在Android Sqlite数据库中更新byte []

Question

I have successfully added a blob file into my database. but when i try to update it gives errors. I tried two methods here is my code.I searched but everywhere i found adding in database not updating a byte[].

1- First i tried to save simple pro byte[]. but it said it didn't recognize the value of byte[].

2- Then i tried Arrays.toString(pro) but no such column.

      public void profile(String status,byte[] pro, SQLiteDatabase db){
    ContentValues sv = new ContentValues();
    sv.put(mDatabase.Tableinfo.status, status);
    sv.put(mDatabase.Tableinfo.Pic, pro) ;
    db.update(mDatabase.Tableinfo.Table_Name, sv, mDatabase.Tableinfo.status + "=" + status + " and " + mDatabase.Tableinfo.Pic + "=" + Arrays.toString(pro), null);
   // db.insert(mDatabase.Tableinfo.Table_Name, null, sv);

   android.database.sqlite.SQLiteException: near "and": syntax error (code 1): , while compiling: UPDATE User SET status=?,Pro_pic=? WHERE status= and Pro_pic=[-119, 80, 78, 71, 13, 10, 26, 10, 0, 0, 0, 13, 73, 72, 68, 82, 0, 0, 0, 120, 0, 0, 0, 1............ and to infinite .

You would probably suggest this but I even tried this but can't add a byte[] into String array.

  mDatabase.Tableinfo.status + "=? and " +mDatabase.Tableinfo.Pic +"=?", new String[]{status,pro(this is a byte array)}, null);

Answer 1

Add single quotation marks may works

db.update(mDatabase.Tableinfo.Table_Name, sv, mDatabase.Tableinfo.status  "="    
    + status + " and " + mDatabase.Tableinfo.Pic + "= '"+Arrays.toString(pro)+"'", null);

Answer 2

Note - I have only one row So just doing this solved my problem. No selection no other things.

     db.update(mDatabase.Tableinfo.Table_Name, sv,null, null);
