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.

udm_find

UDM_FIND(3)								 1							       UDM_FIND(3)

udm_find - Perform search

SYNOPSIS

       resource udm_find (resource  $agent, string  $query)

DESCRIPTION

	Performs a search.

	The search itself. The first argument - session, the next one - query itself. To find something just type words you want to find and press
       SUBMIT button. For example, "mysql odbc". You should not use quotes " in query, they are written here only to divide  a	query  from  other
       text.  mnoGoSearch  will find all documents that contain word "mysql" and/or word "odbc". Best documents having bigger weights will be dis-
       played first. If you use search mode ALL, search will return documents that contain both (or more) words you entered. In case you use  mode
       ANY,  the  search  will	return	list of documents that contain any of the words you entered. If you want more advanced results you may use
       query language. You should select "bool" match mode in the search from.

PARAMETERS

	      o $agent
		- A link to Agent, received after call to udm_alloc_agent(3).

	      o $query
		- mnoGoSearch understands the following boolean operators:  & - logical AND. For example, "mysql & odbc".  mnoGoSearch	will  find
		any  URLs  that  contain  both "mysql" and "odbc".  | - logical OR. For example "mysql|odbc". mnoGoSearch will find any URLs, that
		contain word "mysql" or word "odbc".  ~ - logical NOT. For example "mysql & ~odbc". mnoGoSearch will find URLs that  contain  word
		"mysql"  and  do  not  contain word "odbc" at the same time. Note that ~ just excludes given word from results. Query "~odbc" will
		find nothing!  () - group command to compose more complex queries. For example "(mysql | msql) &  ~postgres".  Query  language	is
		simple and powerful at the same time. Just consider query as usual boolean expression.

RETURN VALUES

	Returns a result link identifier on success or FALSE on failure.
