INPUT
I[NPUT] [text]
Inserts one or more lines of text into the buffer. The lines are inserted after the current line. When you issue the INSERT command with no text after it, SQL*Plus puts you in insert mode, allowing you to type as many lines as you like. Here’s an example of INPUT being used:
SQL> L 1 SELECT 2* FROM dual SQL> L 1 1* SELECT SQL> I * SQL> L 1 SELECT 2 * 3* FROM dual
The text is the text you want to insert. Use this if you are inserting only one line.
