How to find if cursor returned rows

Question

If i have a procedure like
create procedure test as
cursor cur_test is
select col
from table;
begin
     delete from tab1 a;
     for var_cur_test in cur_test
     loop
          insert into temp
          values(var_cur_test.col);
     end loop;
     commit;
end;
How do I check if the cursor has returned any rows?
I dont want to delete from tab1 if cursor 'cur_test' does not return any rows and I want to exit out of the proc.
If the cursor returns rows > 0 then I want to delete and do the insert.
Thanks for the help.

Answer 1

The scenario is like this.
There is a schema A which has to run a process and populate its tables and at the end of the process(java program) run the procedure which is in schema B to pull data from schema A and populate the tables in schema B. If there is a case where Schema A's process fails( then Schema A's tables end up with no data), the process is still running the procedure in schema B and deleting the data in tables with no data being inserted.
So, I have to check in the procedure if the tables in Schema A have any data before the process can run the proc.
I tried the solution you provided but it returns no data
CREATE OR REPLACE PROCEDURE MMA_TEST
VAR_CONTRACT_ID VARCHAR2
AS
CURSOR CUR_TEST IS
SELECT CMS_CONTRACT_ID,CMS_PLAN_ID
FROM MMA_PLANS
WHERE CMS_CONTRACT_ID = VAR_CONTRACT_ID;
BEGIN
     for var_cur_test in cur_test
     loop
          if (cur_test%rowcount = 1) then
          delete from temp ;
          end if ;
          insert into temp
          values(var_cur_test.cms_contract_id,var_cur_test.cms_plan_id);
     end loop;
end;
