Question

在Oracle 10g中，如何选择不适合多个范围的值。例如：

鉴于数字：

5， 10， 20， 26， 40， 50， 55， 60， 100， 200， 203， 211， 230

范围：

10 - 25

50 - 55

200 - 210

以下数字不适合范围：

5 26 40 60 100 211 230

测试数据：

CREATE TABLE myseries (start_sequence NUMBER(6), end_sequence NUMBER(6));

CREATE TABLE myvalues (sequence_number NUMBER(6));

INSERT INTO myseries VALUES(10,25);

INSERT INTO myseries VALUES(50,55);

INSERT INTO myseries VALUES(200,210);

-- Insert test data
INSERT INTO myvalues VALUES(5);
INSERT INTO myvalues VALUES(10);
INSERT INTO myvalues VALUES(20);
INSERT INTO myvalues VALUES(26);
INSERT INTO myvalues VALUES(40);
INSERT INTO myvalues VALUES(50);
INSERT INTO myvalues VALUES(55);
INSERT INTO myvalues VALUES(60);
INSERT INTO myvalues VALUES(100);
INSERT INTO myvalues VALUES(200);
INSERT INTO myvalues VALUES(203);
INSERT INTO myvalues VALUES(211);
INSERT INTO myvalues VALUES(230);

select sequence_number from myvalues
where sequence_number not in (??)

Answer 1

select sequence_number from myvalues m
where not exists
 ( select 1 from myseries s where m.sequence_number between s.start_sequence
   and s.end_sequence )

选择Oracle中多个数字系列中不存在的数字
