问题 I have a Oracle query which I'm executing through shell script and in that my query is getting exceeded the maximum length of 2499. I'm getting error SP2-0027: INPUT IS TOO LONG(> 2499 CHARACTERS) - LINE IGNORED 回答1: Here are some options for working around SQL*Plus line length limitations: Upgrade to 12.2(?) client.

问题 Am I correct in understanding that CREATE OR REPLACE basically means "if the object exists, drop it, then create it either way?" If so, what am I doing wrong?

I don't seem to be able to find much documentation about this syntax. 回答1: This

问题 How can I stop a running SELECT statement by killing the session? The command is continuously giving me output based on the SELECT statement, I want to stop it in between. 回答1: As you keep getting pages of results I'm assuming you started the session in SQL*Plus.
