ICannerxy opened a new issue, #21653:
URL: https://github.com/apache/shardingsphere/issues/21653
## Bug Report
### Which version of ShardingSphere did you use?
5.2.0
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Support JDBC Statement addBatch() and executeBatch();
### Actual behavior
When using jdbc to batch delete data, the expected and actual results are
inconsistent.
### Reason analyze (If you can)
Maybe is a bug.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
1. Table t1 has 2 sub databases and 2 sub tables
```sql
CREATE TABLE `t1` (
`id` int(11) DEFAULT NULL,
`name` varchar(222) DEFAULT NULL
) ENGINE=InnoDB
```
2. insert into t1
values(1,1),(2,2),(3,3),(4,4),(5,5),(6,6),(7,7),(8,8),(9,9);
3.
```
public static void main(String[] args) {
Connection con = null;
PreparedStatement statement = null;
try {
String user = "root";
String password = "servyou";
String url =
"jdbc:mysql://10.199.157.228:3307/datarktest?useUnicode=true&useSSL=true&characterEncoding=utf8&allowMultiQueries=true&rewriteBatchedStatements=true&useServerPrepStmts=true";
String driver = "com.mysql.cj.jdbc.Driver";
//2.加载驱动
Class.forName(driver);
//3.获取连接
con = DriverManager.getConnection(url, user, password);
con.setAutoCommit(false);
statement = con.prepareStatement("delete from t1 where id = ?");
statement.setInt(1, 1);
statement.addBatch();
statement.setInt(1, 2);
statement.addBatch();
statement.setInt(1, 3);
statement.addBatch();
statement.setInt(1, 4);
statement.addBatch();
statement.setInt(1, 5);
statement.addBatch();
statement.setInt(1, 6);
statement.addBatch();
statement.setInt(1, 7);
statement.addBatch();
statement.setInt(1, 8);
statement.addBatch();
statement.setInt(1, 9);
statement.addBatch();
//6.执行操作
statement.executeBatch();
con.commit();
} catch (Exception e) {
e.printStackTrace();
} finally {
//7.资源的关闭
try {
statement.close();
} catch (SQLException e) {
e.printStackTrace();
}
try {
con.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
```
It is expected that all the data in the table will be deleted, but it is not
