wordpress回收站在哪里,计算机培训机构排名最新,怎么把自己做的网站登录到网上,wordpress 使用技巧如图#xff0c;sql语句在数据库里可以正常运行但是再XML文件不可以正常运行#xff0c;报错。
原因#xff1a;在XML中小于号是会被默认认定成文一个标签的开始#xff0c;所以用小于号就会报错。
解决办法#xff1a;
1.把表达式反过来改成大于号

2.用![CDATA[ ]]包起来就不会被认定成为标签 ![CDATA[ AND (stt.class_date stt.class_start_time::interval CURRENT_TIMESTAMP OR (stt.class_date CURRENT_DATE AND stt.class_start_time 00:00:00::time)) ]] 在这里我就展示一下用![CDATA[ ]]包起来的写法 SELECT stt.id,stt.class_date,stt.class_start_time,stt.class_end_time, (SELECT COUNT(*) FROM study_time_table_study_student sttss2 WHERE sttss2.study_time_table_id stt.id AND sttss2.used_status 1) AS actual_num, -- stt.actual_num, htm.teacher_name,htm.id as teacher_name_id, tcm.class_name,tcm.class_type,tcoum.course_name,tcoum.id as course_name_id,stt.study_course_id, sttss.study_student_id as student_id,ss.sts_student_name,ss.sts_phone FROM study_time_table stt JOIN teach_class_manage tcm ON tcm.id stt.study_class_id JOIN teach_course_manage tcoum ON tcoum.id stt.study_course_id JOIN hr_teacher_manage htm ON htm.id stt.hr_teacher_id LEFT JOIN study_time_table_study_student sttss ON stt.id sttss.study_time_table_id JOIN study_student ss ON ss.id sttss.study_student_id where 11 AND stt.deleted 0 AND sttss.used_status 0 ![CDATA[ AND (stt.class_date stt.class_start_time::interval CURRENT_TIMESTAMP OR (stt.class_date CURRENT_DATE AND stt.class_start_time 00:00:00::time)) ]]
