      <description>Description The SHOW SHARDING TABLE RULE syntax is used to query the sharding table rule in the specified database.
Syntax ShowShardingTableRule ::= &#39;SHOW&#39; &#39;SHARDING&#39; &#39;TABLE&#39; (&#39;RULE&#39; tableName | &#39;RULES&#39;) (&#39;FROM&#39; databaseName)? tableName ::= identifier databaseName ::= identifier Supplement  When databaseName is not specified, the default is the currently used DATABASE. If DATABASE is not used, No database selected will be prompted.  Return value description    Column Description     table Logical table name   actual_data_nodes Actual data node   actual_data_sources Actual data source (Displayed when creating rules by RDL)   database_strategy_type Database sharding strategy type   database_sharding_column Database sharding column   database_sharding_algorithm_type Database sharding algorithm type   database_sharding_algorithm_props Database sharding algorithm properties   table_strategy_type Table sharding strategy type   table_sharding_column Table sharding column   table_sharding_algorithm_type Table sharding algorithm type   table_sharding_algorithm_props Table sharding algorithm properties   key_generate_column Sharding key generator column   key_generator_type Sharding key generator type   key_generator_props Sharding key generator properties    Example  Query the sharding table rules of the specified logical database  SHOW SHARDING TABLE RULES FROM sharding_db; +--------------+-------------------+---------------------+------------------------+--------------------------+----------------------------------+-----------------------------------+---------------------+-----------------------+-------------------------------+--------------------------------+---------------------+--------------------+---------------------+ | table | actual_data_nodes | actual_data_sources | database_strategy_type | database_sharding_column | database_sharding_algorithm_type | database_sharding_algorithm_props | table_strategy_type | table_sharding_column | table_sharding_algorithm_type | table_sharding_algorithm_props | key_generate_column | key_generator_type | key_generator_props | +--------------+-------------------+---------------------+------------------------+--------------------------+----------------------------------+-----------------------------------+---------------------+-----------------------+-------------------------------+--------------------------------+---------------------+--------------------+---------------------+ | t_order | | ds_0,ds_1 | | | | | mod | order_id | mod | sharding-count=4 | | | | | t_order_item | | ds_0,ds_1 | | | | | mod | order_id | mod | sharding-count=4 | | | | +--------------+-------------------+---------------------+------------------------+--------------------------+----------------------------------+-----------------------------------+---------------------+-----------------------+-------------------------------+--------------------------------+---------------------+--------------------+---------------------+ 2 rows in set (0.</description>
