I need to include single quotes in dbms_output statement. I’ve tried this:

 dbms_output.put_line('\''first_name||'\'');

Here first_name is variable; I need to display this inside single quotes.

    you’d escape by doubling up:

     dbms_output.put_line('''' || first_name || '''');

    or using the q-quote mechanism:

     dbms_output.put_line(q'[']'||first_name||q'[']');

    eg:

    SQL> var b1 varchar2(30)
SQL> exec :b1 := 'this is a test';

PL/SQL procedure successfully completed.

SQL> exec  dbms_output.put_line(q'[']'||:b1||q'[']');
'this is a test'

PL/SQL procedure successfully completed.

SQL> exec  dbms_output.put_line(''''||:b1||'''');
'this is a test'

PL/SQL procedure successfully completed.

SQL> exec  dbms_output.put_line(chr(39)||:b1||chr(39));
'this is a test'

PL/SQL procedure successfully completed.
