When FixUps are called in CRecordSets

[rajeessh]

I have got two classes inherited from CRecordSet
Both of them are bound to different read only views in Oracle
Both have been used in the same manner
But Open Call to RecordSet1 calls the internal function FixUps
but the other does not.

Microsoft says that FixUps function will be called in some cases

Can anyone enlighten on when this function FixUps will be called and why it is called.

Thanks
