我使用
Insight.Database
作为我们的微型ORM.我想弄清楚是否有办法采用以下POCO类关联并将单行结果映射到这些对象中.
public class Rule
{
public int Id { get; set; }
public string Name { get; set; }
public RuleDetail Source { get; set; }
public RuleDetail Destination { get; set; }
}
public class RuleDetail
{
public int Id { get; set; }
public Name { get; set; }
public Date DateTime { get; set; }
// omitted...
}
这是从我们的存储过程返回的列:
Id
Name
// Should map to Source object.
SourceId
SourceName
SourceDateTime
// Should map to Destination object.
DestinationId
DestinationName
DestinationDateTime
最佳答案 这可以通过查询端的一些设置来实现.不确定属性是否可行.
var returns = Query.Returns(
new OneToOne<Rule, RuleDetail, RuleDetail>(
callback: (rule, source, destination) => {
rule.Source = source;
rule.Destination = destination;
},
columnOverride: new ColumnOverride[] {
new ColumnOverride<RuleDetail>("SourceId", "Id"),
new ColumnOverride<RuleDetail>("SourceName", "Name"),
new ColumnOverride<RuleDetail>("SourceDateTime", "DateTime"),
new ColumnOverride<RuleDetail>("DestinationId", "Id"),
new ColumnOverride<RuleDetail>("DestinationName", "Name"),
new ColumnOverride<RuleDetail>("DestinationDateTime", "DateTime"),
},
splitColumns: new Dictionary<Type, string>() {
{ typeof(Rule), "Id" },
{ typeof(RuleDetail), "SourceId" },
{ typeof(RuleDetail), "DestinationId" },
}
)
);
return Db.Query(procedure, params, returns);
我不确定是否需要所有代码来使其工作,但它肯定显示了Insight.Database中的查询功能有多强大.
