我得到以下
select p.*, (select paypal_status from tbl_order as o where paypal_status = 'paid' and end_time > now() and p.post_id = o.post_id) as sort_post from tbl_postad as p where post_category in ('1','7','14','20','26','32','38','44','50','56','62','68','74','80','97','140','144','150','177','179','235','259','284','298','334','370','397','410','429','450','467','479','495','522','535','543') and post_expiredate >= '2018-07-25 13:00:18' and post_delete_status!='Y' and post_cat_status!='N' and block = 0 and post_country = "India" and post_status = 'Y' order by post_date desc LIMIT 0, 15
您的SQL语法有错误；检查手册 对应于您的MySQL服务器版本以使用正确的语法 在“ post_category”附近 （'1'，'7'，'14'，'20'，'26'，'32'，'38'，'44'，'50'，'56'，'62'，'68'，' 74英寸 第1行
查询在phpmyadmin中正确执行：
select p.*, (select paypal_status from tbl_order as o where paypal_status = 'paid' and end_time > now() and p.post_id = o.post_id) as sort_post from tbl_postad as p where post_category in ('1','7','14','20','26','32','38','44','50','56','62','68','74','80','97','140','144','150','177','179','235','259','284','298','334','370','397','410','429','450','467','479','495','522','535','543') and post_expiredate >= '2018-07-25 13:00:18' and post_delete_status!='Y' and post_cat_status!='N' and block = 0 and post_country = "India" and post_status = 'Y' order by post_date desc LIMIT 0, 15
即使最短的查询也会返回错误：
select p.*, (select paypal_status from tbl_order as o where paypal_status = 'paid' and end_time > now() and p.post_id = o.post_id) as sort_post from tbl_postad as p where post_status='Y' order by post_date desc LIMIT 0, 15
您的SQL语法有错误；检查手册 对应于您的MySQL服务器版本以使用正确的语法 在第1行的'post_status ='Y''附近
我的PHP版本：PHP版本5.6.36
