i need solution to this problem

Hi good morning to all........

I have tables like 1) emp_table (personal_no integer (foreign key),
cdacno varchar (primary key),name varchar);

2) Rank_table (rank_id varchar (primary key), rank_name varchar);

3) Rank_date_table (rank_id (foreign key), rank_date date);

4) Unit_table (unit_id varchar (primarykey), unit_name varchar);

5) Personal_table (per_no varchar (primary key), pername varchar);

My query is ....if I give cdacno I have to get per_no from
personal_table.. With this I have to display rank_name from rank_table
,name from emp_table, unit_name from unit_master..

Like that if I give per_no I have to get cdacno from emp_table.. .. With
this I have to display rank_name from rank_table ,name from emp_table,
unit_name from unit_master..

Doing these things first it has to check when we r giving cdacno..
whether per_no is null or not.. like this if I give per_no it has to
check cdacno is null or not.

Let me know the solution..

But I written one function to this to get per_no if I give
cdacno......................

Thanks & Regards
