This morning, a stored procedure has been written for many times. It can be easily written, reported for various errors, various confusions, and searched on the Internet, I did not mention the ending answer provided on the Forum. Let's take a look at the original program. I commented out some of my missing jump-Out Loop statements.

Declare
Type cur_type is ref cursor;
Cur_emp cur_type;
R_emp emp % rowtype;
V_ SQL varchar2 (500 );
Begin
V_ SQL: = 'select * from emp where sal>: sal ';
Open cur_emp for v_ SQL using & enter the salary :;
Loop
Fetch cur_emp into r_emp;
-- Exit when cur_emp % notfound;
Dbms_output.put_line (r_emp.ename | '-' | r_emp.sal );
End loop;
Close cur_emp;
End;

Oracle error:

Suddenly, I found this step out of the loop. The error is very simple. The key is that the error is reported. set serveroutput size 100000000 on the Internet, or set serveroutput to a larger value, or set serveroutput on size unlimited has been tried. No. Serveroutput is the dbms_output service in pl/SQL. When this service is enabled, the service can print the output content on the console. Obviously, this error refers to buffer overflow, which is easily caused by an error such as an endless loop. Unfortunately, I didn't think of it for a moment. Now, Let's sum up and remember it!
