Binding resultset of output of 2query and returing back from PL/SQL

[manush]

Hi,

I have two string containing two queries like
str1 VARCHAR2(1000);
str2 VARCHAR2(1000);

str1 := Select 'Test1' from dual;
str2 := Select 'Test2' from dual;

In PL/SQL, to get the result set of ONE query I use

OPEN o_result_set FOR str1;

Where o_result_set is IN OUT refcursor in stored procedure's parameter;

Now I have to get the out put of two different query, then to combine them and send it back via OUT parameter.

Pls suggest a solution
