Answer 1

Instead of creating Stored Procedure You can create a shell or php script for the same

Example of a shell script that I usually use

#!/bin/bash

location="/home/abdul/Desktop"
user="root"
pass="root"
table="City"
database="world_innodb"

mysql -u$user -p$pass --column-names -e "SELECT * FROM $database.$table;" | sed 's/\t/"|"/g;s/^/"/;s/$/"/;s/\n//g' > $location/$table-$(date +"%Y-%m-%d").csv

This will create file name like City-2014-02-20.csv

Stored procedure to do the same

DROP PROCEDURE IF EXISTS ExportToCSV;

DELIMITER $$

CREATE PROCEDURE `ExportToCSV`()

    BEGIN
    SET @cur_date =  CURRENT_DATE();
    SET @path = "/tmp/";
    SET @table_name =  "City";

    SET @VarSQL = CONCAT('SELECT * INTO OUTFILE  \'' ,@path,@table_name,'-',@cur_date,'.csv\' FIELDS TERMINATED BY ''\,','\' OPTIONALLY ENCLOSED BY \'','"' ,'\' LINES TERMINATED BY \'','\\n','\' FROM ',@table_name,';' );

    PREPARE stmt FROM @VarSQL;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;

    END$$
