[Squirrel-sql-users] need major help please

[squirrel <squ...@ne...>]

I was running a production query. It's saved on a .sql file. When I was
running it, it took a lot of time before Squirrel gave up with an error.
The error I remember is Heap Space Java something in red. I am not able to
do anything on squirrel. It wouldn't respond. I killed it using Task
Manager. I restarted Squirrel. I opened my .sql file again, it was empty. I
looked it up via File Manager and filesize was 0 bytes. OH NO! What should
I do now since I don't have a backup? Is there a temp file that Squirrel
uses?
