Self-referencing left join

Hi

I'm trying to convert the following sql into valid server DT code but I'm struggling a bit translating the aliases and embedded select statement in the left join.

• Here's the sql:

SELECT V.ID, ISNULL(V.CustomerIndex, C.CustomerIndex) as CustomerIndex

FROM GlobalPriceLists as V

LEFT JOIN (SELECT CustomerIndex, ListType, ListName FROM GlobalPriceLists WHERE CustomerIndex = 0) as C

ON C.ListType = V.ListType AND C.ListName = V.ListName AND V.CustomerIndex = 1

• Server code so far:

editor = new Editor(db, "GlobalPriceLists", "GlobalPriceLists.id")
.Model<CustomerSNsDBModel.GlobalPriceLists>("GlobalPriceLists");
editor.Field(new Field("GlobalPriceLists.id")
.Set(false)
);
editor.MJoin(new MJoin("GlobalPriceLists")
.Model<PriceListsDBModel>()
.Name("GlobalPriceLists.CustomerIndex")
.Link("GlobalPriceLists.ListType", "GlobalPriceLists.ListType")
.Link("GlobalPriceLists.ListName", "GlobalPriceLists.ListName")
.Where(q =>
q.Where("GlobalPriceLists.CustomerIndex", lngCustIdx, "=")
)
.Order("GlobalPriceLists.id ASC")
.Field(new Field("id")
.Options(new Options()
.Table("GlobalPriceLists")
.Value("id")
.Label("CustomerIndex")
)
.Set(false)
)
.Set(false)
);
editor.Field(new Field("GlobalPriceLists.ListType")
.GetFormatter((val, data) => CommonUtilities.IsNullOrEmpty(val) == true ? 0 : val)
);
editor.Field(new Field("GlobalPriceLists.ListName")
.GetFormatter((val, data) => CommonUtilities.IsNullOrEmpty(val) == true ? string.Empty : val)
);
editor.LeftJoin("GlobalPriceLists AS C", "GlobalPriceLists.id", "=", "GlobalPriceLists.SubPackID");
editor.Where("GlobalPriceLists.CustomerIndex", 0);
editor.Debug(true);
editor.Process(formData);

Thanks a lot.
