Extract Just A Single User Data!

[garyopa]

I run a very very large forum, with tons of members and millions of posts, and recently one of the members on the forum have run into a large civic lawsuit, as such our forum going to shortly be subpoena by a Federal US Court to supply all the user's data, his IP records, signup date, and PM's he has, and the 19 posts he made.

I am looking for help or even possible paid, for the proper SQL query I can supply to the vbulletin v3.8.7 database to extract just this single user data in raw form, and or printable form without having to supply the whole 19gb of SQL database, etc.

Any suggestions you have or possible direction on what command to issue to give up just the users data would be most welcome.

Thanks in advance for your input.
