Group no. of records by text in a text/varchar field

Create table Test
(Text1 varchar(500))
insert Test values('I love SQL')
insert Test values('SQL rocks')
insert Test values('SQL rocks in 2005')
insert Test values('MS rocks too')
insert Test values('MS is short for microsoft')
So i want to run a query where I would like to group by some key text words
..
So i want to get a count of entries in the table that has words 'SQL' and
'MS' in it
Output should be
KeyWord Count
MS 2
SQL 3
What is the query ? I would eventually add more keywords to the query..
Thanksyou'd want to unpack your input string into a table then it's just a matter
of finding the occurrences.
e.g.
declare @.s varchar(100)
set @.s='MS,SQL'
declare @.padded varchar(8000);set @.padded=','+@.s+','
select s,count(*)
from (select
substring(@.padded,digit+1,charindex(',',
@.padded,digit+1)-digit-1)
from racdigits
where digit <= len(@.padded)-1
and substring(@.padded,digit,1)= ',') derived(s)
join Test on Test.Text1 like '%'+derived.s+'%'
group by s
racdigits is just an auxilary table with value from 1-8000 (i.e. select top
8000 digit=identity(int,1,1) into racdigits from sysobjects,syscolumns)

If you use front end application, split data there

Hi Hassan,
Store the keywords in a seperate table, then use a query such as this:
SELECT k.Keyword, COUNT(t.Text1)
FROM Keywords AS k
LEFT JOIN Test AS t
ON t.Text1 LIKE '%' + k.Keyword + '%'
GROUP BY k.Keyword
