In Session, the JDBC module can set the Boolean return data type to 0/1 or true/false.

可以通过在 Session，JDBC模块中可以设置Boolean的返回数据类型为0/1或true/false
In Session, the JDBC module can set the Boolean return data type to 0/1 or true/false.

SessionExample

Map<String,String> map = new HashMap<>();
map.put("boolFormat", "number");
//map.put("boolFormat", "bool");
session = new Session("127.0.0.1", 6667, "root", "root",map);

JDBCExample

Connection connection = DriverManager.getConnection("jdbc:iotdb://127.0.0.1:6667/?boolFormat=number", "root", "root");
// Connection connection = DriverManager.getConnection("jdbc:iotdb://127.0.0.1:6667/?boolFormat=bool", "root", "root");

将来需要传输多个参数也能支持如：
The need to transfer multiple parameters in the future can also be supported such as：
SessionExample

Map<String,String> map = new HashMap<>();
map.put("boolFormat", "number");
map.put("key", "value");
session = new Session("127.0.0.1", 6667, "root", "root",map);

JDBCExample

Connection connection = DriverManager.getConnection("jdbc:iotdb://127.0.0.1:6667/?boolFormat=number&&key=value", "root", "root");

Very good job. I marked some format issues. It will be great if you fix them.
Also, I think it's necessary to add these interface changes into User Guide docs to tell users.
By the way, the Travis CI has many errors, please fix them. Big thanks!

There is also a conflict needs to be fixed.

CI failed, please take a look.

Good work! Please add ITs in jdbc and Session module. And update the docs/UserGuide/Client and docs/UserGuide/zh/Client.

Hi, I think we should not change the type of Field. This issue only changes how the getString() method returns data.

[qiaojialin]

Hi, you could use the SessionDataSet.Iterator() to get the iterator and use the iterator.getString() that triggers the config.

If we don't indicate ?boolFormat=bool, is there any problem?
If not, I think we'd better keep the old example to show we don't have to do such setting when getting a normal JDBC connection.
