shihuizhen opened a new issue #7922:
URL: https://github.com/apache/shardingsphere/issues/7922
example:
table:
CREATE TABLE `t_order_item` (
`item_id` bigint(20) NOT NULL,
`order_id` bigint(20) unsigned DEFAULT NULL,
`user_id` int(11) NOT NULL,
`status` varchar(45) DEFAULT NULL,
`creation_date` date DEFAULT NULL,
PRIMARY KEY (`item_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4
config_sharding:
shardingRule:
tables:
t_order:
actualDataNodes: ds_${0..5}.t_order_${0..1}
tableStrategy:
inline:
shardingColumn: order_id
algorithmExpression: t_order_${order_id % 2}
# keyGenerator:
# type: SNOWFLAKE
# column: order_id
t_order_item:
actualDataNodes: ds_${0..5}.t_order_item_${0..1}
tableStrategy:
inline:
shardingColumn: order_id
algorithmExpression: t_order_item_${order_id % 2}
keyGenerator:
type: SNOWFLAKE
column: item_id
case1:
INSERT INTO t_order_item(order_id,user_id,status,creation_date) VALUES
(2111,21,' init',' 2017-08-31');
select @@IDENTITY as insert_id from t_order_item;
result is not correct!
case2:
INSERT INTO t_order_item(order_id,user_id,status,creation_date) VALUES
(2111,21,' init',' 2017-08-31');
SELECT LAST_INSERT_ID();
result is not correct!
