It's not that difficult. did you try? BTW, you have not mentioned about any existence of Primary Key. If it is there, it would be very simple. Try "NOT IN"

from your example, is there any similarities between tableA and tableB ?
and what is the nature of similarities ? do they have common columns ?

You can use on of the datacompare tools if you are comparing complex schemas

There are tons of other tools, if you are trying to solve a complex comparision.

otherwise, you can simply load data into datasets and compare them using code. Its much easy to do so.
