Hello, I am working on a function which has to insert data into a SQL table.

we have to supply the function with number of entry needs to be inserted into the database and the work of the function is to insert the entry into SQL in such a way that 30% of the entry have their type(a column in my db) as 'a' , 20% as 'b' , 40% as 'c' and rest 10% as 'd'.

Is there any way i can do this? Do I need to run 4 while loops?

Thanks.
