【Oracle sql】用sql獲取表中字段、表注釋和列注釋

建表語句：

create table test02(
    id number(3),
    name nvarchar2(20),
    age number(3),
    primary key(id)
);

COMMENT ON TABLE test02 IS '測試表';
COMMENT ON COLUMN test02.id IS 'ID';
COMMENT ON COLUMN test02.name IS '名字';
COMMENT ON COLUMN test02.age IS '年齡';

獲取表中字段名：

select column_name from user_tab_columns where table_Name=upper('test02');

獲取表注釋：

select comments from user_tab_comments where table_Name=upper('test02');

獲取列名和列注釋：

select column_name,comments from user_col_comments where table_Name=upper('test02');

執行效果：

SQL> select column_name from user_tab_columns where table_Name=upper('test02');
