variables in sql-statements

Hello

I am creating a script which uses variables. I store the table-names in these variables and I need to uses these variables in sql-statements. How does this work in orcacle?

example:

declare
tab_name varchar2(20);
col_name varchar2(20);

begin
tab_name:='labor';
col_name:='name';

select * from tab_name where col_name='ROM34';

end;

ERRORS:

ORA-06550: line 7, column 15:
PLS-00356: 'TAB_NAME' must name a table to which the user has access
ORA-06550: line 7, column 1:

Thank you for your help.
