MySQL returned datatype and python outputs different type for different functions -

-

I have a lot of problems with MySQL returns and it has been inserted into a QT table with Python. To use data = cursor.fetchall () 

 : for i category (data): sqlTableWidget.setItem (index, i, QtGui.QTableWidgetItem (data [i]) index = index1   
 Basically I would have kept str () around the return, and it used to work for everything, except its That when I am abroad Unicode problems on language and date time so now I did not insert str () and foreign language on the table. However, now there are some problems with some strings  
 1) I do not include that time When I type  type (data [i]) , it returns  datetime  and when I call it the  data [i] = data [i] .strftime ( "% Y-% m-% d% H:% M:% S")  It tells me  'Tupal' does not support object item assignment   
 2) Then I Just passed for that time. Now I try to get the integer to display. If data [i] == 1: print data [i] print type (data [i]) data [i] = str (data [i])    / Pre> 
 This results in the following:  
  gt; 1 >> (type 'long')> gt; & Gt; Type error: does not support 'Tulle' object   
 In addition, if I try to print  
  print list (data [i])   
 It returns:  
  typeError: The 'long' object is not recurring.   
 In addition, / P> 
  if there is no data [i]: data [i] = 'no data' sqlTableWidget.setItem (index, i, qtigui.quitebitalititum (data [i]))   
 returns:  
  QTableWidgetItem (QtableWidgetItem): Logic 1 Unexpected type 'NoneType'   
 I must be missing something fundamental about my return what caused it?   
 
 
 You can not change the data from the fetchall method because it is a Tupal and not a list. The easiest to decide:  
  data = [for the list (i) I cursor.fetchol ()]

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
