android sqlite - How to Add table in SQliteDatabase -

-

I want to add a table to the database and add a column and save the information and click it on the second button. To do this, if the table already exists, it is the only code I use, but it will insert information only after giving an error. 

  button insert_info = (Button) searching for Vivibiaiaidi (Arkdkbtn 1); insert_info.setOnClickListener (New OnClickListener () {@Override public void onClick (View v) {// TODO Auto-generated method stub SQLiteDatabase db; try {final EditText txt_field1 = (EditText) findViewById (R.id.editText1); string Per_Name = txt_field1.getText () putting toString () ;. db = openOrCreateDatabase ( "sez.db", SQLiteDatabase.CREATE_IF_NECESSARY, null); string Query_createTable = "Create table sezInformation (name VARCHAR (100))", string Query_insert = " SezInformation (name) values ​​( "+ Per_Name +") ", db.execSQL (Query_insert);} catch (exception e) {Toast.makeText (WelomePerson.this," error "+ e.toString (), Toast.LENGTH_LONG) Show ();}}});   
 Even when I enter the values ​​I  Khan  or  Aditekt  Click on fields and buttons    There is no such column: When Khan joins the information (name) Value (Khan)   
 Please also tell me how to recover the same saved data in TextView Please. Use   
 
 
 or  if the table instead of the  CREATE TABLE  does not make Are . Also, make sure to use 2 different  execSQL ()  commands (to create and insert a table), or it will not work, because  you can not execute multiple commands Once .

I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
