Question

我目前正在使用： - Scala v2.10 - Squeryl v 0.9.6 - MySQL Connector v5.1.28

我已经像这样定义了我的模型类：

class identities (
    val user_id: Long,
    val changed: String,
    val del : Long,
    val standard : Long,
    val name : String,
    val organization : String,
    val email : String,
    @Column("reply-to")
    val reply_to : String,
    val bcc: String,
    val signature: Option[String],
    val html_signature : Long,
    val pass : Option[String]) extends KeyedEntity[Long]
 {
    var identity_id : Long = 0
    def id = identity_id
 }

但每当我尝试使用Squeryl方法在我的数据库上进行简单的选择时，我会收到此错误：

> [RuntimeException: Exception while executing statement : You have an
> error in your SQL syntax; check the manual that corresponds to your
> MySQL server version for the right syntax to use near 'to as

绝对绑定到注释：@Column("reply-to")因为通过修改列的名称，错误消失并且查询已正常执行。不幸的是，更改列的名称对我来说不是一个选项，所以我请你帮忙寻找更好的解决方案。

你肯定需要引用你的专栏，你可以做两件事：

默认情况下，在设置Mysql Adapter时可以引用：

new MySQLAdapter {
     def quoteIdentifier(field: String) = "`"+field+"`"
}

或者您可以更改关系列字段

中的列名称

object Schema1 extends Schema {
  on(identities)(p => declare(
    table1.reply_to is(named("myreplyto"))
  )
}

使用Play Framework和MySQL在Squeryl中使用@Column注释进行问题
