使用如下 sql 查询不到

SELECT             U.USER_ID userId,             U.FULL_NAME fullName,             U.USER_NAME userName,             U.PASSWORD password,            
 U.ROLE_ID roleId,             U.COMPANY_ID companyId,             C.COMPANY_NAME companyName,             U.PHONE phone,             
U.EMAIL email,             C.COMPANY_ADDRESS companyAddress,             C.PRIMARY_AREA primaryArea,             U.STATUS status,             
U.CONFIGURE_SEND_STATUS configureSendStatus,             U.INVITE_CODE inviteCode,             U.CREATION_DATE creationDate,             
U.CREATED_BY createdBy,             U.LAST_UPDATE_DATE lastUpdateDate,             U.LAST_UPDATED_BY lastUpdatedBy,            
 R.ROLE_NAME roleName,             R.ROLE_TYPE roleType,             U.USER_TYPE userType,             U.PASSWORD_ERROR_COUNT passwordErrorCount, 
            U.PASSWORD_ERROR_DATE passwordErrorDate           FROM               USER U,               ROLE R,               COMPANY C           WHERE               
U.ROLE_ID = R.ROLE_ID           AND U.COMPANY_ID = C.COMPANY_ID           AND U.STATUS IN (1,2)           AND R.STATUS = 1           
AND U.USER_NAME = 'admin'           AND C.COMPANY_STATUS = 1

提示：
Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'chipsystem.USER' doesn't exist
表名修改为小写可以：

SELECT             U.USER_ID userId,             U.FULL_NAME fullName,             U.USER_NAME userName,             U.PASSWORD password,
