语法错误,建议找到对应的 SQL(程序或 tidb- server 日志里,应该有记录)

用mysql5.7正常,换TIDB5.0.1后,执行方法报错

格式化失败,在navicat连TIDB执行正常

    select gg.SCGG_TYWYSBM as id, SC_TYWYSBM as materialId, SCPP_TYWYSBM as brandId, SCPP_MC as brandName,
    JLDLDW as unit, d1.ZDMC as normName, GG_SZ as normNum, GG_DW as normUnit, d2.ZDMC as normUnitName,
    BZZL_SZ as standWeight, gg.JG_TYWYSBM as orgId
    from hs_sc_gg gg
    left join sys_dict d1 on d1.ZDM = 'canMaterialUnit' and gg.JLDLDW = d1.ZDZ
    left join sys_dict d2 on d2.ZDM = 'normUnit' and gg.GG_DW = d2.ZDZ
    where gg.SCBS = '0' and gg.SC_TYWYSBM = #{materialId}
    and (((gg.JG_TYWYSBM is null or gg.JG_TYWYSBM = '') and JLDLDW in ('1','99')) or gg.JG_TYWYSBM = #{orgId})
    order by gg.JG_TYWYSBM, gg.SCPP_TYWYSBM

:ok_hand:

语法在库里执行是没问题的,怎么能知道转换失败是什么原因呢?从mysql5.7切过来后由很多这样的报错

表结构
hs_sc_gg.sql (4.0 KB)

这个报错和上面说的 SQL 语句没关系吧(建议你打开 general log ,看看报错的这个连接是那个程序链接过来的,看看 SQL语句: SAVEPOINT SAVEPOINT_1 是怎么生成的

你程序用的什么框架?以前版本不报错吗(tidb 不支持 savepoint 的)(建议你确认一下程序是否有变动/新上线之类)

是这个页面吗,程序是springboot2+mybatis-plus,以前用的mysql5.7没问题,刚迁移过来发现的问题

额,你是刚从 mysql 迁移到 tidb 啊,tidb 不支持 savepoint 语法的,https://docs.pingcap.com/zh/tidb/dev/mysql-compatibility#不支持的功能特性

已解决,是service里@Transactional(propagation = Propagation.NESTED, isolation = Isolation.DEFAULT, rollbackFor = Exception.class)标签的问题

:joy:学习一下,你上面的是什么的配置》?

service里面事务的配置

:ok_hand:我查一下
