1.表及分割槽格式化資訊
包含儲存位置、分隔符格式、建立時間等資訊。
describe formatted table_name [PARTITION(partition_desc)];
describe formatted recommend_data_view partition (pt_day='2018-07-19');
describe formatted recommend_data_view;2.表及分割槽的檢視
可以進行模糊查詢。
SHOW TABLES [IN database_name] [identifier_with_wildcards];
SHOW PARTITIONS table_name [PARTITION(partition_desc)];
show tables 're*';
show partitions recommend_data_view partition (pt_day='2018-07-19');3.表及檢視建表語句檢視
SHOW CREATE TABLE ([db_name.]table_name|view_name)
show create table recommend_data_view;4.列資訊檢視
SHOW COLUMNS(FROM|IN) table_name [(FROM|IN) db_name]
show columns in recommend_data_view;5.帶描述列資訊檢視
DESCRIBE [EXTENDED|FORMATTED] [db_name.]table_name PARTITION partition_spec;
desc recommend_data_view;
desc recommend_data_view partition (pt_day='2018-07-19');6.其他方面資訊檢視
SHOW TBLPROPERTIES table_name;
SHOW TBLPROPERTIES table_name ('');
SHOW TBLPROPERTIES recommend_data_view;SHOW TABLE EXTENDED[IN|FROM database_name] LIKE identifier_with_wildcards [PARTITION (partition_desc)]
SHOW TABLE EXTENDED in default LIKE 'recommend_data_view' partition (pt_day='2018-07-19');
