the reason is my clickhouse table feilds using Decimal(30,3), when i use column.NewDecimal64(3, false) for Decimal(30,3) column, the issue will got. after i change the field type to Decimal64(3) in clickhouse, running as expected.

@harryhan1989 thanks. I know it's annoying that chconn doesn't check the ClickHouse column type and just reads data.
I'm working on the v2 new version that uses Golang 1.18 generic. it's more simple and has some check these inputs to not happen these errors.
