hi, need help with svn command checkout

hello,

i am new to SVN.

i build a system that store revision id when a branch is ready for QA.
the developer use "ready to qa" string in his comment when commit.
there is a post commit script that collect the revision and insert it to a
DB.

the QA goes to a web page that populate the "ready to QA" projects.
after the QA choose the project he wants to check, the web page generate
install_rev.bat file for the QA to run on his machine.

until this point everything is working like it should.

my question is whats the command that should be in install_rev.bat file?

i want that the QA will start from fresh. for example if now the QA checks
for a project "mobile" revision 1000.
and he wants to check after that "mobile" revision 900.

the environment should be clean from revision 1000 files and folders and
should have only 900 files and folders.

whats the command i should use?
i cant delete the folder, fresh chcekout takes about 20 minutes.

thanks
