Only a few operand positions are affected by the fact that character-like date fields and time fields contain a local date in the format "yyyymmdd" or a local time in the format "hhmmss":
In all other operand positions, the handling of character-like date fields and time fields is specified in the conversion rules and comparison rules for these data types.
Direct assignments or comparisons between the data types d and t are meaningless and therefore forbidden. The following sections show examples of how to access character-like date fields and time fields effectively.
Note
The function modules of the function group SCAL provide some additional information about character-like dates, for example the day of the week or the calendar week for a given date.
