我有这样的查询:
SELECT GROUP_CONCAT(urut SEPARATOR '; ') AS urut
FROM pipe a
GROUP BY a.seal;
然后我得到:
记录1:
+-------------------------------------+
| 1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11; |
| 12; 13; 14; 15; 16; 17; 18; 19; 20; |
| 21; 22; 23; 24; 25; 26; 27; 28; 29; |

是否有一个函数可以使输出像
一样短+------+
| 1-44 |
|45-88 |
+------+
请告知
答案 0 :(得分:2)
您可以使用
自行构建SELECT CONCAT(MIN(urut), '-', MAX(urut)) AS urut
FROM pipe a
GROUP BY a.seal;
