How to convert microsoft.sql.DateTimeOffset to Date in Anorm? - sql-server

Question

I developing a project developing with Scala, Play framework 2.3.8, Anorm and works with MS SQL database.
Here the code:
val repeatedCardsQuery = SQL("Execute Forms.getListOfRepeatCalls {user}, {cardId}")
DB.withConnection { implicit c =>
val result = repeatedCardsQuery.on("user" -> user.name, "cardId" -> id)().map(row =>
Json.obj(
"Unified_CardNumber" -> row[Long]("scId"),
"ContentSituation_TypeSituationName" -> row[String]("typeOfEventsName"),
"Unified_Date" -> row[Date]("creationDate"),
"InfoPlaceSituation_Address" -> row[String]("address"),
"DescriptionSituation_DescriptionSituation" -> row[Option[String]]("description")
)
).toList
Ok(response(id, "repeats", result))
}
And it gives me runtime error:
play.api.Application$$anon$1: Execution exception[[RuntimeException: Left(TypeDoesNotMatch(Cannot convert 2015-02-14 15:38:15.4089363 +03:00: class microsoft.sql.DateTimeOffset to Date for column ColumnName(.creationDate,Some(creationDate))))]]

Actually, error occurs in this line:
"Unified_Date" -> row[Date]("creationDate"),
How solve that problem, and convert microsoft.sql.DateTimeOffset to Date in this case?

Answer 1

A custom column conversion can be added next to your Anorm call (defined or imported in same class/object which needed to support such type).
import java.util.Date
import microsoft.sql.DateTimeOffset
import anorm.Column
implicit def columnToDate: Column[Date] = Column.nonNull { (value, meta) =>
val MetaDataItem(qualified, nullable, clazz) = meta
value match {
case ms: DateTimeOffset =>
Right(ms.getTimestamp)
case _ =>
Left(TypeDoesNotMatch(s"Cannot convert $value: ${value.asInstanceOf[AnyRef].getClass} to Boolean for column $qualified"))
}
}
Btw it would be much better to work with DB values represented as JDBC dates (java.sql.Date types supported by Anorm).
