* You must create a class extending this one, in the constructor
|

* these variables have to be defined
|

*
|
||||
* - table = name of the view or empty
|
||||
* - select = name of the select
|
||||
* - name = array of column name, match between logic and actual name
|

* - type = array , match between column and type of data
|
||||
* - default = array of column with a default value
|
||||
* - date_format = format of the date
|
||||
*
|
||||
* After you call the parent constructor
|
||||
* @note the view or the table must include an unique key, otherwise the load
|
||||
* doesn't work.
|

*
|

* @class Noalyss_SQL
|

* Match a table or a view into an object, you need to add the code for each table
|
