| <description>Description The CREATE SHARDING BINDING TABLE RULE syntax is used to add binding relationships and create binding table rules for tables with sharding table rules |
| Syntax CreateBindingTableRule ::= &#39;CREATE&#39; &#39;SHARDING&#39; &#39;BINDING&#39; &#39;TABLE&#39; &#39;RULES&#39; bindingTableDefinition (&#39;,&#39; bindingTableDefinition )* bindingTableDefinition ::= &#39;(&#39; tableName (&#39;,&#39; tableName)* &#39;)&#39; tableName ::= identifier Supplement Creating binding relationships rules can only use sharding tables; A sharding table can only have one binding relationships; The sharding table for creating binding relationships needs to use the same resources and the same actual tables.</description> |

| <description>Description The CREATE SHARDING BROADCAST TABLE RULE syntax is used to create broadcast table rules for tables that need to be broadcast (broadcast tables) |
| Syntax CreateBroadcastTableRule ::= &#39;CREATE&#39; &#39;SHARDING&#39; &#39;BROADCAST&#39; &#39;TABLE&#39; &#39;RULES&#39; &#39;(&#39; tableName (&#39;,&#39; tableName)* &#39;)&#39; tableName ::= identifier Supplement tableName can use an existing table or a table that will be created; Only one broadcast rule can exist, but can contain multiple broadcast tables, so can not execute CREATE SHARDING BROADCAST TABLE RULE more than one time.</description> |
