Alias in data validation rules
Versions des environnements
Hi,
In VFP9 help, under the topic Field and Record Validation Rules which discusses data validation rules, a Note:
"When a trigger is called, the Alias is always that of the cursor being updated, regardless of the Alias selected in the code that caused the trigger to fire."
What is the Alias in the above note?
Does it mean in the validation rule, if I have abc = ALIAS(), abc will be assigned the alias of the cursor which contains the field being validated (instead of active workarea alias when the validation check is triggered)?
