Continuous Interval Functions for unsupported data types needs to be optimized,
for example, (index:0) need to indicate which timeseries datatype does not
match.
{code:java}
IoTDB> show timeseries root.sg.d1.*;
+-------------+-----+--------+--------+--------+-----------+----+----------+
| Timeseries|Alias|Database|DataType|Encoding|Compression|Tags|Attributes|
+-------------+-----+--------+--------+--------+-----------+----+----------+
|root.sg.d1.s3| null| root.sg| TEXT| PLAIN| SNAPPY|null| null|
|root.sg.d1.s1| null| root.sg| INT64| RLE| SNAPPY|null| null|
|root.sg.d1.s2| null| root.sg| FLOAT| RLE| SNAPPY|null| null|
+-------------+-----+--------+--------+--------+-----------+----+----------+
Total line number = 3
It costs 0.004s
IoTDB> select zero_duration(s3) from root.sg.d1;
Msg: 416: Error occurred during inferring UDF data type:
