If your variables contain spaces and you want the array to have an element for each line of output (as opposed to each word of output), you also need to set your IFS. And you may want to use quotes when using the array:
如果您的变量包含空格并且您希望数组的每一行输出都有一个元素（而不是输出的每个单词），您还需要设置 IFS。并且您可能希望在使用数组时使用引号：
SaveIFS="$IFS"
IFS=$'\n'
array=( $(sqlplus [credentials] select variable from table;) )
echo "${array[*]}"
IFS="$SaveIFS"
