Question

我通过使用Slick对oracle表进行插入查询时遇到了一个非常难以理解的问题。我不知道如何定位错误。

"com.typesafe.slick"      %%  "slick"                   % "2.1.0",
 "com.typesafe.slick"      %%  "slick-extensions"        % "2.1.0"

通过插入，我总是得到这个例外：

[DEBUG] - from [scala.slick.jdbc.JdbcBackend.statement] in [pool-1-thread-1] - [Preparing insert statement: insert into "NOTIFICATION_MESSAGE" ("CLIENT_ID","IMPORTANCE","TYPE_ID","ACCOUNT","TITLE","MESSAGE","STATUS","CREATION_DATE")  values (?,?,?,?,?,?,?,?), returning: ID]
[ERROR] - from [mypackage.db.core.OracleDatabaseComponent] in [pool-1-thread-1] - [DB operation failed - error: [An SQLException was provoked by the following failure: java.lang.ArrayIndexOutOfBoundsException: 8]]
mypackage.db.core.DBProcessException: DB operation failed - error: [An SQLException was provoked by the following failure: java.lang.ArrayIndexOutOfBoundsException: 8]

但最奇怪的是，如果我从插入查询中删除一个参数（将作为默认值填充），它将成功执行。它看起来像插入查询中的值数量的限制，但是其他表（其中一些有超过8列）没有问题。也许有人遇到过这个问题或知道如何本地化错误？

表ddl：

create table NOTIFICATION_MESSAGE (
  id         number(20)                   not null,
  client_id          nvarchar2(32)                not null,
  importance         number(1)      default 1     not null,
  type_id            number(2)                    not null,
  account            nvarchar2(32),
  title              nvarchar2(255)               not null,
  message            nvarchar2(2000)              not null,
  status             nvarchar2(32)  default 'NEW' not null,
  creation_date      date       default sysdate   not null
)

光滑的模型：

import com.typesafe.slick.driver.oracle.OracleDriver.simple._   
case class NotificationMessage(
                                    id: Option[Long],
                                    clientId: String,
                                    importance: Int = 1,
                                    typeId: Int,
                                    account: Option[String],
                                    title: String,
                                    message: String,
                                    status: NotificationStatus,
                                    creationDate: Instant
                                    )
    class NotificationMessageTable(tag: Tag) extends Table[NotificationMessage](tag, "NOTIFICATION_MESSAGE") {

        def id = column[Long]("ID", O.PrimaryKey, O.AutoInc)
        def clientId = column[String]("CLIENT_ID", O.NotNull)        
        def importance = column[Int]("IMPORTANCE", O.NotNull)        
        def typeId = column[Int]("TYPE_ID", O.NotNull)        
        def account = column[Option[String]]("ACCOUNT")        
        def title = column[String]("TITLE", O.NotNull)        
        def message = column[String]("MESSAGE", O.NotNull)        
        def status = column[NotificationStatus]("STATUS", O.NotNull)        
        def creationDate = column[Instant]("CREATION_DATE", O.NotNull)        
        override def * : ProvenShape[NotificationMessage] =
          (id.?, clientId, importance, typeId, account, title, message, status, creationDate) <>
            (NotificationMessage.tupled, NotificationMessage.unapply)
    }

Answer 1

删除ID。？

只是id。该列未标记为可选。

如您所见，插入中仅使用了8个参数。

使用Slick 2.1将查询插入Oracle
