我使用Exposed作为我的数据库库,当我尝试运行我的代码时出现这些错误:

代码片段SQLObjects.kt
:
object Songs : Table() {
val _id = integer("_id").autoIncrement().primaryKey() // Line 14
val songId = integer("song_id")
val title = text("title")
val artist = text("artist")
val levelBSC = integer("level_bsc")
val levelADV = integer("level_adv")
val levelEXT = integer("level_ext")
}
我想我正确地遵循了示例代码,但我无法弄清楚是什么引发了这些。
