Lambda表达式或LINQ中的子查询

Question

你如何使用lambda表达式或LINQ编写此查询：

SELECT    *
FROM      vehicles 
WHERE     (memo1 like '%CERTIFIED%' OR memo2 = 'CERTIFIED')
AND       stockno IN (SELECT stockno FROM udealer2 where ACC='UCERT')
ORDER BY  model, days DESC

Answer 1

不了解您的模型情况，这里是您查询的机械翻译：

vehicles.Where( v =>
    (SqlMethods.Like(v.memo1, "%CERTIFIED%") || v.memo2 == "CERTIFIED") &&
    udealer2.Any(d => d.ACC == "UCERT" && d.stockno == v.stockno)
).OrderBy(v => v.model)
.ThenByDescending(v => v.days)
