请教各位这个到底是什么问题啊，用的是springboot+mybatisplus整合，怎么select count()括号中是空呢
这是报错信息：
Cause: java.sql.SQLSyntaxErrorException: 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 ') FROM user_info' at line 1
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: 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 ') FROM user_info' at line 1
