how i can do these steps in stored proceedure
1)load all record
2)loop all records and check number of matching charactes

Using looping / cursoring in SQLServer , is very much frowned upon as its slow.
*Sometimes* its the only way to do things but not here.
Is it a single character that you need to count ? You could use replace to replace the character with a blank ie '' and count the string lengths before and after.
If multiple characters , use a tally table to split the string ala http://qa.sqlservercentral.com/articles/T-SQL/62867/ and simply use the count aggregate.

This requirement is not very clear. If you are just looking for columns wider than a certain number, use something like this:
select *
from table
where len(columnName) > 20
If that is not what you want, please provide some sample data, and example searches to clarify the requirement.

Ok let me check your code.
Actually my case is....
i have a table have thousands of data about company and people do search for any company.
i want to provide related/suggested search to people as if a user type uncorrect/misspell company name so i will show all those names having more matched characters he/she entered...just like google search do...by "DId you mean" etc etc

you could try and use the SOUNDEX function in T-sql and do this without a loop/cursors

Actually i want to provide options to users regarding their search .....
Eg if some one write "str" i want to show him "star" OR "sstr" mean nearly matching my db field world
just like google search do

to get the anywhere near the sort of functionality that google has, then you will probably need to do some coding in an application langauge such as c# or Python or whatever.
here is a good article on how to have a 'google' like search.

And here is a soundex example.
;with tempData as
(select 'star' Company union select 'stir' union select 'My Fab Company')
select company from tempData
where soundex(company) like soundex('str')

1) You won't. I was using a CTE as a way of generating sample data. You should use your source table. I used a CTE as a way of creating a query which will run without a database - just load into SSMS and execute.
2) As above - just sample data - a combination of yours and mine.

Hmm, not 100% sure what you mean. Maybe something like this:
select 'Company' FieldName,
len(COMPANY) - len(replace(COMPANY, 'piz', '')) as numberofoccurences
from vwSearchResult
union
select 'F1',
len(F1) - len(replace(F1, 'piz', ''))
from vwSearchResult
order by numberofoccurences desc
Replace F1 with the name of the field you wish to check.
