Question

Now this is tricky… I hope i can explain it well..

I have a a table which names in it and i need to compare it with the word i provide and get the exact match out..

Now i say it is tricky because i tried this query and it gave me a set of names. It contained the word which was an exact match and also words which were similar…

this is what i did:

DataTable dt = new DataTable();
        SqlConnection connection = new SqlConnection();
        connection.ConnectionString = ConfigurationManager.ConnectionStrings["xyz "].ConnectionString;
        connection.Open();
        SqlCommand sqlCmd = new SqlCommand("SELECT Names FROM Machines WHERE Name  Like '%' + @userName + '%'", connection);
        SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);

        sqlCmd.Parameters.AddWithValue("@userName", userName);

        sqlDa.Fill(dt);
        connection.Close();

Now what i want is… for example.

if the database has three words

abc123

xyz123

pqc1238

Now if the word is 123 it should
return abc123 and xyz123
if c123 then return abc123 and NOT pqc1238 and xyz123

if 238 then just return pqc1238….

I hope i was clear enough… trust me i did not get it the first time either

any suggestions are better to fingd the exact matches between words.. coz LIKE is not sufficient..

Thanks

To me, it looks like you are search for string ending with @userName.

SqlCommand sqlCmd = new SqlCommand("SELECT Names FROM Machines WHERE Name  Like '%' + @userName", connection);
