execute the following sql:
```
CREATE DATABASE root.sg_type;
CREATE TIMESERIES root.sg_type.d_0.s_boolean BOOLEAN;
CREATE TIMESERIES root.sg_type.d_0.s_int32 INT32;
CREATE TIMESERIES root.sg_type.d_0.s_int64 INT64;
CREATE TIMESERIES root.sg_type.d_0.s_float FLOAT;
CREATE TIMESERIES root.sg_type.d_0.s_double DOUBLE;
CREATE TIMESERIES root.sg_type.d_0.s_text TEXT;
CREATE TIMESERIES root.sg_type.d_0.s_timestamp TIMESTAMP;
CREATE TIMESERIES root.sg_type.d_0.s_date DATE;
CREATE TIMESERIES root.sg_type.d_0.s_blob BLOB;
CREATE TIMESERIES root.sg_type.d_0.s_string STRING;
INSERT INTO root.sg_type.d_0(time, s_int32, s_int64, s_float, s_double, s_text)
VALUES (0, 0, 0, 0.000000, 0.000000, 'text0');
```
we don't insert s_boolean, so we should get null, but we still get false
