这是我的串行表。它有超过1000条记录。具有起始编号和结束编号。但数字之间不存在。 我需要添加所有数字[开始/介于&之间结束号码]另一个临时表中记录按号码编号 如下所示
EXIST TABLE
select concat(CARD_BULK_CODE,start_serial) startserial,concat(CARD_BULK_CODE,end_serial) endserial
from TSR_BULK_CARD_SERIALS
--------------------------- STARTSERIAL ENDSERIAL | --------------------------- 18126944 18126946 | 18141101 18141122 | 15150722 15150729 | 19069303 19069317 | ---------------------------
必填表
----------- SERIAL_NO | ----------- 18126944 18126945 18141101 18141102 .... -----------
似乎需要pl-sql来实现这一点。 请帮我解决这个问题
我在dual的帮助下尝试了以下查询。 但它非常缓慢但尚未得到结果:-)运行超过1小时
select distinct concat(t.CARD_BULK_CODE,t.START_SERIAL)+level-1 SERIAL
from TSR_BULK_CARD_SERIALS t, dual
connect by level-1<=(concat(t.CARD_BULK_CODE,t.END_SERIAL ))-concat(t.CARD_BULK_CODE,t.START_SERIAL)
order by 1
编辑:
亲爱的Alen&amp; Dba.i尝试了你的问题,并且发生了以下错误。
DECLARE
l_st NUMBER;
l_en NUMBER;
BEGIN
FOR rec IN (select concat(card_bulk_code, start_serial) startserial,concat(card_bulk_code, end_serial) endserial from tsr_bulk_card_serials)
LOOP
l_st := rec.startserial;
l_en := rec.endserial;
FOR rec1 IN l_st..l_en
LOOP
INSERT INTO temp(serial_no) values(rec1);
END LOOP;
END LOOP;
COMMIT;
END;

一种方法,无需借助plsql
WITH ranges AS
(
SELECT CONCAT(CARD_BULK_CODE, start_serial) startserial,
CONCAT(CARD_BULK_CODE, end_serial) endserial
FROM TSR_BULK_CARD_SERIALS
),
numbers(n) AS (
SELECT 0 n
FROM dual
UNION ALL
SELECT n + 1
FROM numbers
WHERE n <=
(
SELECT MAX(endserial - startserial)
FROM ranges
)
)
SELECT t.startserial + n.n SERIAL_NO
FROM ranges t JOIN numbers n
ON n.n <= t.endserial - t.startserial
ORDER BY SERIAL_NO
这是 SQLFiddle 演示

试试这个,
WITH t(ST, EN) AS
(
SELECT 18126944, 18126946 FROM dual
UNION
SELECT 18141101, 18141122 FROM dual
UNION
SELECT 15150722, 15150729 FROM dual
UNION
SELECT 19069303 , 19069317 FROM dual
)
SELECT DISTINCT st + LEVEL -1
FROM t
CONNECT BY LEVEL <= (SELECT en - st + 1 FROM DUAL)
ORDER BY 1;
/
为PL / SQL尝试类似的东西,
DECLARE
l_st NUMBER;
l_en NUMBER;
BEGIN
FOR rec IN (SELECT * FROM t)
LOOP
l_st := rec.st;
l_en := rec.en;
FOR rec1 IN l_st..l_en
LOOP
INSERT INTO <your_tab>;
END LOOP;
END LOOP;
COMMIT;
END;
答案 2 :(得分:1)
只需编写一些PL / SQL - 遍历表并在临时表中插入行。
declare
l_start number;
l_end number;
begin
for r_rec in (select to_number(concat(card_bulk_code, start_serial)) startserial
, to_number(concat(card_bulk_code, end_serial)) endserial
from tsr_bulk_card_serials )
loop
l_start := r_rec.startserial;
l_end := r_rec.endserial;
for l_i in l_start..l_end loop
insert into your_temp_table;
end loop;
end loop;
end;
答案 3 :(得分:0)
DECLARE
l_st NUMBER (20);
l_en NUMBER (20);
testnum NUMBER (4);
BEGIN
FOR rec IN (SELECT CONCAT (card_bulk_code, start_serial) startserial,CONCAT (card_bulk_code, end_serial) endserial FROM tsr_bulk_card_serials)
LOOP
l_st := TO_NUMBER (rec.startserial);
l_en := TO_NUMBER (rec.endserial);
testnum := l_en - l_st;
DBMS_OUTPUT.put_line (l_st);
DBMS_OUTPUT.put_line (l_en);
IF l_st < l_en
THEN
FOR rec1 IN 0 .. testnum
LOOP
l_st := l_st + 1;
INSERT INTO temp(serial_no) VALUES (l_st);
END LOOP;
END IF;
END LOOP;
COMMIT;
END;
上面的代码帮助我解决了我的问题 谢谢大家: - )
