bash mysql export to file
I'm trying to export a mysql query to a .csv file, right now I'm running a successful query like:
Code:
us_id=`mysql -u $USER_NAME --password=$PASSWORD -D "databasename" \
        -e "SELECT * \
        FROM databasename.table \
        WHERE somefield >0 AND otherfield ='$ctry' \
        ORDER BY users \
        DESC LIMIT 0,100";`

but I want to export it to a file, which I've tried by using:
Code:
us_id=`mysql -u $USER_NAME --password=$PASSWORD -D "databasename" \
        -e "SELECT * \
        FROM databasename.table \
        WHERE somefield >0 AND otherfield ='$ctry' \
        ORDER BY users \
        DESC LIMIT 0,100 TO OUTFILE 'somefile.csv' ";`

but then I get a db access denied error. I've also tried piping the output to sed ’s/\t/”,”/g;s/^/”/;s/$/”/;s/\n//g’, which also didn't work. If I could get TO OUTFILE to work I'd hopefully add this code to make the fields formatted:
Code:
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY ‘\\’ LINES TERMINATED BY '\n'

but I can't get the OUTFILE function to work. I could also use mysqldump I guess, but I don't know how to combine the query with a mysqldump. my output file exists and I chmod'ed it to 777 (for testing purposes).

---------- Post updated at 12:27 PM ---------- Previous update was at 10:10 AM ----------

got it, well really never got the TO OUTFILE working, but this worked:
Code:
echo "SELECT * \
        FROM somedb.sometable \
        WHERE field1 >0 AND field2 ='whatever' \
        ORDER BY field3 \
        DESC LIMIT 0,100 ;" > tmp
mysql -sN -u $USER_NAME --password=$PASSWORD -D "somedb" < tmp > temp_to_turn_into_csv_later.csv

now I have to parse the temp csv file into a csv using awk, there's probably an easier way though.

mysql_tzinfo_to_sql

MYSQL_TZINFO_TO_S(1)					       MySQL Database System					      MYSQL_TZINFO_TO_S(1)

NAME

       mysql_tzinfo_to_sql - load the time zone tables

SYNOPSIS

       mysql_tzinfo_to_sql arguments

DESCRIPTION

       The mysql_tzinfo_to_sql program loads the time zone tables in the mysql database. It is used on systems that have a zoneinfo database (the
       set of files describing time zones). Examples of such systems are Linux, FreeBSD, Solaris, and Mac OS X. One likely location for these
       files is the /usr/share/zoneinfo directory (/usr/share/lib/zoneinfo on Solaris). If your system does not have a zoneinfo database, you can
       use the downloadable package described in Section 10.6, "MySQL Server Time Zone Support".

       mysql_tzinfo_to_sql can be invoked several ways:

	   shell> mysql_tzinfo_to_sql tz_dir
	   shell> mysql_tzinfo_to_sql tz_file tz_name
	   shell> mysql_tzinfo_to_sql --leap tz_file

       For the first invocation syntax, pass the zoneinfo directory path name to mysql_tzinfo_to_sql and send the output into the mysql program.
       For example:

	   shell> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

       mysql_tzinfo_to_sql reads your system's time zone files and generates SQL statements from them.	mysql processes those statements to load
       the time zone tables.

       The second syntax causes mysql_tzinfo_to_sql to load a single time zone file tz_file that corresponds to a time zone name tz_name:

	   shell> mysql_tzinfo_to_sql tz_file tz_name | mysql -u root mysql

       If your time zone needs to account for leap seconds, invoke mysql_tzinfo_to_sql using the third syntax, which initializes the leap second
       information.  tz_file is the name of your time zone file:

	   shell> mysql_tzinfo_to_sql --leap tz_file | mysql -u root mysql

       After running mysql_tzinfo_to_sql, it is best to restart the server so that it does not continue to use any previously cached time zone
       data.
