sandynz opened a new issue, #16331:
URL: https://github.com/apache/shardingsphere/issues/16331
## Bug Report
### Which version of ShardingSphere did you use?
master branch, commit d71cac1c6d43eeda8906469ac504226416ceb14c
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
It works before, seems it's affected by PR #16172, I'm not sure whether it's
bug or not.
### Actual behavior
SQL:
```
mysql> CREATE SHARDING BINDING TABLE RULES (bmsql_customer,bmsql_warehouse);
ERROR 1117 (C1117): Invalid binding rule [bmsql_customer,bmsql_warehouse],
error messages are: [Unable to bind different sharding strategies].
```
Exception stack trace:
```
org.apache.shardingsphere.infra.distsql.exception.rule.InvalidRuleConfigurationException:
Invalid binding rule [bmsql_customer,bmsql_warehouse], error messages are:
[Unable to bind different sharding strategies].

### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
I'm testing BenchmarkSQL in Proxy, since there's join query, so I need to
set binding tables. sql:
```
stmtNewOrderSelectWhseCust = dbConn.prepareStatement(
"SELECT c_discount, c_last, c_credit, w_tax " +
" FROM bmsql_customer " +
" JOIN bmsql_warehouse ON (w_id = c_w_id) " +
" WHERE c_w_id = ? AND c_d_id = ? AND c_id = ?");
```
Execute following SQLs on MySQL client (connected to Proxy):
```
create database scaling_bmsql2;
use scaling_bmsql2
ADD RESOURCE ds_0 (
URL="jdbc:mysql://127.0.0.1:3306/scaling_bmsql1?serverTimezone=UTC&useSSL=false",
USER=root,
PASSWORD=root,
PROPERTIES("maximumPoolSize"=50,"idleTimeout"="60000")
), ds_1 (
URL="jdbc:mysql://127.0.0.1:3306/scaling_bmsql2?serverTimezone=UTC&useSSL=false",
USER=root,
PASSWORD=root,
PROPERTIES("maximumPoolSize"=50,"idleTimeout"="60000")
);
CREATE SHARDING TABLE RULE bmsql_warehouse(
RESOURCES(ds_0,ds_1),
SHARDING_COLUMN=w_id,
TYPE(NAME=hash_mod,PROPERTIES("sharding-count"=2)),
KEY_GENERATE_STRATEGY(COLUMN=w_id,TYPE(NAME=snowflake))
), bmsql_customer(
RESOURCES(ds_0,ds_1),
SHARDING_COLUMN=c_w_id,
TYPE(NAME=hash_mod,PROPERTIES("sharding-count"=2)),
KEY_GENERATE_STRATEGY(COLUMN=c_w_id,TYPE(NAME=snowflake))
);
CREATE SHARDING BINDING TABLE RULES (bmsql_customer,bmsql_warehouse);
```
