| SQL*Plus |
SET SERVEROUTPUT ON in SQL*Plus is equivalent to:
dbms_output.enable(buffer_size => NULL); |
| |
| DISABLE |
| Disable DBMS_OUTPUT and reset the buffer size
to the default |
dbms_output.disable; |
|
exec dbms_output.disable; |
| |
| ENABLE |
|
Enable DBMS_OUTPUT and set the buffer size. The buffer size can be between 1 and 1,000,000 |
dbms_output.enable(buffer_size IN
INTEGER DEFAULT 20000); |
| exec dbms_output.enable(1000000); |

| GET_LINE |
Returns a single line of buffered information |
dbms_output.get_line(line OUT VARCHAR2, status OUT INTEGER); |
