直接用dateTimeToString(M_bianjia.BJ10)看看

直接用dateTimeToString(M_bianjia.BJ10)看看

也不管，我想要截取BJ10这个字段，因为平台datetime类型的数据保存到sql里带毫秒，如2018-01-10 17:42:20.277，有什么办法可以保存时候不带毫秒也行

jishuang

默认存的没有啊

可以用SQL.调用数据库的函数实现截取

yangodman

我是ontology里面加的currentDateTime()默认值，保存的时候数据库里面是带毫秒的 ，其他input时间框赋值的datetime类型的字段也是这样，平台版本3.6，数据库是sql r2

jishuang

可以看看数据库中是否有日期格式的设置

ksql函数报错，可以用SQL.调用数据库的函数实现截取看看

yangodman

数据库表是用平台生成的，检查过没有设置格式；
group by之后用sql.、ksql函数都会报错；
像sql中select count(*) from M_bianjia group by M_bianjia.BJ3,M_bianjia.BJ4,M_bianjia.BJ9,CONVERT(varchar(19),M_bianjia.BJ10,120) 这种语句ksql该怎么写

jishuang

SQL.数据库函数报什么错？
