Cause: The select lists to the left and right of a UNION,
INTERSECT, or MINUS expression select at least one column
that is mismatched in datatype. For example, the following
statement is faulty because the constant 3 has datatype
NUMBER, whereas SYSDATE has datatype DATE: CURSOR my_cur IS
SELECT 3 FROM emp INTERSECT SELECT SYSDATE FROM emp;

Action: Change the select lists so that they match in
datatype. You might want to use datatype conversion
functions in the select list of one or more queries.
