oracle 多個(gè)字符替換實(shí)現(xiàn)
更新時(shí)間：2009年10月21日 22:09:36 作者：
CSDN上的一個(gè)網(wǎng)友，需要一個(gè)sql語(yǔ)句的解決方案需求是這樣的求寫(xiě)oracle多個(gè)字符替換（有測(cè)試數(shù)據(jù)）
復(fù)制代碼 代碼如下:
create table A_TEST
(
PAYOUT_ITEM_CODE VARCHAR2(30) not null,
FORMULA_DET VARCHAR2(1000)
)
create table B_TEST
(
ELEMENT_ID VARCHAR2(5) not null,
NAME VARCHAR2(41)
)
FORMULA_DET列里ELEMENT_ID替換成NAME
測(cè)試數(shù)據(jù)如下
復(fù)制代碼 代碼如下:

這個(gè)如果用function或者是sp做，就沒(méi)有什么難度了。
但是用sql做就比較難度了
復(fù)制代碼 代碼如下:
select gid, payout_item_code, formula_det, max(substr(txt, 1, length(txt)-1)) from (
select a.gid,
a.payout_item_code,
a.formula_det,
replace(sys_connect_by_path(decode(b.element_id, null, a.signal, replace(signal, b.element_id, b.name)),'##'), '##', '') txt
from
(select gid, payout_item_code, formula_det, row_number() over(partition by gid order by level) rn,
substr(formula_det, decode(rownum-(allcnt-selfcnt), 1, 1, instr(formula_det, '}', 1, rownum-(allcnt-selfcnt)-1)+1), instr(formula_det, '}', 1, rownum-(allcnt-selfcnt))-decode(rownum-(allcnt-selfcnt), 1, 0, instr(formula_det, '}', 1, rownum-(allcnt-selfcnt)-1))) signal
from (select a.payout_item_code, a.rowid gid,

from a_test a) t1
start with (allcnt-selfcnt)=0 connect by rownum < sumcnt+1 and instr(formula_det, '}', 1, rownum-(allcnt-selfcnt)) >0) a
left join b_test b on instr(a.signal||'}', '{'||b.element_id||'}', 1, 1)>0
start with a.rn = 1 connect by prior a.gid = a.gid and prior a.rn + 1 = a.rn)
group by gid, payout_item_code, formula_det
