how to show data from a csv file on web page in tabular form

I am working on a system where i need to select millionsof records from
mysql and there is no key is defined on that table as there is mass
inserting and updating work simultaneously .
so i use this command to a genrate csv file from selected data and its
working for me in great way .
SELECT *
INTO OUTFILE 'E:\\31october\\SP\\Export\\xyz.csv'
FIELDS
TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\n'
FROM tblspmaster;
but my problem is i also have to update the selected records and needs to
show those records on aspx page . if i run select its just running and
running .
So I have two questions
1- How can i update another fields in that table using INTO OUTFILE of
mysql .
2- Is it possible that instead of showing records on web page from mysql
response i just use this csv file to bind my gridview ? or right custom
HTML ?
I know my question title is more related to second part but first part is
equally or you can say more important .
