    The field's data type
  - isNull
```
@Support
Condition isNull()
```
    Check if this row value expression contains only NULL values.
    Row NULL predicates can be simulated in those databases that do not support such predicates natively: (A, B) IS NULL is equivalent to A IS NULL AND B IS NULL
  - isNotNull
```
@Support
Condition isNotNull()
```
    Check if this row value expression contains no NULL values.
    Row NOT NULL predicates can be simulated in those databases that do not support such predicates natively: (A, B) IS NOT NULL is equivalent to A IS NOT NULL AND B IS NOT NULL
    Note that the two following predicates are NOT equivalent:
    - (A, B) IS NOT NULL, which is the same as (A IS NOT NULL) AND (B IS NOT NULL)
    - NOT((A, B) IS NULL), which is the same as (A IS NOT NULL) OR (B IS NOT NULL)
