout_account sa INNER JOIN stubout s ON sa.parentid = s.objid INNER JOIN area r ON s.areaid = r.objid WHERE r.assigneeid = ?
