'GENERATED_KEY' stuck

[gigacoderr]

Hi, Andrew.

Thank you for your awesome job!

I've been stuck a little with generated keys using core "insert" function with MySQL, because 'GENERATED_KEY' should be specified instead of key column name.
I.e.

val (count, key) =
session.insert("insert blablabla", mapOf("field" to "value" ...)) {
it.long("GENERATED_KEY")
}

Can you add a small remark about this into documentation?
Thank you. Sorry for my English.
