Word specific search in asp using c# for auto-complete

Question

I have a column in sql called "Name", it has these values:

abhay kumar
rajesh saaw
anjan raj
gopal murti
pravat saha

Now I want sql code that will return only words containing "r".

So in this query, it should return:

kumar, rajesh, raj, murti, pravat

and not :

abhay, anjan, gopal, saha.

Answer 1

The SQL LIKE operator should do the job. You can compare against text pattern using the following SQL command form:

SELECT ... WHERE Name LIKE '%r%';

For example:

SELECT Name FROM Person WHERE Name LIKE '%r%';

The % is a wildcard that represents various count of various characters (similarly to * in filenames). So %r% means any string that contains the letter r .

Answer 2

我不确定如何在C＃中连接数据，但是如果您使用linq，我将建议以下内容（尽管我对数据访问层做了很多假设）：

ctx.User.All(u => u.Contains("r"));
