The ":" operator refers to the block name .For example ur block student has an item stuid.Then when u have to access this u will write :your_block_name.your_item_name.In exaple
:student.stuid.
I hope u will got this point

In order to assign or access a value of any object in a form you need to identify the name of that object using the operator ":".
in your query, what you are doing is selecting and assigning the value of studid,studname,ftpt_status...etc into the item named studid,studname,ftpt_status. And to uniquely identify each of this item you are mentioning the block name preciding each item using the operator ":".
i,e :studblock.studid. where studblock is the block name and studid is the item name.
when u r assigning values to a item then make sure your query returns only one record.
