问题
In Slick 3.1, with the complete redesign of the new API, it seems to be impossible to view the generated SQL statements when doing an insert.
If you have something like this
val action = DBIO.seq(
SomeTables ++= Seq(TableData(1,"First"),TableData(2,"Second"))
)
It doesn't seem you are actually able to see the generated SQL from the action. The result method doesn't actually exist, and variations of statements just print ? in place of the actual values if you don't use DBIO.seq, if you are using DBIO.seq the statements method doesn't actually exist.
Even when using methods such as .transactionally or .withPinnedSession, it doesn't seem to make a difference (however I don't know how this should help).
From observation of all of the methods, it appears that this is impossible?
