Write your PL/SQL code to output string value
SQL> SQL>-- from w ww. ja v a 2 s. co m SQL> declare 2 my_val varchar2(256):='Hello, World!'; 3 begin 4 dbms_output.put_line(my_val); 5 end; 6 / Hello, World! PL/SQL procedure successfully completed. SQL>
Each complete line of the PL/SQL code must end with a semicolon ;.
To run the code, type / at the beginning of the first blank line after the last line of the code.
/ is a SQL*Plus command to execute the last SQL or PL/SQL statement.
The DBMS_OUTPUT.PUT_LINE command sends whatever text you passed as a parameter back to the client console.
