如何使用kotlin exposed调用sequence.nextVal

dependencies {
    implementation("org.jetbrains.exposed:exposed-core:0.32.1")
    implementation("org.jetbrains.exposed:exposed-dao:0.32.1")
    implementation("org.jetbrains.exposed:exposed-jdbc:0.32.1")
    implementation("org.jetbrains.exposed:exposed-java-time:0.32.1")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.5.31")
    implementation("com.h2database:h2:1.4.200")
}

Database.connect("jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;", driver = "org.h2.Driver")

object MyTable : IntIdTable() {
    val value = integer("value")
}

transaction {
    val nextVal = MyTable.slice(MyTable.value.nextVal()).selectAll().single()[MyTable.value.nextVal()]
    println("Next value: $nextVal")
}
