The problem is that you are storing the output of mysql into an array. Now, if mysql returns multiple records you won't know when a record ends and the next one starts because the array will contain the "flattened" data e.g. ( record1_fieldA record1_fieldB record2_fieldA record2_fieldB ... )

Instead, use a while loop to iterate over the records like this:

i=0
while read fieldA fieldB
do
    echo "Record $(( i++ )): fieldA: $fieldA fieldB: $fieldB"
done < <(mysql --user root -proot test -Bse "select id,name from Object")
