Hi Citlali,
Go to google, and search for 'Oracle' and 'bitand'
The link to Jonathan Lewis' site (2nd result of the Google search) is
quite helpful.
Think out of the box. Your negation operation is like an XOR with a
string of '1' bits of the same length.
So, something along the lines of:
flag AND (4589 XOR 1111111111111)
should do the job.
Best regards,
Carel-Jan Engel
