 ( SELECT daily_id FROM  tb_pv_feedback_daily WHERE tb_pv_feedback_daily.id  = tb_publicvoice.id ) AS feedback_daily_id,
 ( SELECT COUNT (*) FROM tb_pv_comment WHERE  tb_pv_comment.id = tb_publicvoice.id ) AS comment_count,
 ( SELECT content FROM tb_pv_feedback WHERE tb_pv_feedback.id = tb_publicvoice.id AND tb_pv_feedback.type = 0) AS docFeedback,

有可能出现问题的,可以在这
( SELECT ( SELECT CAST (dispose_doc_no AS VARCHAR) + ',' FROM tb_pv_dispose WHERE tb_pv_dispose.id = tb_publicvoice.id  FOR xml path ('')) ) AS dispose_doc_no,
你把这个先去掉看看.
