test step:
# delete all storage
# exec the below sql:
SET STORAGE GROUP TO root.ln;
CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN,
ENCODING=PLAIN;
CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT,
ENCODING=RLE;
INSERT INTO root.ln.wf01.wt01(timestamp,status,temperature)
values(200,false,20.71);
INSERT INTO root.ln.wf01.wt01(timestamp,status) values(200,true);
3. exec 'show child nodes root.ln'
