heavyai-rs's Issues

examples/query_print only prints integers

Hey JraJav,

When trying to run query_print main.rs I only get integers, 0's and "NULL"

When I cargo run main.rs with only changing line 58 in main.rs to
let query = "SELECT * FROM flights_2008_10k LIMIT 1".to_string();
and line 8 in Cargo.toml to omnisci = "0.1.0"

[dependencies]
omnisci = "0.1.0"

I get

connecting to server on 127.0.0.1:6274...

If I run in Omnisql
