1.查看获取表内字段注释：
show full columns from tablename;show full fields from tablename;或是，在元数据的表里面看
select COLUMN_NAME 列名, DATA_TYPE 字段类型, COLUMN_COMMENT 字段注释
from INFORMATION_SCHEMA.COLUMNS
Where table_name = 'companies'##表名
AND table_schema = 'testhuicard'##数据库名
AND column_name LIKE 'c_name'##字段名查看表注释的方法：
show create table tablename;修改表的注释:
alter table test1 comment '修改后的表的注释';修改字段的注释:
alter table test1 modify column field_name int comment '修改后的字段注释';Posted by kk
