DELETE FROM bdxm_person_info WHERE id>46171
提示错误信息：[SQL]DELETE FROM bdxm_person_info b WHERE b.id>46171
[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'b WHERE b.id>46171' at line 1
分析：经查询官网文档使用正确方法
结果：更为：DELETE b FROM bdxm_person_info b WHERE b.id>46170
总结：
删除使用别名语法：delete <alias> from <table> <alias> where <alias>.<field>...
mysql 5.7使用别名问题
