Solution 1

Please clarify your question.
If you want to fetch those records that Emp_Id and Email is same,
the your query is right.

SQL

SELECT * FROM tablename WHERE col1= col2

Solution 2

Or do you mean that you want to compare two different fields with different values. So something like?

SQL

select *
from   yourtable
where  column1 = 'A'
and    column2 = 'B'

Solution 3

If you want to return a predefined value based on the equality of two fields in a row, you have to use case statements like this:

SQL

select case when Emp_Id = Email then 'equals' else 'not equals' end from SendP
