SQL查詢中的LINQ

Question

。由於從客戶奇怪的要求翻譯，我設法弄清楚如何使用SQL查詢來實現它 ，但我不能把它翻譯成LINQ的支持。

SELECT (SELECT count(*) FROM table1 where attribute1 like 'value1'), 
     (SELECT count(*) FROM table2 where attribute2 like 'value2') 

什麼翻譯查詢到LinQ？

Answer 1

你可以只提供一個謂詞的Count()功能

var result = new { 
      Count1 = table1.Count(r => r.attribute1.Contains("value1")), 
      Count2 = table2.Count(r => r.attribute2.Contains("value2")) 
     }; 

Answer 2

var count1 = (from i in table1 where SqlMethods.Like(i.attribute1, "value1") select i).Count(); 
var count2 = (from i in table2 where SqlMethods.Like(i.attribute2, "value2") select i).Count();
