    It looks you are trying to run this on a windows system, which requires special treatment of directory separators.

    Try:

    SELECT * FROM lahore_student INTO OUTFILE 'b:\\uploaded\\data.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '".'"'."'
LINES TERMINATED BY '\n'

    Or:

    SELECT * FROM lahore_student INTO OUTFILE 'b:/uploaded/data.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '".'"'."'
LINES TERMINATED BY '\n'

    Also note that this will not overwrite an existing file (which is the error you are getting). So you need to make sure that any file with that name is deleted first.

    See the The “\” path name separator character section on this page in the MYSQL docs:
