Question

我正在尝试进行下一个选择：

ArrayList<Personal> personalAuxList = new ArrayList<Personal>()
def campaigns = Campaign.findAllByEntidad(entidadInstance,[sort: "fechaFin", order: "desc"])
//Here a declare a DetachedCriteria using where method of domain class
def notificacionesQuery = Notificacion.where {
    orden.linea.propuesta.campaign in campaigns
}
//For each persona from a search result done before     
for(Personal person : result.results){
    if(!personalAuxList.contains(person)){
        //I add a condition to query creating new one
        def notisOfPersonalQuery = notificacionesQuery.where {
            personal == person
        }
        //Fail in this line when i list the result
        def notificaciones = notisOfPersonalQuery.list()
        notificaciones = notificaciones.sort{it.orden.linea.fin}.reverse()
        notisOfPersonal.put(person.id, notificaciones.empty ? null : notificaciones.first())
        personalAuxList.add(person)
    }
}

在本地工作正常，但是当我上传战争时，开始在服务器中失败：

类： com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException

消息：您的SQL语法出错;检查与MySQL服务器版本对应的手册，以便在第1行附近使用正确的语法，并在第1行使用this_.personal_id = 6616'

我最终解决了，在本地我在DDBB中获得了广告系列，但是在真实服务器上没有，所以如果没有广告系列，我会更改代码以添加条件：

ArrayList<Personal> personalAuxList = new ArrayList<Personal>()
def campaigns = Campaign.findAllByEntidad(entidadInstance,[sort: "fechaFin", order: "desc"])
if (campaigns != null && campaigns.size() > 0) {
    def notificacionesQuery = Notificacion.where {
        orden.linea.propuesta.campaign in campaigns
    } 
    for(Personal person : result.results){
        if(!personalAuxList.contains(person)){
            def notisOfPersonalQuery = notificacionesQuery.where {
                personal == person
            }
            def notificaciones = notisOfPersonalQuery.list()
            notificaciones = notificaciones.sort{it.orden.linea.fin}.reverse()
            notisOfPersonal.put(person.id, notificaciones.empty ? null : notificaciones.first())
            personalAuxList.add(person)
        }
    }
}

Grails DetachedCriteria使用'where'抛出SyntaxErrorException
