Re: Need HELP WITH NULL HANDLING IN SQLRPGLE --- -- MIDRANGE-L

Jeff,

you showed us the wrong part, we need to change the fetch...

into ...   :LMBRAM :isNullField, ...

you need someplace for the retreive to tell you that the field is null, that
is the indicator variable in the fetch, separated by no comma, this field
will be -1 if the field is null.
