IN (item1,item2[...,itemn]),IN (subquery) - 一个等式条件,它将字段值与逗号分隔列表中的任何项或子查询返回的任何项匹配。 %INLIST listfield - 将字段值与%List结构化列表中的任何元素匹配的相等条件。 [ - 包含运算符。 Match必须包含指定的字符串。 Contains操作符使用EXAC
questionnaireAnswersPageRequest.CollectionOfAnswers.Contains(td.WjTmDaId)).Any()); 比如这个子查询中的 && questionnaireAnswersPageRequest.CollectionOfQuestions.Contains(td.WjTmId) && questionnaireAnswersPageRequest.CollectionOfAnswers.Contains(td.WjTmDaId)).Any()); 根据数组list生成多个WjTmId==1 and WjT...
也就是in。 你也可以把数组的定义放在LINQ to SQL语句里。比如: varq =(fromoindb.Orderswhere(newstring[] {"AROUT","BOLID","FISSA"}) .Contains(o.CustomerID)selecto).ToList(); Not Contains则取反: varq =(fromoindb.Orderswhere!(newstring[] {"AROUT","BOLID","FISSA"}) .Contains(o.Cus...
new string[] { "AROUT", "BOLID", "FISSA" }) .Contains(o.CustomerID) select o).ToList(); 1.包含一个对象: var order = (from o in db.Orders where o.OrderID == 10248 select o).First(); var q = db.Customers.Where(p => p.Orders.Contains(order)).ToList(); foreach (var cu...

SQL Server includes a standard list of noise words in the directory \Mssql\Binn\FTERef of each instance of SQL Server. Punctuation is ignored. Therefore, CONTAINS(testing, "computer failure") matches a row with the value, "Where is my computer? Failure to find it would be expensive." ...

我们继续讲解LINQ to SQL语句,这篇我们来讨论Group By/Having操作符和Exists/In/Any/All/Contains操作符。 Group By/Having操作符 适用场景:分组数据,为我们查找数据缩小范围。 说明:分配并返回对传入参数进行分组操作后的可枚举对象。分组;延迟 1.简单形式: ...
