Considerations when using the INTERSECT function

Intersect is not commutative. That means, Intersect (T1, T2) can have a different result set than Intersect (T2, T1).
Duplicate rows are retained. That means, if a row appears in table_expression1 and table_expression2, it and all duplicates in table_expression_1 are included in the result set.
The column names will match the column names in table_expression1.
Columns are compared based on the positioning, and data comparison with no type coercion.
The returned table does not include columns from the tables related to table_expression1.
