You can use the minus keyword
Source table name is A
Target table name is B.
Query can be
select * from B
minus
select * from A
or else you can do a minus from A to B.
select * from A
minus
select * from B
Inthis way you can find the mismatch
(Note: This is just one way pf comparing)

If both exist in same database then you can use NOT EXIST
function to find out the missing rows.
If both exist in diff databases then you can join them using
joiner and compare the rows in expression and Raise a Flag
for not matching rows.You can then use filter and pass only
the non matching rows into the target.

We can use lookup transformation to stay away from these
problem and can lookup the target columns befor entering the
data.
