`WITH FILL` can be applied for fields with Numeric (all kind of float, decimal, int) or Date/DateTime types. When applied for `String` fields, missed values are filled with empty strings. `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 `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 `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 and as `seconds` for DateTime type.
