RaigorJiang opened a new issue, #22925:
URL: https://github.com/apache/shardingsphere/issues/22925
### Which version of ShardingSphere did you use?
master 6f625cf7
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Provide accurate message when wrong strategy type is specified in `CREATE
SHARDING TABLE RULE` statement.
### Actual behavior
Sharding strategy type only supports `standard`, `complex`, `hint`, but when
I specify `error`, I cannot get accurate error message.
```sql
mysql> CREATE SHARDING TABLE RULE t_order_item (
-> DATANODES("ds_${0..1}.t_order_item"),
->
DATABASE_STRATEGY(TYPE="ERROR",SHARDING_COLUMN=user_id,SHARDING_ALGORITHM(TYPE(NAME="inline",PROPERTIES("algorithm-expression"="ds_${user_id
% 2}"))))
-> );
ERROR 19150 (44000): Invalid sharding_db algorithms `[inline]`.
mysql>
```
Invalid strategy type `error` should be prompted here, not the algorithm
name.
