SELECT count(*) as t FROM `dr_1_image` WHERE `dr_1_image`.`status` = 9 AND `dr_1_image`.`catid`IN (2,9,10,11,12,13,14,15,16,17,18,19,24,25,26,27,28,29,30,31,32) AND ((`dr_1_image`.`guige`<>'' AND JSON_CONTAINS (`dr_1_image`.`guige`->'$[*]', '"29"', '$'))) AND (`dr_1_image`.`gongyi`=1) ORDER BY NULL

列表单如果是单选的点击访问是正常的，如果把字段换成复选框，点击就报错，请问是什么原因呢
