Well, I think I found something.
Don't really know why it works, just tried several possibilities.
Code:
MYSQL="mysql -u user -ppassword database"
TAB=$(echo -e "\t")

{ IFS="$TAB" read a b c; } <<< "$($MYSQL -Ne "SELECT id, nom, is_master FROM terminal WHERE id = 4")"
echo "$a-$b-$c"

{ IFS="$TAB" read a b c; } <<< "$($MYSQL -Ne "SELECT id, nom, is_master FROM terminal WHERE id = 14")"
echo "$a-$b-$c"

install-datebook(1)					      General Commands Manual					       install-datebook(1)

NAME
install-datebook - installs a new datebook entries onto your Palm handheld device SYNOPSIS
For serial devices, the -p <port> option is required, or you may use the $PILOTPORT environment variable: install-datebook -p /dev/ttySX filename [filename filename ...] For USB devices, the new USB port specification is: install-datebook -p usb:/dev/ttyUSBX filename [filename filename ...] DESCRIPTION
install-datebook allows the user to write one or more datebook entries from one or more source files. Once install-datebook is started, the user must invoke HotSync on the target device by pressing the HotSync button on the cradle or by tapping on the HotSync icon in the Palm launcher. The format of the source file contains one datebook entry on line, containing four tab separated fields. The fields are start date/time, end date/time, alarm settings, and the description of datebook entry. This program doesn't yet support repeted entries. The date and time must be in format understand by parsedate.y. At the very least, the following two formats are understood: August 11, 1997 0800 GMT+300 1997/08/11 08:22:33 GMT+300 If either one of the date and time fields is empty, the entry is installed without time. If the alarm field is empty, the entry is installed without setting any alarms. The alarm field can contain numbers followed by "m" (minutes), "h" (hours), or "d" (days). Here are some example lines ("<TAB>" = tab, "<NL>" = newline in these examples): -> 1997/08/11 0800 GMT+300 <TAB> 1997/08/11 0900 GMT+300 <TAB> <TAB> IETF Registration <NL> -> August 11, 1997 0900 GMT+300 <TAB> August 11, 1997 0930 GMT+300 <TAB> 2m <TAB> Introductions <NL> OPTIONS none USAGE
The program will connect to the target Palm device, and write the datebook-formatted file given on the command line onto the Palm into the DatebookDB.pdb file. KNOWN BUGS
If no timezone is given, install-datebook will assume the time is in GMT and it will convert it to localtime. If you don't want to write timezone entries to all begin and end times, set the TZ environment variable to GMT before running this program. REPORTING BUGS
