I have created a full text index on a column of a table. The issue is i need to search for AT&T.
the query i use for search is

SELECT * FROM TABLE_NAME WHERE CONTAINS(COLUMN_NAME, '"AT&T*"')

It returns many records but doesn't return the records with AT&T in it. I guess '&' is killing it, but i have no idea how to escape it in case of full text index search.
Any help will be deeply appreciated.

The '*' is killing you. Use '%' instead.

If you want to search for text that for example contains % or other special characters you have to escape them.
See the example below:

SELECT * FROM
(
SELECT UserName + '&%' + Email AS A FROM Employees
) G
WHERE G.A LIKE '%s&!%x%' ESCAPE '!'

I am concatenating two fields adding &% in between. No escaping needed there.
And I want to look for any record that has the literal pattern 's&%x' inside it

So in the LIKE however, I start with an '%s (the equivalent of *), follow with an 's', follow with an '&' (no escaping needed) and then I escape the '%' using any character I like, so I chose '!'. Then follows 'x' and '%' for the rest of the string.

Pretty straightforward right?

Keep in mind that this isn't standard T-SQL. It's Full Text Search.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
