[Rust] [DataFusion] CLI is not working as expected

[asfimport]

I'm testing the CLI and it appears almost unusable.

We should at least improve the error messages for common errors.

 

> CREATE EXTERNAL TABLE taxi 
STORED AS PARQUET
LOCATION '/mnt/nyctaxi/tripdata.parquet'
;
0 rows in set.
> SELECT COUNT(*) FROM taxi;
General("General(\"Can\\\'t build array reader without columns!\")")
 

 

> SELECT COUNT(*) FROM aggregate_test_100;

ArrowError(InvalidArgumentError("at least one column must be defined to create a record batch"))
 

 

 > SELECT * FROM taxi LIMIT 1;
General("InvalidArgumentError(\"column types must match schema types, expected Timestamp(Microsecond, None) but found UInt64 at column index 1\")")

Andy Grove / @andygrove:
The issues are not specific to the CLI but due to bugs in the SQL support specifically with wildcard expressions. I filed separate issues.
