Hello:
I've the following question:
I need to create a column, where the information is conserved in the same
way that it was written by the user, but the data of this column is unique
if it's only taken to capital
declaring a constraint
... unique(column name) is not enough to me 'cause
'ab'
'AB'
'aB'
....
will be accepted
Thanks in advance for any help
