Question

有人可以指导我将下面的SQL查询格式化为以下格式打印吗？

------------------------
COUNT_NAME | COUNT_VAL |
------------------------
COUNT_A    | 1         | 
COUNT_B    | 2         |  
COUNT_C    | 3         |  
COUNT_D    | 4         |
------------------------

以下查询以下列格式返回输出

--------------------------------
COUNT_A|COUNT_B|COUNT_C|COUNT_D|
--------------------------------
1      |2      |3      |4
--------------------------------
