我正在使用Postgres的pg-slick扩展。我尝试在where子句中进行计算,但是我没有得到它的工作。它总是说:有趣的时间戳计算
value - is not a member of java.sql.Timestamp
筛选子句:
.filter(r => Timestamp.from(Instant.now()) - r.lastActivity < Duration.ofMinutes(30))
其中lastActivity是:
def lastActivity = column[Timestamp]("last_activity")
和我的Postgres的驱动程序是:
trait MyPostgresDriver extends ExPostgresProfile
with PgPostGISSupport
with PgDate2Support
with PgEnumSupport {
override val api: API = new API {}
///
trait API extends super.API
with PostGISImplicits
with DateTimeImplicits
with PostGISAssistants {
}
}
object MyPostgresDriver extends MyPostgresDriver
