   ### Which version of ShardingSphere did you use?
   4.0.0-RC2 4.0.0-RC3
   
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   Sharding-JDBC
   
   ### Expected behavior
   ```sql
   CREATE TABLE IF NOT EXISTS board (id BIGINT PRIMARY KEY, author_id BIGINT NOT NULL, title VARCHAR(100) NOT NULL, description VARCHAR(1000) NOT NULL, status INT NOT NULL, accessibility INT NOT NULL, create_time DATETIME(6) NOT NULL, update_time DATETIME(6) NOT NULL)
   ```
   
   Failed.
   
   ### Actual behavior
   It should create the table.
   
   ### Reason analyze (If you can)
   `StreamQueryResult`  did not consider `resultSet` to be null. When executing create table sql, resultSet will be null.
   
   ```java
   public final class StreamQueryResult implements QueryResult {
       
       private final QueryResultMetaData metaData;
       
       private final ResultSet resultSet;
       
       @SneakyThrows
       public StreamQueryResult(final ResultSet resultSet, final ShardingRule shardingRule) {
           this.resultSet = resultSet;
           metaData = new QueryResultMetaData(resultSet.getMetaData(), shardingRule);
       }
       
       @SneakyThrows
       public StreamQueryResult(final ResultSet resultSet, final EncryptRule encryptRule) {
           this.resultSet = resultSet;
           metaData = new QueryResultMetaData(resultSet.getMetaData(), encryptRule);
       }
       
       @SneakyThrows
       public StreamQueryResult(final ResultSet resultSet) {
           this.resultSet = resultSet;
           metaData = new QueryResultMetaData(resultSet.getMetaData());
       }
       
   ```
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   Execute the following sql should reproduce the problem.
   
   ```sql
   CREATE TABLE IF NOT EXISTS board (id BIGINT PRIMARY KEY, author_id BIGINT NOT NULL, title VARCHAR(100) NOT NULL, description VARCHAR(1000) NOT NULL, status INT NOT NULL, accessibility INT NOT NULL, create_time DATETIME(6) NOT NULL, update_time DATETIME(6) NOT NULL)
   ```
   
   ### Example codes for reproduce this issue (such as a github link).
