I have sql file with many inserts in it for different tables.

When I run this script using TOAD ( a tool for Oracle application Developers from Quest s/w) it works fine without a single error.

But when I run this file in a SQL*Plus, I get error
***** SP2-0027: Input is too long (> 2499 characters) - line ignored *****

and because of this many other insert statements fail giving FK error.

How do I overcome this "SP2-0027"
