先定义了一个数组,在LINQ to SQL中使用Contains,数组中包含了所有的CustomerID,即返回结果中,所有的CustomerID都在这个集合内。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).ToLis...
在进行不区分大小写的and_查询时,可以使用SQLAlchemy的func.lower()函数将字段和查询字符串都转换为小写,然后再进行比较。这样就可以忽略大小写进行查询。 下面是一个示例代码: 代码语言:txt 复制 from sqlalchemy import create_engine, Column, Integer, String, func from sqlalchemy.orm import sessionmake...
contains方法用于判断指定系列是否包含指定字符串。类似于 SQL 中的 like 函数,实现模糊匹配。 str将Series转换为类似于String的结构。 返回布尔值系列或索引,具体取决于给定模式或正则表达式是否包含在系列或索引的字符串中。 使用语法 Series.str.contains(pat, case=True, flags=0, na=None, regex=True) ...
string[] customerID_Set = new string[] { "AROUT", "BOLID", "FISSA" }; var q = ( from o in db.Orders where customerID_Set.Contains(o.CustomerID) select o).ToList (); 语句描述:查找"AROUT", "BOLID" 和 "FISSA" 这三个客户的订单。先定义了一个数组,在LINQ to SQL中 使用Contains,...
wherename in ('frame') The problem is the filter does first break name into word before comparing to “frame.” Luckily there is a SQL function that addresses this issue. To get around this dilemma we’ll use STRING_SPLIT(). Unlike other functions, which output a single value,STRING_SPLI...
The position() function is also a good alternative to find if the string contains a substring or not. The basic syntax of this function is given as SELECT POSITION(Sub_string IN String); The function returns the number that shows the location of the substring in the string, 0 if the sub...
SQLคัดลอก CONTAINS(column_name, 'NEAR(term1,"term3 term4")') The optional parameters are as follows: <maximum_distance> Specifies the maximum distance allowed between the search terms at the start and end of a string in order for that string to qualify as a match. ...
