like i want to see the table or description of any table it show 2 instead of showing the table.

SQL&gt; select * from dual

SQL&gt; select * from user_objects
  2
SQL&gt;
You need to terminate the SQL statement with a semicolon (;) or a put a slash (/) in the new line instead of hitting Enter. For example: select * from dual;. Otherwise SQLPlus will believe you have not finished your SQL statement, and it starts counting the lines. 2 is actually a line number, it is the 2nd line of your SQL statement. If you type nothing here and just hit Enter, SQL*Plus will terminate your statement and return the prompt, it can not handle empty lines.
