Hello,
Two patches included:- the first one enables the use of bool variables in fields which mightbecome NULL. Up to now the lib told you that NULL is not a bool variable, even ifyou provide a indicator.- the second patch checks whether a value is null and issues an error ifno indicator is provided.Sidenote: IIRC, the variable should be left alone if the value is NULL.ECPGlib sets it's value to 0 on NULL. Is this a violation of thestandard?Regards Christof
