Useful example: return an array from function

function Query() {
  local _tmp=`echo -n "$*" | mysql 2>> zz.err`;
  echo -e "$_tmp";
}

function StrToArray() {
  IFS=$'\t'; set $1; for item; do echo $item; done; IFS=$oIFS;
}

sql="SELECT codi, bloc, requisit FROM requisits ORDER BY codi";
qry=$(Query $sql0);
IFS=$'\n';
for row in $qry; do
  r=( $(StrToArray $row) );
  echo ${r[0]} - ${r[1]} - ${r[2]};
done
