    <p>First, wouldn't it be better to avoid having the sql connection inside the <code>__init__</code>? You will have a problem if you want to use this class in the same instance after using <code>__fina__</code>. You could have it in another method and call it and call the connection closing method when needed and commit after each method is executed.</p> <p>Here is what I use : Create a class method that connects to the db and executes a query from an argument,commits and closes connection and you pass any query you want executed as an argument of that method.You can simply call this method anytime you want. And the best about this is that you can create a method that passes multiple queries as arguments before closing db connection. This is specially usefull if have to use sql connections to the same db in another class without using a set of methods each time you need to execute a sql query.</p> <p>Here is a little example I used with MySQLdb module, It's pretty simple but it worked.</p> <pre><code>import MySQLdb class DbQuery: '''Here is the class I talked about''' def __init__(self): '''You can define the main queries here but it's not necessary They can be global variables If you don't have class dependency from which you get variables you might not even need to define __init__''' def Sql_Connect(self): self.db = MySQLdb.connect("localhost","root","","data_db" ) self.cursor = db.cursor() def Sql_Commit(self): self.db.commit() print "Info : Database updated" except: self.db.rollback() print "Error : Database rollback" self.db.close() def Query(self,query): self.Sql_Connect() try : self.cursor.execute(query) self.Sql_Commit() </code></pre> <p>The only thing important is to remember the query structure.</p>

    1. COHi Paul. Thanks for your answer. Sounds a very good idea. May I ask you to publish some code?

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
