Execute (or re-execute) commands in the SQL*Plus buffer
I feel confused about sql plus / command. by defination, it Execute (or re-execute) commands in the SQL*Plus buffer. how do I know whether it execete or re-execute a command?
for example, I run a select statement, seems I have to type / to get result. when I run a create table statement, it seems run twice with / and I got table exists error.
Could someone clearify when should / be used and when not to use it.
