nhibernate删除带有引用的批处理
termInfo类nhibernate删除带有引用的批处理,nhibernate,hql,Nhibernate,Hql,termInfo类 public class TermInfo { public TermInfo() { this.Breviary = string.Empty; this.CreateBy = string.Empty; this.CreateDate = DateTime.Now; this.Group = 0; this.Name = string.Empty; } pub
public class TermInfo
{
public TermInfo()
{
this.Breviary = string.Empty;
this.CreateBy = string.Empty;
this.CreateDate = DateTime.Now;
this.Group = 0;
this.Name = string.Empty;
}
public override int GetHashCode()
public virtual int TermId { get; set; }
public virtual string Name { get; set; }
public virtual string Breviary { get; set; }
public virtual int Group { get; set; }
public virtual string CreateBy { get; set; }
public virtual DateTime CreateDate { get; set; }
public virtual IList<Taxonomy> Taxonomies { get; set; }
}
映射
internal class TaxonomyMap : ClassMap<Taxonomy>
{
public TaxonomyMap()
{
Table("Smart_TermTaxonomy");
Id(x=>x.TaxonomyId).GeneratedBy.Identity();
Map(x => x.Description);
Map(x => x.OrderId);
Map(x => x.ParentId);
Map(x => x.PostCount);
Map(x => x.TermTaxonomy).Column("Taxonomy");
References(x => x.Term, "TermId");
DynamicUpdate();
DynamicInsert();
}
}
internal class TermInfoMap : ClassMap<TermInfo>
{
public TermInfoMap()
{
Table("Smart_PostTerms");
Id(x=>x.TermId).GeneratedBy.Identity();
Map(x => x.Breviary);
Map(x => x.CreateBy);
Map(x => x.CreateDate);
Map(x => x.Group).Column("[Group]");
Map(x => x.Name).Column("[Name]");
HasMany<Taxonomy>(x => x.Taxonomies).KeyColumn("TermId");
}
}
我的问题是,如何按术语.Name删除分类法
我期望的sql是:
'从smart\u postTaxonomy中删除,其中termId=从中选择termId
smart_PostTerms,其中[Name]=@Name'
那么,我应该为此编写hql查询字符串什么呢?您是否尝试过在hql中执行类似的操作
session.CreateQuery(
"delete from Taxonomy t where t.Term.id = " +
" (select ti.id from TermInfo ti where ti.Name = :name)")
.SetParameter("name", termName)
.ExecuteUpdate();
您是否尝试过在HQL中执行类似的操作
session.CreateQuery(
"delete from Taxonomy t where t.Term.id = " +
" (select ti.id from TermInfo ti where ti.Name = :name)")
.SetParameter("name", termName)
.ExecuteUpdate();
