存储过程查询一张表中记录是否连续、重复并且取出对应的数据
创建主表：MESSAGE1
create table MESSAGE1
(
ID NUMBER not null,
RECEIVE_TIME DATE,
PK_ID NUMBER,
CONTENT VARCHAR2(50)
)
插入测试数据：
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (1, to_date('15-11-2012', 'dd-mm-yyyy'), 1, 'm1');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (2, to_date('16-11-2012', 'dd-mm-yyyy'), 3, 'm3');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (3, to_date('17-11-2012', 'dd-mm-yyyy'), 6, 'm6');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (4, to_date('18-11-2012', 'dd-mm-yyyy'), 1, 'm11');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (5, to_date('19-11-2012', 'dd-mm-yyyy'), 5, 'm15');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (6, to_date('20-11-2012', 'dd-mm-yyyy'), 5, 'm15');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (7, to_date('21-11-2012', 'dd-mm-yyyy'), 6, 'm16');
insert into MESSAGE1 (ID, RECEIVE_TIME, PK_ID, CONTENT)
values (8, to_date('23-11-2012', 'dd-mm-yyyy'), 14, 'm114');
commit;
创建存放不连续数据表：TEST_SERIES1
create table TEST_SERIES1
(
BEGINTIME DATE,
SERIES NUMBER,
ENDTIME DATE
)
创建存放重复数据表：TEST_REPEAT1
create table TEST_REPEAT1
(
BEGINTIME DATE,
REPEAT NUMBER,
ENDTIME DATE
)
创建计算是否连续的存储过程：
create or replace procedure query_series_number_p_date(beginNum in number,
endNum in number) as
t_temp message1%rowtype;
type c_message is ref cursor; --定义变量
cur_message c_message; --声明变量
myIndex number;
cha number;
cha1 number;
--定义array存放将要查询出来的number类型的数据
TYPE emp_ssn_array IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
best_employees emp_ssn_array;
--定义array存放将要查询出来的dsate类型的数据
TYPE emp_ssn_array_p IS TABLE OF date INDEX BY BINARY_INTEGER;
best_employees_p emp_ssn_array_p;
begin
myIndex := 0;
open cur_message for 'select * from message1';
loop
--把查询出来的数据放入array中
fetch cur_message into t_temp;
best_employees(myIndex) := t_temp.pk_id;
best_employees_p(myIndex) := t_temp.receive_time;
myIndex := myIndex + 1;
exit when cur_message%notfound;
end loop;
close cur_message;
FOR i IN 0 .. best_employees.count - 1 LOOP
if i < best_employees.count - 1 then
if (best_employees(i) + 1) != best_employees(i + 1) then
DBMS_OUTPUT.PUT_LINE('不等于');
if (best_employees(i + 1) - best_employees(i)) < 0 then
--判断最后的数字是不是endNum
cha := endNum - best_employees(i);
for j in 1 .. cha loop
insert into test_series1(begintime,series,endtime) values (best_employees_p(i),best_employees(i) + 1 * j,best_employees_p(i+1));
end loop;
--判断刚开始的数字是不是beginNum
cha1 := best_employees(i + 1) - beginNum;
for k in 0 .. cha1 - 1 loop
insert into test_series1(begintime,series,endtime) values (best_employees_p(i),beginNum + 1 * k,best_employees_p(i));
end loop;
else
cha := best_employees(i + 1) - best_employees(i);
for k in 1 .. cha - 1 loop
insert into test_series1(begintime,series,endtime) values (best_employees_p(i),best_employees(i) + 1 * k,best_employees_p(i+1));
end loop;
end if;
end if;
end if;
END LOOP;
end;
创建计算重复的存储过程：
create or replace procedure query_repeat_number_p_date as
t_temp message1%rowtype;
type c_message is ref cursor; --定义变量
cur_message c_message; --声明变量
TYPE emp_ssn_array IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;

best_employees_p emp_ssn_array_p;
myIndex number;
begin
myIndex := 0;
open cur_message for 'select * from message1';
--自动打开游标,执行动态sql
--dbms_output.put_line('工资在'||min_sal||'和'||max_sal||'之间的人有:');
loop
fetch cur_message
into t_temp;
best_employees(myIndex) := t_temp.pk_id;
best_employees_p(myIndex) := t_temp.receive_time;
myIndex := myIndex + 1;
exit when cur_message%notfound;
end loop;
close cur_message;
FOR i IN 0 .. best_employees.count - 1 LOOP
if i < best_employees.count - 2 then
if (best_employees(i)) = best_employees(i + 1) then
--把重复的数据插入表中
insert into test_repeat1(begintime,repeat,endtime) values (best_employees_p(i),best_employees(i),best_employees_p(i+1));
end if;
end if;
END LOOP;
