在Oracle数据库sqlplus命令行执行sql语句时，语句有中文报错解决

1.切换至oracle用户
2.使用sqlplus命令登录数据库
sqlplus 用户名@'数据库IP:端口/实例名
3.输入数据库用户、密码
4.查看当前数据库字符集
修改字符集：
1.直接修改服务器的字符集为AL32UTF8
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
2.重新连接数据库
sqlplus 用户名@'数据库IP:端口/实例名'
3.重新复制要执行的sql语句执行
4.查询数据库表创建情况及表结构
select * from T_ADEV_SCLG_YXDXMB;desc T_ADEV_SCLG_YXDXMB;
select * from user_tab_cols where table_name = 'T_ADEV_SCLG_YXDXMB'; #查询名为 'T_ADEV_SCLG_YXDXMB' 的表的列信息，包括列名、数据类型、约束等。select * from user_col_comments where table_name = 'T_ADEV_SCLG_YXDXMB'; #查询名为 'T_ADEV_SCLG_YXDXMB' 的表的列注释信息。
