Differences between UNIQUE and DISTINCT in select statements


Answer

the diff between unique and distinct is
unique is applied before insertion and retrival.it consists
of non duplicate values.if unique constraint is given it
does not take duplicate values.distinct is used in retrival
it gives the suppressed row(ex if two rows are same it will
show single row and non duplicate row) therefore distinct is
the combination of suppressed duplicate and non duplicate rows.
