Dose it support datetime64?

[doowonee]

I use the latest version which is 1.0.0-alpha.1 cause tokio 1.x

Here is the code to use DateTime64

        block
            .push(row! {
                time_col: DateTime64(row_data.event_at.timestamp_millis(), (3, UTC))
..........
            })

But It crashed like below

thread 'main' panicked at 'not implemented', /home/doowonee/.cargo/registry/src/github.com-1ecc6299db9ec823/clickhouse-rs-1.0.0-alpha.1/src/types/column/datetime64.rs:53:9

And I see the source code and It was not implemented yet

impl ColumnData for DateTime64ColumnData {
    fn sql_type(&self) -> SqlType {
        let (precision, tz) = self.params;
        SqlType::DateTime(DateTimeType::DateTime64(precision, tz))
    }

    fn save(&self, _encoder: &mut Encoder, _start: usize, _end: usize) {
        unimplemented!()
    }

Am I using wrong?

same issue

[mplanchard]

anybody figure this out? I can't figure out how to insert a DateTime64 column

[suharev7]

You can see examples of how to insert DateTime64 into tests. For example, here or here.
