What’s a very large script?

That’s a subjective question, and the answer will depend somewhat on the hardware specs of your machine.

I got this question yesterday:

I enjoy these questions. They’re 99% of the time, not theoretical. She had obviously ran into some sort of wall.

And the wall looked like this:

There’s no real answer – like I said before, it ‘depends.’ But 600,000+ statements – our editor wasn’t designed to handle files of that size.

If you were to look at what Notepad does to a file on open compared to what we do on files on open and even as you type, click, and scroll – you would understand why.

So, what’s one to do when you want to run those INSERTs?

Just reference the file with the '@' SQL*Plus syntax and execute.
Just reference the file with the ‘@’ SQL*Plus syntax and execute.

One More Tip

It will run even faster if you minimize the script output panel – no need for the tool to write 600k+ update messages to the display…

For very large files like this, you’ll want to make sure you log the output to a secondary file, so consider adding a SPOOL to your script.
