i have the below procedure, but its not printing the rows of the table
CREATE OR REPLACE PROCEDURE abc(tname varchar2) AS
BEGIN
execute immediate 'select * from '||tname;
end;
Your help is highly appreciated.

Answer 1

So you want SQL*Plus to display the output? That's generally a bad idea, since the client application has to be explicitly set up to display output in the first place. If you have more than a small amount of data, you can also very easily exceed the buffer size.
What is the business purpose of this request? Whatever you're trying to accomplish, there's very likely a better option.
If you go down this path, you're going to need to use the DBMS_SQL package rather than native dynamic SQL. You could probably adapt some of the routines Tom Kyte uses to generate flat files.
