Hi,
When using SQL Server and allowing NULL in empty dates I came across a small issue where EMPTY( date_field) returns .F. when the entry in date_field is NULL. And this of course breaks a lot of code where the program relied on the date field being empty. I am thinking of creating a simple function like this:
Function MyEmpty
lparameter tDate
if empty( tDate) or isnull( tDate)
return .T.
else
return .F.
endif
And replace everywhere in the program where I use
if EMPTY( date_field )
with
if MyEmpty( date_field )
Can anybody see a potential problem with the above approach? TIA.
