Slick SQLite setting PRAGMAS

I'm trying to set a busy timeout to my database to cope with concurrency issues. I'm using SQLite and Slick as the database. To set the PRAGMA I use:

StaticQuery.updateNA("PRAGMA busy_timeout=1000").execute

And to verify I tried

println(StaticQuery.updateNA("PRAGMA busy_timeout").list.head)

But it prints 0 when it should print 1000.

I tried using the sqlu"PRAGMA......".execute as well but it didn't work either.

Any Ideas how I can get around this problem? Thanks!
