如何在SqlKata中转换和优化此SQL查询

问题描述

我有这个SQL查询，我需要将其转换为sqlkata

    const routes: Routes = [
  { path: 'main',component: MainComponent },{ path: 'home',component: HomeComponent },{ path: 'Feeds',component: MyFeedsComponent },{ path: 'friends',component: FriendsComponent },{ path: 'public',component: PublicComponent }
];

我不知道如何构造它，因为这里是SELECT VVIAGGIO AS VIAGGIO,ISNULL(AEAN,'') AS EAN FROM SALDI V INNER JOIN ARTICOLI A ON VARTI=AARTI INNER JOIN ORDI OT ON vstaB=OTSTAB AND VMAGA=OTMAGA AND VAGG=OTRAGG WHERE VORDI ='21' AND VHOST ='68' ORDER BY VPROG,AARTI ，ISNULL()。 我已经检查了SqlKata选择说明。

关于如何在sqlkata中优化和转换此查询的任何建议？

解决方法

这是您需要的：

var query = new Query("SALDI as V")
    .Join("ARTICOLI as A","A.ARTI","V.ARTI")
    .Join("ORDI as OT",j => j.On("OT.STAB","V.STAB")
          .On("V.MAGA","OT.MAGA")
          .On("V.AGG","OT.RAGG")
    )
    .Where("V.ORDI","21")
    .Where("V.HOST","68")
    .Select("V.VIAGGIO")
    .SelectRaw("ISNULL(V.AEAN,'') as EAN")
    .OrderBy("V.PROG","A.ARTI")
