如何用sqlload导字段类型是number的

Posted 2023-04-23

参考技术A load data
infile 'result.csv '
into table resultxt
(resultid number load data
infile 'result.csv '
into table resultxt
(resultid number terminated by ', ',
website char terminated by ', ',
ipport char terminated by ', ',
status char terminated by whitespace)
直接在ctl文件里面的字段后面标上number即可，否则自动转为Char。追问

这样写问什么报错啊SQL*Loader-350: Syntax error at line 13.
Expecting valid column specification, "," or ")", found "number".
card_type number terminated by ', ',

追答

load data
infile 'result.csv '
into table resultxt
(resultid number load data
infile 'result.csv '
into table resultxt
FIELDS TERMINATED BY ','
(resultid number , website char ,ipport char , status char )
使用这个格式试一试

本回答被提问者采纳 参考技术B 你先查询数据类型为number的，语句如下，你参考参考：
SELECT syscolumns.name FROM sysobjects INNER JOIN
syscolumns ON sysobjects.id = syscolumns.id INNER JOIN
systypes ON syscolumns.xtype = systypes.xtype where systypes.name ='number'
and sysobjects.name = '表名'
--如果还要模糊查询字段名，加上下面代码
-- and syscolumns.name like '%字段%'

如何用ORM自定义排序

ORM连接的数据库不同，方法也不同

postgresql:

a.extra(select="new_order":"position(status in ‘2,3,4,1‘)").order_by("new_order")

a是queryset对象，new_order 是新的自定义的字段名，status是排序的字段，“2，3，4，1”是你自定义的顺序，也可以是字符串类型

mysql:

a.extra(select="new_order":‘field(status,"2,3,4,1")‘).order_by("new_order")

规则类似，但有所区别，这是我自己探索出来的，希望对大家有所帮助
