凡在实体framwork

Question

选择我想要写SQL命令的实体查询：

SELECT * FROM provider WHERE serial 
     NOT IN (SELECT providerRef as Serial FROM ProviderTeam WHERE TeamRef=134) 

我在网上搜索，但没有答案。

Answer 1

你可以重写你的IN子句EXISTS和使用下面的命令LINQ：

var q = from p in dbContext.Providers 
     where !dbContext.ProviderTeams.Any(pt => pt.TeamRef == 134 && pt.providerRef == p.serial) 
     select p; 

Answer 2

我希望这是你所需要的：

using (var dbObj = new [DB_NAME]Entities()) 
{ 
    var list = dbObj.provider.SqlQuery("SELECT * from provider where serila NOT IN (select providerRef as Serial from ProviderTeam where TeamRef=134)").ToList(); 
}
