I'm using `clickhouse` for the first time, and when I'm doing import like this:

```
cat /home/data/_XDR_IMPORT_1001_20001010_000001_.tsv | clickhouse-client --password=123 --query="INSERT INTO ts FORMAT TSV";

```

It gives me an error:

> 
> Column 13, name: dpc, type: Nullable(Int32), parsed text: "0"
>  ERROR: garbage after Nullable(Int32): "3242"
> 
> 
> 

And this is because I have a column (dpc) in type Int32 and the value of this column is 03242, so it seems the import process takes only 0 and trying to find the tap after it.

Please help anyone?
