MySQL中的子字符串

Question

我试图在MySQL表中插入一个字符串.但以下不是我要找的.

select substring_index('3|5|6|asdf asd|6|0|NULL', '|', 1) as first,
substring_index('3|5|6|asdf asd|6|0|NULL', '|', 2) as second,
substring_index('3|5|6|asdf asd|6|0|NULL', '|', 3) as third,
substring_index('3|5|6|asdf asd|6|0|NULL', '|', 4) as forth,
substring_index('3|5|6|asdf asd|6|0|NULL', '|', 5) as fifth

+-------+--------+-------+----------------+------------------+
| first | second | third | forth          | fifth            |
+-------+--------+-------+----------------+------------------+
| 3     | 3|5    | 3|5|6 | 3|5|6|asdf asd | 3|5|6|asdf asd|6 | 
+-------+--------+-------+----------------+------------------

+

我希望5作为秒,6作为第三,'asdf asd'作为第四列.在MySQL中有可能吗？

Answer 1

substring_index(substring_index('3|5|6|asdf asd|6|0|NULL', '|', 2), '|', -1)

给出5

substring_index(substring_index('3|5|6|asdf asd|6|0|NULL', '|', 3), '|', -1)

给出6

等等
