Suppose I have a table with following records

value                    text
company/about            about Us
company                  company
company/contactus        company contact

I have a very simple query in sql server as below. I am having problem with the 'or' condition. In below query, I am trying to find text for value 'company/about'. If it is not found, then only I want to run the other side of 'or'. The below query returns two records as below

value                       text
company/about               about Us
company                     company

Query

 select 
        *
    from 
        tbl
    where 
        value='company/about' or
         value=substring('company/about',0,charindex('/','company/about'))

How can I modify the query so the result set looks like

value                       text
company/about               about Us
