Introduction to Oracle MINUS Operator# The OracleMINUSoperator compares two queries and returnsdistinctrows from the firstquerythat are not output by the second query. In other words, theMINUSoperator subtracts one result set from another.
You can combine set operators to implement a classic use case: Comparing two tables, returning a list of all the values that only exist in one table. This is also known as the symmetric difference. There isn't a native operator that does this. But you can do it by: ...
To comply with emerging SQL standards, a future release of Oracle will give theINTERSECToperator greater precedence than the other set operators. Therefore, you should use parentheses to specify order of evaluation in queries that use theINTERSECToperator with other set operators. The following example...
The UNION operator returns only distinct rows that appear in either result, while the UNION ALL operator returns all rows. The UNION ALL operator does not eliminate duplicate selected rows: select empno,ename from emp union allselect empno,ename from oldemp;...
To comply with emerging SQL standards, a future release of Oracle will give the INTERSECT operator greater precedence than the other set operators. Therefore, you should use parentheses to specify order of evaluation in queries that use the INTERSECT operator with other set operators. UNION Example...
