JDBIWrapper

class JDBIWrapper extends AnyRef

Provides idiomatic Scala enhancements to the JDBI API.

Examples -

dbi.open[DAO] to open a handle and attach a new sql object of the specified type to that handle

dbi.daoFor[DAO] to create a new sql object which will obtain and release connections from this dbi instance, as it needs to, and can, respectively

When in scope, you can create transactions using for comprehension. For instance -

 for { handle <- dbi.transaction
      dao1   <- handle.attachable[Dao1]
       ...
      daoN   <- handle.attachable[DaoN] } yield {

      dao1.some_function()
      ...
      daoN.some_other_function()
}
