您好:

    1. 请检查tikv,tidb,pd的版本是否都升级到了3.0.12, 使用实例安装服务器目录的/bin/tikv-server ,tidb-server,pd-server -V命令查看,多谢
    2. 请再尝试执行一下,保证没有中文符合等.  麻烦再反馈下结果,多谢
    3.  麻烦反馈表结构,多谢.

没有中文,因为表是空表,只是验证的,直接安装的版本可以,升级过来的版本报的这个错;

表结构如下: | b_major_bill | CREATE TABLE b_major_bill ( eid bigint(20) DEFAULT NULL, eitime datetime DEFAULT CURRENT_TIMESTAMP, eutime datetime DEFAULT CURRENT_TIMESTAMP, serverid bigint(20) DEFAULT NULL, fundid bigint(20) DEFAULT NULL, indexkey bigint(20) DEFAULT NULL, timeslot varchar(64) DEFAULT NULL, profitrate decimal(22,6) DEFAULT NULL, profit decimal(20,4) DEFAULT NULL, profitrankindex bigint(20) DEFAULT NULL, profitrankpercent decimal(20,4) DEFAULT NULL, remark varchar(200) DEFAULT NULL, gainrate decimal(20,4) DEFAULT NULL, maxgain decimal(20,4) DEFAULT NULL, maxloss decimal(20,4) DEFAULT NULL, maximum decimal(20,4) DEFAULT NULL, totalcount bigint(20) DEFAULT NULL, gaincount bigint(20) DEFAULT NULL, losscount bigint(20) DEFAULT NULL, avgposition decimal(20,4) DEFAULT NULL, bizdate bigint(20) DEFAULT NULL, volatility decimal(20,4) DEFAULT NULL, sharperatio decimal(20,4) DEFAULT NULL, tradecount bigint(20) DEFAULT NULL, buycount bigint(20) DEFAULT NULL, salecount bigint(20) DEFAULT NULL, gainamt decimal(20,4) DEFAULT NULL, lossamt decimal(20,4) DEFAULT NULL, UNIQUE KEY pk_lg_b_marjor_bill (fundid,indexkey,timeslot,serverid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin

麻烦在升级的集群上拿下 select *from information_schema.cluster_info 信息,感觉是 tidb 没升级成功,报错是报语法错误

我用ansible 升级的,提示是成功的; 没有这个系统视图 mysql> select * from information_schema.cluster_info; ERROR 1146 (42S02): Table ‘information_schema.cluster_info’ doesn’t exist

查了官方文档,没有这个表 information_schema.cluster_info

@Hacker_tn1kaAuv 抱歉,我记错了,那麻烦查下 select tidb_version();

有可能是升级上来的时候,默认关闭了 WIndowFunction 功能? 试一下 set tidb_enable_window_function = 1

内部复现了,的确是 set tidb_enable_window_function = 1 后就可以用了。

好吧,这块官方升级文档最有有个章节标注下,哪些功能会有调整和关闭;

你好,
