`WITH FILL` can be applied for fields with Numeric (all kinds of float, decimal, int) or Date/DateTime types. When applied for `String` fields, missed values are filled with empty strings.
When `FROM const_expr` not defined sequence of filling use minimal `expr` field value from `ORDER BY`.
When `TO const_expr` not defined sequence of filling use maximum `expr` field value from `ORDER BY`.
When `STEP const_numeric_expr` defined then `const_numeric_expr` interprets `as is` for numeric types as `days` for Date type and as `seconds` for DateTime type.
When `STEP const_numeric_expr` defined then `const_numeric_expr` interprets `as is` for numeric types, as `days` for Date type, as `seconds` for DateTime type. It also supports [INTERVAL](https://clickhouse.com/docs/en/sql-reference/data-types/special-data-types/interval/) data type representing time and date intervals.
When `STEP const_numeric_expr` omitted then sequence of filling use `1.0` for numeric type, `1 day` for Date type and `1 second` for DateTime type.
Example of a query without `WITH FILL`:

The following query uses the `INTERVAL` data type of 1 day for each data filled on column `d1`:
``` sql

toDate(number * 86400) AS d2,
