将 SQL 转换为 ServiceStack.ORMLite Sql 服务器

Question

如何将下面的SQL转成ServiceStack.OrmLiteSql服务器格式？

/* Total Receipts */
select convert(date, t.TransactionDate) [Date], tm.TeamId,a.AccountNumber, count(distinct(t.RequisitionNumber)) Total
from task.tblTransactions t
inner join task.tblRequisitions r on r.RequisitionNumber = t.RequisitionNumber
inner join task.tblAccounts a on a.AccountNumber = r.AccountNumber
inner join Team tm on tm.DivisionId = a.DivisionId
where t.TransactionTypeNumber = 201 and a.IsActive = 1 
and t.TransactionDate between @fromDate and @toDate
group by convert(date, t.TransactionDate), tm.TeamName, a.AccountName
order by 1,2 desc

我的结果class：

public class KpiTotal : IKpiTotal
{
    public DateTime Date { get; set; }

    public int TeamId { get; set; }
    public Team Team { get; set; }

    public int AccountId { get; set; }
    public Account Account { get; set; }

    public double Total { get; set; }
}

Answer 1

对于像这样的自定义 SQL，您可以使用 OrmLite 的自定义 SQL API，例如：

var results = db.Select<Poco>(@"select convert(date, t.TransactionDate) [Date], 
  tm.TeamName, a.AccountName, count(distinct(t.RequisitionNumber)) Total
  from task.tblTransactions t
  inner join task.tblRequisitions r on r.RequisitionNumber = t.RequisitionNumber
  inner join task.tblAccounts a on a.AccountNumber = r.AccountNumber
  inner join Team tm on tm.DivisionId = a.DivisionId
  where t.TransactionTypeNumber = 201 and a.IsActive = 1 
    and t.TransactionDate between @fromDate and @toDate
  group by convert(date, t.TransactionDate), tm.TeamName, a.AccountName
  order by 1,2 desc", new { fromDate = fromDate, toDate = toDate });

其中 fromDate 和 toDate 是您的参数化变量，Poco 是自定义类型，其字段与返回的结果集匹配。
