Type Members

1. class HandleDaoWrapper[A] extends AnyRef

   

2. class HandleWrapper extends AnyRef

   

   Provides idiomatic Scala enhancements to the JDBI API.

3. class JDBITransactionWrapper extends AnyRef

   

   Provides for-comprehension support for composable transactions

4. class JDBIWrapper extends AnyRef

   

   Provides idiomatic Scala enhancements to the JDBI API.

   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()
   }

5. class SimpleMapper[A] extends ResultSetMapper[A]

   

   A simple mapper that only depends on the result set

   A simple mapper that only depends on the result set

   Example - SimpleMapper[(String, String)](r => (r.getString("firstname"), r.getString("lastname")))

   If you used with ResultSetDSL the above example can be further simplified - SimpleMapper[(String, String)](r => (r -> "firstname", r -> "lastname"))

6. class TransactionalWrapper[A <: Transactional[A]] extends AnyRef

   

   Provides enhancements to the Dropwizard jDBI API for transactional DAOs.
