Oracle字符集AL32UTF8 改ZHS16GBK字符集

数据导入数据突然发现大量报错，字段长度不够

ORA-02374: conversion error loading table "ECM"."C_CAR_CARD"
ORA-12899: value too large for column CARD_MANUFACTURER (actual: 48, maximum: 32)

ORA-02372: data for row: CARD_MANUFACTURER : 0X'BBB9B9FEB9FEB9FEB9FEB9FEB9FEB9FEB9FEB9FEB9FEB9FEB9'
 

一看肯定字符长度不一致

验证两个库之间的字符

查看两边字符集

oracle server 端 字符集查询  select userenv('language') from dual  SQL> select userenv('language') from dual; USERENV('LANGUAGE') ---------------------------------------------------- AMERICAN_AMERICA.ZHS16GBK 目标端字符集默认AL32UTF8

特别对于汉子存放1个汉子存放占用长度不一致

 

数据已经导入小半，进行目标端删除操作

drop user username cascade;---递归删除

重新建立用户

create user 

grant xxx to

修改字符集

重新导入数据没有报错
