hai rag,
we need to go for some logic as we are not sure the increment size of the field which is varying.
but for this i don't think we have any specific feature in SQL for accomplishing this.
please do let me know if you get to know...
kind regards,

hi,
if ur eno follows the sequence...then use cursors...and a variable counter...compare the variable counter with each record fetched by the cursor...and write the missing records to a file..increment the variable counter for every read by the cursor..if ur table is not having duplicates..
