Yii ‘s CArrayDataProvider is very helpful to display model relation data's directly on it.But it is truely a confusing one because by default it will assume a table field named “id” as primary key for its pagination purpose and what if you dont have field named “id” as primary key on your table? so its truely confusing and if you tried to display without an “id” field on ur table you will get an error like “yourmodel.id is not defined”.

find doubletts by db fields.
in this example i will check doublets for 3 tabelfields (col1,col2,col3).
so i will get a subquery with the condition, select and grouping of the tablefields. the having with COUNT() > 1 means: find all records more then one result.
If you are testing your app and use urlManager in your config, sometimes you will find a problem: you want to test your site independing from urlManager settings. in that way you need to extend your WebTestCase class by this method:
When we are doing an insert of huge no.of rows into an SQL table ,Normally we will try to write separate insert quries this may lead us to a long duration of execution time and we can increase the speed of executing SQL quries by adding all the rows into a single insert query.
Changing the way a CGridView is rendered from the configuration file, or through behaviors specified at the moment it is used, is handy to extend a CGridView without creating tons of different classes for it.
I am surprised that this is not in the default implementation, so I made my default CGridView implementation.
