我给oracle视图的列加了注释，如下
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_DICT_ID is ‘物资字典ID’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.ATTR_ID is ‘物资属性ID’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_CODE is ‘物资代码’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_NAME is ‘物资名称’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_SPEC is ‘规格’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_MODEL is ‘物资型号’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_BRAND is ‘物资品牌’;
comment on column HRP_1001.V_MTRL_DICT_LIST_TOTAL.MTRL_STATUS is ‘停用标志’;
但是却不知道怎么查看这些列的注释，我用user_col_comments 却查看不到，不知道应该怎么看：
SQL> select * from user_col_comments where TABLE_NAME=‘V_MTRL_DICT_LIST_TOTAL_QY’;
TABLE_NAME COLUMN_NAME COMMENTS
V_MTRL_DICT_LIST_TOTAL_QY MTRL_DICT_ID
V_MTRL_DICT_LIST_TOTAL_QY ATTR_ID
V_MTRL_DICT_LIST_TOTAL_QY ATTR_NAME
V_MTRL_DICT_LIST_TOTAL_QY MTRL_CODE
V_MTRL_DICT_LIST_TOTAL_QY MTRL_NAME
V_MTRL_DICT_LIST_TOTAL_QY MTRL_SPEC
V_MTRL_DICT_LIST_TOTAL_QY MTRL_MODEL
V_MTRL_DICT_LIST_TOTAL_QY MTRL_BRAND
V_MTRL_DICT_LIST_TOTAL_QY UNITS
V_MTRL_DICT_LIST_TOTAL_QY UNITS_NAME
V_MTRL_DICT_LIST_TOTAL_QY MTRL_STATUS
DBA_COL_COMMENTS displays comments on the columns of all tables and views in the database.
ALL_COL_COMMENTS displays comments on the columns of the tables and views accessible to the current user.
USER_COL_COMMENTS displays comments on the columns of the tables and views owned by the current user. This view does not display the OWNER column.

有用 0DBA_COL_COMMENTS 、ALL_COL_COMMENTS 、USER_COL_COMMENTS
这三个都查不到视图 列的注释。
那看来oracle没办法查看视图的注释，加注释没用
评论 有用 0我自己测试结果，可以看到注释呀。
