Group_concat 还是不支持吗?已经3.4.2.2 版本了

taos> select server_version();

server_version() |

3.4.2.2.community |
Query OK, 1 row(s) in set (0.000860s)

SELECT b,count(1) ,GROUP_CONCAT(distinct c) FROM
t1 WHERE a not in (xx)
and sendts >= ‘2026-08-04 03:20:23’ AND sendts <= ‘2026-08-07 03:20:23’
and sendtm >= ‘2026-08-07 03:15:23’ AND sendtm < ‘2026-08-07 03:20:23’ GROUP BY b;
还是报错
DB error: Invalid parameter data type : group_concat [0x80002802] (0.001134s)
